Formerly called
Don't Make a Wave Committee (1969-1972)[2]

Greenpeace is a non-governmental[3] environmental organization with offices in over forty countries and with an international coordinating body in Amsterdam, the Netherlands.[4] Greenpeace states its goal is to "ensure the ability of the Earth to nurture life in all its diversity"[5] and focuses its campaigning on world wide issues such as climate change, deforestation, overfishing, commercial whaling, genetic engineering, and anti-nuclear issues. It uses direct action, lobbying, and research to achieve its goals. The global organization does not accept funding from governments, corporations, or political parties, relying on 2.9 million individual supporters and foundation grants.[6][7] Greenpeace has a general consultative status with the United Nations Economic and Social Council[8] and is a founding member[9] of the INGO Accountability Charter; an international non-governmental organization that intends to foster accountability and transparency of non-governmental organizations.

Greenpeace is known for its direct actions[10][11] and has been described as the most visible environmental organization in the world.[12][13] Greenpeace has raised environmental issues to public knowledge,[14][15][16] and influenced both the private and the public sector.[17][18] Greenpeace has also been a source of controversy;[19] its motives and methods have received criticism[20][21] and the organization's direct actions have sparked legal actions against Greenpeace activists,[22][23] such as fines and suspended sentences for destroying a test plot of GMO wheat[24][25][26] and damaging the Nazca Lines, a UN World Heritage site in Peru.[27]

History

Origins


Location of Amchitka island in Alaska.

In the late 1960s, the U.S. had plans for an underground nuclear weapon test in the tectonically unstable island of Amchitka in Alaska. Because of the 1964 Alaska earthquake, the plans raised some concerns of the test triggering earthquakes and causing a tsunami. A 1969 demonstration of 7,000[28] people blocked a major U.S.-Canadian border crossing in British Columbia, carrying signs reading "Don't Make A Wave. It's Your Fault If Our Fault Goes".[29] The protests did not stop the U.S. from detonating the bomb.[29]

While no earthquake or tsunami followed the test, the opposition grew when the U.S. announced they would detonate a bomb five times more powerful than the first one. Among the opposers were Jim Bohlen, a veteran who had served in the U.S. Navy, and Irving Stowe and Dorothy Stowe, who had recently become Quakers. As members of the Sierra Club Canada, they were frustrated by the lack of action by the organization.[29] From Irving Stowe, Jim Bohlen learned of a form of passive resistance, "bearing witness", where objectionable activity is protested simply by mere presence.[29]
Jim Bohlen's wife Marie came up with the idea to sail to Amchitka, inspired by the anti-nuclear voyages of Albert Bigelow in 1958. The idea ended up in the press and was linked to The Sierra Club.[29] The Sierra Club did not like this connection and in 1970 The Don't Make a Wave Committee was established for the protest. Early meetings were held in the Shaughnessy home of Robert Hunter and his wife Bobbi Hunter. Subsequently the Stowe home at 2775 Courtenay St. became the HQ.[30] As Rex Weyler put it in his chronology, Greenpeace, in 1969, Irving and Dorothy Stowe's "quiet home on Courtenay Street would soon become a hub of monumental, global significance". Some of the first Greenpeace meetings were held there, and it served as the first office of the Greenpeace Foundation.[citation needed] The first office was opened in a backroom, storefront on Cypress and West Broadway SE corner in Kitsilano, Vancouver.[31]

Irving Stowe arranged a benefit concert (supported by Joan Baez) that took place on October 16, 1970 at the Pacific Coliseum in Vancouver. The concert created the financial basis for the first Greenpeace campaign.[32] Amchitka, the 1970 concert that launched Greenpeace was published by Greenpeace in November 2009 on CD and is also available as an mp3 download via the Amchitka concert website. Using the money raised with the concert, the Don't Make a Wave Committee chartered a ship, the Phyllis Cormack owned and sailed by John Cormack. The ship was renamed Greenpeace for the protest after a term coined by activist Bill Darnell.[29]

In the fall of 1971, the ship sailed towards Amchitka and faced the U.S. Coast Guard ship Confidence[29] which forced the activists to turn back. Because of this and the increasingly bad weather the crew decided to return to Canada only to find out that the news about their journey and reported support from the crew of the Confidence had generated sympathy for their protest.[29] After this Greenpeace tried to navigate to the test site with other vessels, until the U.S. detonated the bomb.[29] The nuclear test was criticized and the U.S. decided not to continue with their test plans at Amchitka.

Founders and founding time of Greenpeace

Environmental historian Frank Zelko dates the formation of the "Don't Make a Wave Committee" to 1969 and according to Jim Bohlen the group adopted the name "Don't Make a Wave Committee" on 28 November 1969.[33] According to the Greenpeace web site, The Don't Make a Wave Committee was established in 1970.[34] Certificate of incorporation of The Don't Make a Wave Committee dates the incorporation to the fifth of October, 1970.[35] Researcher Vanessa Timmer dates the official incorporation to 1971.[36] Greenpeace itself calls the protest voyage of 1971 as "the beginning".[37]
According to Patrick Moore, who was an early member but has since distanced himself from Greenpeace, and Rex Weyler, the name of "The Don't Make a Wave Committee" was officially changed to Greenpeace Foundation in 1972.[35][38] Because of the early phases spanning several years, there are differing views on who can be called the founders of Greenpeace.

Vanessa Timmer has referred to the early members as "an unlikely group of loosely organized protestors".[36] Frank Zelko has commented that "unlike Friends of the Earth, for example, which sprung fully formed from the forehead of David Brower, Greenpeace developed in a more evolutionary manner. There was no single founder".[39] Greenpeace itself says on its web page that "there's a joke that in any bar in Vancouver, Canada, you can sit down next to someone who claims to have founded Greenpeace. In fact, there was no single founder: name, idea, spirit and tactics can all be said to have separate lineages".[34] Patrick Moore has said that "the truth is that Greenpeace was always a work in progress, not something definitively founded like a country or a company. Therefore there are a few shades of gray about who might lay claim to being a founder of Greenpeace."[35] Early Greenpeace director Rex Weyler says on his homepage that the insiders of Greenpeace have debated about the founders since mid-1970's.[40]

The current Greenpeace web site lists the founders of The Don't Make a Wave Committee as Dorothy and Irving Stowe, Marie and Jim Bohlen, Ben and Dorothy Metcalfe, and Robert Hunter.[34] According to both Patrick Moore and an interview with Dorothy Stowe, Dorothy Metcalfe, Jim Bohlen and Robert Hunter, the founders of The Don't Make a Wave Committee were Paul Cote, Irving and Dorothy Stowe and Jim and Marie Bohlen.[35][41]

Paul Watson, founder of the Sea Shepherd Conservation Society maintains that he also was one of the founders of The Don't Make a Wave Committee and Greenpeace.[42] Media sources concerning Watson report him being one of the founders of Greenpeace,[43][44] with many articles reporting him being a founder in 1972.[45][46][47][48] Patrick Moore has denied Watson being one of the founders of The Don't Make a Wave Committee, and Greenpeace in 1972. According to Moore the already campaigning organization was "simply changing the name" in 1972.[35] Greenpeace has stated that Watson was an influential early member, but not one of the founders of Greenpeace.[49] Watson has since criticized Greenpeace of rewriting their history.[42]

Because Patrick Moore was among the crew of the first protest voyage and the beginning of the journey is often referred as the birthday of Greenpeace, Moore also considers himself one of the founders.[35] Greenpeace used to list Moore among "founders and first members" of but has later stated that while Moore was a significant early member, he was not among the founders of Greenpeace in 1970.[41][50]

After Amchitka

After the office in the Stowe home, (and after the first concert fund-raiser) Greenpeace functions moved to other private homes and held public meetings weekly on Wednesday nights at the Kitsilano Neighborhood House before settling, in the fall of 1974, in a small office shared with the SPEC environmental group on West 4th at Maple.[citation needed] When the nuclear tests at Amchitka were over, Greenpeace moved its focus to the French atmospheric nuclear weapons testing at the Moruroa Atoll in French Polynesia. The young organization needed help for their protests and were contacted by David McTaggart, a former businessman living in New Zealand. In 1972 the yacht Vega, a 12.5-metre (41 ft) ketch owned by David McTaggart, was renamed Greenpeace III and sailed in an anti-nuclear protest into the exclusion zone at Moruroa to attempt to disrupt French nuclear testing.
This voyage was sponsored and organized by the New Zealand branch of the Campaign for Nuclear Disarmament.[51] The French Navy tried to stop the protest in several ways, including assaulting David McTaggart. McTaggart was supposedly beaten to the point that he lost sight in one of his eyes. However, one of McTaggart's crew members photographed the incident and went public. After the assault was publicized, France announced it would stop the atmospheric nuclear tests.[29]

In the mid-1970s some Greenpeace members started an independent campaign, Project Ahab, against commercial whaling, since Irving Stowe was against Greenpeace focusing on other issues than nuclear weapons.[citation needed] After Irving Stowe died in 1975, the Phyllis Cormack sailed from Vancouver to face Soviet whalers on the coast of California. Greenpeace activists disrupted the whaling by placing themselves between the harpoons and the whales, and footage of the protests spread across the world. Later in the 1970s, the organization widened its focus to include toxic waste and commercial seal hunting.[29]

The "Greenpeace Declaration of Interdependence" was published by Greenpeace in the Greenpeace Chronicles (Winter 1976-77). This declaration was a condensation of a number of ecological manifestos Bob Hunter had written over the years. The "Three basic Laws of Ecology," were developed by Patrick Moore, with inspiration from the writings of Barry Commoner[52]

Organizational development


MV Esperanza, a former fire-fighter owned by the Russian Navy, was relaunched by Greenpeace in 2002

Greenpeace evolved from a group of Canadian and American protesters into a less conservative group of environmentalists who were more reflective of the counterculture and hippie youth movements of the 1960s and 1970s.[53] The social and cultural background from which Greenpeace emerged heralded a period of de-conditioning away from old world antecedents and sought to develop new codes of social, environmental and political behavior.[54][55]

In the mid-1970s independent groups using the name Greenpeace started springing up world wide. By 1977 there were 15 to 20 Greenpeace groups around the world.[56] At the same time the Canadian Greenpeace office was heavily in debt. Disputes between offices over fund-raising and organizational direction split the global movement as the North American offices were reluctant to be under the authority of the Vancouver office and its president Patrick Moore.[56]

After the incidents of Moruroa, David McTaggart had moved to France to battle in court with the French state and helped to develop the cooperation of European Greenpeace groups.[29] David McTaggart lobbied the Canadian Greenpeace Foundation to accept a new structure which would bring the scattered Greenpeace offices under the auspices of a single global organization. The European Greenpeace paid the debt of the Canadian Greenpeace office and on October 14, 1979, Greenpeace International came into existence.[36][56] Under the new structure, the local offices would contribute a percentage of their income to the international organization, which would take responsibility for setting the overall direction of the movement with each regional office having one vote.[56] Some Greenpeace groups, namely London Greenpeace (dissolved in 2001) and the US-based Greenpeace Foundation (still operational) however decided to remain independent from Greenpeace International.[57][58]

Organizational structure

Governance


The governance and management structure of Greenpeace.

Greenpeace consists of Greenpeace International (officially Stichting Greenpeace Council) based in Amsterdam, Netherlands, and 28 regional offices operating in 45 countries.[59] The regional offices work largely autonomously under the supervision of Greenpeace International. The executive director of Greenpeace is elected by the board members of Greenpeace International. The current director of Greenpeace International is Kumi Naidoo and the current Chair of the Board is Brazilian Ana Toni.[60][61] Greenpeace has a staff of 2,400[62] and 15,000 volunteers globally.[1]

Each regional office is led by a regional executive director elected by the regional board of directors. The regional boards also appoint a trustee to The Greenpeace International Annual General Meeting, where the trustees elect or remove the board of directors of Greenpeace International. The role of the annual general meeting is also to discuss and decide the overall principles and strategically important issues for Greenpeace in collaboration with the trustees of regional offices and Greenpeace International board of directors.[63]

Funding

Greenpeace receives its funding from individual supporters and foundations.[5][6] Greenpeace screens all major donations in order to ensure it does not receive unwanted donations.[64] The organization does not accept money from governments, intergovernmental organizations, political parties or corporations in order to avoid their influence.[5][6][64] However, Greenpeace does receive money from the National Postcode Lottery, the biggest government-sponsored lottery in the Netherlands,[65] and several for profit companies like Ben & Jerry's partner with and indicate they donate a percentage of sales to Greenpeace campaigns.[66] Donations from foundations which are funded by political parties or receive most of their funding from governments or intergovernmental organizations are rejected. Foundation donations are also rejected if the foundations attach unreasonable conditions, restrictions or constraints on Greenpeace activities or if the donation would compromise the independence and aims of Greenpeace.[64] Since in the mid-1990s the number of supporters started to decrease, Greenpeace pioneered the use of face-to-face fundraising where fundraisers actively seek new supporters at public places, subscribing them for a monthly direct debit donation.[67][68] In 2008, most of the €202.5 million received by the organization was donated by about 2.6 million regular supporters, mainly from Europe.[62] In 2014, the annual revenue of Greenpeace was reported to be about €300 million (US$400 million) although they lost about €4 million (US$5 million) in currency speculation that year.[69]

In September 2003, Public Interest Watch (PIW) complained to the Internal Revenue Service that Greenpeace USA tax returns were inaccurate and in violation of the law.[70] The IRS conducted an extensive review and concluded in December 2005 that Greenpeace USA continued to qualify for its tax-exempt status. In March 2006 The Wall Street Journal reported that PIW's "federal tax filing, covering August 2003 to July 2004, stated that $120,000 of the $124,095 the group received in contributions during that period came from Exxon Mobil."[71] In 2013, after the IRS performed a follow-up audit, which again was clean, and, following claims of politically motivated IRS audits of groups affiliated with the Tea Party Movement, Greenpeace U.S. Executive Director Phil Radford called for a Congressional investigation into all politically motivated audits – including those allegedly targeting the Tea Party Movement, the NAACP, and Greenpeace.[72]

Summary of priorities and campaigns

On its official website, Greenpeace defines its mission as the following:
Greenpeace is an independent global campaigning organization that acts to change attitudes and behaviour, to protect and conserve the environment and to promote peace by:
  • Catalysing an energy revolution to address the number one threat facing our planet: climate change.
  • Defending our oceans by challenging wasteful and destructive fishing, and creating a global network of marine reserves.
  • Protecting the world's remaining ancient forests which are depended on by many animals, plants and people.
  • Working for disarmament and peace by reducing dependence on finite resources and calling for the elimination of all nuclear weapons.
  • Creating a toxin free future with safer alternatives to hazardous chemicals in today's products and manufacturing.
  • Campaigning for sustainable agriculture by encouraging socially and ecologically responsible farming practices.

Climate and energy

Greenpeace was one of the first parties to formulate a sustainable development scenario for climate change mitigation, which it did in 1993.[74] According to sociologists Marc Mormont and Christine Dasnoy, Greenpeace played a significant role in raising public awareness of global warming in the 1990s.[75] The organization has also focused on CFCs, because of both their global warming potential and their effect on the ozone layer. Greenpeace was one of the leading participants advocating early phase-out of ozone depleting substances in the Montreal Protocol.[17] In the early 1990s, Greenpeace developed a CFC-free refrigerator technology, "Greenfreeze" for mass production together with the refrigerator industry.[17] United Nations Environment Programme awarded Greenpeace for "outstanding contributions to the protection of the Earth's ozone layer" in 1997.[76] In 2011 two fifths of the world's total production of refrigerators were based on Greenfreeze technology, with over 600 million units in use.[17] [77] Moreover, Greenfreeze technology had been blocked in the U.S. by the EPA being lobbied by a coalition of chemical corporations including Du Pont until the 2011 decision which cited Ben & Jerry's and General Electric's interest beginning in 2008.[77][78][79][80] Currently Greenpeace considers global warming to be the greatest environmental problem facing the Earth.[73]
Greenpeace calls for global greenhouse gas emissions to peak in 2015 and to decrease as close to zero as possible by 2050. For this Greenpeace calls for the industrialized countries to cut their emissions at least 40% by 2020 (from 1990 levels) and to give substantial funding for developing countries to build a sustainable energy capacity, to adapt to the inevitable consequences of global warming, and to stop deforestation by 2020.[81] Together with EREC, Greenpeace has formulated a global energy scenario, "Energy [R]evolution", where 80% of the world's total energy is produced with renewables, and the emissions of the energy sector are decreased by over 80% of the 1990 levels by 2050.[82]

Using direct action, Greenpeace has protested several times against coal by occupying coal power plants and blocking coal shipments and mining operations, in places such as New Zealand,[83] Svalbard,[84] Australia,[85] and the United Kingdom.[86] Greenpeace is also critical of extracting petroleum from oil sands and has used direct action to block the oil sand operations at Athabasca, Canada.[87][88]

Kingsnorth court case

In October 2007, six Greenpeace protesters were arrested for breaking into the Kingsnorth power station, climbing the 200 metre smokestack, painting the name Gordon on the chimney, and causing an estimated £30,000 damage. At their subsequent trial they admitted trying to shut the station down, but argued that they were legally justified because they were trying to prevent climate change from causing greater damage to property elsewhere around the world. Evidence was heard from David Cameron's environment adviser Zac Goldsmith, climate scientist James E. Hansen and an Inuit leader from Greenland, all saying that climate change was already seriously affecting life around the world.
The six activists were acquitted. It was the first case where preventing property damage caused by climate change has been used as part of a "lawful excuse" defense in court.[89] Both The Daily Telegraph and The Guardian described the acquittal as embarrassment to the Brown Ministry.[90][91] In December 2008 The New York Times listed the acquittal in its annual list of the most influential ideas of the year.[92]

"Go Beyond Oil"

As part of their stance on renewable energy commercialisation, Greenpeace have launched the "Go Beyond Oil" campaign.[93] The campaign is focused on slowing, and eventually ending, the world's consumption of oil; with activist activities taking place against companies that pursue oil drilling as a venture. Much of the activities of the "Go Beyond Oil" campaign have been focused on drilling for oil in the Arctic and areas affected by the Deepwater Horizon disaster. The activities of Greenpeace in the arctic have mainly involved the Edinburgh-based oil and gas exploration company, Cairn Energy; and range from protests at the Cairn Energy's headquarters[94] to scaling their oil rigs in an attempt to halt the drilling process.[95]

The "Go Beyond Oil" campaign also involves applying political pressure on the governments who allow oil exploration in their territories; with the group stating that one of the key aims of the "Go Beyond Oil" campaign is to "work to expose the lengths the oil industry is willing to go to squeeze the last barrels out of the ground and put pressure on industry and governments to move beyond oil."[93]

Nuclear power

Greenpeace views nuclear power as a relatively minor industry with major problems, such as environmental damage and risks from uranium mining, nuclear weapons proliferation, and unresolved questions concerning nuclear waste.[96] The organization argues that the potential of nuclear power to mitigate global warming is marginal, referring to the IEA energy scenario where an increase in world's nuclear capacity from 2608 TWh in 2007 to 9857 TWh by 2050 would cut global greenhouse gas emissions less than 5% and require 32 nuclear reactor units of 1000MW capacity built per year until 2050. According to Greenpeace the slow construction times, construction delays, and hidden costs, all limit the mitigation potential of nuclear power. This makes the IEA scenario technically and financially unrealistic. They also argue that binding massive amounts of investments on nuclear energy would take funding away from more effective solutions.[82] Greenpeace views the construction of Olkiluoto 3 nuclear power plant in Finland as an example of the problems on building new nuclear power.[97]

Anti-nuclear advertisement

In 1994, Greenpeace published an anti-nuclear newspaper advert which included a claim that nuclear facilities Sellafield would kill 2,000 people in the next 10 years, and an image of a hydrocephalus-affected child said to be a victim of nuclear weapons testing in Kazakhstan. Advertising Standards Authority viewed the claim concerning Sellafield unsubstantiated, and ASA did not accept that the child's condition was caused by radiation. This resulted in banning of the advert. Greenpeace did not admit fault, stating that a Kazakhstan doctor had said that the child's condition was due to nuclear testing. Adam Woolf from Greenpeace also stated that, "fifty years ago there were many experts who would be lined up and swear there was no link between smoking and bad health."[98] The UN has estimated that the nuclear weapon tests in Kazakhstan caused about 100,000 people to suffer over three generations.[99]

EDF spying conviction and appeal

In 2011, a French court fined Électricité de France (EDF) €1.5m and jailed two senior employees for spying on Greenpeace, including hacking into Greenpeace's computer systems. Greenpeace was awarded €500,000 in damages.[100] Although EDF claimed that a security firm had only been employed to monitor Greenpeace, the court disagreed, jailing the head and deputy head of EDF's nuclear security operation for three years each. EDF appealed the conviction, the company was cleared of conspiracy to spy on Greenpeace and the fine was cancelled.[101] Two employees of the security firm, Kargus, run by a former member of France's secret services, received sentences of three and two years respectively.[102]

Heads of State, 2020 Copenhagen Campaign

Tcktcktck partnered with Greenpeace for a billboard campaign in Copenhagen International airport. The adverts are photographs calling on world leaders to secure a fair, ambitious and binding deal at the Copenhagen Climate Summit. The billboards are future trajectories of the world in 2020, the world leaders with tired, hopeless looks on their faces with their lips closed to swallow unsaid words. They show President Obama and other world leaders as they might look 11 years from now, with the headline, "I'm sorry. We could have stopped catastrophic climate change ... We didn't." [103]

This billboard demonstrates how Greenpeace exploited world leaders, leading to public relations discourse of climate change

Forest campaign

Greenpeace aims at protecting intact primary forests from deforestation and degradation with the target of zero deforestation by 2020. Greenpeace has accused several corporations, such as Unilever,[104] Nike,[105] KFC, KitKat and McDonald's[106] of having links to the deforestation of the tropical rainforests, resulting in policy changes in several of the companies under criticism.[107][108][109] Greenpeace, together with other environmental NGOs, also campaigned for ten years for the EU to ban import of illegal timber. The EU decided to ban illegal timber on July 2010.[110] As deforestation contributes to global warming, Greenpeace has demanded that REDD (Reduced Emission from Deforestation and Forest Degradation) should be included in the climate treaty following the Kyoto treaty.[111]

Another Greenpeace movement concerning the rain forests is discouraging palm oil industries.[112] The movement has been the most active in Indonesia where already 6 million hectares are used for palm oil plantation and has plans for another 4 million hectares by 2015. Acknowledging that mass production of palm oil may be disastrous on biodiversity of forests, Greenpeace is actively campaigning against the production, urging the industries and the government to turn to other forms of energy resources. One of the positive results of the campaign was GAR(Golden Agri-Resources),[113] the world's second largest palm oil production company, deciding to commit itself to forest conservation. The company signed an agreement which prevents them from developing plantations in areas where large amounts of carbon are locked up.

Removal of an ancient tree

In June 1995, Greenpeace took a trunk of a tree from the forests of the proposed national park of Koitajoki[114] in Ilomantsi, Finland and put it on display at exhibitions held in Austria and Germany. Greenpeace said in a press conference that the tree was originally from a logged area in the ancient forest which was supposed to be protected. Metsähallitus accused Greenpeace of theft and said that the tree was from a normal forest and had been left standing because of its old age. Metsähallitus also said that the tree had actually crashed over a road during a storm.[115] The incident received publicity in Finland, for example in the large newspapers Helsingin Sanomat and Ilta-Sanomat.[116]
Greenpeace replied that the tree had fallen down because the protective forest around it had been clearcut, and that they wanted to highlight the fate of old forests in general, not the fate of one particular tree.[117] Greenpeace also highlighted that Metsähallitus admitted the value of the forest afterwards as Metsähallitus currently refers to Koitajoki as a distinctive area because of its old growth forests.[118][119]

'Tokyo Two'

In 2008, two Greenpeace anti-whaling activists, Junichi Sato and Toru Suzuki, stole a case of whale meat from a delivery depot in Aomori prefecture, Japan. Their intention was to expose what they considered embezzlement of the meat collected during whale hunts. After a brief investigation of their allegations was ended, Sato and Suzuki were arrested and charged with theft and trespass.[120]  
Amnesty International said that the arrests and following raids on Greenpeace Japan office and homes of five of Greenpeace staff members were aimed at intimidating activists and non-governmental organizations.[121] They were convicted of theft and trespass in September 2010 by the Aomori district court.

Genetically modified organisms (GMOs)

Greenpeace has also supported the rejection of GM food from the US in famine-stricken Zambia as long as supplies of non-genetically engineered grain exist, stating that the US "should follow in the European Union's footsteps and allow aid recipients to choose their food aid, buying it locally if they wish. This practise can stimulate developing economies and creates more robust food security", adding that, "if Africans truly have no other alternative, the controversial GE maize should be milled so it can't be planted. It was this condition that allowed Zambia's neighbours Zimbabwe and Malawi to accept it."[122] After Zambia banned all GM food aid, the former agricultural minister of Zambia criticized, "how the various international NGOs that have spoken approvingly of the government's action will square the body count with their various consciences."[123] Concerning the decision of Zambia, Greenpeace has stated that, "it was obvious to us that if no non-GM aid was being offered then they should absolutely accept GM food aid. But the Zambian government decided to refuse the GM food. We offered our opinion to the Zambian government and, as many governments do, they disregarded our advice."[124]

Greenpeace on golden rice

Greenpeace opposes the planned use of golden rice, a variety of Oryza sativa rice produced through genetic engineering to biosynthesize beta-carotene, a precursor of pro-vitamin A in the edible parts of rice. The addition of beta-carotene to the rice is seen as preventative to loss of sight in poverty stricken countries where golden rice is intended for distribution. According to Greenpeace, golden rice has not managed to do anything about malnutrition for 10 years during which alternative methods are already tackling malnutrition. The alternative proposed by Greenpeace is to discourage mono-cropping and to increase production of crops which are naturally nutrient-rich (containing other nutrients not found in golden rice in addition to beta-carotene). Greenpeace argues that resources should be spent on programs that are already working and helping to relieve malnutrition.[125] The Golden Rice Project acknowledges that, "While the most desirable option is a varied and sufficient diet, this goal is not always achievable, at least not in the short term."[126]

The renewal of these concerns coincided with the publication of a paper in the journal Nature about a version of golden rice with much higher levels of beta carotene.[127] This "golden rice 2" was developed and patented by Syngenta, which provoked Greenpeace to renew its allegation that the project is driven by profit motives.[128] C.S. Prakash, director of the Center for Plant Biotechnology Research at Tuskegee University and president of the AgBioWorld Foundation, expressed the opinion that "[c]ritics condemned biotechnology as something that is purely for profit, that is being pursued only in the West, and with no benefits to the consumer. Golden Rice proves them wrong, so they need to discredit it any way they can."[129]

Although Greenpeace had stated that efficiency was its primary concern, as early as 2001,[130] statements from March and April 2005 also continued to express concern over human health and environmental safety.[131][132] Greenpeace has opposed releasing golden rice to fields as opposed to farming in greenhouses, which according to golden rice developer Ingo Potrykus, limits the amount of material needed for human safety testing.[133]

Patrick Moore says that the very reason for malnutrition is that the families cannot afford much else than rice.[134] According to Adrian Dubock, golden rice would not cost more than ordinary rice and now vitamin A deficiency is the main reason for blindness and responsible for 28% of child mortality.[135] Now vitamin A deficiency blinds and kills at least hundreds of thousands of children every year.[136]

On July 14, 2011, Greenpeace paid the reparations when its members broke into the premises of an Australian scientific research organization CSIRO and destroyed a genetically modified wheat plot that would have a lower glycemic index and hence benefit people who are diabetic. The sentencing judge, Justice Hilary Penfold, accused Greenpeace of cynically using junior members to avoid custodial sentences, while the offenders were given 9 month suspended sentences.[24][25][26]

On August 8, 2013, an experimental plot of golden rice by International Rice Research Institute in the Philippines was uprooted.[137][138] Mark Lynas, former anti-GMO activist, reported that the action was in reality carried out by a group of 50 anti-GMO activists.[139] Greenpeace representatives defended the vandals.[136]

Jim Peacock (former chief scientist of Australia and president of the Australian Academy of Science) accused Greenpeace of being anti-science and spreading misinformation immorally.[140]

Toxic waste

In July 2011, Greenpeace released its Dirty Laundry report accusing some of the world's top fashion and sportswear brands of releasing toxic waste into China's rivers.[141] The report profiles the problem of water pollution resulting from the release of toxic chemicals associated with the country's textile industry. Investigations focused on wastewater discharges from two facilities in China; one belonging to the Youngor Group located on the Yangtze River Delta and the other to Well Dyeing Factory Ltd. located on a tributary of the Pearl River Delta. Scientific analysis of samples from both facilities revealed the presence of hazardous and persistent hormone disruptor chemicals, including alkylphenols, perfluorinated compounds and perfluorooctane sulfonate.

The report goes on to assert that the Youngor Group and Well Dyeing Factory Ltd. - the two companies behind the facilities - have commercial relationships with a range of major clothing brands, including Abercrombie & Fitch, Adidas, Bauer Hockey, Calvin Klein, Converse, Cortefiel, H&M, Lacoste, Li Nang, Metersbonwe Group, Nike, Phillips-Van Heusen and Puma AG.

In 2013, Greenpeace launched the "Detox Fashion" campaign, which signed up some fashion brands to stop the discharge of toxic chemicals into rivers as a result of the production of their clothes.[142]

Save the Arctic

In continuity of the successful campaign to reach the Antarctic-Environmental Protocol, in 2012 and 2013 protests with "Save the Arctic" banners were started. To stop oil- and gas-drilling, industrial fishing and military operations in the Arctic region completely, a "global sanctuary in the high arctic" was demanded from the World leaders at the UN General Assembly: "We want them to pass a UN resolution expressing international concern for the Arctic." A resolution to protect the very vulnerable wildlife and ecosystem.[143] 30 Arctic Sunrise activists were arrested in the Pechora Sea, 19 September 2013, witnessing oil-drilling and protesting at the Gazprom platform Prirazlomnaya by the Russian Coast Guard.[144] Greenpeace members were originally charged with Piracy, then later downgraded to hooliganism, before being dropped altogether following the passage of an amnesty law by the Russian government.[145]
In July 2014, Greenpeace launched a global boycott campaign to persuade Lego to cease producing toys carrying the oil company Shell's logo in response to Shell's plans to drill for oil in the Arctic.[146] Lego's partnership with Shell dates back to the 1960s, although the LEGO company created a fictional oil company called Octan. Octan has appeared in countless sets, computer and console games, can be seen at Legoland parks, and is featured as the corporation headed by the villain President Business in The Lego Movie.[147]

There is a confliction over oil rigs in the Arctic Ocean between Norwegian Government and Greenpeace. On May 27, 2014, Esperanza, the ship of Greenpeace, which is environmental group opposed to drilling oil well in the Arctic area, took over Transocean Spitsbergen, oil rig of Statoil[148] (Norway's world-wide company which deals with energy sources) Statoil in the Barents Sea so that it cannot drill well. After that, the manager of Greenpeace Norway Norway Truls Gulowsen answered a phone interview, "Five protesters left the rig by helicopter last night and three returned to a nearby Greenpeace ship." [149] There were seven more protesters on the rig then, but Norwegian police could not remove them immediately because the rig was a flag-of-convenience ship registered in the Marshall Islands and regarded as a ship in the open sea as long as it did not begin drilling. On May 29, however, the seven activists from Greenpeace were peacefully captured by Norwegian police on the rig at last, but soon after that, according to Reuters, all the activists were set free without any fine. On May 30, Norwegian Coast Guard finally towed away Esperanza, though in the morning Greenpeace submitted a plea on which more than 80,000 signatures to the Norwegian Environment Minister Tine Sundtoft in Oslo were written. Norwegian government and police reportedly allowed the coast guard to tow the Greenpeace ship.[150]

History

Not only in 2014, there has been the fight over oil rigs in the Arctic Ocean between Greenpeace and Statoil. Statoil has exploited over 100 oil wells in the Barents Sea and this has been blamed because it endangered Bear Island (Norway). On the other hand, Norwegian government has not permitted exploitation close to the ice-edge, for it is hard to get rid of oil on the ice.[151] In 2013, three activists of Greenpeace got on a Statoil's oil rig, wearing bear suits. According to a spokesman from Greenpeace Russia, they stayed on the rig for about three hours. The activists in bear suits "were escorted" to the shore lastly. Statoil reportedly did not intend to file a suit against them.[152]

Arguments

The argument of Norway Police

The Norwegian police stated that Statoil asked Greenpeace to stop preventing it's activities, but Greenpeace ignored the warning. The police has stated that Greenpeace's interference with the petroleum activities of Statoil - was the contrary to Norwegian law and ordered Greenpeace to leave the Barents Sea site.[153]

The argument of Greenpeace

Greenpeace had argued that Statoil's drilling plans posed a threat to Bear Island, an uninhabited wildlife sanctuary that is home to rare species, including polar bears, because an oil spill would be nearly impossible to clean up in the Arctic because of the harsh conditions. Greenpeace Regards the petroleum activities of Statoil as "illegal".[153]

The argument of Statoil

Statoil denies Greenpeace statement. According to The Maritime Executive (2014),[154] Statoil says "Statoil respects people's right to make a legal protest, and we feel it is important to have a democratic debate around the oil industry. We have established robust plans for the operation, and feel confident they can be carried out safely and without accidents."

Effects

Environmental effects

Greenpeace argues that because of Arctic oil drilling, "an oil spill could hurt vulnerable ecosystems".[149] It is because "the drilling project in the Hoop area of the Barents Sea is too close to the sea ice and to Bear Island 175 kilometers (110 miles) away".[154]

Economic effects

Statoil said delays to the start of drilling cost the company about $1.26 million per day. Statoil and the government of Norway is strongly related and this economic loss can do the government and the Norwegian people harm severely.[150]

Governmental effects

The government of Norway believes that to produce oil will give people a lot of energy, so it supports the act of Statoil.[153] However, Greenpeace never agrees with it, so the relationship of Norway and Greenpeace can get worse.

Problems

Statoil and Greenpeace indicate the problems of their opponents' activities in different point of view. Statoil argues that because of Greenpeace's obstruction to their oil drilling, it has to postpone the start of drilling so the company would make a loss of "7.5 million crowns ($1, 26 million) per day"[155](RIGZONE 2014) and it has no choice but to place a financial burden upon the society[154] (The Maritime Executive). On the other hand, according to Reuters, Greenpeace argues that Statoil's oil drilling do serious harm to a part of the Arctic Ocean and one island of the Barents Sea. It points the potential danger of oil spilling in the sea. It argues that Statoil's schemes for oil drilling have bad influence on the Arctic ice sheet and the island of Bjørnøya (Bear Island), according to the Wikipedia article Bear Island , which is located in west area of Barents Sea and a wildlife reserve, so nobody lives there. In the island, instead of human being, some kinds of rare animals (ex, polar bears) and plants inhabit. Given the hard situation in the Arctic Sea, once oil is spilled, anyone would be unable to recover the spilled oil. Regarding this Greenpeace's arguments, Statoil says "The probability of an oil spill happening is extremely low, …and we are operating in familiar waters." and "There are two factors that indicate an extremely low probability of oil reaching Bjørnøya. Firstly, there is a very low risk of an oil spill occurring at all, and secondly, there is an extremely low risk of any spillage reaching Bjørnøya." and tells that "The [oil] exploration will take place about 300 kilometres from the mainland and 170 kilometres from the island of Bjørnøya." (Statoil 2014).[156] The Norwegian government keeps on the side of large oil companies and turn down requests from environmental groups which are small scale.

Future

According to Reuters, in summer in 2014, Statoil is going to start drilling "three oil wells in the Apollo, Atlantis and Mercury prospects in the Hoop area, [which is] some 300 km away from the mainland [of Norway]". On the other hand, Greenpeace does and will do criticize the big oil company for it doing "green wash". Greenpeace argues that Statoil hide the truth that it is doing the risky oil drilling by holding "Lego League" with Lego and distracting people's attention to the company's project, and it also argues that Statoil has to alter its attitude toward environments[157] (Norway's News in English 2014).

Ships

Since Greenpeace was founded, seagoing ships have played a vital role in its campaigns. Now that the Rainbow Warrior III has been completed, the group has three ocean-going ships, the Esperanza, Arctic Sunrise and Rainbow Warrior III.[158]

First Rainbow Warrior

In 1978, Greenpeace launched the original Rainbow Warrior, a 40-metre (130 ft), former fishing trawler named for the book Warriors of the Rainbow, which inspired early activist Robert Hunter on the first voyage to Amchitka. Greenpeace purchased the Rainbow Warrior (originally launched as the Sir William Hardy in 1955) at a cost of £40,000. Volunteers restored and refitted it over a period of four months. First deployed to disrupt the hunt of the Icelandic whaling fleet, the Rainbow Warrior would quickly become a mainstay of Greenpeace campaigns. Between 1978 and 1985, crew members also engaged in direct action against the ocean-dumping of toxic and radioactive waste, the Grey Seal hunt in Orkney and nuclear testing in the Pacific. In May 1985, the vessel was instrumental for 'Operation Exodus', the evacuation of about 300 Rongelap Atoll islanders whose home had been contaminated with nuclear fallout from a US nuclear test two decades ago which had never been cleaned up and was still having severe health effects on the locals.[159]

Later in 1985 the Rainbow Warrior was to lead a flotilla of protest vessels into the waters surrounding Moruroa atoll, site of French nuclear testing. The sinking of the Rainbow Warrior occurred when the French government secretly bombed the ship in Auckland harbour on orders from François Mitterrand himself. This killed Dutch freelance photographer Fernando Pereira, who thought it was safe to enter the boat to get his photographic material after a first small explosion, but drowned as a result of a second, larger explosion.[160] The attack was a public relations disaster for France after it was quickly exposed by the New Zealand police. The French Government in 1987 agreed to pay New Zealand compensation of NZ$13 million and formally apologised for the bombing. The French Government also paid 2.3 million compensation to the family of the photographer. Later, in 2001, when the Institute of Cetacean Research of Japan called Greenpeace "eco-terrorists", Gert Leipold, then Executive Director of Greenpeace, detested the claim, saying "calling non violent protest terrorism insults those who were injured or killed in the attacks of real terrorists, including Fernando Pereira, killed by State terrorism in the 1985 attack on the Rainbow Warrior".[161]

Second Rainbow Warrior[edit]


Greenpeace's second Rainbow Warrior ship arrives in Bali for the 2007 UN climate conference.

In 1989 Greenpeace commissioned a replacement vessel, also named the Rainbow Warrior (also referred as Rainbow Warrior II), which was retired from service on the 16th of August 2011 to be replaced by the third Rainbow Warrior. In 2005 the Rainbow Warrior II ran aground on and damaged the Tubbataha Reef in the Philippines while inspecting the reef for coral bleaching. Greenpeace was fined US$7,000 for damaging the reef and agreed to pay the fine saying they felt responsible for the damage, although Greenpeace stated that the Philippines government had given it outdated charts. The park manager of Tubbataha appreciated the quick action Greenpeace took to assess the damage to the reef.[162]

Other vessels

Along with the Rainbow Warriors, Greenpeace has had several other ships in its service: MV Sirius, MV Solo, MV Greenpeace, MV Arctic Sunrise and MV Esperanza, the last two being in service today.

Reactions and responses to Greenpeace activities

Lawsuits have been filed against Greenpeace for lost profits,[163] reputation damage[164] and "sailormongering".[165] In 2004 it was revealed that the Australian government was willing to offer a subsidy to Southern Pacific Petroleum on the condition that the oil company would take legal action against Greenpeace, which had campaigned against the Stuart Oil Shale Project.[166]

Some corporations, such as Royal Dutch Shell, BP and Électricité de France have reacted to Greenpeace campaigns by spying on Greenpeace activities and infiltrating Greenpeace offices.[167][168] Greenpeace activists have also been targets of phone tapping, death threats, violence[36] and even state terrorism in the case of the bombing of the Rainbow Warrior.[169][170]

Criticism

Canadian ecologist Patrick Moore, an early Greenpeace member, left the organization in 1986 when it, according to Moore, decided to support a universal ban on chlorine[171] in drinking water.[20] 
Moore has argued that Greenpeace today is motivated by politics rather than science and that none of his "fellow directors had any formal science education".[20] Bruce Cox, Director of Greenpeace Canada, responded that Greenpeace has never demanded a universal chlorine ban and that Greenpeace does not oppose use of chlorine in drinking water or in pharmaceutical uses, adding that "Mr. Moore is alone in his recollection of a fight over chlorine and/or use of science as his reason for leaving Greenpeace."[172] Paul Watson, an early member of Greenpeace has said that Moore "uses his status as a so-called co-founder of Greenpeace to give credibility to his accusations. I am also a co-founder of Greenpeace and I have known Patrick Moore for 35 years.[...] Moore makes accusations that have no basis in fact".[173] More recently Moore has been particularly critical of Greenpeace's stance on golden rice, an issue where Moore has been joined by other environmentalists such as Mark Lynas,[174] claiming that Greenpeace has "waged a campaign of misinformation, trashed the scientists who are working to bring Golden Rice to the people who need it, and supported the violent destruction of Golden Rice field trials."[175]
Patrick Moore also reversed his position on nuclear power in 1976,[176] first opposing it and now supporting it.[177][178][179] In Australian newspaper The Age, he writes "Greenpeace is wrong — we must consider nuclear power".[180] He argues that any realistic plan to reduce reliance on fossil fuels or greenhouse gas emissions need increased use of nuclear energy.[177] Phil Radford, Executive Director of Greenpeace US responded that nuclear energy is too risky, takes too long to build to address climate change, and claims that most countries, including the U.S., could shift to nearly 100% renewable energy while phasing out nuclear power by 2050.[181][182]

A French journalist under the pen name Olivier Vermont wrote in his book La Face cachée de Greenpeace ("The Hidden Face of Greenpeace") that he had joined Greenpeace France and had worked there as a secretary. According to Vermont he found misconduct, and continued to find it, from Amsterdam to the International office. Vermont said he found classified documents[183] according to which half of the organization's €180 million revenue was used for the organization's salaries and structure. He also accused Greenpeace of having unofficial agreements with polluting companies where the companies paid Greenpeace to keep them from attacking the company's image.[184] Animal protection magazine Animal People reported in March 1997 that Greenpeace France and Greenpeace International had sued Olivier Vermont and his publisher Albin Michel for issuing "defamatory statements, untruths, distortions of the facts and absurd allegations".[185]

Writing in Cosmos, journalist Wilson da Silva reacted to Greenpeace's destruction of a genetically modified wheat crop in Ginninderra as another sign that the organization has "lost its way" and had degenerated into a "sad, dogmatic, reactionary phalanx of anti-science zealots who care not for evidence, but for publicity".[186]

Press release blunder

In Philadelphia, in 2006, Greenpeace issued a press release that said "In the twenty years since the Chernobyl tragedy, the world's worst nuclear accident, there have been nearly [FILL IN ALARMIST AND ARMAGEDDONIST FACTOID HERE]". The final report warned of plane crashes and reactor meltdowns.[187] According to a Greenpeace spokesman, the memo was a joke that was accidentally released.[187]

Brent Spar Tanker

Research published in natural science journal Nature accused Greenpeace of not caring for facts, when it criticized the dumping of the Brent Spar tanker, and accused the group of exaggerating the volume of oil that was stored in the tanker.[188] Greenpeace had claimed that the tanker contained 5,500 tonnes of crude oil, when in fact it contained much less.[189]

Shell UK took three years to evaluate disposal option and concluded that the disposal of the tanker in the deep ocean was the "Best Practicable Environmental Option" (BPEO), an option which gained some support within the scientific community, as it was found by some to be of "negligible" environmental impact.[189] British government and Oslo and Paris Commissions (OSPAR) accepted the solution.[189]

The resulting campaign against Shell's proposals (including violence and boycotts in Germany) caused the company to cancel the operation and announce that it had failed in communicating its plans sufficiently to the public, admitting they had underestimated the strength of public opinion.[189]

In 1999 the Brent Spar container was decommissioned and the legs of the structure were found to contain cold-water coral species (Lophelia pertusa). As a result, proposals were made to keep the legs of such platforms on the sea bed in future, to serve as habitat.[189][190][191] Greenpeace opposed the proposals, citing the fact that the reefs formed by the coral are at risk, not the coral itself, and that such a move would not promote development of such reefs, and expose coral species to toxic substances found in oil.[192]

Pascal Husting commute

In 2013 reports noted that Pascal Husting, the director of Greenpeace International's "international programme" was commuting 250 miles via plane, despite Greenpeace's activism to reduce air travel due to carbon footprint.[193][194][195] Greenpeace has said "the growth in aviation is ruining our chances of stopping dangerous climate change".[196] After a "public uproar" Greenpeace announced that Husting would commute via train in the future.[197][198]

Nazca Lines

In December 2014, Greenpeace activists irreparably damaged the Nazca Lines in Peru while setting up a banner within the lines of one of the famed geoglyphs. The activists damaged an area around the hummingbird by grinding rocks into the sandy soil. Access to the area around the lines is strictly prohibited and [27][199] special shoes must be worn to avoid damaging the UN World Heritage site.
Greenpeace claimed the activists were "absolutely careful to protect the Nazca lines,"[200] but this is contradicted by video and photographs showing the activists wearing conventional shoes (not special protective shoes) while walking on the site.[201] Greenpeace has apologized to the Peruvian people,[202] but Loise Jamie Castillo, Peru's Vice Minister of Cultural Heritage called the apology "a joke", because Greenpeace refused to identify the vandals or accept responsibility.[203] Culture Minister Diana Alvarez-Calderon said Monday that evidence gathered during an investigation by the government will be used as part of a legal suit against Greenpeace. "The damage done is irreparable and the apologies offered by the environmental group aren't enough," she said at a news conference.[27]

Gravitation


From Wikipedia, the free encyclopedia

Hammer and feather drop: Apollo 15 astronaut David Scott on the Moon recreating Galileo's famous gravity experiment. (1.38 MB, ogg/Theora format).

Gravitation or gravity is a natural phenomenon by which all physical bodies attract each other. Gravity gives weight to physical objects and causes them to fall toward one another.

In modern physics, gravitation is most accurately described by the general theory of relativity (proposed by Einstein) which describes gravitation as a consequence of the curvature of spacetime. For most situations gravity is well approximated by Newton's law of universal gravitation, which postulates that the gravitational force of two bodies of mass is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

In pursuit of a theory of everything, the merging of general relativity and quantum mechanics (or quantum field theory) into a more general theory of quantum gravity has become an area of active research. It is hypothesised that the gravitational force is mediated by a massless spin-2 particle called the graviton, and that gravity would have separated from the electronuclear force during the grand unification epoch.

Gravity is the weakest of the four fundamental forces of nature. The gravitational force is approximately 10−38 times the strength of the strong force (i.e. gravity is 38 orders of magnitude weaker), 10−36 times the strength of the electromagnetic force, and 10−29 times the strength of the weak force. As a consequence, gravity has a negligible influence on the behavior of sub-atomic particles, and plays no role in determining the internal properties of everyday matter. On the other hand, gravity is the dominant force at the macroscopic scale, that is the cause of the formation, shape, and trajectory (orbit) of astronomical bodies, including those of asteroids, comets, planets, stars, and galaxies. It is responsible for causing the Earth and the other planets to orbit the Sun; for causing the Moon to orbit the Earth; for the formation of tides; for natural convection, by which fluid flow occurs under the influence of a density gradient and gravity; for heating the interiors of forming stars and planets to very high temperatures; for solar system, galaxy, stellar formation and evolution; and for various other phenomena observed on Earth and throughout the universe. This is the case for several reasons: gravity is the only force acting on all particles; it has an infinite range; it is always attractive and never repulsive; and it cannot be absorbed, transformed, or shielded against. Even though electromagnetism is far stronger than gravity, electromagnetism is not relevant to astronomical objects, since such bodies have an equal number of protons and electrons that cancel out (i.e., a net electric charge of zero).

History of gravitational theory

Scientific revolution

Modern work on gravitational theory began with the work of Galileo Galilei in the late 16th and early 17th centuries. In his famous (though possibly apocryphal[1]) experiment dropping balls from the Tower of Pisa, and later with careful measurements of balls rolling down inclines, Galileo showed that gravitation accelerates all objects at the same rate. This was a major departure from Aristotle's belief that heavier objects accelerate faster.[2] Galileo postulated air resistance as the reason that lighter objects may fall slower in an atmosphere. Galileo's work set the stage for the formulation of Newton's theory of gravity.

Newton's theory of gravitation

Sir Isaac Newton, an English physicist who lived from 1642 to 1727

In 1687, English mathematician Sir Isaac Newton published Principia, which hypothesizes the inverse-square law of universal gravitation. In his own words, "I deduced that the forces which keep the planets in their orbs must [be] reciprocally as the squares of their distances from the centers about which they revolve: and thereby compared the force requisite to keep the Moon in her Orb with the force of gravity at the surface of the Earth; and found them answer pretty nearly."[3] The equation is the following:

F = G \frac{m_1 m_2}{r^2}\

Where F is the force, m1 and m2 are the masses of the objects interacting, r is the distance between the centers of the masses and G is the gravitational constant.

Newton's theory enjoyed its greatest success when it was used to predict the existence of Neptune based on motions of Uranus that could not be accounted for by the actions of the other planets.
Calculations by both John Couch Adams and Urbain Le Verrier predicted the general position of the planet, and Le Verrier's calculations are what led Johann Gottfried Galle to the discovery of Neptune.

A discrepancy in Mercury's orbit pointed out flaws in Newton's theory. By the end of the 19th century, it was known that its orbit showed slight perturbations that could not be accounted for entirely under Newton's theory, but all searches for another perturbing body (such as a planet orbiting the Sun even closer than Mercury) had been fruitless. The issue was resolved in 1915 by Albert Einstein's new theory of general relativity, which accounted for the small discrepancy in Mercury's orbit.

Although Newton's theory has been superseded, most modern non-relativistic gravitational calculations are still made using Newton's theory because it is a much simpler theory to work with than general relativity, and gives sufficiently accurate results for most applications involving sufficiently small masses, speeds and energies.

Equivalence principle

The equivalence principle, explored by a succession of researchers including Galileo, Loránd Eötvös, and Einstein, expresses the idea that all objects fall in the same way. The simplest way to test the weak equivalence principle is to drop two objects of different masses or compositions in a vacuum and see whether they hit the ground at the same time. Such experiments demonstrate that all objects fall at the same rate when friction (including air resistance) is negligible. More sophisticated tests use a torsion balance of a type invented by Eötvös. Satellite experiments, for example STEP, are planned for more accurate experiments in space.[4]

Formulations of the equivalence principle include:
  • The weak equivalence principle: The trajectory of a point mass in a gravitational field depends only on its initial position and velocity, and is independent of its composition.[5]
  • The Einsteinian equivalence principle: The outcome of any local non-gravitational experiment in a freely falling laboratory is independent of the velocity of the laboratory and its location in spacetime.[6]
  • The strong equivalence principle requiring both of the above.

General relativity

Two-dimensional analogy of spacetime distortion generated by the mass of an object. Matter changes the geometry of spacetime, this (curved) geometry being interpreted as gravity. White lines do not represent the curvature of space but instead represent the coordinate system imposed on the curved spacetime, which would be rectilinear in a flat spacetime.

In general relativity, the effects of gravitation are ascribed to spacetime curvature instead of a force. The starting point for general relativity is the equivalence principle, which equates free fall with inertial motion and describes free-falling inertial objects as being accelerated relative to non-inertial observers on the ground.[7][8] In Newtonian physics, however, no such acceleration can occur unless at least one of the objects is being operated on by a force.

Einstein proposed that spacetime is curved by matter, and that free-falling objects are moving along locally straight paths in curved spacetime. These straight paths are called geodesics. Like Newton's first law of motion, Einstein's theory states that if a force is applied on an object, it would deviate from a geodesic. For instance, we are no longer following geodesics while standing because the mechanical resistance of the Earth exerts an upward force on us, and we are non-inertial on the ground as a result. This explains why moving along the geodesics in spacetime is considered inertial.

Einstein discovered the field equations of general relativity, which relate the presence of matter and the curvature of spacetime and are named after him. The Einstein field equations are a set of 10 simultaneous, non-linear, differential equations. The solutions of the field equations are the components of the metric tensor of spacetime. A metric tensor describes a geometry of spacetime. The geodesic paths for a spacetime are calculated from the metric tensor.

Notable solutions of the Einstein field equations include:
The tests of general relativity included the following:[9]
  • General relativity accounts for the anomalous perihelion precession of Mercury.[10]
  • The prediction that time runs slower at lower potentials has been confirmed by the Pound–Rebka experiment, the Hafele–Keating experiment, and the GPS.
  • The prediction of the deflection of light was first confirmed by Arthur Stanley Eddington from his observations during the Solar eclipse of May 29, 1919.[11][12] Eddington measured starlight deflections twice those predicted by Newtonian corpuscular theory, in accordance with the predictions of general relativity. However, his interpretation of the results was later disputed.[13] More recent tests using radio interferometric measurements of quasars passing behind the Sun have more accurately and consistently confirmed the deflection of light to the degree predicted by general relativity.[14] See also gravitational lens.
  • The time delay of light passing close to a massive object was first identified by Irwin I. Shapiro in 1964 in interplanetary spacecraft signals.
  • Gravitational radiation has been indirectly confirmed through studies of binary pulsars.
  • Alexander Friedmann in 1922 found that Einstein equations have non-stationary solutions (even in the presence of the cosmological constant). In 1927 Georges Lemaître showed that static solutions of the Einstein equations, which are possible in the presence of the cosmological constant, are unstable, and therefore the static universe envisioned by Einstein could not exist. Later, in 1931, Einstein himself agreed with the results of Friedmann and Lemaître. Thus general relativity predicted that the Universe had to be non-static—it had to either expand or contract. The expansion of the universe discovered by Edwin Hubble in 1929 confirmed this prediction.[15]
  • The theory's prediction of frame dragging was consistent with the recent Gravity Probe B results.[16]
  • General relativity predicts that light should lose its energy when travelling away from the massive bodies. The group of Radek Wojtak of the Niels Bohr Institute at the University of Copenhagen collected data from 8000 galaxy clusters and found that the light coming from the cluster centers tended to be red-shifted compared to the cluster edges, confirming the energy loss due to gravity.[17]

Gravity and quantum mechanics

In the decades after the discovery of general relativity it was realized that general relativity is incompatible with quantum mechanics.[18] It is possible to describe gravity in the framework of quantum field theory like the other fundamental forces, such that the attractive force of gravity arises due to exchange of virtual gravitons, in the same way as the electromagnetic force arises from exchange of virtual photons.[19][20] This reproduces general relativity in the classical limit. However, this approach fails at short distances of the order of the Planck length,[18] where a more complete theory of quantum gravity (or a new approach to quantum mechanics) is required.

Specifics

Earth's gravity

Every planetary body (including the Earth) is surrounded by its own gravitational field, which exerts an attractive force on all objects. Assuming a spherically symmetrical planet, the strength of this field at any given point is proportional to the planetary body's mass and inversely proportional to the square of the distance from the center of the body.
The strength of the gravitational field is numerically equal to the acceleration of objects under its influence, and its value at the Earth's surface, denoted g, is expressed below as the standard average. According to the International Bureau of Weights and Measures, under the International System of Units (SI), the Earth's standard acceleration due to gravity is:

g = 9.80665 m/s2 (32.1740 ft/s2).[21][22]

This means that, ignoring air resistance, an object falling freely near the Earth's surface increases its velocity by 9.80665 m/s (32.1740 ft/s or 22 mph) for each second of its descent. Thus, an object starting from rest will attain a velocity of 9.80665 m/s (32.1740 ft/s) after one second, approximately 19.62 m/s (64.4 ft/s) after two seconds, and so on, adding 9.80665 m/s (32.1740 ft/s) to each resulting velocity. Also, again ignoring air resistance, any and all objects, when dropped from the same height, will hit the ground at the same time. It is relevant to note that Earth's gravity doesn't have the exact same value in all regions. There are slight variations in different parts of the globe due to latitude, surface features such as mountains and ridges, and perhaps unusually high or low sub-surface densities.[23]

If an object with comparable mass to that of the Earth were to fall towards it, then the corresponding acceleration of the Earth would be observable.

According to Newton's 3rd Law, the Earth itself experiences a force equal in magnitude and opposite in direction to that which it exerts on a falling object. This means that the Earth also accelerates towards the object until they collide. Because the mass of the Earth is huge, however, the acceleration imparted to the Earth by this opposite force is negligible in comparison to the object's. If the object doesn't bounce after it has collided with the Earth, each of them then exerts a repulsive contact force on the other which effectively balances the attractive force of gravity and prevents further acceleration.

The force of gravity on Earth is the resultant (vector sum) of two forces: (a) The gravitational attraction in accordance with Newton's universal law of gravitation, and (b) the centrifugal force, which results from the choice of an earthbound, rotating frame of reference. At the equator, the force of gravity is the weakest due to the centrifugal force caused by the Earth's rotation. The force of gravity varies with latitude and increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles.

The standard value of 9.80665 m/s2 is the one originally adopted by the International Committee on Weights and Measures in 1901 for 45° latitude, even though it has been shown to be too high by about five parts in ten thousand.[24] This value has persisted in meteorology and in some standard atmospheres as the value for 45° latitude even though it applies more precisely to latitude of 45°32'33".[25]

Equations for a falling body near the surface of the Earth


Ball falling freely under gravity. See text for description.

Under an assumption of constant gravity, Newton's law of universal gravitation simplifies to F = mg, where m is the mass of the body and g is a constant vector with an average magnitude of 9.81 m/s2.
The acceleration due to gravity is equal to this g. An initially stationary object which is allowed to fall freely under gravity drops a distance which is proportional to the square of the elapsed time. The image on the right, spanning half a second, was captured with a stroboscopic flash at 20 flashes per second. During the first 120 of a second the ball drops one unit of distance (here, a unit is about 12 mm); by 220 it has dropped at total of 4 units; by 320, 9 units and so on.

Under the same constant gravity assumptions, the potential energy, Ep, of a body at height h is given by Ep = mgh (or Ep = Wh, with W meaning weight). This expression is valid only over small distances h from the surface of the Earth. Similarly, the expression h = \tfrac{v^2}{2g} for the maximum height reached by a vertically projected body with initial velocity v is useful for small heights and small initial velocities only.

Gravity and astronomy

The discovery and application of Newton's law of gravity accounts for the detailed information we have about the planets in our solar system, the mass of the Sun, the distance to stars, quasars and even the theory of dark matter. Although we have not traveled to all the planets nor to the Sun, we know their masses. These masses are obtained by applying the laws of gravity to the measured characteristics of the orbit. In space an object maintains its orbit because of the force of gravity acting upon it. Planets orbit stars, stars orbit Galactic Centers, galaxies orbit a center of mass in clusters, and clusters orbit in superclusters. The force of gravity exerted on one object by another is directly proportional to the product of those objects' masses and inversely proportional to the square of the distance between them.

Gravitational radiation

In general relativity, gravitational radiation is generated in situations where the curvature of spacetime is oscillating, such as is the case with co-orbiting objects. The gravitational radiation emitted by the Solar System is far too small to measure. However, gravitational radiation has been indirectly observed as an energy loss over time in binary pulsar systems such as PSR B1913+16. It is believed that neutron star mergers and black hole formation may create detectable amounts of gravitational radiation. Gravitational radiation observatories such as the Laser Interferometer Gravitational Wave Observatory (LIGO) have been created to study the problem. No confirmed detections have been made of this hypothetical radiation.

Speed of gravity

In December 2012, a research team in China announced that it had produced measurements of the phase lag of Earth tides during full and new moons which seem to prove that the speed of gravity is equal to the speed of light.[26] It means that if the Sun suddenly disappeared, the Earth would keep orbiting it normally for 8 minutes, which is the time light takes to travel that distance. The team's findings were released in the Chinese Science Bulletin in February 2013.[27]

Anomalies and discrepancies

There are some observations that are not adequately accounted for, which may point to the need for better theories of gravity or perhaps be explained in other ways.

Rotation curve of a typical spiral galaxy: predicted (A) and observed (B). The discrepancy between the curves is attributed to dark matter.
  • Accelerating expansion: The metric expansion of space seems to be speeding up. Dark energy has been proposed to explain this. A recent alternative explanation is that the geometry of space is not homogeneous (due to clusters of galaxies) and that when the data are reinterpreted to take this into account, the expansion is not speeding up after all,[28] however this conclusion is disputed.[29]
  • Extra energetic photons: Photons travelling through galaxy clusters should gain energy and then lose it again on the way out. The accelerating expansion of the universe should stop the photons returning all the energy, but even taking this into account photons from the cosmic microwave background radiation gain twice as much energy as expected. This may indicate that gravity falls off faster than inverse-squared at certain distance scales.[30]
  • Extra massive hydrogen clouds: The spectral lines of the Lyman-alpha forest suggest that hydrogen clouds are more clumped together at certain scales than expected and, like dark flow, may indicate that gravity falls off slower than inverse-squared at certain distance scales.[30]

Feds May Finally Ditch Cholesterol Warning

Eggs for everybody!

After years of telling Americans that high-cholesterol foods would kill them, the federal government may ease up on warnings about this much-maligned nutrient. The U.S. Dietary Guidelines Advisory Committee will no longer list cholesterol among its "nutrients of concern," according to The Washington Post.

The committee is in the midst of updating federal dietary guidelines for 2015; the last update was in 2010. These guidelines are used to set school lunch standards and food labeling requirements and inform all sorts of government dietary advice.

The move reflects updated scientific thinking on cholesterol. While high cholesterol levels in the blood can still be a bad health indicator, scientists no longer view high blood cholesterol as a direct result of eating a cholesterol-rich diet, at least not for most people. Genetics may make some individuals more vulnerable to cholesterol in food, but scientists estimate this group only includes about 25 percent of the population.

Cholesterol is the latest in a long line of dietary demons pursued vigorosly by public-health officials only to be redeemed as nutrition science advances. One of the reasons trans fats found their way into large parts of the U.S. food supply was the government's campaign against products made with lard, prompting foodmakers to instead switch to partially-hydrogenated vegetable oils. These oils turned out to be high in the types of trans fats we now know are more dangerous than animal fats. The government also urged individuals to stop cooking with animal fats and instead use vegetable oils such as corn and soybean oil—both loaded with inflammation-spiking omega-6 fatty acids, which have been much more detrimental to American health than eating butter.

Government guidelines for optimal eating may have similarly screwed Americans over when it comes to fats in general. For years, health officials championed low-fat (and low-cholesterol) diets as optimal, pushing many to try and avoid fat in food as much as possible. But there are tons of different kinds of dietary fats, and a lot of them—particularly polyunsaturated fats of the variety found in fish, nuts, and grass-fed beef—are not just okay but incredibly beneficial for human health. Dietary fat is also necessary to help humans absorb other important nutrients, so a vegetable-filled, vitamin-rich salad actually becomes more nutritious if you add a little olive oil or egg.

Even the story behind saturated fat, characterized for decades as having no redeeming nutritional value, is a lot more complicated than scientists previously thought. A new study published in the journal Open Heart concluded that U.S. and U.K. dietary guidelines condemning saturated fat "should not have been introduced." Research has shown some types of saturated fatty acids are terrible for human health, while others are neutral or even good. As dietary science advances, more and more of this sort of nutritional nuance become apparent, making one-size-fits-all advice of the kind supplied by federal dietary guidelines seem all the more outdated.
