Conservation movement

From Wikipedia, the free encyclopedia

The conservation movement, also known as nature conservation, is a political, environmental, and social movement that seeks to manage and protect natural resources, including animal, fungus, and plant species as well as their habitat for the future. Conservationists are concerned with leaving the environment in a better state than the condition they found it in. Evidence-based conservation seeks to use high quality scientific evidence to make conservation efforts more effective.

The early conservation movement evolved out of necessity to maintain natural resources such as fisheries, wildlife management, water, soil, as well as conservation and sustainable forestry. The contemporary conservation movement has broadened from the early movement's emphasis on use of sustainable yield of natural resources and preservation of wilderness areas to include preservation of biodiversity. Some say the conservation movement is part of the broader and more far-reaching environmental movement, while others argue that they differ both in ideology and practice. Conservation is seen as differing from environmentalism and it is generally a conservative school of thought which aims to preserve natural resources expressly for their continued sustainable use by humans.

History

Early history

Sylva, or A Discourse of Forest-Trees and the Propagation of Timber in His Majesty's Dominions, title page of the first edition (1664)

The conservation movement can be traced back to John Evelyn's work Sylva, presented as a paper to the Royal Society in 1662. Published as a book two years later, it was one of the most highly influential texts on forestry ever published. Timbre resources in England were becoming dangerously depleted at the time, and Evelyn advocated the importance of conserving the forests by managing the rate of depletion and ensuring that the cut down trees get replenished.

The field developed during the 18th century, especially in Prussia and France where scientific forestry methods were developed. These methods were first applied rigorously in British India from the early 19th century. The government was interested in the use of forest produce and began managing the forests with measures to reduce the risk of wildfire in order to protect the "household" of nature, as it was then termed. This early ecological idea was in order to preserve the growth of delicate teak trees, which was an important resource for the Royal Navy.

Concerns over teak depletion were raised as early as 1799 and 1805 when the Navy was undergoing a massive expansion during the Napoleonic Wars; this pressure led to the first formal conservation Act, which prohibited the felling of small teak trees. The first forestry officer was appointed in 1806 to regulate and preserve the trees necessary for shipbuilding.

This promising start received a setback in the 1820s and 30s, when laissez-faire economics and complaints from private landowners brought these early conservation attempts to an end.

In 1837, American poet George Pope Morris published "Woodman, Spare that Tree!", a Romantic poem urging a lumberjack to avoid an oak tree that has sentimental value. The poem was set to music later that year by Henry Russell. Lines from the song have been quoted by environmentalists.

Origins of the modern conservation movement

Conservation was revived in the mid-19th century, with the first practical application of scientific conservation principles to the forests of India. The conservation ethic that began to evolve included three core principles: that human activity damaged the environment, that there was a civic duty to maintain the environment for future generations, and that scientific, empirically based methods should be applied to ensure this duty was carried out. Sir James Ranald Martin was prominent in promoting this ideology, publishing many medico-topographical reports that demonstrated the scale of damage wrought through large-scale deforestation and desiccation, and lobbying extensively for the institutionalization of forest conservation activities in British India through the establishment of Forest Departments. Edward Percy Stebbing warned of desertification of India. The Madras Board of Revenue started local conservation efforts in 1842, headed by Alexander Gibson, a professional botanist who systematically adopted a forest conservation program based on scientific principles. This was the first case of state management of forests in the world.

These local attempts gradually received more attention by the British government as the unregulated felling of trees continued unabated. In 1850, the British Association in Edinburgh formed a committee to study forest destruction at the behest of Dr. Hugh Cleghorn a pioneer in the nascent conservation movement.

He had become interested in forest conservation in Mysore in 1847 and gave several lectures at the Association on the failure of agriculture in India. These lectures influenced the government under Governor-General Lord Dalhousie to introduce the first permanent and large-scale forest conservation program in the world in 1855, a model that soon spread to other colonies, as well the United States. In the same year, Cleghorn organised the Madras Forest Department and in 1860 the department banned the use shifting cultivation. Cleghorn's 1861 manual, The forests and gardens of South India, became the definitive work on the subject and was widely used by forest assistants in the subcontinent. In 1861, the Forest Department extended its remit into the Punjab.

Sir Dietrich Brandis, a German forester, joined the British service in 1856 as superintendent of the teak forests of Pegu division in eastern Burma. During that time Burma's teak forests were controlled by militant Karen tribals. He introduced the "taungya" system, in which Karen villagers provided labor for clearing, planting and weeding teak plantations. After seven years in Burma, Brandis was appointed Inspector General of Forests in India, a position he served in for 20 years. He formulated new forest legislation and helped establish research and training institutions. The Imperial Forest School at Dehradun was founded by him.

Germans were prominent in the forestry administration of British India. As well as Brandis, Berthold Ribbentrop and Sir William P.D. Schlich brought new methods to Indian conservation, the latter becoming the Inspector-General in 1883 after Brandis stepped down. Schlich helped to establish the journal Indian Forester in 1874, and became the founding director of the first forestry school in England at Cooper's Hill in 1885. He authored the five-volume Manual of Forestry (1889–96) on silviculture, forest management, forest protection, and forest utilization, which became the standard and enduring textbook for forestry students.

Conservation in the United States

The American movement received its inspiration from 19th century works that exalted the inherent value of nature, quite apart from human usage. Author Henry David Thoreau (1817–1862) made key philosophical contributions that exalted nature. Thoreau was interested in peoples' relationship with nature and studied this by living close to nature in a simple life. He published his experiences in the book Walden, which argued that people should become intimately close with nature. The ideas of Sir Brandis, Sir William P.D. Schlich and Carl A. Schenck were also very influential—Gifford Pinchot, the first chief of the USDA Forest Service, relied heavily upon Brandis' advice for introducing professional forest management in the U.S. and on how to structure the Forest Service.

Both conservationists and preservationists appeared in political debates during the Progressive Era (the 1890s–early 1920s). There were three main positions.

  • Laissez-faire: The laissez-faire position held that owners of private property—including lumber and mining companies, should be allowed to do anything they wished on their properties.
  • Conservationists: The conservationists, led by future President Theodore Roosevelt and his close ally George Bird Grinnell, were motivated by the wanton waste that was taking place at the hand of market forces, including logging and hunting. This practice resulted in placing a large number of North American game species on the edge of extinction. Roosevelt recognized that the laissez-faire approach of the U.S. Government was too wasteful and inefficient. In any case, they noted, most of the natural resources in the western states were already owned by the federal government. The best course of action, they argued, was a long-term plan devised by national experts to maximize the long-term economic benefits of natural resources. To accomplish the mission, Roosevelt and Grinnell formed the Boone and Crockett Club, whose members were some of the best minds and influential men of the day. Its contingency of conservationists, scientists, politicians, and intellectuals became Roosevelt's closest advisers during his march to preserve wildlife and habitat across North America.
  • Preservationists: Preservationists, led by John Muir (1838–1914), argued that the conservation policies were not strong enough to protect the interest of the natural world because they continued to focus on the natural world as a source of economic production.

The debate between conservation and preservation reached its peak in the public debates over the construction of California's Hetch Hetchy dam in Yosemite National Park which supplies the water supply of San Francisco. Muir, leading the Sierra Club, declared that the valley must be preserved for the sake of its beauty: "No holier temple has ever been consecrated by the heart of man."

President Roosevelt put conservationist issues high on the national agenda. He worked with all the major figures of the movement, especially his chief advisor on the matter, Gifford Pinchot and was deeply committed to conserving natural resources. He encouraged the Newlands Reclamation Act of 1902 to promote federal construction of dams to irrigate small farms and placed 230 million acres (360,000 mi2 or 930,000 km2) under federal protection. Roosevelt set aside more federal land for national parks and nature preserves than all of his predecessors combined.

Roosevelt was a leader in conservation, fighting to end the waste of natural resources.

Roosevelt established the United States Forest Service, signed into law the creation of five national parks, and signed the year 1906 Antiquities Act, under which he proclaimed 18 new national monuments. He also established the first 51 bird reserves, four game preserves, and 150 national forests, including Shoshone National Forest, the nation's first. The area of the United States that he placed under public protection totals approximately 230,000,000 acres (930,000 km2).

Gifford Pinchot had been appointed by McKinley as chief of Division of Forestry in the Department of Agriculture. In 1905, his department gained control of the national forest reserves. Pinchot promoted private use (for a fee) under federal supervision. In 1907, Roosevelt designated 16 million acres (65,000 km2) of new national forests just minutes before a deadline.

In May 1908, Roosevelt sponsored the Conference of Governors held in the White House, with a focus on natural resources and their most efficient use. Roosevelt delivered the opening address: "Conservation as a National Duty".

In 1903 Roosevelt toured the Yosemite Valley with John Muir, who had a very different view of conservation, and tried to minimize commercial use of water resources and forests. Working through the Sierra Club he founded, Muir succeeded in 1905 in having Congress transfer the Mariposa Grove and Yosemite Valley to the federal government. While Muir wanted nature preserved for its own sake, Roosevelt subscribed to Pinchot's formulation, "to make the forest produce the largest amount of whatever crop or service will be most useful, and keep on producing it for generation after generation of men and trees."

Theodore Roosevelt's view on conservationism remained dominant for decades; Franklin D. Roosevelt authorised the building of many large-scale dams and water projects, as well as the expansion of the National Forest System to buy out sub-marginal farms. In 1937, the Pittman–Robertson Federal Aid in Wildlife Restoration Act was signed into law, providing funding for state agencies to carry out their conservation efforts.

While Theodore Roosevelt was one of the leading activists for the conservation movement in the United States, he also believed that the threats to the natural world were equally threats to white Americans. They held the belief that the cities, industries and factories that were overtaking the wilderness and threatening the native plants and animals were also consuming and threatening the racial vigor that they believed white Americans held which made them superior. Roosevelt was a big believer that white male virility depended on wildlife for its vigor, and that depleting wildlife would result in a much weaker nation. This lead Roosevelt to support the passing of many immigration restrictions, eugenics legislations and wildlife preservation laws. He drew much inspiration for his beliefs from Madison Grant, a well known American eugenicist and conservationist. Grant worked alongside Roosevelt in the American conservation movement and was even secretary and president of the Boone and Crockett Club. In 1916, Grant published the book "The Passing of the Great Race", which explained the hierarchy of races, with white, "Nordic" men at the top, and all other races below. The German translation of this book was used by Nazi Germany as the source for many of their beliefs.

The National Audubon Society was founded in 1905 with the priority of protecting/conserving various waterbird species. However, the first state-level Audubon group was created in 1896 by Harriet Hemenway and Minna B. Hall to convince women to refrain from buying hats made with bird feathers- a common practice at the time. The organization is named after John Audubon, a naturalist and legendary bird painter. The lesser known truth is that he was a slaveholder who also included many racist tales in his many books. Despite his views of racial inequality, Audubon did find black and indigenous people to be scientifically useful, often using their local knowledge in his books and relying on them to collect specimens for him.

Since 1970

Environmental reemerged on the national agenda in 1970, with Republican Richard Nixon playing a major role, especially with his creation of the Environmental Protection Agency. The debates over the public lands and environmental politics played a supporting role in the decline of liberalism and the rise of modern environmentalism. Although Americans consistently rank environmental issues as "important", polling data indicates that in the voting booth voters rank the environmental issues low relative to other political concerns.

The growth of the Republican party's political power in the inland West (apart from the Pacific coast) was facilitated by the rise of popular opposition to public lands reform. Successful Democrats in the inland West and Alaska typically take more conservative positions on environmental issues than Democrats from the Coastal states. Conservatives drew on new organizational networks of think tanks, industry groups, and citizen-oriented organizations, and they began to deploy new strategies that affirmed the rights of individuals to their property, protection of extraction rights, to hunt and recreate, and to pursue happiness unencumbered by the federal government at the expense of resource conservation.

In 2019, convivial conservation was an idea proposed by Bram Büscher and Robert Fletcher. Convivial conservation draws on social movements and concepts like environmental justice and structural change to create a post-capitalist approach to conservation.

Conservation in Costa Rica

Figure 1. Costa Rica divided into different areas of conservation

Although the conservation movement developed in Europe in the 18th century, Costa Rica as a country has been heralded its champion in the current times. Costa Rica hosts an astonishing number of species, given its size, having more animal and plant species than the US and Canada combined while being only 250 miles long and 150 miles wide. A widely accepted theory for the origin of this unusual density of species is the free mixing of species from both North and South America occurring on this "inter-oceanic" and "inter-continental" landscape. Preserving the natural environment of this fragile landscape, therefore, has drawn the attention of many international scholars.

Costa Rica has made conservation a national priority, and has been at the forefront of preserving its natural environment with over a quarter of its land designated as protected in some form, which is under the administrative control of SINAC (National System of Conservation Areas)  a division of MINAE (Ministry of Environment, Energy and Telecommunications). SINAC has subdivided the country into various zones depending on the ecological diversity of that region - these zones are depicted in figure 1.

The country has used this ecological diversity to its economic advantage in the form of a thriving ecotourism industry, putting its commitment to nature, on display to visitors from across the globe. It is estimated that a record 2.6 million foreigners visited the country in 2015, almost half the population of Costa Rica itself. This tourism is facilitated by the fact that Costa Rica has a stable democracy and has a human development index of 0.776, the highest for any country in Latin America.

It is also the only country in the world that generates more than 99% of its electricity from renewable sources, relying on hydropower (78%), wind (10%), geothermal energy (10%), biomass and solar (1%). Critics have pointed out however, that in achieving this milestone, the country has built several dams (providing the bulk of its electricity) some of which have negatively impacted indigenous communities as well as the local flora and fauna.

World Wide Fund for Nature

You know, when we first set up WWF, our objective was to save endangered species from extinction. But we have failed completely; we haven’t managed to save a single one. If only we had put all that money into condoms, we might have done some good.

— Sir Peter Scott, Founder of the World Wide Fund for Nature, Cosmos Magazine, 2010

The World Wide Fund for Nature (WWF) is an international non-governmental organization founded in 1961, working in the field of the wilderness preservation, and the reduction of human impact on the environment. It was formerly named the "World Wildlife Fund", which remains its official name in Canada and the United States.

WWF is the world's largest conservation organization with over five million supporters worldwide, working in more than 100 countries, supporting around 1,300 conservation and environmental projects. They have invested over $1 billion in more than 12,000 conservation initiatives since 1995. WWF is a foundation with 55% of funding from individuals and bequests, 19% from government sources (such as the World Bank, DFID, USAID) and 8% from corporations in 2014.

WWF aims to "stop the degradation of the planet's natural environment and to build a future in which humans live in harmony with nature." The Living Planet Report is published every two years by WWF since 1998; it is based on a Living Planet Index and ecological footprint calculation. In addition, WWF has launched several notable worldwide campaigns including Earth Hour and Debt-for-Nature Swap, and its current work is organized around these six areas: food, climate, freshwater, wildlife, forests, and oceans.

"Conservation Far" approach

A conservation-exploitation dichotomy has plagued a place many may not expect: Conservation institutions. Institutions such as the WWF have historically been the cause of the displacement and divide between native populations and the lands they inhabit. The overbearing reason behind this rather contradictory truth is because of the organization's historically colonial, paternalistic, and neoliberal approaches to conservation. Claus, in his article "Drawing the Sea Near: Satoumi and Coral Reef Conservation in Okinawa", expands on these approaches and their effectiveness, not as much in conservation, but in creating the value of and commercializing endangered flora and fauna. One way in which this has taken place is through a separation between people, even locals, and the nature spaces they aimed to protect. This is what Claus calls the "Conservation-Far" method, in which access to lands is completely relinquished upon the locals and tourists, by an external, foreign entity. This entity is largely unaware of the customs and values held by those within the territory surrounding nature and their role within it.

Claus relays the history of an Island in Japan, Shiraho, in which the people's traditional ways of tending to nature were lost due to modernization and the rise of a fast-paced lifestyle. It is the view of a "Conservation-Near" approach that would suggest a regeneration of these customs within the local area. This engages those near in proximity to the lands in the conservation efforts and holds them accountable for their direct effects on its preservation. Unlike the hands-on, full sensory experience permitted by conservation-near methodologies, conservation-far drills visuals and sight as being the main interaction medium between people and the environment. An emphasis on observation only stems from a deeper association with intellect and observation. The alternative to this is more of a bodily or "primitive" consciousness, which is associated with lower-intelligence and people of color. A new, integrated approach to conservation is being investigated in recent years by institutions such as WWF.

Evidence-based conservation

Evidence-based conservation is the application of evidence in nature conservation management actions and policy making. It is defined as systematically assessing scientific information from published, peer-reviewed publications and texts, practitioners' experiences, independent expert assessment, and local and indigenous knowledge on a specific conservation topic. This includes assessing the current effectiveness of different management interventions, threats and emerging problems and economic factors.

Evidence-based conservation was organized based on the observations that decision making in conservation was based on intuition and or practitioner experience often disregarding other forms of evidence of successes and failures (e.g. scientific information). This has led to costly and poor outcomes. Evidence-based conservation provides access to information that will support decision making through an evidence-based framework of "what works" in conservation.

The evidence-based approach to conservation is based on evidence-based practice which started in medicine and later spread to nursing, education, psychology and other fields. It is part of the larger movement towards evidence-based practices.

Areas of concern

Deforestation and overpopulation are issues affecting all regions of the world. The consequent destruction of wildlife habitat has prompted the creation of conservation groups in other countries, some founded by local hunters who have witnessed declining wildlife populations first hand. Also, it was highly important for the conservation movement to solve problems of living conditions in the cities and the overpopulation of such places.

Boreal forest and the Arctic

The idea of incentive conservation is a modern one but its practice has clearly defended some of the sub Arctic wildernesses and the wildlife in those regions for thousands of years, especially by indigenous peoples such as the Evenk, Yakut, Sami, Inuit and Cree. The fur trade and hunting by these peoples have preserved these regions for thousands of years. Ironically, the pressure now upon them comes from non-renewable resources such as oil, sometimes to make synthetic clothing which is advocated as a humane substitute for fur. (See Raccoon dog for case study of the conservation of an animal through fur trade.) Similarly, in the case of the beaver, hunting and fur trade were thought to bring about the animal's demise, when in fact they were an integral part of its conservation. For many years children's books stated and still do, that the decline in the beaver population was due to the fur trade. In reality however, the decline in beaver numbers was because of habitat destruction and deforestation, as well as its continued persecution as a pest (it causes flooding). In Cree lands, however, where the population valued the animal for meat and fur, it continued to thrive. The Inuit defend their relationship with the seal in response to outside critics.

Latin America (Bolivia)

The Izoceño-Guaraní of Santa Cruz Department, Bolivia, is a tribe of hunters who were influential in establishing the Capitania del Alto y Bajo Isoso (CABI). CABI promotes economic growth and survival of the Izoceno people while discouraging the rapid destruction of habitat within Bolivia's Gran Chaco. They are responsible for the creation of the 34,000 square kilometre Kaa-Iya del Gran Chaco National Park and Integrated Management Area (KINP). The KINP protects the most biodiverse portion of the Gran Chaco, an ecoregion shared with Argentina, Paraguay and Brazil. In 1996, the Wildlife Conservation Society joined forces with CABI to institute wildlife and hunting monitoring programs in 23 Izoceño communities. The partnership combines traditional beliefs and local knowledge with the political and administrative tools needed to effectively manage habitats. The programs rely solely on voluntary participation by local hunters who perform self-monitoring techniques and keep records of their hunts. The information obtained by the hunters participating in the program has provided CABI with important data required to make educated decisions about the use of the land. Hunters have been willing participants in this program because of pride in their traditional activities, encouragement by their communities and expectations of benefits to the area.

Africa (Botswana)

In order to discourage illegal South African hunting parties and ensure future local use and sustainability, indigenous hunters in Botswana began lobbying for and implementing conservation practices in the 1960s. The Fauna Preservation Society of Ngamiland (FPS) was formed in 1962 by the husband and wife team: Robert Kay and June Kay, environmentalists working in conjunction with the Batawana tribes to preserve wildlife habitat.

The FPS promotes habitat conservation and provides local education for preservation of wildlife. Conservation initiatives were met with strong opposition from the Botswana government because of the monies tied to big-game hunting. In 1963, BaTawanga Chiefs and tribal hunter/adventurers in conjunction with the FPS founded Moremi National Park and Wildlife Refuge, the first area to be set aside by tribal people rather than governmental forces. Moremi National Park is home to a variety of wildlife, including lions, giraffes, elephants, buffalo, zebra, cheetahs and antelope, and covers an area of 3,000 square kilometers. Most of the groups involved with establishing this protected land were involved with hunting and were motivated by their personal observations of declining wildlife and habitat.

Predation problem

From Wikipedia, the free encyclopedia

The predation problem or predation argument refers to the consideration of the harms experienced by animals due to predation as a moral problem, that humans may or may not have an obligation to work towards preventing. Discourse on this topic has, by and large, been held within the disciplines of animal and environmental ethics. The issue has particularly been discussed in relation to animal rights and wild animal suffering. Some critics have considered an obligation to prevent predation as untenable or absurd and have used the position as a reductio ad absurdum to reject the concept of animal rights altogether. Others have criticized any obligation implied by the animal rights position as environmentally harmful.

Responses from animal ethicists and rights advocates have been varied. Some have rejected the claim that animal rights as a position implies that we are obligated to prevent predation, while others have argued that the animal rights position does imply that predation is something that we should try to avert. Others have asserted that it is not something that we should do anything about now due to the risk that we could inadvertently cause significant harm, but that it is something that we may be able to effectively take action on in the future with improved knowledge and technologies.

Historical views

Problem of evil

Predation has historically been viewed as a natural evil within the context of the problem of evil and has been considered a moral concern for Christians who have engaged with theodicy. Natural evils have been sometimes thought of as something that humans should work towards alleviating, or as part of a greater good which justifies the existence of this type of evil. Thomas Aquinas advocated the latter view, arguing that "defects" in nature such as predation led to the "good of another, or even to the universal good" and that if "all evil were prevented, much good would be absent from the universe". Within Christian and Hebrew Scripture, there are several prophecies which describe a future Heaven or Earth where predation is no longer a feature of nature, including Isaiah's prophecy that "[t]he wolf shall live with the lamb, the leopard shall lie down with the kid, the calf and the lion and the fatling together, and a little child shall lead them."

In his notebooks (written between 1487 and 1505), Leonardo da Vinci questioned why nature was not structured in a way which meant that animals were not forced to consume each other to survive. David Hume made several observations about predation and suffering experienced by wild animals in Dialogues Concerning Natural Religion (1779), stating that the "stronger prey upon the weaker, and keep them in perpetual terror and anxiety".

William Paley, in Natural Theology, described predation as being the most challenging of God's work to establish the utility of, nevertheless, he defended predation as the means to deal with the potentially catastrophic effects of animals producing more offspring than can possibly survive.

The debate around predation and the problem of evil was significantly increased by the popularization of Charles Darwin's theory of natural selection. Some earlier Christians argued that violence in nature was a result of the fall of man, but evidence that predation has existed for millions of years before the evolution of humans and the concept of sin, indicates that while life has existed, there has never been a time where nature has been free from violence. Darwin himself questioned how the fact that the Ichneumonidae prey on the bodies of living caterpillars could be reconciled with the idea of an omnibenevolent God.

Criticism of moral judgements

Plutarch criticised the labelling of carnivorous animals such as lions, tigers and snakes as barbarous because for them killing is a necessity while for humans who can live off of "nature's beneficent fruits" killing is a "luxury and crime".

The writer Edward Augustus Kendall discussed predation in his book of moral fables The Canary Bird (1799), in which he argued that predatory behavior by animals should not be judged by human moral standards and that "a prejudice against particular creatures, for fancied acts of cruelty is absurd".

Philosophical pessimism

Giacomo Leopardi, the Italian poet and philosopher, in Operette morali (1827) engaged in a dialogue with Nature in "Dialogue between Nature and an Icelander", which uses the inevitability of predation—such as a squirrel fleeing from a rattlesnake, only to run into the snake's open mouth—as a moral indictment on nature's cannibalism of its own offspring. The inevitability of such cycles of destruction and creation was a cause for Leopardi's philosophical pessimism. In Zibaldone, published posthumously in 1898, Leopardi argued that predation is the ultimate indication of the evil design of nature.

Similar to Leopardi, the German philosopher Arthur Schopenhauer, in 1851, used the pain experienced by an animal being devoured by another as a refutation against the idea that the "pleasure in the world outweighs the pain".

Animal rights

Lewis Gompertz, an early animal rights advocate, and one of the first contemporary authors to address the problem of wild animal suffering, in the fifth chapter of his 1824 book Moral Inquiries on the Situation of Man and of Brutes, engaged in a dialogue, in which he asserted that animals devouring each other can be judged as wrong by the rules that we use to govern human lives and stated that "should I witness the attempt in any animal of destroying another, I would endeavour to frustrate it; though this might probably be wrong." He went on to argue that the extinction of carnivorous species would not be bad, claiming that the species of one animal is not more important than an equal number of another and that it would be possible for some carnivorous animals, like wolves, to instead sustain themselves on vegetables.

The American zoologist and animal rights philosopher J. Howard Moore, in The New Ethics (1907), labelled carnivorous species as "criminal" races whose "existence is a continual menace to the peace and well-being of the world" because the "fullness of their lives is dependent upon the emptiness and destruction of others". In the pamphlet Why I Am a Vegetarian, published in 1895, Moore described the Carnivora as "relentless brutes", whose existence is a travesty for ethics, justice and mercy. In Better-World Philosophy (1899), Moore argued that carnivorousness was the result of excessive egoism, a product of natural selection, stating "Life riots on life—tooth and talon, beak and paw". He went on to claim that the irredeemable nature of carnivorous species meant that they could not be reconciled with each other in his ideal arrangement of the universe, which he called a "Confederation of the Consciousnesses".

In 1903, the Scottish philosopher David G. Ritchie in response to Henry S. Salt's 1892 book Animals' Rights, claimed that giving animals rights would imply that we must "protect the weak among them against the strong" and to achieve this, carnivorous animals should be put to death or slowly starved by "permanent captivity and vegetarian diet". He considered this proposal absurd, stating that the "declaration of the rights of every creeping thing [is] to remain a mere hypocritical formula to gratify pug-loving sentimentalists".

Contemporary views

Animal ethics

In 1973, Australian philosopher Peter Singer argued that if humans were to try to prevent predation, such as from stopping lions killing gazelles, that it would likely increase the "net amount of animal suffering", but asserted that if hypothetically we could reduce suffering in the long-term, then it would be right to intervene.

The English philosopher Stephen R. L. Clark's "The Rights of Wild Things" (1979) is considered to be one of the first ethics papers to explicitly engage with predation as a problem. In the paper, Clark argues that the concept that humans are obligated to aid animals against predators is not absurd, but that it follows only in the abstract, not in practice.

Animal rights philosopher, Tom Regan in his 1983 book, The Case for Animal Rights, argued that humans have no obligation to prevent predation because carnivorous animals are not moral agents and as a result cannot violate the rights of the animals that they predate. Along these lines, Julius Kapembwa argues that "intervention in predation is neither required nor permitted by animal rights theory".

Steve Sapontzis, in his 1984 paper "Predation" argues against the idea that the problem of predation is a reductio ad absurdum for animal rights, instead, he claims that if we accept the view that we have an obligation to reduce avoidable animal suffering, then predation is something that we should work towards preventing if we can do so without inflicting greater suffering. Sapontzis concludes that whether humans choose to fulfil this particular obligation, or attempt to reduce other forms of avoidable suffering, is a question of where humans can do the most good.

In a 2003 paper, the economist Tyler Cowen advocates, from a utility, rights and holistic perspective, for the policing of nature to reduce the predatory activity of certain animals to help their victims.

The transhumanist philosopher David Pearce, in his 2009 essay, "Reprogramming Predators", claims that predation is an immense source of suffering in the world and that a "biosphere without suffering is technically feasible". He argues for the phased extinction of carnivorous species using immunocontraceptives or "reprogramming" them using gene editing so that their descendants become herbivores. Pearce lists and argues against a number of justifications used by people who think that suffering caused by predation does not matter and that it should be conserved in its current state, including a "television-based conception of the living world", "[s]elective realism" and "[a]daptive empathy deficits".

In 2010, Jeff McMahan published "The Meat Eaters", an op-ed for the New York Times on predation as a moral issue, in which he argued that preventing the massive amounts of suffering and death caused by predation would be a good thing and that the extinction of carnivorous species could be instrumentally good if this could be achieved without inflicting "ecological upheaval involving more harm than would be prevented by the end of predation". McMahan received a number of objections to his arguments and responded to these in another op-ed published in the same year, "Predators: A Response". He later published his arguments as a chapter titled "The Moral Problem of Predation", in the 2015 book Philosophy Comes to Dinner.

Peter Vallentyne argues that it is permissible for humans to intervene to help prey in limited ways, if the cost to humans is minimal, but that we should not eliminate predators. In the same way that we aid humans in need, when the cost to humans is minimal, humans might help wild animals in limited circumstances.

Some ethicists have made concrete proposals for reducing or preventing predation, including stopping the reintroduction of predators in locations where they have previously gone extinct and removing predators from wild areas.

Environmental ethics

In 1984, the British ecologist Felicity A. Huntingford published "Some ethical issues raised by studies of predation and aggression", in which she discusses ethical issues and implications regarding the staging of artificial encounters for studies of predator-prey interactions.

In the context of ecology, predation is considered to play a crucial and necessary role in ecosystems. This has led some writers, such as Michael Pollan, to reject predation as being a moral problem at all, stating "predation is not a matter of morality or politics; it, also, is a matter of symbiosis". Under Aldo Leopold's land ethic, native predators, as crucial components of biotic communities, are considered important to conserve.

The environmental philosopher J. Baird Callicott asserts that the implication of animal rights theory, namely that we should protect animals from predators, would "[n]ot only [result in] the (humane) eradication of predators destroy the community, it would destroy the species which are the intended beneficiaries of this misplaced morality. Many prey species depend upon predators to optimize their populations." Holmes Rolston III views predation as an essential natural process and driver of evolution, that is a "sad good" to be respected and valued. Ty Raterman, an environmentalist, has argued that predation is something that can be lamented without implying that we have an obligation to prevent it.

The environmental ethicist William Lynn has argued that from a welfare perspective predation "is necessary for the well-being of predators and prey" and essential for the maintenance of the integrity of the ecological communities. Larry Rasmussen, a Christian environmental ethicist, has argued that predation is "not a pattern of morality we praise and advocate".

Other uses of the term

"Predation problem" can also refer to the predation of animals who belong to species considered valuable to humans for economic reasons or conservation, such as domestic sheep predation by coyotes, farmed salmon predation by seals, the predation of animals who are hunted for sport or food and cat predation of wild animals; culling or removal of predatory animals may be carried out to reduce such incidents.

Seven Summits

From Wikipedia, the free encyclopedia

The Seven Summits are the highest mountains of each of the seven traditional continents. Climbing to the summit of all of them is regarded as a mountaineering challenge, first achieved on 30 April 1985 by Richard Bass. Climbing the Seven Summits and additionally reaching the North and South poles has been dubbed the Explorers Grand Slam.

Definition

The Seven Summits are composed of each of the highest mountain peaks on each of the continents. Different lists include slight variations, but generally the same core is maintained. The seven summits depend on the definition used for a continent – in particular the location of the border of that continent. This results in two major points of variation. The first one is Mont Blanc versus Mount Elbrus for Europe, which depends on whether the crest of the Greater Caucasus Mountains is taken to define the Greater Caucasus watershed which marks the continental boundary between Asia and Europe for the region between the Black and Caspian seas; this classification would place Mount Elbrus in Asia instead of Europe. The second one is Puncak Jaya (also known as "Carstensz Pyramid") versus Mount Kosciuszko for the continent of Australia, which depends on whether one includes the Sahul Shelf or only mainland Australia as the continent. This also gives rise to another list called the "Eight Summits", which includes both Puncak Jaya and Mount Kosciuszko along with the six summits on the other continents.

This creates several possible versions of the seven summits:

  • Everest, Aconcagua, Denali, Kilimanjaro, Vinson, Elbrus, Mount Wilhelm (Continent)
  • Everest, Aconcagua, Denali, Kilimanjaro, Vinson, Elbrus, Kosciuszko (the Bass version)
  • Everest, Aconcagua, Denali, Kilimanjaro, Vinson, Elbrus, Puncak Jaya (the Messner version)
  • Everest, Aconcagua, Denali, Kilimanjaro, Vinson, Mont Blanc, Mount Wilhelm (the Wilhelm version)
  • Everest, Aconcagua, Denali, Kilimanjaro, Vinson, Mont Blanc, Kosciuszko (the 1950s explorer Hackett version)
  • Everest, Aconcagua, Denali, Kilimanjaro, Vinson, Mont Blanc, Puncak Jaya
  • Everest, Aconcagua, Denali, Kilimanjaro, Vinson, Mauna Kea, Puncak Jaya / Kosciuszko (the tectonic version)

The concept Richard Bass and his climbing partner Frank Wells were pursuing was to be the first to stand atop the highest mountain on each continent. They pursued this goal as they defined it, climbing Aconcagua for South America, McKinley (now Denali) for North America, Kilimanjaro for Africa, Elbrus for Europe, Vinson for Antarctica, Kosciuszko for Australia, and finally Everest for Asia.

Definition using tectonic plates

Tectonic plates (see list of tectonic plates)

Using the largest tectonic plates, Asia and Europe could be grouped as Eurasia, and the very large Pacific Plate would have Mauna Kea as its highest mountain. Puncak Jaya is actually on the Maoke Plate, while Mount Wilhelm is on the Woodlark Plate, both of which are usually grouped with the larger Australian Plate. If not, then Mount Kosciuszko would revert to being the highest of that plate (see also list of highest points of Oceanian countries).

Australia

Mount Wilhelm

The highest mountain in mainland Australia is Mount Kosciuszko, 2,228 metres (7,310 ft) above sea level. However, the highest mountain on the Australian continent, which includes Australia and New Guinea, is Puncak Jaya, 4,884 m (16,024 ft) above sea level, in the Indonesian province of Papua and on the island of New Guinea, which shares the Sahul continental shelf with Australia. Mount Kosciuszko is easier to climb, being a four-hour, grade 3 return walk from the nearest car park, while Puncak Jaya is classed as a mountaineering expedition.

Some sources claim Mount Wilhelm (4,509 m (14,793 ft)) in Papua New Guinea's Bismarck Range (on the island of New Guinea, like Puncak Jaya) as the highest mountain on the Australian continent, on account of Indonesia being a part of Asia (see list of Southeast Asian mountains, which includes Puncak Jaya and other mountains in Western New Guinea, Indonesia). However, such a definition is political, not geophysical, and would mean that the western part of New Guinea changed continents in 1969.

In terms of Australia as a country, Mawson Peak (2,745 m (9,006 ft)) is higher than Kosciuszko. However, it is not located in Oceania, but on Heard Island, a small offshore island in the southern Indian Ocean. If excluding the island of New Guinea, then Aoraki / Mount Cook on the South Island of New Zealand is the highest mountain in Australasia at 3,724 m (12,218 ft).

Sources that list Mount Wilhelm as highest point in Oceania or show boundaries putting Puncak Jaya in Asia include: the United Nations, 7 Continent Summits, World Atlas, the CIA World Factbook, Canada Atlas, and Papua New Guinea PNG Trekking.

Europe

Mont Blanc summit

The generally accepted highest summit in Europe is Mount Elbrus (5,642 m or 18,510 ft) in the Caucasus, appearing on both the Bass and Messner lists. However, because the location of the boundary between Asia and Europe is not universally agreed upon, its inclusion in Europe is disputed: if the Kuma–Manych Depression is used as the geological border between Asia and Europe, the Caucasus and Elbrus lie wholly in Asia. If the Greater Caucasus watershed is used instead, Elbrus' peaks are wholly in Europe, albeit close to the border with Asia. Mont Blanc (4,810 m or 15,781 ft), lying on the border between France and Italy in the Graian Alps, is seen by some to be the highest mountain in Europe.

North America

Denali is the highest mountain peak in North America. The Caribbean Plate and the Panama Plate, both of which share geological processes with the North American continent, have their own highest mountain peaks:

South America

Chimborazo, farthest peak from the center of Earth and probably the greatest of the North Andes Plate

Aconcagua is the highest mountain peak in South America. The Altiplano Plate and the North Andes Plate, both of which share geological processes with the South American continent, have their own highest mountain peaks:

  • South America – Aconcagua (6,961 m or 22,838 ft)
  • Altiplano Plate – probably Nevado Sajama (6,542 m or 21,463 ft)
  • North Andes Plate – Chimborazo (6,263 m or 20,548 ft)

The Bass and Messner lists

The first Seven Summits list as postulated by Bass (the Bass or Kosciusko list) chose the highest mountain of mainland Australia, Mount Kosciuszko (2,228 m or 7,310 ft), to represent the Australian continent's highest summit. Reinhold Messner postulated another list (the Messner or Carstensz list), replacing Mount Kosciuszko with Indonesia's Puncak Jaya, or Carstensz Pyramid (4,884 m or 16,024 ft). Neither the Bass nor the Messner list includes Mont Blanc. From a mountaineering point of view, the Messner list is the more challenging one. Climbing Carstensz Pyramid has the character of an expedition, whereas the ascent of Kosciuszko is an easy hike. Indeed, Patrick Morrow used this argument to defend his choice to adhere to the Messner list, "Being a climber first and a collector second, I felt strongly that Carstensz Pyramid, the highest mountain in Australasia ... was a true mountaineer’s objective."

Mountaineering challenge

The mountaineering challenge to climb the Seven Summits is traditionally based on either the Bass or the Messner list. (It is assumed that most of the mountaineers who have completed the Seven Summits would have climbed Mont Blanc as well.) As of January 2010, approximately 275 climbers climbed all seven of the peaks from either the Bass or the Messner list; about 30% of those have climbed all of the eight peaks required to complete both lists.

History

Everest

In 1956, William D. Hackett (1918–1999), an American mountaineer, reached the top of five continents. He climbed Denali (then known as Mount McKinley) (1947), Aconcagua (1949), Kilimanjaro (1950), Kosciuszko (1956) and Mont Blanc (1956). In that time, Mont Blanc was considered to be the highest mountain of the European continent. Hackett made an attempt to climb Mount Vinson and obtained a permit for Mount Everest in 1960, but due to several circumstances (frostbite, lack of funds, etc.), he never made it to more than five summits.

In 1970, the Japanese mountaineer and adventurer Naomi Uemura (1941-1984) was the first person to reach five of the Seven Summits including Mount Everest. He climbed Mont Blanc (1966), Kilimanjaro (1966), Aconcagua (1968), Mount Everest (1970 solo) and Denali (1970 solo). After the first solo trip to the North Pole (1978), he planned to go on his own to Antarctica to climb Mount Vinson. In preparation for the Antarctica expedition, he did a solo winter ascent of Denali (1984). On the descent he disappeared in a winter storm.

In 1978, the Italian mountaineer Reinhold Messner was the first person to reach six of the Seven Summits (1971 Puncak Jaya, 1974 Aconcagua, 1976 Mount McKinley (now Denali), 1978 Kilimanjaro, 1978 Mount Everest). For Messner, Carstensz Pyramid (Puncak Jaya) was the highest peak in Australia (Messner list), but in 1983, he climbed Mount Kosciuszko to also satisfy the other geographic definition of Australia. In the same year, Messner climbed Mount Elbrus and declared that it was the true highest peak of Europe. This definition was quickly accepted by others in the mountaineering community. Finally in 1986, he climbed Mount Vinson. At that time, he was only the fifth person to reach the Seven Summits.

Mount Kosciuszko summit

In 1985, Richard Bass, a businessman and amateur mountaineer, was the first man to climb all Seven Summits. In only one year, 1983, he climbed six peaks: Aconcagua, Denali, Kilimanjaro, Mount Elbrus, Mount Vinson and Mount Kosciuszko. All of these climbs he did together with his companion Frank Wells and different mountain guides. Beginning in 1983, Bass and Wells made various guided attempts to climb Mount Everest, the highest and most difficult peak in the list. On 30 April 1985, Bass reached the summit of Mount Everest in a party without Wells, guided by the American professional mountaineer David Breashears. He then co-authored the book Seven Summits, which covered the undertaking. Later in 1985, American mountaineer Gerry Roach became the second person to climb the Seven Summits.

In 1986, the Canadian mountaineer Patrick Morrow became the first man to climb the Seven Summits in the Carstensz version (Messner list). He climbed Denali (1977), Aconcagua (1981), Mount Everest (1982), Kilimanjaro (1983), Mount Kosciuszko (1983), Mount Vinson (1985), Mount Elbrus (1985) and finally the Puncak Jaya (Carstensz Pyramid) on May 7, 1986. Morrow was also the first to complete both lists (Bass and Messner).

In 1990, Rob Hall and Gary Ball became the first to complete the "Seven Summits" in seven months. Using the Bass list, they started with Everest on 10 May 1990, and finished with Vinson on 12 December 1990, hours before the seven-month deadline.

In 1992, Junko Tabei became the first woman to complete the "Seven Summits". Mary "Dolly" Lefever became the first American woman to climb the "Seven Summits" on March 11, 1993, when she climbed Australia's Mount Kosciuszko. Earlier in 1993, she had become the oldest surviving woman to have reached the summit of Mount Everest; she was 47 years old. In January 1996, Chris Haver became the first American to climb and ski all seven summits. Yasuko Namba was famous in her native Japan for becoming the second Japanese woman to reach all of the Seven Summits including Everest, where she died during the storm of May 1996 during her descent.

A climber ascending Mount Vinson

In 2000, Croatian mountaineer Stipe Božić completed the Seven Summits. In May 2002, Susan Ershler and her husband, Phil, became the first married couple to climb the "Seven Summits" together. The first person to complete Seven Summits without the use of supplemental oxygen on Mount Everest is Reinhold Messner. Miroslav Caban is the second climber to finish the project without supplemental oxygen on Everest (finished in 2005 with Carstensz). Ed Viesturs also summitted all peaks without supplemental oxygen. Between 2002 and 2007, Austrian climber Christian Stangl completed the Seven Summits (Messner list), climbing alone and without supplemental oxygen, and reported a record total ascent time from respective base camp to summit of 58 hours and 45 minutes.

On 17 May 2006, Rhys Jones became the youngest person to complete the Seven Summits (Bass list) at the age of exactly 20 years. Notable climbers who had previously been the youngest to complete the Seven Summits include Rob Hall in 1990 and David Keaton in 1995. In May 2007, Samantha Larson completed the seven at the age of 18 years and 220 days (she is still the youngest woman to have climbed the Seven Summits). Johnny Strange finished climbing the summits at the age of 17 years and 161 days in June 2009. On 26 May 2011, at 6:45 Nepali time, Geordie Stewart became the youngest Briton to complete the Seven Summits at the age of 22 years and 21 days. In 2009-10, Indian mountaineer Krushnaa Patil made a bid for the fastest woman to complete the challenge; she fell short of the challenge when, in May 2009, her seventh and final summit bid on Denali was halted by her guide's illness. George Atkinson then became the youngest person in the world to complete the round aged 16 years 362 days. On 24 December 2011, the record was once again beaten, by American Jordan Romero, who completed the challenge at the age of 15 years, 5 months and 12 days by climbing Vinson.

In October 2006, Kit Deslauriers became the first person to have skied down (parts of) all seven peaks (Bass list). Three months later, in January 2007, Swedes Olof Sundström and Martin Letzter completed their Seven Summits skiing project by skiing down (parts of) Carstensz Pyramid, thus becoming the first and only people to have skied both lists.

Indian mountaineer Malli Mastan Babu also had the eminence of setting a Guinness world record by surmounting the Seven Summits in 172 days in 2006. The world record for completion of the Messner and Bass list was 136 days, by Danish climber Henrik Kristiansen in 2008. Kristiansen completed the summits in the following order: Vinson on Jan 21, Aconcagua on Feb 6, Kosciuszko on Feb 13, Kilimanjaro on Mar 1, Carstensz Pyramid on Mar 14, Elbrus on May 8, Everest on May 25, spending just 22 days on the mountain (normally, expeditions take up to two months acclimatizing, laying ropes, etc.) and finally Denali on June 5, beating Ian McKeever's previous record by 20 days. Vern Tejas set the new record for the same, in 134 days. Tejas began with summiting Vinson on 18 January 2010 and ended with summiting Denali on May 31. This was Tejas' ninth time to complete the Bass Seven Summits.

In January 2010, the Spanish climber Carlos Soria Fontán, at the age of 71, completed the seven summits (Messner list) after reaching the summit of Kilimanjaro. He had climbed the first one in 1968. On 23 May 2010, AC Sherpa summited Mount Everest as his last and final conquest of the Seven Summits (Bass list). In doing this, he set a new record by climbing the Seven Summits within 42 climbing days. Additionally, when climbing Mount Kilimanjaro (via Marangu) he summited in just 16 hours and 37 minutes, easily beating the previous record of 18 hours.

As of 24 December 2011, it is reported that only 118 people have climbed the Seven Summits if one assumes "full" completion of the quest requires climbing the "Eight Summits" across both the Bass and Messner lists (climbing both Carstensz Pyramid and Kosciusko in addition to the other six "undisputed" summits such as Everest). 231 persons have climbed the Messner list, while 234 have completed the Bass list. 348 have done either the Bass or Messner list.

In 2013, Vanessa O'Brien became the fastest female to complete the Seven Summits (including Carstensz Pyramid), finishing in 10 months. Cason Crane became the first openly gay man to climb the Seven Summits. On 21 November 2013, Werner Berger (Canada, ex-South African), at the age of 76 years and 129 days, became the oldest person in the world to complete the Seven Summits after a 6-day jungle trek to Carstensz Pyramid. In 2013, Cheryl and Nikki Bart became the first mother-daughter team to complete the Seven Summits.

On 16 December 2014, Tashi and Nungshi Malik became the world's first twins and siblings to complete the Seven Summits (Messner list). Colin O'Brady broke the record for the Messner and Bass lists in 131 days, summiting Vinson on 17 January 2016 and completing with Denali on 27 May 2016.

The youngest person to complete both the Seven Summits and the Volcanic Seven Summits is Satyarup Siddhanta from India. He completed the feat on 15 Jan 2019 after summitting Mt Sidley, Antarctica at the age of 35 years 261 days breaking the record of Daniel Bull from Australia . He was also the first Indian to accomplish the feat and created a Guinness world record.

On 6 January 2018, Chris Bombardier reached the summit of Mount Vinson, becoming the first person with hemophilia to complete the Seven Summits (Messner list). On 23 June 2018, Silvia Vasquez-Lavado reached the summit of Denali, becoming the first openly gay woman to complete the Seven Summits (including Carstensz Pyramid). On 4 January 2019, Arunima Sinha reached the summit of Mount Vinson, becoming the first female amputee to complete the Seven Summits (including Carstensz Pyramid).

Criticism

K2, about 800 feet (240 m) shorter than Everest

Alpinism author Jon Krakauer (1997) wrote in Into Thin Air that it would be a bigger challenge to climb the second-highest peak of each continent, known as the Seven Second Summits – a feat that was not accomplished until January 2013. This discussion had previously been published in an article titled The Second Seven Summits in Rock & Ice Magazine (#77) authored by the mountaineer and Seven Summits completer David Keaton. This is especially true for Asia, as K2 (8,611 m) demands greater technical climbing skills than Everest (8,848 m), while altitude-related factors such as the thinness of the atmosphere, high winds and low temperatures remain much the same. Some of those completing the seven ascents are aware of the magnitude of the challenge. In 2000, in a foreword to Steve Bell et al., Seven Summits, Morrow opined "[t]he only reason Reinhold [Messner] wasn’t the first person to complete the seven was that he was too busy gambolling up the 14 tallest mountains in the world."

Defence

Bill Allen, who completed the Seven Summits twice, said that getting to the summit never gets old. The 8000ers are all in East Asia; Nepal, China, India and Pakistan in a more narrow region of Earth, and many of the climbs are quite dangerous with several climbers dying short of completing all 14. Another problem is that while there are 14 main summits, there are additional sub-peaks over 8000 m. Indeed, in 2013, authorities were considering officially recognizing some additional peaks as 8000ers.

Impact and related climbing list concepts

Kanchenjunga is the world's third highest mountain ("K3"); it tops out less than 100 feet (30 m) shorter than K2.

One idea is to climb shorter peaks rather than the highest such as with the Seven Second Summits and Seven Third Summits. The Explorers Grand Slam includes the Seven Summits and both poles. Like the number one list, the number two and three lists is subject to the Bass vs. Messner geophysical/political dichotomy.

Number twos

A Seven Second Summits collection was first achieved in January 2013 by Christian Stangl. It is considered to be a more difficult mountaineering challenge than the standard Seven Summits, even if the peaks are lower.
