Vitalism

From Wikipedia, the free encyclopedia
The synthesis of urea in the early 19th century from inorganic compounds was counterevidence for the vitalist hypothesis that only organisms could make the components of living things.

Vitalism is the belief that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things". Where vitalism explicitly invokes a vital principle, that element is often referred to as the "vital spark", "energy" or "élan vital", which some equate with the soul. In the 18th and 19th centuries vitalism was discussed among biologists, between those who felt that the known mechanics of physics would eventually explain the difference between life and non-life and vitalists who argued that the processes of life could not be reduced to a mechanistic process. Some vitalist biologists proposed testable hypotheses meant to show inadequacies with mechanistic explanations, but these experiments failed to provide support for vitalism. Biologists now consider vitalism in this sense to have been refuted by empirical evidence, and hence regard it as a superseded scientific theory.

Vitalism has a long history in medical philosophies: many traditional healing practices posited that disease results from some imbalance in vital forces.

History

Ancient times

The notion that bodily functions are due to a vitalistic principle existing in all living creatures has roots going back at least to ancient Egypt. In Greek philosophy, the Milesian school proposed natural explanations deduced from materialism and mechanism. However, by the time of Lucretius, this account was supplemented, (for example, by the unpredictable clinamen of Epicurus), and in Stoic physics, the pneuma assumed the role of logos. Galen believed the lungs draw pneuma from the air, which the blood communicates throughout the body.

Medieval

In Europe, medieval physics was influenced by the idea of pneuma, helping to shape later aether theories.

Early modern

Vitalists included English anatomist Francis Glisson (1597–1677) and the Italian doctor Marcello Malpighi (1628–1694). Caspar Friedrich Wolff (1733–1794) is considered to be the father of epigenesis in embryology, that is, he marks the point when embryonic development began to be described in terms of the proliferation of cells rather than the incarnation of a preformed soul. However, this degree of empirical observation was not matched by a mechanistic philosophy: in his Theoria Generationis (1759), he tried to explain the emergence of the organism by the actions of a vis essentialis (an organizing, formative force), stating "All believers in epigenesis are vitalists." Carl Reichenbach (1788–1869) later developed the theory of Odic force, a form of life-energy that permeates living things. 

In the 17th century, modern science responded to Newton's action at a distance and the mechanism of Cartesian dualism with vitalist theories: that whereas the chemical transformations undergone by non-living substances are reversible, so-called "organic" matter is permanently altered by chemical transformations (such as cooking).

As worded by Charles Birch and John B. Cobb, "the claims of the vitalists came to the fore again" in the 18th century: "[Georg Ernst] Stahl's followers were active as were others, such as the physician genius Francis Xavier Bichat of the Hotel Dieu." However, "Bichat moved from the tendency typical of the French vitalistic tradition to progressively free himself from metaphysics in order to combine with hypotheses and theories which accorded to the scientific criteria of physics and chemistry." John Hunter recognised "a 'living principle' in addition to mechanics."

Johann Friedrich Blumenbach also was influential in establishing epigenesis in the life sciences in 1781 with his publication of Über den Bildungstrieb und das Zeugungsgeschäfte. Blumenbach cut up freshwater Hydra and established that the removed parts would regenerate. He inferred the presence of a "formative drive" (Bildungstrieb) in living matter. But he pointed out that this name,
like names applied to every other kind of vital power, of itself, explains nothing: it serves merely to designate a peculiar power formed by the combination of the mechanical principle with that which is susceptible of modification.

19th century

Louis Pasteur argued that only life could catalyse fermentation. Painting by Albert Edelfelt, 1885

Jöns Jakob Berzelius, one of the early 19th century fathers of modern chemistry, argued that a regulative force must exist within living matter to maintain its functions. Vitalist chemists predicted that organic materials could not be synthesized from inorganic components, but Friedrich Wöhler synthesised urea from inorganic components in 1828. However, contemporary accounts do not support the common belief that vitalism died when Wöhler made urea. This Wöhler Myth, as historian Peter Ramberg called it, originated from a popular history of chemistry published in 1931, which, "ignoring all pretense of historical accuracy, turned Wöhler into a crusader who made attempt after attempt to synthesize a natural product that would refute vitalism and lift the veil of ignorance, until 'one afternoon the miracle happened'".

Between 1833 and 1844, Johannes Peter Müller wrote a book on physiology called Handbuch der Physiologie, which became the leading textbook in the field for much of the nineteenth century. The book showed Müller's commitments to vitalism; he questioned why organic matter differs from inorganic, then proceeded to chemical analyses of the blood and lymph. He describes in detail the circulatory, lymphatic, respiratory, digestive, endocrine, nervous, and sensory systems in a wide variety of animals but explains that the presence of a soul makes each organism an indivisible whole. He also claimed the behavior of light and sound waves showed that living organisms possessed a life-energy for which physical laws could never fully account.

Louis Pasteur (1822–1895) after his famous rebuttal of spontaneous generation, performed several experiments that he felt supported vitalism. According to Bechtel, Pasteur "fitted fermentation into a more general programme describing special reactions that only occur in living organisms. These are irreducibly vital phenomena." Rejecting the claims of Berzelius, Liebig, Traube and others that fermentation resulted from chemical agents or catalysts within cells, Pasteur concluded that fermentation was a "vital action".

20th century

Hans Driesch (1867–1941) interpreted his experiments as showing that life is not run by physicochemical laws. His main argument was that when one cuts up an embryo after its first division or two, each part grows into a complete adult. Driesch's reputation as an experimental biologist deteriorated as a result of his vitalistic theories, which scientists have seen since his time as pseudoscience. Vitalism is a superseded scientific hypothesis, and the term is sometimes used as a pejorative epithet. Ernst Mayr (1904–2005) wrote:
It would be ahistorical to ridicule vitalists. When one reads the writings of one of the leading vitalists like Driesch one is forced to agree with him that many of the basic problems of biology simply cannot be solved by a philosophy as that of Descartes, in which the organism is simply considered a machine... The logic of the critique of the vitalists was impeccable.
Vitalism has become so disreputable a belief in the last fifty years that no biologist alive today would want to be classified as a vitalist. Still, the remnants of vitalist thinking can be found in the work of Alistair Hardy, Sewall Wright, and Charles Birch, who seem to believe in some sort of nonmaterial principle in organisms.
Other vitalists included Johannes Reinke and Oscar Hertwig. Reinke used the word neovitalism to describe his work, claiming that it would eventually be verified through experimentation, and that it was an improvement over the other vitalistic theories. The work of Reinke influenced Carl Jung.

John Scott Haldane adopted an anti-mechanist approach to biology and an idealist philosophy early on in his career. Haldane saw his work as a vindication of his belief that teleology was an essential concept in biology. His views became widely known with his first book Mechanism, life and personality in 1913. Haldane borrowed arguments from the vitalists to use against mechanism; however, he was not a vitalist. Haldane treated the organism as fundamental to biology: "we perceive the organism as a self-regulating entity", "every effort to analyze it into components that can be reduced to a mechanical explanation violates this central experience". The work of Haldane was an influence on organicism

Haldane also stated that a purely mechanist interpretation can not account for the characteristics of life. Haldane wrote a number of books in which he attempted to show the invalidity of both vitalism and mechanist approaches to science. Haldane explained:
We must find a different theoretical basis of biology, based on the observation that all the phenomena concerned tend towards being so coordinated that they express what is normal for an adult organism.

By 1931, biologists had "almost unanimously abandoned vitalism as an acknowledged belief."

Emergentism

Some aspects of contemporary science make reference to emergent processes; those in which the properties of a system cannot be fully described in terms of the properties of the constituents. This may be because the properties of the constituents are not fully understood, or because the interactions between the individual constituents are also important for the behavior of the system. 

Whether emergence should be grouped with traditional vitalist concepts is a matter of semantic controversy. According to Emmeche et al. (1997):
On the one hand, many scientists and philosophers regard emergence as having only a pseudo-scientific status. On the other hand, new developments in physics, biology, psychology, and cross-disciplinary fields such as cognitive science, artificial life, and the study of non-linear dynamical systems have focused strongly on the high level 'collective behaviour' of complex systems, which is often said to be truly emergent, and the term is increasingly used to characterize such systems.
Emmeche et al. (1998) state that "there is a very important difference between the vitalists and the emergentists: the vitalist's creative forces were relevant only in organic substances, not in inorganic matter. Emergence hence is creation of new properties regardless of the substance involved." "The assumption of an extra-physical vitalis (vital force, entelechy, élan vital, etc.), as formulated in most forms (old or new) of vitalism, is usually without any genuine explanatory power. It has served altogether too often as an intellectual tranquilizer or verbal sedative—stifling scientific inquiry rather than encouraging it to proceed in new directions."

Mesmerism

Franz Mesmer proposed the vitalist force of magnétisme animal in animals with breath.
 
A popular vitalist theory of the 18th century was "animal magnetism", in the theories of Franz Mesmer (1734–1815). However, the use of the (conventional) English term animal magnetism to translate Mesmer's magnétisme animal can be misleading for three reasons:
  • Mesmer chose his term to clearly distinguish his variant of magnetic force from those referred to, at that time, as mineral magnetism, cosmic magnetism and planetary magnetism.
  • Mesmer felt that this particular force/power only resided in the bodies of humans and animals.
  • Mesmer chose the word "animal," for its root meaning (from Latin animus="breath") specifically to identify his force as a quality that belonged to all creatures with breath; viz., the animate beings: humans and animals.
Mesmer's ideas became so influential that King Louis XVI of France appointed two commissions to investigate mesmerism; one was led by Joseph-Ignace Guillotin, the other, led by Benjamin Franklin, included Bailly and Lavoisier. The commissioners learned about Mesmeric theory, and saw its patients fall into fits and trances. In Franklin's garden, a patient was led to each of five trees, one of which had been "mesmerized"; he hugged each in turn to receive the "vital fluid," but fainted at the foot of a 'wrong' one. At Lavoisier's house, four normal cups of water were held before a "sensitive" woman; the fourth produced convulsions, but she calmly swallowed the mesmerized contents of a fifth, believing it to be plain water. The commissioners concluded that "the fluid without imagination is powerless, whereas imagination without the fluid can produce the effects of the fluid."

Medical philosophies

Vitalism has a long history in medical philosophies: many traditional healing practices posited that disease results from some imbalance in vital forces. In the Western tradition founded by Hippocrates, these vital forces were associated with the four temperaments and humours; Eastern traditions posited an imbalance or blocking of qi or prana. One example of a similar notion in Africa is the Yoruba concept of ase. Today forms of vitalism continue to exist as philosophical positions or as tenets in some religious traditions.

Complementary and alternative medicine therapies include energy therapies, associated with vitalism, especially biofield therapies such as therapeutic touch, Reiki, external qi, chakra healing and SHEN therapy. In these therapies, the "subtle energy" field of a patient is manipulated by a practitioner. The subtle energy is held to exist beyond the electromagnetic energy produced by the heart and brain. Beverly Rubik describes the biofield as a "complex, dynamic, extremely weak EM field within and around the human body...."

The founder of homeopathy, Samuel Hahnemann, promoted an immaterial, vitalistic view of disease: "...they are solely spirit-like (dynamic) derangements of the spirit-like power (the vital principle) that animates the human body." The view of disease as a dynamic disturbance of the immaterial and dynamic vital force is taught in many homeopathic colleges and constitutes a fundamental principle for many contemporary practising homeopaths.

Criticism

The 17th century French playwright Molière mocked vitalism in his 1673 play Le Malade imaginaire.

Vitalism has sometimes been criticized as begging the question by inventing a name. Molière had famously parodied this fallacy in Le Malade imaginaire, where a quack "answers" the question of "Why does opium cause sleep?" with "Because of its dormitive virtue (i.e., soporific power)." Thomas Henry Huxley compared vitalism to stating that water is the way it is because of its "aquosity". His grandson Julian Huxley in 1926 compared "vital force" or élan vital to explaining a railroad locomotive's operation by its élan locomotif ("locomotive force").

Another criticism is that vitalists have failed to rule out mechanistic explanations. This is rather obvious in retrospect for organic chemistry and developmental biology, but the criticism goes back at least a century. In 1912, Jacques Loeb published The Mechanistic Conception of Life, in which he described experiments on how a sea urchin could have a pin for its father, as Bertrand Russell put it (Religion and Science). He offered this challenge:
"... we must either succeed in producing living matter artificially, or we must find the reasons why this is impossible." (pp. 5–6)
Loeb addressed vitalism more explicitly:
"It is, therefore, unwarranted to continue the statement that in addition to the acceleration of oxidations the beginning of individual life is determined by the entrance of a metaphysical "life principle" into the egg; and that death is determined, aside from the cessation of oxidations, by the departure of this "principle" from the body. In the case of the evaporation of water we are satisfied with the explanation given by the kinetic theory of gases and do not demand that to repeat a well-known jest of Huxley the disappearance of the "aquosity" be also taken into consideration." (pp. 14–15)
Bechtel states that vitalism "is often viewed as unfalsifiable, and therefore a pernicious metaphysical doctrine."[1] For many scientists, "vitalist" theories were unsatisfactory "holding positions" on the pathway to mechanistic understanding. In 1967, Francis Crick, the co-discoverer of the structure of DNA, stated "And so to those of you who may be vitalists I would make this prophecy: what everyone believed yesterday, and you believe today, only cranks will believe tomorrow."

While many vitalistic theories have in fact been falsified, notably Mesmerism, the pseudoscientific retention of untested and untestable theories continues to this day. Alan Sokal published an analysis of the wide acceptance among professional nurses of "scientific theories" of spiritual healing. (Pseudoscience and Postmodernism: Antagonists or Fellow-Travelers?). Use of a technique called therapeutic touch was especially reviewed by Sokal, who concluded, "nearly all the pseudoscientific systems to be examined in this essay are based philosophically on vitalism" and added that "Mainstream science has rejected vitalism since at least the 1930s, for a plethora of good reasons that have only become stronger with time."

Joseph C. Keating, Jr. discusses vitalism's past and present roles in chiropractic and calls vitalism "a form of bio-theology." He further explains that:
"Vitalism is that rejected tradition in biology which proposes that life is sustained and explained by an unmeasurable, intelligent force or energy. The supposed effects of vitalism are the manifestations of life itself, which in turn are the basis for inferring the concept in the first place. This circular reasoning offers pseudo-explanation, and may deceive us into believing we have explained some aspect of biology when in fact we have only labeled our ignorance. 'Explaining an unknown (life) with an unknowable (Innate),' suggests chiropractor Joseph Donahue, 'is absurd'."
Keating views vitalism as incompatible with scientific thinking:
"Chiropractors are not unique in recognizing a tendency and capacity for self-repair and auto-regulation of human physiology. But we surely stick out like a sore thumb among professions which claim to be scientifically based by our unrelenting commitment to vitalism. So long as we propound the 'One cause, one cure' rhetoric of Innate, we should expect to be met by ridicule from the wider health science community. Chiropractors can't have it both ways. Our theories cannot be both dogmatically held vitalistic constructs and be scientific at the same time. The purposiveness, consciousness and rigidity of the Palmers' Innate should be rejected."
Keating also mentions Skinner's viewpoint:
"Vitalism has many faces and has sprung up in many areas of scientific inquiry. Psychologist B.F. Skinner, for example, pointed out the irrationality of attributing behavior to mental states and traits. Such 'mental way stations,' he argued, amount to excess theoretical baggage which fails to advance cause-and-effect explanations by substituting an unfathomable psychology of 'mind'."
According to Williams, "[t]oday, vitalism is one of the ideas that form the basis for many pseudoscientific health systems that claim that illnesses are caused by a disturbance or imbalance of the body's vital force." "Vitalists claim to be scientific, but in fact they reject the scientific method with its basic postulates of cause and effect and of provability. They often regard subjective experience to be more valid than objective material reality."

Victor Stenger states that the term "bioenergetics" "is applied in biochemistry to refer to the readily measurable exchanges of energy within organisms, and between organisms and the environment, which occur by normal physical and chemical processes. This is not, however, what the new vitalists have in mind. They imagine the bioenergetic field as a holistic living force that goes beyond reductionist physics and chemistry."

Such a field is sometimes explained as electromagnetic, though some advocates also make confused appeals to quantum physics. Joanne Stefanatos states that "The principles of energy medicine originate in quantum physics." Stenger offers several explanations as to why this line of reasoning may be misplaced. He explains that energy exists in discrete packets called quanta. Energy fields are composed of their component parts and so only exist when quanta are present. Therefore, energy fields are not holistic, but are rather a system of discrete parts that must obey the laws of physics. This also means that energy fields are not instantaneous. These facts of quantum physics place limitations on the infinite, continuous field that is used by some theorists to describe so-called "human energy fields". Stenger continues, explaining that the effects of EM forces have been measured by physicists as accurately as one part in a billion and there is yet to be any evidence that living organisms emit a unique field.

Vitalistic thinking has also been identified in the naive biological theories of children: "Recent experimental results show that a majority of preschoolers tend to choose vitalistic explanations as most plausible. Vitalism, together with other forms of intermediate causality, constitute unique causal devices for naive biology as a core domain of thought."

Green marketing

From Wikipedia, the free encyclopedia
Green marketing is the marketing of products that are presumed to be environmentally safe. It incorporates a broad range of activities, including product modification, changes to the production process, sustainable packaging, as well as modifying advertising. Yet defining green marketing is not a simple task where several meanings intersect and contradict each other; an example of this will be the existence of varying social, environmental and retail definitions attached to this term. Other similar terms used are environmental marketing and ecological marketing.

Green, environmental and eco-marketing are part of the new marketing approaches which do not just refocus, adjust or enhance existing marketing thinking and practice, but seek to challenge those approaches and provide a substantially different perspective. In more detail green, environmental and eco-marketing belong to the group of approaches which seek to address the lack of fit between marketing as it is currently practiced and the ecological and social realities of the wider marketing environment.

The legal implications of marketing claims call for caution or overstated claims can lead to regulatory or civil challenges. In the United States, the Federal Trade Commission provides some guidance on environmental marketing claims.This Commission is expected to do an overall review of this guidance, and the legal standards it contains, in 2011.

History

The term Green Marketing came into prominence in the late 1980s and early 1990s.[3] The proceedings of this workshop resulted in one of the first books on green marketing entitled "Ecological Marketing".

The Corporate Social Responsibility (CSR) Reports started with the ice cream seller Ben & Jerry's where the financial report was supplemented by a greater view on the company's environmental impact. In 1987 a document prepared by the World Commission on Environment and Development defined sustainable development as meeting “the needs of the present without compromising the ability of future generations to meet their own need”, this became known as the Brundtland Report and was another step towards widespread thinking on sustainability in everyday activity. Two tangible milestones for the first wave of green marketing came in the form of published books: Green Marketing by Ken Peattie (1992) in the United Kingdom and Green Marketing: Challenges & Opportunities for the New Marketing Age by Jacquelyn Ottman (1993) in the United States of America.

According to Jacquelyn Ottman, (author of "The New Rules of Green Marketing: Strategies, Tools, and Inspiration for Sustainable Branding" (Greenleaf Publishing and Berrett-Koehler Publishers, February 2011)) from an organizational standpoint, environmental considerations should be integrated into all aspects of marketing — new product development and communications and all points in between. The holistic nature of green also suggests that besides suppliers and retailers new stakeholders be enlisted, including educators, members of the community, regulators, and NGOs. Environmental issues should be balanced with primary customer needs.

The "Green consumerism" movements in the U.S. and other countries have struggled to reach critical mass and influence. However, public opinion polls taken since the late 1980s have shown consistently that a significant percentage of consumers in the U.S. and elsewhere profess a strong willingness to favor environmentally conscious products and companies. One of green marketing's challenges is the lack of standards or public consensus about what constitutes "green," according to Joel Makower, a writer on green marketing. This lack of consensus—by consumers, marketers, activists, regulators, and influential people—has slowed the growth of green products, says Makower, because companies are often reluctant to promote their green attributes, and consumers are often skeptical about claims.

Despite these challenges, green marketing has continued to gain adherents, particularly in light of growing global concern about climate change. This concern has led more companies to advertise their commitment to reduce their climate impacts, and the effect this is having on their products and services.

Greenhouse gas reduction market

The emerging greenhouse gas reduction market can potentially catalyze projects with important local environmental, economic, and quality-of-life benefits. The Kyoto Protocol’s Clean Development Mechanism (CDM), for example, enables trading between industrial and developing nations, providing a framework that can result in capital flows to environmentally beneficial development activities. Although the United States is not participating in the Kyoto Protocol, several US programs enable similar transactions on a voluntary and regulatory basis.

While international trade in greenhouse gas reductions holds substantial promise as a source of new funding for sustainable development, this market can be largely inaccessible to many smaller-scale projects, remote communities, and least developed localities. To facilitate participation and broaden the benefits, several barriers must be overcome, including: a lack of market awareness among stakeholders and prospective participants; specialized, somewhat complicated participation rules; and the need for simplified participation mechanisms for small projects, without which transaction costs can overwhelm the financial benefits of participation. If the barriers are adequately addressed, greenhouse gas trading can play an important role supporting activities that benefit people’s lives and the environment.

Popularity and effectiveness

Ongoing debate

The popularity of such marketing approach and its effectiveness is hotly debated. Supporters claim that environmental appeals are actually growing in number–the Energy Star label, for example, now appears on 11,000 different companies' models in 38 product categories, from washing machines and light bulbs to skyscrapers and homes. However, despite the growth in the number of green products, green marketing is on the decline as the primary sales pitch for products. Shel Horowitz, a green marketer for over 30 years and primary author of Guerrilla marketing Goes Green states that to market effectively, green businesses need to market to three different audiences, "deep green," "lazy green," and "nongreen", and that each must be approached differently. Each will have different trigger points that will move them to buy, and for the nongreen audience, marketing effectively usually requires emphasizing product superiority rather than care for the planet.  On the other hand, Roper’s Green Gauge shows that a high percentage of consumers (42%) feel that environmental products don’t work as well as conventional ones. This is an unfortunate legacy from the 1970s when shower heads sputtered and natural detergents left clothes dingy. Given the choice, all but the greenest of customers will reach for synthetic detergents over the premium-priced, proverbial "Happy Planet" any day, including Earth Day. New reports, however show a growing trend towards green products.
The demand for green-oriented products has been a boom to the firms that supply them. New markets emerge for recycled building products, packaging, paper goods, and even sweaters and sneakers, as well as, more efficient appliances lighting, heating, and cooling systems in homes and offices. Some green options are more expensive than traditional products and initiatives. This could learn to exploitation which is common enough that it even had produced the term greenwashing. Consumers need to question whether a firm is spending significantly more money and time advertising being green and operating with consideration for the environment than actually spending these resources on environmentally sound practices.

Confusion

One challenge green marketers – old and new – are likely to face as green products and messages become more common is confusion in the marketplace. "Consumers do not really understand a lot about these issues, and there's a lot of confusion out there," says Jacquelyn Ottman (founder of J. Ottman Consulting and author of "Green Marketing: Opportunity for Innovation.") Marketers sometimes take advantage of this confusion, and purposely make false or exaggerated "green" claims. Critics refer to this practice as "green washing".

Greenwashing

Corporations are increasingly recognizing the benefits of green marketing, although there is often a thin line between doing so for its own benefit and for social responsibility reasons. The term “greenwashing” refers to all industries that adopt outwardly green acts with an underlying purpose to increase profits. The primary objective of greenwashing is to provide consumers with the feeling that the organization is taking the necessary steps to responsibly manage its ecological footprint. In reality, the company may be doing very little that is environmentally beneficial The term greenwashing was first used by environmentalist Jay Westerveld when objecting to hotelier's practice of placing notices in hotel rooms which asked their guests to reuse towels to “save the environment”. Westerveld noted that there was little else to suggest that the hoteliers were interested in reducing their environmental impacts, and that their interest in washing fewer towels seemed to be motivated by a concern to save costs rather than the environment. Since then greenwashing has become a central feature of debates about marketing communications and sustainability, with “awards” for greenwashing established and numerous campaigns, law and advice developed in an attempt to reduce or curb it.

Benefit corporations

In January 2012, Patagonia became the first brand to register for benefit corporation status.
A benefit corporation is an alternative to its standard counterpart as it operates under the legal premise of 1) creating a positive impact socially and environmentally in its materials, 2) uphold corporate social responsibility in terms of considering its workers, its community, and the environment as well as challenge its current boundaries in those areas, and 3) report its activity as a company as well as its achievements in social and environmental areas publicly using a non-partisan third party source.

Statistics

According to market researcher Mintel, about 12% of the U.S. population can be identified as True Greens, consumers who seek out and regularly buy so-called green products. Another 68% can be classified as Light Greens, consumers who buy green sometimes. "What chief marketing officers are always looking for is touch points with consumers, and this is just a big, big, big touch point that's not being served," says Mintel Research Director David Lockwood. "All the corporate executives that we talk to are extremely convinced that being able to make some sort of strong case about the environment is going to work down to their bottom line."

Adoptability

In 1989, 67 percent of Americans stated that they were willing to pay 5-10 percent more for ecologically compatible products. By 1991, environmentally conscious individuals were willing to pay between 15-20 percent more for green products. Today, more than one-third of Americans say they would pay a little extra for green products.
An important challenge facing marketers is to identify which consumers are willing to pay more for environmentally friendly products. It is apparent that an enhanced knowledge of the profile of this segment of consumers would be extremely useful.
Everett Rogers, communication scholar and author of “Diffusion of Innovations”, claims that the following five factors can help determine whether a new idea will be adopted or not, including the idealism of the shift towards “green”:
  1. Relative advantage: is the degree to which the new behavior is believed to accrue more beneficial outcomes than current practice.
  2. Observability: is how easy it is to witness the outcomes of the new behavior.
  3. Trialability: is the ease with which the new behavior can be tested by an individual without making a full commitment.
  4. Compatibility: is the degree to which the new behavior is consistent with current practice.
  5. Complexity: is how difficult the new behavior is to implement.

LOHAS

LOHAS stands for Lifestyles of Health and Sustainability, and describes an integrated, rapidly growing market for goods and services that appeal to consumers whose sense of environmental and social responsibility influences their purchase decisions. The Natural Marketing Institute’s (short: NMI) estimates the US LOHAS consumer market of products and services to be USD 209 billion – sold across all consumer segments.
The five LOHAS segments as defined by NMI include:
  • LOHAS: Active environmental stewards dedicated to personal and planetary health. These are the heaviest purchasers of green and socially responsible products and the early adopters who influence others heavily.
  • Naturalites: Motivated primarily by personal health considerations. They tend to purchase more LOHAS consumable products vs. durable items.
  • Drifters: While their intentions may be good, DRIFTERS follow trends when it is easy and affordable. They are currently quite engaged in green purchasing behaviours.
  • Conventionals: Pragmatists who embrace LOHAS behaviour when they believe they can make a difference, but are primarily focused on being very careful with their resources and doing the ‘right’ thing because it will save them money.
  • Unconcerned: Either unaware or unconcerned about the environment and societal issues mainly because they do not have the time or the means – these consumers are largely focused on getting by.

The green marketing mix

A model green marketing mix contains four "P's":
  • Product: A producer should offer ecological products which not only must not contaminate the environment but should protect it and even liquidate existing environmental damages.
  • Price: Prices for such products may be a little higher than conventional alternatives. But target groups like for example LOHAS are willing to pay extra for green products.
  • Place: A distribution logistics is of crucial importance; main focus is on ecological packaging. Marketing local and seasonal products e.g. vegetables from regional farms is more easy to be marketed “green” than products imported.
  • Promotion: A communication with the market should put stress on environmental aspects, for example that the company possesses a CP certificate or is ISO 14000 certified. This may be publicized to improve a firm’s image. Furthermore, the fact that a company spends expenditures on environmental protection should be advertised. Third, sponsoring the natural environment is also very important. And last but not least, ecological products will probably require special sales promotions.
Additional social marketing "P's" that are used in this process are:
  • Publics: Effective Social Marketing knows its audience, and can appeal to multiple groups of people. "Public" is the external and internal groups involved in the program. External publics include the target audience, secondary audiences, policymakers, and gatekeepers, while the internal publics are those who are involved in some way with either approval or implementation of the program.
  • Partnership: Most social change issues, including "green" initiatives, are too complex for one person or group to handle. Associating with other groups and initiatives to team up strengthens the chance of efficacy.
  • Policy: Social marketing programs can do well in motivating individual behavior change, but that is difficult to sustain unless the environment they're in supports that change for the long run. Often, policy change is needed, and media advocacy programs can be an effective complement to a social marketing program.
  • Purse Strings: How much will this strategic effort cost? Who is funding the effort?
The level of greening—strategic, quasi-strategic, or tactical—dictates what activities should be undertaken by a company. Strategic greening in one area may or may not be leveraged effectively in others. A firm could make substantial changes in production processes but opt not to leverage them by positioning itself as an environmental leader. So although strategic greening is not necessarily strategically integrated into all marketing activities, it is nevertheless strategic in the product area.

Ecolabels

An individual's belief that an environmental claim lacks honesty can have a negative effect on attitude toward a brand. If, on the other side, the consumer grants credibility to the claim, the individual will behave more respectfully toward the environment. The problem in extending that credibility to a brand is that consumers interested in ecological products generally are skeptical of commercial advertisements. This skepticism is due to various factors such as lack of language, the absence of scientific knowledge necessary to interpret advertising meaning, and, in particular, the falsehoods and exaggeration of some advertising techniques. To resolve this problem, independent organizations may choose to guarantee messages on the environmental benefits of brands with environmental labeling systems sponsored by independent organizations.

Life-cycle assessment

During the late 1980s, new instruments such as life-cycle assessment (LCA) were invented which allowed ecological considerations to be introduced into marketing decisions.
The life cycle assessment model seeks to identify the main types of environmental impact throughout the life cycle of a product. LCA was developed according to ISO 14040. The main goal of the LCA is to define the energy and environmental profile of the finished products. The reasons to use LCA arose from the need to have a precise process accounting and to highlight potential improvements that could be used in order to increase the environmental, energy and economic efficiency and overall effectiveness of the processes. In addition, the purpose was to quantify the environmental advantages deriving from the use of recycled raw material.

Example for LCA

LCA is used for example in the building sector. Buildings today account for the 40% of the world’s energy use. The resulting carbon emissions are substantially higher than those of the transportation sector. New buildings using more energy than necessary are being built every day, and millions of today's inefficient buildings will remain standing until at least 2050. It’s therefore necessary to start reducing energy use in new and existing buildings in order to reduce the planet's energy-related carbon footprint. Growing interest, space, and attention in the architecture sector are directed to environmental issues according to the principles of green building. Mineral, vegetable, or animal materials such as perlite, vermiculite, rock wool, glass wool, cork, plant fibers (cotton, flax, hemp, coconut), wood fiber, cellulose, and sheep's wool can be used for the production of insulation panels.

Cases

Phillips's "Marathon" CFL lightbulb

Philips Lighting's first shot at marketing a standalone compact fluorescent light (CFL) bulb was Earth Light, at $15 each versus 75 cents for incandescent bulbs. The product had difficulty climbing out of its deep green niche. The company re-launched the product as "Marathon," underscoring its new "super long life" positioning and promise of saving $26 in energy costs over its five-year lifetime. Finally, with the U.S. EPA's Energy Star label to add credibility as well as new sensitivity to rising utility costs and electricity shortages, sales climbed 12 percent in an otherwise flat market.

Car sharing services

Car-sharing services address the longer-term solutions to consumer needs for better fuel savings and fewer traffic tie-ups and parking nightmares, to complement the environmental benefit of more open space and reduction of greenhouse gases. They may be thought of as a "time-sharing" system for cars. Consumers who drive less than 7,500 miles a year and do not need a car for work can save thousands of dollars annually by joining one of the many services springing up, including Zipcar (East Coast), I-GO Car (Chicago), and Hour Car (Twin Cities).

Electronics sector

The consumer electronics sector provides room for using green marketing to attract new customers. One example of this is HP's promise to cut its global energy use 20 percent by the year 2010.[36] To accomplish this reduction below 2005 levels, The Hewlett-Packard Company announced plans to deliver energy-efficient products and services and institute energy-efficient operating practices in its facilities worldwide.

Products and services

Now companies are offering more eco-friendly alternatives for their customers. Recycled products for example, are one of the most popular alternatives that can benefit the environment. These benefits include sustainable forestry, clean air, energy efficiency, water conservation, and a healthy office. One example, is the E-commerce business and office supply company Shoplet which offers a web tool that allows you to replace similar items in your shopping cart with greener products.

Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Occasionally it is used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus. It is taken by mouth. It is also being used experimentally to treat COVID-19 as of 2020.

Common side effects include muscle problems, loss of appetite, diarrhea, and skin rash. Serious side effects include problems with vision, muscle damage, seizures, and low blood cell levels. It appears to be safe for use during pregnancy. Chloroquine is a member of the drug class 4-aminoquinoline. It works against the asexual form of malaria inside the red blood cell.

Chloroquine was discovered in 1934 by Hans Andersag. It is on the World Health Organization's List of Essential Medicines, the medicines needed in a health system that are considered to be the safest and most effective. It is available as a generic medication. The wholesale cost in the developing world is about US$0.04. In the United States, it costs about US$5.30 per dose.

Medical uses

Resochin tablet package

Malaria

Chloroquine has long been used in the treatment or prevention of malaria from Plasmodium vivax, P. ovale, and P. malariae, excluding the malaria parasite Plasmodium falciparum, for it started to develop widespread resistance to it.

Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations.

Amebiasis

In treatment of amoebic liver abscess, chloroquine may be used instead of or in addition to other medications in the event of failure of improvement with metronidazole or another nitroimidazole within 5 days or intolerance to metronidazole or a nitroimidazole.

Rheumatic disease

As it mildly suppresses the immune system, chloroquine is used in some autoimmune disorders, such as rheumatoid arthritis and lupus erythematosus.

Side effects

Side effects include blurred vision, nausea, vomiting, abdominal cramps, headache, diarrhea, swelling legs/ankles, shortness of breath, pale lips/nails/skin, muscle weakness, easy bruising/bleeding, hearing and mental problems. Other effects might include cardiovascular (rare), and blood reactions.
  • Seizures
    • Unwanted/uncontrolled movements (including tongue and face twitching) 
  • Deafness or tinnitus.
  • Nausea, vomiting, diarrhea, abdominal cramps, and anorexia
  • Headache.
  • Mental/mood changes (such as confusion, personality changes, unusual thoughts/behavior, depression, feeling being watched, hallucinating)
  • Signs of serious infection (such as high fever, severe chills, persistent sore throat)
  • Skin itchiness, skin color changes, hair loss, and skin rashes.
    • Chloroquine-induced itching is very common among black Africans (70%), but much less common in other races. It increases with age, and is so severe as to stop compliance with drug therapy. It is increased during malaria fever; its severity is correlated to the malaria parasite load in blood. Some evidence indicates it has a genetic basis and is related to chloroquine action with opiate receptors centrally or peripherally.
  • Unpleasant metallic taste
    • This could be avoided by "taste-masked and controlled release" formulations such as multiple emulsions.
  • Chloroquine retinopathy
    • May be irreversible. This occurs with long-term use over many years or with high doses. Patients on long-term chloroquine therapy should be screened at baseline and then annually after five years of use. Patients should be screened for vision changes such as blurring of vision, difficulty focusing, or seeing half an object.
  • Hypotension and electrocardiographic changes.
    • This manifests itself as either conduction disturbances (bundle-branch block, atrioventricular block) or Cardiomyopathy – often with hypertrophy, restrictive physiology, and congestive heart failure. The changes may be irreversible. Only two cases have been reported requiring heart transplantation, suggesting this particular risk is very low. Electron microscopy of cardiac biopsies show pathognomonic cytoplasmic inclusion bodies.
  • Pancytopenia, aplastic anemia, reversible agranulocytosis, low blood platelets, neutropenia.

Pregnancy

Chloroquine has not been shown to have any harmful effects on the fetus when used for malarial prophylaxis. Small amounts of chloroquine are excreted in the breast milk of lactating women. However, this drug can be safely prescribed to infants, the effects are not harmful. Studies with mice show that radioactively tagged chloroquine passed through the placenta rapidly and accumulated in the fetal eyes which remained present five months after the drug was cleared from the rest of the body. Women who are pregnant or planning on getting pregnant are still advised against traveling to malaria-risk regions.

Elderly

There is not enough evidence to determine whether chloroquine is safe to be given to people aged 65 and older. However, the drug is cleared by the kidneys and toxicity should be monitored carefully in people with poor kidney functions.

Drug interactions

  • Ampicillin- levels may be reduced by chloroquine
  • Antacids- may reduce absorption of chloroquine
  • Cimetidine- may inhibit metabolism of chloroquine; increasing levels of chloroquine in the body
  • Cyclosporine- levels may be increased by chloroquine
  • Kaolin- may reduce absorption of chloroquine
  • Mefloquine- may increase risk of convulsions

Overdose

Chloroquine is very dangerous in overdose. It is rapidly absorbed from the gut. In 1961, a published compilation of case reports contained accounts of three children who took overdoses and died within 2.5 hours of taking the drug. While the amount of the overdose was not stated, the therapeutic index for chloroquine is known to be small. Symptoms of overdose include headache, drowsiness, visual disturbances, nausea and vomiting, cardiovascular collapse, seizures, and sudden respiratory and cardiac arrest.
An analog of chloroquine – hydroxychloroquine – has a long half-life (32–56 days) in blood and a large volume of distribution (580–815 L/kg). The therapeutic, toxic and lethal ranges are usually considered to be 0.03 to 15 mg/l, 3.0 to 26 mg/l and 20 to 104 mg/l, respectively. However, nontoxic cases have been reported up to 39 mg/l, suggesting individual tolerance to this agent may be more variable than previously recognised.

Pharmacology

  • Absorption: Rapid and almost completely
  • Distribution: Widely distributed into body tissues
  • Protein binding: 55%
  • Metabolism: Partially hepatic to main metabolite, desethylchloroquine
  • Excretion: Urine (≥50% as unchanged drug); acidification of urine increases elimination
Chloroquine has a very high volume of distribution, as it diffuses into the body's adipose tissue. Chloroquine and related quinines have been associated with cases of retinal toxicity, particularly when provided at higher doses for longer times. Accumulation of the drug may result in deposits that can lead to blurred vision and blindness. With long-term doses, routine visits to an ophthalmologist are recommended.
Chloroquine is also a lysosomotropic agent, meaning it accumulates preferentially in the lysosomes of cells in the body. The pKa for the quinoline nitrogen of chloroquine is 8.5, meaning it is about 10% deprotonated at physiological pH as calculated by the Henderson-Hasselbalch equation. This decreases to about 0.2% at a lysosomal pH of 4.6. Because the deprotonated form is more membrane-permeable than the protonated form, a quantitative "trapping" of the compound in lysosomes results. (A quantitative treatment of this phenomenon involves the pKas of all nitrogens in the molecule; this treatment, however, suffices to show the principle.)
The lysosomotropic character of chloroquine is believed to account for much of its antimalarial activity; the drug concentrates in the acidic food vacuole of the parasite and interferes with essential processes. Its lysosomotropic properties further allow for its use for in vitro experiments pertaining to intracellular lipid related diseases, autophagy, and apoptosis.

Mechanism of action

Medical quinolines

Malaria

Hemozoin formation in P. falciparum: many antimalarials are strong inhibitors of hemozoin crystal growth.

Inside red blood cells, the malarial parasite, which is then in its asexual lifecycle stage, must degrade hemoglobin to acquire essential amino acids, which the parasite requires to construct its own protein and for energy metabolism. Digestion is carried out in a vacuole of the parasitic cell.
Hemoglobin is composed of a protein unit (digested by the parasite) and a heme unit (not used by the parasite). During this process, the parasite releases the toxic and soluble molecule heme. The heme moiety consists of a porphyrin ring called Fe(II)-protoporphyrin IX (FP). To avoid destruction by this molecule, the parasite biocrystallizes heme to form hemozoin, a nontoxic molecule. Hemozoin collects in the digestive vacuole as insoluble crystals.
Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated (to CQ2+), as the digestive vacuole is known to be acidic (pH 4.7); chloroquine then cannot leave by diffusion. Chloroquine caps hemozoin molecules to prevent further biocrystallization of heme, thus leading to heme buildup. Chloroquine binds to heme (or FP) to form the FP-chloroquine complex; this complex is highly toxic to the cell and disrupts membrane function. Action of the toxic FP-chloroquine and FP results in cell lysis and ultimately parasite cell autodigestion. Parasites that do not form hemozoin are therefore resistant to chloroquine.

Resistance in malaria

Since the first documentation of P. falciparum chloroquine resistance in the 1950s, resistant strains have appeared throughout East and West Africa, Southeast Asia, and South America. The effectiveness of chloroquine against P. falciparum has declined as resistant strains of the parasite evolved. They effectively neutralize the drug via a mechanism that drains chloroquine away from the digestive vacuole. Chloroquine-resistant cells efflux chloroquine at 40 times the rate of chloroquine-sensitive cells; the related mutations trace back to transmembrane proteins of the digestive vacuole, including sets of critical mutations in the P. falciparum chloroquine resistance transporter (PfCRT) gene. The mutated protein, but not the wild-type transporter, transports chloroquine when expressed in Xenopus oocytes (frog's eggs) and is thought to mediate chloroquine leak from its site of action in the digestive vacuole. Resistant parasites also frequently have mutated products of the ABC transporter P. falciparum multidrug resistance (PfMDR1) gene, although these mutations are thought to be of secondary importance compared to Pfcrt. Verapamil, a Ca2+ channel blocker, has been found to restore both the chloroquine concentration ability and sensitivity to this drug. Recently, an altered chloroquine-transporter protein CG2 of the parasite has been related to chloroquine resistance, but other mechanisms of resistance also appear to be involved. Research on the mechanism of chloroquine and how the parasite has acquired chloroquine resistance is still ongoing, as other mechanisms of resistance are likely.
Other agents which have been shown to reverse chloroquine resistance in malaria are chlorpheniramine, gefitinib, imatinib, tariquidar and zosuquidar.

Antiviral

Chloroquine has antiviral effects. It increases endosomal pH, resulting in impaired virus/cell fusion - fusion requires a low pH.
Chloroquine also seems to act as a zinc ionophore, thereby allowing extra cellular zinc to enter inside the cell and inhibit viral RNA dependant RNA polymerase.

Other

Chloroquine inhibits thiamine uptake. It acts specifically on the transporter SLC19A3.
Against rheumatoid arthritis, it operates by inhibiting lymphocyte proliferation, phospholipase A2, antigen presentation in dendritic cells, release of enzymes from lysosomes, release of reactive oxygen species from macrophages, and production of IL-1.

History

In Peru the indigenous people extracted the bark of the Cinchona plant trees and used the extract (Chinchona officinalis) to fight chills and fever in the seventeenth century. In 1633 this herbal medicine was introduced in Europe, where it was given the same use and also began to be used against malaria. The quinoline antimalarial drug quinine was isolated from the extract in 1820, and chloroquine is an analogue of this.
Chloroquine was discovered in 1934 by Hans Andersag and coworkers at the Bayer laboratories, who named it "Resochin". It was ignored for a decade, because it was considered too toxic for human use. During World War II, United States government-sponsored clinical trials for antimalarial drug development showed unequivocally that chloroquine has a significant therapeutic value as an antimalarial drug. It was introduced into clinical practice in 1947 for the prophylactic treatment of malaria.

Names

Brand names include Chloroquine FNA, Resochin, Dawaquin, and Lariago.

Research

COVID-19

In late January 2020 during the 2019–20 coronavirus outbreak, Chinese medical researchers stated that exploratory research into chloroquine and two other medications, remdesivir and lopinavir/ritonavir, seemed to have "fairly good inhibitory effects" on the SARS-CoV-2 virus, which is the virus that causes COVID-19. Requests to start clinical testing were submitted.
Chloroquine had been also proposed as a treatment for SARS, with in vitro tests inhibiting the SARS-CoV virus.

On 19 February 2020, preliminary results found that chloroquine may be effective and safe in treating COVID-19 associated pneumonia. The Guangdong Provincial Department of Science and Technology and the Guangdong Provincial Health and Health Commission issued a report stating that chloroquine phosphate "improves the success rate of treatment and shortens the length of patient’s hospital stay" and recommended it for people diagnosed with mild, moderate and severe cases of novel coronavirus pneumonia.
Chloroquine has been recommended by Chinese, South Korean and Italian health authorities for the treatment of COVID-19. These agencies noted contraindications for people with heart disease or diabetes. In February 2020, both drugs were shown to effectively inhibit COVID-19 in vitro, but a further study concluded that hydroxychloroquine was more potent than chloroquine, with a more tolerable safety profile. Preliminary results from a trial suggested that chloroquine is effective and safe in COVID-19 pneumonia, "improving lung imaging findings, promoting a virus-negative conversion, and shortening the disease course."

Other viruses

In October 2004 a group of researchers at the Rega Institute for Medical Research published a report on chloroquine, stating that chloroquine acts as an effective inhibitor of the replication of the severe acute respiratory syndrome coronavirus (SARS-CoV) in vitro.
Chloroquine is being considered in pre-clinical models as a potential agent against chikungunya fever.

Other

The radiosensitizing and chemosensitizing properties of chloroquine are beginning to be exploited in anticancer strategies in humans. In biomedicinal science, chloroquine is used for in vitro experiments to inhibit lysosomal degradation of protein products.
