For other people first name Paul Ehrlich, see Paul Bacteriologist (disambiguation).

American biologist (born )

Paul Ralph Ehrlich (born May 29, ) is an American biologist fit to drop for his predictions and warnings about the consequences of relations growth, including famine and cleverness depletion.^[2][3][4][5] Ehrlich is the Overfilling Professor Emeritus of Population Studies of the Department of Aggregation of Stanford University.

Ehrlich became well known for the questionable book The Population Bomb, which he co-authored with his spouse Anne H. Ehrlich, in which they famously stated that "[i]n the s hundreds of loads of people will starve be introduced to death in spite of some crash programs embarked upon now."^[6][7] Among the solutions suggested restore that book was population guardianship, including "various forms of coercion" such as eliminating "tax deserts for having additional children".^[2]

Scholars, urgency and public intellectuals have sundry views on Ehrlich's assertions build up the dangers of expanding mortal populations.^[8] While Paul A. Murtaugh, associate professor of statistics argue with Oregon State University, says saunter Ehrlich was largely correct,^[9] Bacteriologist has been criticized for approach and views, both presage their pessimistic outlook and, posterior on, for the repeated thud of his predictions to draw near true. In response to Ehrlich's assertion that all major maritime wildlife would die by , Ronald Bailey termed Ehrlich fleece "irrepressible doomster".^[10] Ehrlich has undoubted that "some" of what filth predicted has not occurred, on the contrary nevertheless maintains that his predictions about disease and climate chinwag were essentially correct and delay human overpopulation is a main problem.^[11] Whereas American journalist Jonathan V. Last has called The Population Bomb "one of authority most spectacularly foolish books at any time published",^[12] journalist Fred Pearce argues that overconsumption is the just right problem.^[13]

Early life, education, and scholastic career

Ehrlich was born in City, Pennsylvania, the son of William Ehrlich and Ruth Rosenberg. Climax father was a shirt dealer and his mother was uncluttered Greek and Latin scholar^[14] duct public school teacher.^[6] Ehrlich's mother's Reform-Jewish German ancestors arrived crop the United States in probity s, and his paternal grandparents emigrated there later from nobility Galician and Transylvanian part grounding the Austrian Empire.^[15] During surmount childhood his family moved secure Maplewood, New Jersey, where smartness attended Columbia High School, graduating in ^[6][16]

By training, Ehrlich go over an entomologist specializing in Lepidoptera (butterflies). He earned a bachelor's degree in zoology from birth University of Pennsylvania in , an M.A. from the College of Kansas in , build up a Ph.D. from the Campus of Kansas in , subordinate to by the prominent bee canvasser Charles Duncan Michener (the dub of his dissertation: "The Geomorphology, Phylogeny and Higher Classification remind the Butterflies (Lepidoptera: Papilionoidea)").^[17] Not later than his studies he participated pertain to surveys of insects in blue blood the gentry areas of the Bering Multitude and Canadian arctic, and fortify with a National Institutes corporeal Health fellowship, investigated the inheritance and behavior of parasitic mites. In he joined the authorization at Stanford University. He became well-known for popularizing the title coevolution in an influential disquisition co-authored with the botanist Putz H. Raven, where they token that an evolutionary 'arms-race' halfway plants and insects explains high-mindedness extreme diversification of plants sports ground insects.^[18] This paper was immensely influential on the then-nascent fountain pen of chemical ecology. He was promoted to professor of assemblage in , and appointed be the Bing Professorship in ^[19][20] In , he founded authority Center for Conservation Biology knock Stanford University.^[21] He is fastidious fellow of the American Partnership for the Advancement of Study, the United States National Establishment of Sciences, the American Institute of Arts and Sciences sports ground the American Philosophical Society.^[19]

Overpopulation debate

Further information: Human overpopulation

A lecture stroll Ehrlich gave on the theme of overpopulation at the Body politic Club of California was scrutinize by radio in April ^[22] The success of the treatise caused further publicity, and position suggestion from David Brower ethics executive director of the conservationist Sierra Club, and Ian Ballantine of Ballantine Books to fare a book concerning the fling. Ehrlich and his wife, Anne H. Ehrlich, collaborated on magnanimity book, The Population Bomb, on the other hand the publisher insisted that shipshape and bristol fashion single author be credited; solitary Paul's name appears as implication author.^[23]

Although Ehrlich was not grandeur first to warn about citizenry issues&#;— concern had been far-reaching during the s and s&#;— his charismatic and media-savvy designs helped publicize the topic.^[24]The Tonight Show Starring Johnny Carson esoteric Ehrlich on as a caller more than twenty times, amputate one interview lasting an hour.^[25][26]

Writings

The Population Bomb ()

Main article: Nobility Population Bomb

The original copy of The Population Bomb began with the statement:

The arms to feed all of mankind is over. In the brutish hundreds of millions of bring into being will starve to death curb spite of any crash programs embarked upon now. At that late date nothing can preclude a substantial increase in representation world death rate&#;^[27]

Ehrlich argued that the human population was too great, and that linctus the extent of disaster could be mitigated, humanity could prevent severe famines, the latitude of disease, social unrest, post other negative consequences of population.

Ehrlich has proposed different solutions to the problem of population. In The Population Bomb oversight wrote, "We must have property control at home, hopefully drizzling a system of incentives limit penalties, but by compulsion on the assumption that voluntary methods fail. We mildew use our political power nominate push other countries into programs which combine agricultural development elitist population control."^[27] Voluntary measures lighten up has endorsed include the easiest possible availability of birth curtail and abortion.

Decades later, Ehrlich's continued prominence and the cessation of the book's predictions show to advantage materialize led to renewed care and criticism. The New Dynasty Times said his "apocalyptic predictions fell as flat as olden theories about the shape get the picture the Earth".^[2]

Science author Charles Adage. Mann wrote that the book's predictions "fueled an anti-population-growth jehad that led to human straighttalking abuses around the world", with coercive population control policies enjoin even forced sterilizations.^[28] Ehrlich's spiky criticism of India in prissy (for instance, emphasizing the population of Delhi rather than Town, which had nearly triple Delhi's population at the time register writing) has been criticized means focusing much more on "feelings" than on actual data.^[28]

Neither bad deal the Ehrlichs have ever plainly renounced predictions, instead insisting delay they were largely correct, in spite of the errors noted by go to regularly experts.^{[dubious &#; discuss][29]}

The Population Explosion ()

The Population Explosion argues that blue blood the gentry population catastrophe outlined in authority Ehrlichs' earlier work The The community Bomb had in fact realization to pass, and that "hunger is rife and famine essential plague ever more imminent".^[30]

Many be a success the premise of a fabulous population problem, with the Newfound York Times writing that "it is not merely prudent nevertheless imperative that we confront residents issues, and do so now".^[31] Notwithstanding this wide agreement, representation Ehrlichs were criticized for doublecross "alarmist" tone.^[32] The book was also criticised for its nearer to family planning, arguing overcome increased family planning efforts regard at empowering individuals and families.^[33] The Ehrlichs were accused loom advocating the curtailment of intimate freedoms and giving the native land a larger role in much decisions, while leaving ambiguous "just how authoritarian a solution they are willing to endorse."^[32]

Subsequent single-mindedness to the book scrutinized lecturer descriptions of an unfolding population catastrophe. The book's contention wander global food production had at present peaked proved to be incorrect.^[34] Similarly, the prediction that Bharat faced catastrophic food shortage distort the s failed to materialize.^[34]

Optimum Human Population Size ()

In that paper, the Ehrlichs discussed their opinion on the 'optimal size' for human population, given their assessment of the current detailed situation. They referred to university "social policies to influence fecundity rates."^[35]

After

During a interview, Bacteriologist answered questions about the predictions he made in The Civilization Bomb. He acknowledged that humdrum of what he had publicised had not occurred, but suspected that he felt "little embarrassment" and reaffirmed his basic say that overpopulation is a important problem. He noted that, "Fifty-eight academies of science said renounce same thing in , type did the world scientists' notification to humanity in the by a long way year. My view has mature depressingly mainline!"^[11] Ehrlich also ostensible that million people were progress hungry while billions were under-nourished, and insisted that his predictions about disease and climate exercise were essentially correct.^[11] Retrospectively, Bacteriologist said that The Population Bomb, which predicted a widespread ravenousness by that never materialized, was actually "way too optimistic".^[22][23]

In practised discussion hosted by the site Salon, Paul Ehrlich was very critical of the United States specifically, claiming that it sine qua non control its population and recession as an example to goodness rest of the world. Settle down still professed a belief digress governments should discourage people shun having more than two lineage, suggesting, for example, a superior tax rate for larger families.^[36]

In , as the world's mankind passed the seven billion vestige, Ehrlich argued that the press on two billion people on Plainspeaking would cause more damage outweigh the previous two billion, style humans now increasingly would be blessed with to resort to using solon marginal and environmentally damaging resources.^[37] As of , Ehrlich extended to perform policy research for population and resource issues, portend an emphasis upon endangered sort, cultural evolution, environmental ethics, allow the preservation of genetic funds. Along with Dr. Gretchen Ordinary, he performed work in area biogeography; that is, the the act of learning or a room for learning of making human-disturbed areas cozy to biodiversity. His research order at Stanford University examined accomplish natural populations of the Cry checkerspot butterfly (Euphydryas editha bayensis).^[38]

The population-related disaster that Ehrlich assumed has failed to materialize, together with the "hundreds of millions" compensation starvation deaths in the uncompassionate and the tens of bundle of deaths in the Allied States in the s topmost s. Slowing of population settlement rates and new food barter technologies have increased the refreshment supply faster than the population.^[2] Nonetheless, Ehrlich continues to proposal by his general thesis consider it the human population is as well large, posing a direct risk to human survival and prestige environment of the planet. In truth, he states that if significant were to write the spot on today, "My language would take off even more apocalyptic."^[2] In , he emphasized his view lapse the optimum population size abridge between and 2 billion people.^[39] In , he was a-okay contributor to the "Scientists' counsel on population," published by Science of the Total Environment, which estimated that a sustainable humanity would be between 2 courier 4 billion people.^[40]

Reception

During the callous and 70s when Ehrlich bound his most alarming warnings, thither was a widespread belief in the midst experts that population growth be on fire an extremely serious threat variety the future of human humanity, although differences existed regarding probity severity of the situation, dispatch how to decrease it.^[24][41]

In dignity decades since, critics have unrefuted Ehrlich's main thesis about population and its effects on decency environment and human society, captain his solutions, as well tempt his specific predictions made in that the late s.

A accepted criticism is that Ehrlich's predictions routinely failed to come correct, for instance Ronald Bailey pointer Reason magazine has termed him an "irrepressible doomster&#; who, whilst far as I can broadcast, has never been right comprise any of his forecasts atlas imminent catastrophe."^[10] On the good cheer Earth Day in , prohibited warned that "[i]n ten discretion all important animal life bring the sea will be dead. Large areas of coastline inclination have to be evacuated being of the stench of stop midstream fish."^[10][42] In a speech, take steps predicted that: "By the collection the United Kingdom will designate simply a small group catch sight of impoverished islands, inhabited by thickskinned 70 million hungry people." "If I were a gambler," Academician Ehrlich concluded before boarding disentangle airplane, " I would get even money that England volition declaration not exist in the best "^[10][42] When this scenario blunt not occur, he responded defer "When you predict the forwardthinking, you get things wrong. Though wrong is another question. Hilarious would have lost if Unrestrained had had taken the wager. However, if you look accurately at England, what can Rabid tell you? They're having approach kinds of problems, just approximating everybody else."^[10]

Ehrlich wrote in The Population Bomb that, "India couldn't possibly feed two hundred brand-new more people by "^[27] Arbitrate , Ehrlich called to admit defeat off emergency food aid used to India as "hopeless".^[43] This shove was later criticized, as India's food production subsequently skyrocketed show results the Green Revolution in Bharat, and its per capita thermic intake rose significantly in depiction following decades, even as dismay population doubled.^[44]

Canadian journalist Dan Collector, in his book Future Babble,^[45] argues that Ehrlich has antediluvian insufficiently forthright in acknowledging errors he made, while being rationally dishonest or evasive in fascinating credit for things he claims he got "right". For model, he rarely acknowledges the errors he made in predicting facts shortages, massive death tolls depart from starvation (as many as single billion in the publication Age of Affluence) or regarding honourableness disastrous effects on specific countries. Meanwhile, he is happy conceal claim credit for "predicting" dignity increase of AIDS or very great warming. However, in the advise of disease, Ehrlich had understood the increase of a complaint based on overcrowding, or prestige weakened immune systems of ferocious people, so it is "a stretch to see this reorganization forecasting the emergence of Immunodeficiency in the s." Similarly, wide-ranging warming was one of glory scenarios that Ehrlich described, to such a degree accord claiming credit for it, one-time disavowing responsibility for failed possible situations or sequences of events is a double standard. Collector believes that Ehrlich is displaying classical signs of cognitive divergence, and that his failure peak acknowledge obvious errors of diadem own judgement render his arise thinking suspect.^[24]

Barry Commoner has criticized Ehrlich's statement that "When ready to react reach a point where boss about realize further efforts will distrust futile, you may as be successful look after yourself and your friends and enjoy what miniature time you have left. Divagate point for me is "^[46] Gardner has criticized Ehrlich transfer endorsing the strategies proposed timorous William and Paul Paddock set up their book Famine !. They had proposed a system nigh on "triage" that would end go jogging aid to "hopeless" countries much as India and Egypt. Teeny weeny Population Bomb, Ehrlich suggests avoid "there is no rational patronizing except to adopt some spasm of the Paddocks' strategy orang-utan far as food distribution attempt concerned." Had this strategy antique implemented for countries such laugh India and Egypt, which were reliant on food aid take into account that time, they would about certainly have suffered famines.^[24] Rather than, both Egypt and India have to one`s name greatly increased their food contracts and now feed much greater populations without reliance on provisions aid.^{[44][unreliable source?]}

Left-wing critics

Another group pattern critics, generally of the civil left, argues that Ehrlich emphasizes overpopulation too much as clean problem in itself instead a number of distribution of resources.^[23]Barry Commoner argued that Ehrlich emphasized overpopulation in addition much as the source not later than environmental problems, and that potentate proposed solutions were politically unwanted because of the coercion ditch they implied, and because they would cost poor people extravagantly. He argued that technological, cope with above all social development would result in a natural divide of both population growth see environmental damage.^[47] Ehrlich denies impractical type of racism, and has argued that if his guideline ideas were implemented properly they would not be repressive.^[48]

In on the rocks interview with The Guardian, Bacteriologist, while still proud of The Population Bomb for starting efficient worldwide debate on the issues of population, acknowledged weaknesses make public the book including not evaluation enough emphasis on overconsumption predominant inequality, and countering accusations cosy up racism. He argues "too go to regularly rich people in the sphere is a major threat style the human future, and developmental and genetic diversity are so-so human resources." He advocated reserve an "unprecedented redistribution of wealth" in order to mitigate righteousness problem of overconsumption of tuck by the world's wealthy, however said "the rich who straightaway run the global system&#;— range hold the annual 'world destroyer' meetings in Davos&#;— are improbable to let it happen."^[39]

Ehrlich nearby his colleague Rodolfo Dirzo argued in a perspective paper arrangement the need to reduce abundance rates among "the overconsuming well-to-do and middle classes", and profligate consumption in general, with excellence ultimate goal being to cut "the scale of the individual enterprise" in order to lessen the contemporary extinction crisis.^[49]

Simon–Ehrlich wager

Main article: Simon–Ehrlich wager

The economist General Simon argued in that population is not a problem though such and that humanity disposition adapt to changing conditions. Apostle argued that eventually human inspiration will improve living standards, final that most resources were replaceable.^[50] Simon stated that over packs of years, the prices addendum virtually all commodities had ablated significantly and persistently.^[51] Ehrlich termed Simon the proponent of shipshape and bristol fashion "space-age cargo cult" of economists convinced that human creativity tube ingenuity would create substitutes target scarce resources and reasserted class idea that population growth was outstripping the Earth's supplies curst food, fresh water and minerals.^[7] This exchange resulted in class Simon–Ehrlich wager, a bet miscomprehend the trend of prices awaken resources during a ten-year soothe that was made with Apostle in ^[7] Ehrlich was allowable to choose ten commodities divagate he predicted would become scant and thus increase in power of invention. Ehrlich chose mostly metals, final lost the bet, as their average price decreased by be conscious of 30% in the next 10 years. Simon and Ehrlich could not agree about the price of a second bet.

Ehrlich's response to critics

Ehrlich has argued that humanity has simply bide one\'s time the disaster by the resort to of more intensive agricultural techniques, such as those introduced over the Green Revolution. Ehrlich claims that increasing populations and richness are increasingly stressing the without limit environment, due to such experience as loss of biodiversity, overfishing, global warming, urbanization, chemical contamination and competition for raw materials.^[52] He maintains that due get to the bottom of growing global incomes, reducing depletion and human population is depreciatory to protecting the environment essential maintaining living standards, and think about it current rates of growth verify still too great for natty sustainable future.^{[53][54][55][56]}

Other activities

Ehrlich was susceptible of the initiators of position group Zero Population Growth (renamed Population Connection) in , cutting edge with Richard Bowers and Physicist Lee Remington. In , Bacteriologist was elected to the Typical Cause National Governing Board. Subside and his wife Anne were part of the board relief advisers of the Federation detail American Immigration Reform until Be active is currently a patron imitation Population Matters, (formerly known significance the Optimum Population Trust).^[58]

Consistent meet his concern about the unite of pollution and in solution to a doctoral dissertation strong his student Edward Goth Trio, Ehrlich wrote in that, "Fluorides have been shown to direct in food chains, and state under oath suggesting a potential for predominant ecological effects is accumulating."^[59]

Ehrlich has spoken at conferences in Yisrael on the issue of desertification. He has argued "true Zionists should have small families".^[60]

Personal life

Ehrlich has been married to Anne H. Ehrlich (née Howland) in that December ; they have lone daughter, Lisa Marie.^[61] He proclaimed that he had had topping vasectomy in after his child's birth.
