george masters woodwell (october 23, 1928   june 18, 2024) was an american ecologist. he founded several programs in ecology, first at brookhaven national laboratory then at the marine biological laboratory in woods hole, massachusetts, and then at the woods hole research center, now known as woodwell climate research center, which he founded in 1985. he is best known for his work on the effects of ionizing radiation on forest ecosystems, his work to have the pesticide ddt banned from use in the united states, and his work to call attention to the threat of climate change as a result of combustion of fossil fuels. woodwell was one of the first scientists to sound the alarm about climate change, testifying before congress about climate change impacts in 1986. he was a founding board member of the environmental defense fund and the natural resources defense council. woodwell was born in cambridge, massachusetts to parents who were educators: philip mcintire woodwell and virginia sellers. he spent his childhood summers on his family farm in maine.[1] he attended the boston latin school.[2][3] he received a bachelor's degree in biology in 1950 from dartmouth college. he served as a lt. (j.g.) in the united states navy from 1950 to 1953. he held a master's degree and a phd in botany from duke university which he received in 1958.[1] after completing his phd, woodwell became a professor of botany at the university of maine. he taught there for three years.[4] in 1961, woodwell began working at brookhaven national laboratory. in a seminal experiment at brookhaven, woodwell placed a source of ionizing gamma radiation (cesium 137, 9500 curies)[5] at the center of an oak pine forest and, over the course of ten years, documented the changes in structure and function of the forest plants. he concluded what is now widely accepted, that organisms with the most sophisticated structure will die first when exposed to chronic stress. simpler organisms are more resilient to chronic stress. he extrapolated to posit that the results he found in the long island forest ecosystem were also true of the global ecosystem: that natural systems will degrade in a predictable pattern when exposed to chronic stress.[6][4][7] woodwell's research on pesticides focused on ddt where he and fellow scientists were among the first to warn of the harmful effects of ddt on wildlife. that work helped lead to a ban on the use of ddt in the us. it was this group of scientists and lawyers who established the environmental defense fund in 1967 as a result of their work on ddt.[4][1] woodwell conducted extensive research on carbon budgeting in north american forests and estuaries.[3] he was among the first to recognize that climate change created a positive feedback system: that the warming fed the warming, threatening an increase in the pace of climate change over time. in 1972, woodwell held a conference, titled carbon and the biosphere, at brookhaven with over 50 biologists, climatologists, and oceanographers. it was the first international gathering to directly address climate change. in 1979, the carter administration asked woodwell and four other scientists to create a report on the ecological impact of rising atmospheric carbon dioxide. according to james gustave speth, then chairman of the white house council on environmental quality, “the report predicted ‘a warming that will probably be conspicuous within the next 20 years,’ and it called for early action."[1] in 1970, woodwell was a founding board member of the natural resources defense council. in 1982, woodwell helped found the world resources institute.[1] in 1975, woodwell started the ecosystems center at the woods hole marine biological laboratory.[7] in 1985, woodwell founded the woods hole research center.[1] he and his staff were instrumental in producing the framework convention on climate change in 1992, which was approved by 92 countries at the rio climate summit.[8] in 1986, woodwell testified before congress about climate change impacts.[9][10] it was the first ever congressional hearing on climate change. his testimony detailed the threat of global permafrost thaw and the importance of forests.[7] woodwell and his wife katharine had four children together.[1] he died at his home in woods hole, massachusetts, on june 18, 2024, at the age of 95.[7] woodwell was made a member of the american academy of arts and sciences in 1980[11] and a member of the national academy of sciences in 1990.[1] in 1997, woodwell was awarded the 3rd annual heinz award in the environment,[12] and in 2001, he was awarded the volvo environment prize.[13] in 2020, the woods hole research center was renamed to the woodwell climate research center to honor woodwell and to emphasize the scientific focus on climate change.[14]

george m. woodwell is the founder and president emeritus of the woods hole research center. (photo: steve curwood) ecologist george woodwell has decades of research and environmental action under his belt, from documenting the dangers of ddt and climate change to founding the woods hole research center helping start other key organizations including the environmental defense fund, the natural resources defense council and the world resources institute. his new book, “a world to live in,” offers a reflection on the dangers of exceeding the planet’s biophysical limits. speaking with living on earth host steve curwood he shared some lessons he has learned about nature and environmental policy. curwood: it’s living on earth. i’m steve curwood. few scientists have as stellar record in environmental science or policy as george m. woodwell. when he won the $200,000 volvo environmental prize in 2001, the citation mentioned that in the1960’s dr. woodwell was among the first to investigate the health effects of radioactivity, followed by groundbreaking research that ultimately led to america's ban on ddt. this unassuming biologist was part of a team who documented climate change for president jimmy carter in the 1970’s. a world to live in makes a case for how the health of the biosphere is closely linked with humanity’s future. (photo: mit press) dr. woodwell helped found the environmental defense fund, the natural resources defense council, and the world resources institute. he’s also the founder, president, and director emeritus of the woods hole research center, which documents how forests affect global climate and delivered seminal work that led to the un framework convention on climate change. george woodwell’s latest book is called “a world to live in”. when i visited him in woods hole, massachusetts, he told me that’s an increasing challenge. woodwell: well, the world is literally falling apart. we have reached a point where the opportunities for experimentation with politics and with economics, the two big systems that we admire and use and have developed to a high degree are limited    they are limited by the biophysical limits of the earth and that topic    the biophysics of the earth is a topic that i have pursued for my whole career and it’s perfectly conspicuous where those limits are becoming important. curwood: reflecting on his career, george woodwell told me about some of his earliest research into the pesticide ddt. woodwell: ddt is a persistent pesticide. it was hailed as the ultimate pesticide in the postwar years when it was first released for general use. we showed in long island that the food web there was contaminated from the water of the marshes right on through the life of the marshes, clams, birds, and every trophic level existing at that time in the middle 1960s, had a burden of ddt residues coming from the aerial spraying of salt marshes to control the salt marsh mosquitoes within a factor of 10 of the acute lethal level for that organism. that sounds as though it's safe enough but the concentration up that food web was enormous. the concentration factors ran up to a hundred thousand fold. as a result of that we did get a court order which in the end resulted in the abandonment of ddt for use in spraying the salt marshes, and ultimately it led to the development of environmental defense fund and the abandonment of ddt for general use in united states which was a wise thing. curwood: your book paints corporations and industry interests as bearing the brunt of blame for environmental havoc through the decades. what kinds of events have shaped this perspective? the natural landscape of woods hole, massachusetts, a neighborhood in the town of falmouth where woodwell founded the woods hole research center in 1985. (photo: bill llott, flickr cc by nc nd 2.0) woodwell: well, industries feel as though, in fact say commonly, that their purpose is financial profit at whatever cost. and they've made the assumption that cost can legitimately be pushed into the public realm. i look at this these days in a world of 7 billion people, pushing all the biophysical limits of the earth, and say, “well, let's look at industries and ask just what their purpose is.” there is no industry that doesn't claim that it's doing something that's useful to the public in general, that they are selling a useful good of some sort, and in the process they're making a profit, but the profits get put first. fiduciary responsibilities get talked about as being preeminent. well, that’s ridiculous. it's absolutely not possible to have a tight world of seven billion or more people who are growing into demands, further demands, on resources all the time by developing technologies that make it possible to exploit bigger pieces of the resources available, all of those competing with one another, and turn these industries loose to do that. curwood: so, you discuss in your book what the various presidencies throughout the years have meant for the climate. so which presidents have been the best in your view? which have been the worst when it comes to climate change policy? woodwell: oh, my. (chuckles) well, clinton had the greatest opportunities. actually, carter was the very best. he understood the problem. he did things about it. he put solar panels on the roof of white house, and he developed the solar energy research institute, and he was very astute and intellectually engaged. and if he had continued, if he had not been displaced by a conservative president, mr. reagan, who abhored anything to do with science and with the climatic disruption, we would have been 30 years ahead of where we are now. host/executive producer steve curwood and ecologist george woodwell at the woods hole research center in massachusetts. (photo: steve curwood) curwood: and in your view the worst president in terms of climate? perhaps you’re suggesting president reagan, then. woodwell: (chuckles.) well, the transition that reagan made, of course, was important, but the presidents who followed him had to go out of their way to do anything really constructive. and, when al gore was asked to take a vigorous stand on the climate issue while he was in office, he said, “hmmm, you want me to commit political suicide?” things had degenerated to that point. curwood: so, let's talk about today. what do you think a trump presidency would mean for the climate? woodwell: that's a fairly simple question. i don't think mr. trump has the slightest idea as to how environment limits economic and political aspirations or human aspirations, and i just don't really care to speculate as to just how bad he would be. curwood: and, in your view, what would happen if hillary clinton makes it to the white house? woodwell: hillary is very well informed on virtually every topic. my guess is that hilary will rise to the challenge. she'll be under enormous pressure from elements of the scientific community that are well seated in the conservation law groups. the scientific community should be up in arms against the present attitude, that we can double the warming of the earth that we've experienced so far and do it safely by going to two degrees change instead of one degree change in the mean temperature of the earth as a whole. curwood: on page 100 of your book, george, you say that no threat has been great enough for the nations of the world to come together on climate change. how does the paris climate agreement measure up to that challenge, in your opinion? woodwell speaking at the tavern club in boston at an event honoring the release of his book. (photo: steve curwood) woodwell: well, i think the paris climate agreement is a political and economic compromise. i think the scientific community should not have accepted that and should be up in arms at the moment, saying, “it cannot work. it will not work. it cannot work, and it cannot be allowed.” the only course at the moment is to make the transition from fossil fuels to renewable energy sources, a perfectly attractive and possible and financially attractive, lucrative transition. it's not a dream, but it is a dream world. it’s a world that everyone would like to live in, and it's a clean world in which human rights are protected, the common property resources of air, water, and land are cherished and defended, and industries have a purpose, a primary purpose, which is the quality of the public realm. curwood: george woodwell, of all the things you've worked on over the past years, what do you feel was the most important? where do you feel you really made the biggest difference? woodwell: well, i'm not sure i've made any difference, but i've been very fortunate to work on a series of topics which have turned out to be great issues of environment. so, to the extent that the public realizes that they are great issues and that correcting them, turning them to human advantage requires fundamental changes in how we manage the world, and the responsibility for that is a core purpose of government. governments forget. in their enthusiasm for developing economic goods they forget that they have a fundamental responsibility to protect ecological integrity, and to the extent that the public realizes that i think we've made a contribution. i'm not sure that the intensity with which the public can realize that is going to be great enough to correct the trends at the moment, which any ecologist sees as thoroughly threatening. curwood: george woodwell’s new book is called “a world to live in.” he’s the director emeritus of the woods hole research center. thank you so much for taking the time with us today, dr. woodwell. woodwell: well, i'm delighted, always delighted to talk about these matters. about george m. woodwell the 2001 volvo environmental prize citation for george m. woodwell the heinz award citation for george m. woodwell a world to live in living on earth 62 calef highway, suite 212 lee, nh 03861 telephone: 617 287 4121 e mail: comments@loe.org donate to living on earth!living on earth is an independent media program and relies entirely on contributions from listeners and institutions supporting public service. please donate now to preserve an independent environmental voice. newsletterliving on earth offers a weekly delivery of the show's rundown to your mailbox. sign up for our newsletter today! sailors for the sea: be the change you want to sea. the grantham foundation for the protection of the environment: committed to protecting and improving the health of the global environment. contribute to living on earth and receive, as our gift to you, an archival print of one of mark seth lender's extraordinary wildlife photographs. follow the link to see mark's current collection of photographs. buy a signed copy of mark seth lender's book smeagull the seagull & support living on earth © copyright world media foundation. all rights reserved home | contact | rss | donate | newsletter

falmouth, ma   wed, june 19th  with deep sadness, woodwell climate research center announces the passing of dr. george masters woodwell, a pioneer and visionary in the field of climate science, beloved family member, friend, and mentor, and founder and director emeritus of our center. he passed away on tuesday, june 18, 2024 surrounded by his family. he was 95. woodwell dedicated his career to ecological research, and to uplifting science to inform critical global policy and urgently needed solutions to some of the biggest environmental issues of the late twentieth century making enormous contributions to the world through his work of scientific understanding, environmental sustainability, and climate stability. at a time when the biological sciences were increasingly focused on the molecular and cellular level, dr. woodwell was steadfast in his belief that ecosystem level understanding was critical. he started and led ecological research programs within the university of maine, brookhaven national laboratory, and the marine biological laboratory. he worked tirelessly to bring science into the public discourse. based on his research demonstrating the damaging effects of the pesticide ddt, he was a strong scientific voice in the push to ban it. he conducted groundbreaking research on the ecological effects of nuclear radiation. ultimately, he turned his attention to what was at the time known as “the carbon dioxide problem.” he provided prescience testimony at the first congressional hearing on climate change in 1986, highlighting issues the global ramifications of arctic warming and the importance of forests in the climate system that have been enduring pillars of climate research since. dr. woodwell also played an outsized role in building today’s ecosystem of science based advocacy and policymaking, helping found preeminent environmental non profits including environmental defense fund, natural resources defense council, and world resources institute. additionally, dr. woodwell was a former chairman of the board of trustees of the world wildlife fund us, and former president of the ecological society of america. he saw the need for international policy and governance to address climate change, guided by global scientific expertise, and played important roles in the creation of what became the intergovernmental panel on climate change, which was recognized in 2007 with a nobel peace prize, and the united nations framework convention on climate change the treaty that has driven and guided international climate negotiations for more than thirty years. in 1985, he founded the woods hole research center renamed woodwell climate research center in his honor in 2020 as an independent organization dedicated to not only conducting essential climate research, but to harnessing it to inform public  and private sector decision making at all levels of society. dr. woodwell led the center for more than twenty years, was a mentor and friend to many of the center’s staff, and remained a trusted advisor to center leadership to the end. “our entire staff and community is deeply saddened by george’s passing, and our thoughts are with george’s many friends and his family today,” said max holmes, president of the woodwell climate research center. “what drew people to george was not just his intellect or foresight, but also his energy, wisdom, and sense of humor. his ability to sustain outrage and indignation at environmental destruction, while holding an abiding love of the natural world and a clear, positive vision of a better world for all was an inspiration for many.” that vision was the subject of dr. woodwell’s final book, a world to live in: an ecologist’s vision for a plundered planet, published in 2016. over the course of his career, dr. woodwell has published more than 300 scientific papers and authored five books. he was a member of the national academy of sciences and a fellow of the american academy of arts and sciences. he received the 1996 heinz environmental prize, the john h. chafee excellence in environmental affairs award of 2000, and the volvo environment prize of 2001. born on october 23, 1928 to virginia sellers woodwell and phillip mcintire woodwell, dr. woodwell received his bachelor’s degree from dartmouth college, his master’s degree and doctorate in botany from duke university, and served as a commissioned officer in the u.s. navy from 1950 to 1953. he was an avid sailor, and loved his family’s farm and sawmill in maine. he is survived by his wife, katharine rondthaler woodwell, his children and their spouses caroline woodwell (chris deforest), marjorie woodwell (dana woodbury swan), jane woodwell (chris soper), john woodwell (marie hull), and his grandchildren katharine soper, david soper, john deforest, and robert deforest. the family welcomes gifts in woodwell’s memory made to the george m. woodwell endowed fund at woodwell climate research center. a remembrance service will be held at the center in falmouth, ma in coming weeks; more details to follow at woodwellclimate.org/george woodwell. © 2025 woodwell climate research

everyone knows a little about the rise and fall of ddt how it was once hailed as a great boon to mankind; how useful it was in field and garden, house and yard; and how at last to our dismay it was unmasked as a killer, the chemical al capone, a threat to our environment and possibly our very existence. everyone knows that the federal and state governments are acting to end the ddt menace, saving us, if narrowly, from disaster. we can breathe easy again. . . . or can we? the history of ddt is well worth pondering, for its fatal implications extend to the whole of our civilization. the central character of the story is, of course, the chemical compound itself. but there are also two human protagonists a chemist in switzerland and a marine biologist in the united states and our story begins in 1936, a year of crucial career decision for each of them. the chemist, dr. paul herman mûller, was thirty seven years old that year, an employee of the great dye manufacturing firm of j. r. geigy, s.a., of basel. as a remarkably skillful and creative laboratory technologist, he had developed a number of synthetic tanning substances; by 1936 he had turned his attention to pesticide research. also in 1936 a short, slender, solemn faced woman, twenty nine years old and single, was teaching in the zoology department of the university of maryland. in her student years she had majored in english composition as well as biology, followed by postgraduate work at the marine biological laboratory in woods hole, massachusetts. now her desire to write moved her to accept a position in the u.s. bureau of fisheries (soon to be the fish and wildlife service) offered her that year. when the school year ended, her name was listed on the u.s. civil service rolls: "(miss) rachel carson, aquatic biologist. …” meanwhile, dr. müller’s pesticide research was leading to quick results. within a few years he had invented two new insecticides, trade named gesarol and neocid; their specific toxic ingredient, however, remained mysterious to him. in 1939, in search of this specific, he synthesized a chlorinated hydrocarbon whose unabbreviated chemical name is dichlorodiphenyltrichloroethane. müller soon dubbed it ddt. he also soon learned that he was not the first man to make it. back in 1874 a german student named othmar zeidler, working toward a doctor’s degree, had synthesized it as an exercise in pure chemistry. but zeidler had no notion how, if at all, the new compound could be used. not until müller took some of it home with him one day and tried it out on houseflies did anyone realize that ddt kills insects. it was, indeed, the toxic ingredient of the two earlier insecticides müller had compounded. and he soon found ways to make it even more potent. by that time world war ii had begun, and during its opening months müller, having already proved ddt’s effectiveness in controlling colorado potato beetles on crops, found it equally effective in destroying lice on war refugees. with each test, his and his firm’s excitement grew. they became convinced that he had discovered the most powerful synthetic insecticide then known fatal on contact in extremely minute quantities to an incredibly wide range of insects, yet apparently wholly nontoxic to man. geigy quickly patented the formula (1940) as a general insecticide, and the manufacture of ddt began. the patent descriptions were sent to geigy’s branches in britain and the united states and, through them, made known in early 194210 british and american entomologists, who read the patents with mingled hope and skepticism. of immediate concern to them, because of the millions of allied army and navy personnel spread around the world, was ddt’s possible use for control of malaria (carried by anopheles mosquitoes), epidemic typhus (carried by body lice), and dysentery and typhoid fever (both carried by houseflies). with growing desperation they had been searching for a substitute for pyrethrum, a contact insecticide extracted from a flower and, before the war, imported chiefly from japan. war with japan cut off the major source of supply just as the demand for pyrethrum soared. allied doctors and sanitation engineers began to have nightmares about losing the war to germs that could kill more people than all the bombs and bullets imagined in prcatomic years. urgently needed was the kind of synthetic contact insecticide easy and safe to handle, capable of being economically mass produced which ddt seemed to be. british and american scientists were quick, therefore, to begin testing. geigy’s claims, which had at first seemed wildly excessive, were soon verified. with the war production board encouraging its manufacture, ddt production was approaching its wartime maximum of three million pounds a month by the time it was placed on army supply lists in may, 1943, and on navy lists in january, 1944. all ddt was allocated to the armed services save a few hundred thousand pounds for further experiments. among these were field tests in which ddt in powder form was successfully used, in 1943, to arrest small typhus epidemics in mexico, algeria, and egypt. the egyptian work was done under the supervision of the american brigadier general léon fox, a field director of the typhus commission headquartered in cairo. it was fox who was summoned to newly captured, refugee swollen naples in late 1943, where allied medical authorities saw that a major typhus epidemic was in the making. new typhus cases in the city approached sixty a day, and people were dying by the score everywhere, even in the gutters. if the epidemic followed the age old pattern, there would be an explosion of death, with perhaps as many as 250,000 fatalities. in mid december, the general and his men began a systematic dusting of the entire neopolitan population with ddt. within a month the number of new cases per day was in sharp decline. by mid february there were no new cases at all. for the first time in history, in winter (typhus is a winter disease), under filthy, overcrowded conditions perfectly suited to it, a well advanced typhus epidemic was not only arrested but, in a few weeks, totally eliminated. and this was but the beginning of ddt’s march to glory. soldiers and sailors by the million carried small cans of ddt powder to protect themselves against bedbugs, lice, and mosquitoes. they came to love the stuff, especially in the tropics. millions of ddt aerosol bombs were used to spray the interiors of tents, barracks, and mess halls. through european refugee camps, along the burma road, across jungle battlefields of southeast asia, on saipan and dozens of south sea isles infested by stinging, biting insects, ddt spread its beneficent mist. by the war’s end, ddt had become the most publicized synthetic chemical in the world. one american newspaper clipping service accumulated nearly 21,000 items about it in an eighteen month period in 1944 45. most were glowingly enthusiastic; only a few questioned the unmixed blessings of ddt. it was the questions, however, that impressed rachel carson. her career had prospered since 1936. in 1941 she had published a book, under the sea wind , a blend of science and belleslettres which had won critical acclaim, respectable sales, and its author’s appointment as editor in chief of the fish and wildlife service, a post in which she could happily combine her scientific and literary interests. her required professional reading in that post naturally included a good deal about the “miracle” insecticide. what she read disturbed her. for instance, an experiment conducted by the u.s. department of agriculture’s bureau of entomology on may 23, 1945, was reported not only in scientific journals but also in general circulation magazines. at the rate of five pounds per acre an oil solution of ddt was sprayed over a gypsy moth infcsted i,2oo acre oak forest near moscow, pennsylvania. it was terrifyingly effective. every gypsymoth caterpillar in the forest died within hours. but so did every bird at least 4,000 of them within eight days. nor was this the limit of ddt’s mischief. annihilation of ladybug beetles by the spraying resulted in a tremendous multiplication of aphids, which are not affected by ddt but are naturally controlled by ladybugs. the forest was on the way to being completely defoliated when rains halted the outbreak; aphids are shortlived in wet weather. in few if any other tests was the rate of ddi application as high as in the pennsylvania oak forest. one pound per acre was found sufficient to kill gypsymoth caterpillars in a nearby forty acre wood a rate of application that seemed not to harm birds but was still disastrous for aquatic life, a point of special interest to miss carson. and when ddt in this lesser amount was sprayed over peach orchards to kill caterpillars of the oriental fruit moth, it was found to be considerably more destructive of a parasite that attacked the moth than it was of the caterpillars themselves. in other instances, fruit trees were turned literally blood red with spiders, myriad upon myriad of them, after ddt killed the insects that normally fed on them. research reports noted the amazing persistence of ddt’s effectiveness, due to its chemical stability and insolubility in water. pyrethrum as then used in ordinary household sprays was highly poisonous to insects for the first few hours after application but gradually lost all power within a day or two. but ddt, sprayed upon an interior wall, was fatal to flies and mosquitoes for as long as three months; a treated mattress was a fatal resting place for bedbugs for as long as nine months; a ddt sprayed blanket could be laundered a half dozen times, even dry cleaned two or three times, and still kill every moth that touched it. this was an obvious advantage to the army and navy as well as to future civilian consumers, but among biological scientists it raised further questions as to the wisdom of releasing ddt for mass sprayings of fields and orchards, forests and pastures, city parks and tree lined streets, year after year. how could it be removed from sprayed fruits and vegetables since, unlike earlier poisons, it would not wash off? would it persist and build up in soils to a level poisonous to warm blooded animals? and just how toxic was it to such creatures, including man? harmless to man when absorbed in small doses over the short run, might it not build up in fatty tissues (experiments with dogs in 1944 and ’45 proved it did concentrate in fatty tissues) with harmful long term effects? would it be carried by soil erosion into streams and lakes and seas, with deadly effects on aquatic life? and, in general, what effect would its widespread use have upon the ecological balance? these questions, discordant notes in the swelling anthem of praise for ddt, were all explicitly and repeatedly raised in the popular press as well as in special journals by concerned and knowledgeable men in 1944 and during the first nine months of 1945. in early april, 1945, a report was released by the u.s. department of agriculture on two years of nationwide testing of ddt by department entomologists. the report spoke of ddt as a “two edged sword,” at once the “most promising insecticide ever developed” and the most menacing. obviously a great deal more needed to be known about it before it could be deemed “safe for general use,” said time magazine on april 16. nevertheless, ddt was released for general use barely four months later. on august 31, 1945 three days before the end of world war ii the war production board revoked its allocation order reserving the insecticide for military use. certification by government agencies for almost unrestricted agricultural, household, and other uses swiftly followed. the food and drug administration, for example, established as “safe” a ddt content of up to 7 p.p.m. (parts per million) in foods, though no one could possibly know at that time what, if any, level was “safe” over the long run. once ddt was released from wartime federal controls, the government’s power over its production, distribution, and use was diminished, probably more than a trusting public was aware. the u.s.d.a.'s limited control over pesticide manufacture and marketing derived from a igioact of congress primarily intended to protect the farmer against fraud; it lacked any requirement for registering a pesticide before marketing it. the latter was not required until 1947, when congress, facing a flood of chemical poisons in the wake of ddt, passed an insecticide, fungicide, and rodenticide act that incorporated and strengthened major provisions of the 1910 law. consumer protection was broadened to include regulations for proper labelling and detailed instructions for safe use. the quintessential problem of the broad environmental effects of pesticide use was not even considered in the legislation, or in the debate preceding its passage. in 1945 the pressures for ddt’s prompt release were, of course, immense. there were great immediate profits to be made from ddt’s manufacture, distribution, and agricultural use; and there was an eager market for house, yard, and other domestic uses as well. worldwide, there was a desperate need for all the food and fiber that could be produced, and ddt could do more to increase production than any other insecticide. there was an even more desperate need to bring malaria and other insect carried diseases under control, in our own south and in many countries (crcece for one, india for another), and again ddt was the only available product up to the job. for a number of years, the decision to release ddt seemed overwhelmingly justified by its benefits. the worldwide incidence of malaria was spectacularly reduced. in greece, where a third of the work force had been losing two to three months of work time annually to malaria, and where malarial infant mortality in many villages approached 100 per cent, the disease was virtually eliminated from some 6,000 villages by a massive ddt spraying campaign under the auspices of unrra, the united nations relief and rehabilitation agency. at the same time, through the use of ddt against insect pests, farm production was reportedly increased by as much as 40 per cent. in egypt and india, equally remarkable results were achieved. it was reliably estimated that by 1950 ddt had saved five million lives over the world through destruction of malarial mosquitoes. millions more were saved from starvation because of increased food production made possible by ddt. the u.s.d.a. has estimated that, without chemical pesticides, some 30 per cent of america’s protein supply and 80 per cent of her high vitamin crops would be lost to insects∗ and ddt was by far the most widely and heavily used chemical pesticide through the 1950’s ∗this estimate, one must note, is based on the assumption that present methods of single crop farming over huge acreages would continue (strip farming dividing large fields among several different crops would greatly reduce insect hazards) and that increasingly effective biological controls would not be developed. small wonder that the discoverer of ddt was honored throughout the world during the postwar years. though he held no medical degree and had never engaged in medical research, dr. paul herman müller was awarded a nobel prize in medicine for ddt in 1948. and then at the very height of his glory müller dropped from public view. three years later, rachel carson became famous. in 1951 her lyric yet scientifically accurate book about the sea, the sea around us , was published to a chorus of praise; it sold so well that, abruptly, its author became financially independent. she resigned her government job the next year to devote herself to research and writing. her third book, the edge of the sea , appeared in 1955, adding even more luster to her reputation and marking a transition point in her career. the concern she had first felt during the war, as she read about the wartime uses of ddt and about the field and forest tests of the “miracle” insecticide, had become a deeply felt anxiety by the time the edge of the sea was published. she had been quick to grasp the significance of an announcement in early 1946 that u.s.d.a. entomologists had succeeded in producing, through selective breeding in a laboratory, a strain of housefly much more resistant to di)i than the common stock. “in view of the increasing use of ddt for housefly and mosquito control,” said science , cautiously, on march 12, 1946, “it seems possible that, in time, a similar increase in resistance may occur under natural conditions.” it had happened before, with other insecticides. and, sure enough, ddt resistant strains of houseflies, mosquitoes, and crop destroying insects soon began to appear naturally and in such numbers in some areas that ever more massive doses of insecticide were required to control them. miss carson recognized the implications of this genetic evolution. what if ddt’s effectiveness were so reduced, in the not distant future, as to require extensive use of the even more toxic chlorinated hydrocarbons (dicldrin, aldrin, chlordane, endrin) which ddt’s success had inspired? would not these in turn lose effectiveness? no doubt chemicals still more toxic would by then be available; but what consequences would follow from their use if, indeed, they were not so lethal to men as to be unusable? rachel carson, like other biologists, saw nightmare answers to these questions. the end of the process might be an environment far more hostile to man than to his insect “enemies.” after all, insect generations succeed themselves hundreds of times more rapidly than human generations. if man insisted on running a genetic adaptability race with insects, he was bound to lose. the evidence that ddt was poisoning the environment multiplied throughout the iggo’s. there were increasingly frequent reports of direct poisonings of birds, of fish, of small game, sometimes after applications in excess of prescribed amounts but often, too, when the prescriptions were precisely followed. one day in january, 1958, olga huckins wrote a long, eloquently angry letter to her friend rachel carson, describing the deadly effect of ddt spraying for mosquito control over the huckinses’ private two acre bird sanctuary at powder point, in duxbury, massachusetts. not long afterward miss carson was a house guest at powder point when, late in the afternoon, the spraying plane came over. the next morning she went through the estuary with the huckinses in their boat. she was sickened by what she saw dead and dying fish everywhere, crayfish and crabs dead or staggering as their nervous systems were destroyed. “you ought to write about this,” the huckinses kept saying. “you’ve got to.…” and rachel carson, publicity shy, no controversialist by temperament, acutely aware of the abuse in store for anyone who dared challenge the million dollar pesticide industry, was forced to agree  especially as she came to realize that the direct kills were by no means the worst effect of the chemical pesticides. more widespread and disastrous by far were the delayed kills, coupled with the inhibition of reproductive processes. entire species of birds were threatened with extinction. and how could a substance so toxic to other warm blooded animals fail to have toxic effects, in the long run, on humans? for as the stubbornly persistent ddt enters a food chain that begins with herbivores and runs through small to large and then larger carnivores, including man, the process known as “biological magnification” occurs. an early instance was recorded on the east lansing campus of michigan state university. annual spraying of elms with ddt began there in 1954 to control the beetle that spreads dutch elm disease. for the first year or so there were no apparent side effects. but then people noticed that there were no more robins on the campus. earthworms feeding on elm leaves with tiny amounts of ddt on them accumulated the stuff in their body fat until a level toxic to robins was reached. robins that ate those worms died and robins unfortunate enough to visit the campus even two years after spraying had been discontinued also died. in other studies the magnification rate in specific food chains was measured. in the bottom of lake michigan’s green bay, for example, live billions of tiny crustaceans. the mud was found to contain 0.014 p.p.m. of ddt; the crustaceans, absorbing ddt from the mud, concentrated it in their bodies to 0.41 p.p.m.; fish, feeding on the crustaceans, concentrated ddt in their bodies to from 3 to 6 p.p.m.; herring gulls feeding on the fish accumulated ddt to the level of 99 p.p.m. this concentration, though not immediately fatal to individual gulls, reduces normal reproduction. the eggs of these herring gulls contained 227 p.p.m. of ddt, and their shells were abnormally thin. by the late 1950’s it was clear to miss carson, and other knowledgeable observers, that ddt’s increasingly massive invasion of the food chain was largely responsible for the fact that bald eagles were ceasing to breed on the east coast between florida and maine (large concentrations of ddt residues were found in the brains of prematurely dead eagles) ; that eagles in the great lakes region faced extinction because their egg shells were growing too thin (the physiological mechanism by which ddt inhibits calcium production would soon be discovered); that peregrine falcons were disappearing as breeding birds in the whole eastern half of the u.s.; that ospreys would disappear from connecticut by the early 1970's if present rates of decline continued. nor was ddt’s invasion of the food chain limited to land or to offshore waters. oceanic food chains were being similarly contaminated, and ocean currents were spreading ddt residues to the most remote corners of the earth. predictable in a general way by the pattern of events was the sad case of the bermuda petrel, a carnivorous bird that feeds solely on oceanic life far from any area where ddt is used. the bird comes to bermuda for only a few hours, at night, to lay its eggs. it eats nothing there. yet its eggs in the late 1960’s contained 6.44 p.p.m. of ddt on the average, and its reproduction was declining at a rate which, if continued, must end in complete reproductive failure by 1978. even antarctica’s adélie penguins, weddell seals, and skua gulls, carnivores all, were soon found to carry trace amounts of ddt in their fat, though they live thousands of miles from the nearest area of ddt use. undoubtedly they ingest ddt residues in their food. but ddt was also found, in the 1960’s, in antarctic snow,∗ indicating that the food chain is not the only means by which the poison spreads. studies conducted in maine and new brunswick, canada, in the 1950's showed that approximately half the ddt sprayed over forests at treetop level hung suspended in the atmosphere to be spread worldwide on the wind. ddt attached to erosion debris also travels in irrigation water, rivers, and ocean currents. ∗some 2,400 tons of it have been estimated to have accumulated by now in antarctica’s snows. the realization that the oceans’ organisms are becoming depositories for ddt has led some ecologists to premonitions of an apocalypse, based on the assumption that much of the oxygen in the atmosphere is produced through photosynthesis by marine phytoplankton (vegetable life). hence, anything that might inhibit oceanic photosynthesis on a large scale is a threat to life on earth. scientists of this persuasion took little comfort in the 1968 report by charles f. wurster, jr., of the state university of new york at stony brook; in the laboratory very low concentrations of ddt had measurably reduced photosynthesis in cultures of four species of coastal and oceanic phytoplankton representing four major classes of algae. furthermore, the same had been found true of a natural phytoplankton community (as distinct from a laboratory culture) at woods hole. “i’ll tell you what we worry about most,” said david m. gates, director of the missouri botanical garden in st. louis, to a reporter in 1969, " an irreversible catastrophe. a number of pesticide spills, for example, in those areas of the ocean where … much of the world’s oxygen [is produced]. if you plot the frequency of this kind of event, they’re getting closer and closer.” much of this kind of fear has been allayed by recent scientific findings that suggest that no significant interchange of oxygen occurs between ocean and atmosphere, and, in addition, that some phytoplankton are considerably less sensitive to pesticides than others. such findings, of course, do not alter the fact that any large scale interference with ocean life would have serious repercussions. whatever its ultimate effects may be, the frightening fact is that most of the hundreds of millions of pounds of ddt sprayed over the world during the last quarter century remain in circulation  only a fraction has decayed into harmless substances and no one can say what fatal damage it alone (apart from the ddt being constantly added) may yet do. credit for the fact that public, governmental, and scientific attention was focused on the threat of ddt and other chemicals in the environment must certainly go to rachel carson’s silent spring . researching it meticulously (her argument was sustained by no fewer than fifty pages of closely printed source notes), she wrote the book in longhand, slowly, most of it in her home in silver spring, maryland, and much of it at night, over a period of nearly four years, beginning in 1958. she well knew that her warning of the threat to the environment from the indiscriminate use of ever more and stronger pesticides would provoke attacks upon her motives, professional competence, and “scientific objectivity"; and so she was not surprised by the storm of controversy her book aroused even before its formal publication date in 1962. but with scientific colleagues, with the general public, and with many governmental policy makers, silent spring was enormously persuasive. one of rachel carson’s central points was that man, like every living thing, is a creature of his environment, and, consequently, any chemical fatal to his environment must ultimately be fatal to him (a concept commonly understood today but new to many a decade ago). she also challenged the constantly reiterated assertion that ddt and its close chemical affiliates are not directly toxic to human beings. true, most americans now probably have 10 to 12 p.p.m. ddt in their body fats, which is 3 to 5 p.p.m. more than the f.d.a. set tolerance level for human food; and we seem unharmed by it. but what of the effects that may not show up for two or three decades or generations? is ddt damaging chromosome structure? is it, through subtle attacks on the central nervous system, slowly impairing mental processes? is it a carcinogen (cancer inducing agent)? rachel carson cited disturbing evidence that the answer to such questions might be affirmative. today ddt is increasingly suspected of direct injury to man. evidence of the carcinogenic effects of ddt have multiplied since 1962. indeed, in the very year following publication of silent spring , dr. william c. h. hueper of the national cancer institute reported ddt to be “cancer producing according to presently available evidence” and incriminated ddt in the “production of benign and malignant tumors of the liver, cancers of the lung, and leukemias.” two years after her best seller was published in mid april, 1964 rachel carson, aged fifty six, died of cancer. (dr. paul müller died in october of the following year, at the age of sixty six.) but before she died she had the satisfaction of knowing that her work was influencing public policy. in 1963, in direct response to the public concern aroused by silent spring , president kennedy’s science advisory committee recommended a reduction of ddt use with a view to its total elimination as quickly as possible, along with other “hard” pesticides. soon thereafter secretary of the interior stewart udall issued an order banning the use of ddt on interior controlled lands “when other chemicals can do the job.” wisconsin, michigan, california, massachusetts, and other states began to move toward state prohibitions of ddt. finally, in november of 1969, acting on the recommendation of a special study commission on pesticides, robert h. finch, secretary of health, education, and welfare, announced that the federal government would “phase out” all but “essential uses” of ddt within two years. many americans assumed that this phasing out means the end of ddt. but not so. even though, belatedly, the search has been intensified for safe alternatives to persistent pesticides, the worldwide demand for ddt increases as underdeveloped countries face the immediate desperate problems of feeding and protecting the health of exploding populations. the u.n.'s world health organization and the food and agricultural organization have strongly opposed any prohibition or even reduction of ddt’s use, arguing that it is the cheapest effective pesticide (it costs about fifteen cents a pound as compared with a dollar or more for other chemicals), that poor countries cannot afford substitutes, and that without the kind of crop protection and disease control provided by ddt, millions must surely and quickly die. in india, for instance, u.n. consultants are now working with the government to double within a year the percentage of cropland sprayed by hard pesticides, chiefly ddt. even in america the government has moved so slowly to implement its “phase out” policy that citizen conservation groups, led by the crusading environmental defense fund, have taken action to stop the manufacture and use of ddt through legal suits against government agencies and the major manufacturer. and so the use of ddt continues, even as its disastrous effects on living things are being established beyond any doubt. the need for some system of broadly assessing the likely consequences of technological innovations before they are unleashed seems all too apparent. in the case of ddt, however, we can only hope to live with our mistakes. now in its 75th year, american heritage relies on contributions from readers like you to survive. you can support this magazine of trusted historical writing and the volunteers that sustain it by donating today. donate the literary lights were always bright at “life style” in the nineteenth century mrs. piper and the professors in this final installment from our series on general joseph w. stilwell, barbara w. tuchman recounts the story of the old soldier’s finest hour “almost every time a serious disarmament effort got under way, it barely managed to move forward an inch or two before a great world cataclysm intervened” or don’t put off until tomorrow what you can ram through today an american heritage original document edited and with an introduction disarmament hypocrisy was skewered by “mr. dooley, ” finley p. d’fcnne ‘s philosophical, fictional barkeeper, in this “report” of the 1907 hague conference at which the chief u.s. delegate was a well known legal wit, joseph h. choate. the rough rider rode roughshod over writers who took liberties with mother nature’s children “then how come they’re digging a grave behind the old corral, luke?” for 75 years, american heritage has been the leading magazine of u.s. history, politics, and culture. read more about the magazine >> the magazine was forced to suspend print publication in 2013, but a group of volunteers saved the archives and relaunched it in digital form in 2017. free subscription >> please consider a donation to the 501(c)3 national historical society to help us keep this american treasure alive. support with a donation>> © copyright 1949 2024 american heritage publishing co. all rights reserved. to license content, please contact licenses [at] americanheritage.com.

supported by the founder of the renowned woods hole research center in massachusetts, he also helped shape u.s. policies on controlling toxic substances like ddt. by keith schneider george m. woodwell, the founder of the woods hole research center in massachusetts and a renowned ecologist whose keen research and understanding of policy shaped how the united states controlled toxic substances and how the world confronted climate change, died on tuesday at his home in woods hole, mass. he was 95. the research center, which dr. woodwell started in 1985 to study global climate change, and which was later renamed for him, announced his death in a statement. during his long career, dr. woodwell repeatedly shined a light on how the byproducts of new technologies   devised to increase efficiency in the agriculture, forestry and energy industries   had endangered natural systems. his research provided early evidence of what he called “biotic impoverishment”   the steady weakening of plants, animals and ecosystems that are chronically exposed to synthetic pollutants. dr. woodwell published more than 300 scientific papers, many of them in science, scientific american and other leading journals. he held teaching and research positions at the university of maine, brookhaven national laboratory, yale university and the marine biological laboratory. but he was an activist at heart who was not afraid to leverage credible scientific findings to influence public attitudes and policy. he was at the center of the national campaign to end atmospheric testing of nuclear weapons in the 1960s and the effort to ban ddt and other dangerous farm chemicals in the 1970s. dr. woodwell was also among the first scientists to recognize the threats to nature and human life associated with rising levels of carbon dioxide in the earth’s atmosphere. in 1972, he convened a conference, carbon and the biosphere, at brookhaven, on long island, that was attended by 50 internationally recognized climatologists, oceanographers and biologists. it was the first international gathering ever held on what is now called climate change.
