Chapters
00:00 - 01:00: Rachel Carson's Silent Spring and its Impact Rachel Carson's 'Silent Spring' has been sold over 500,000 times, becoming one of the nation's bestsellers and the most controversial book of the year. The book criticizes the use of powerful pesticides such as DDT, sparking the American environmental movement. Rachel Carson is highlighted as an influential figure who significantly altered people's lives. However, the reduction in the use of pesticides like DDT also posed challenges, particularly in the battle against malaria.
01:00 - 02:30: The Case Against DDT This chapter critically analyzes the impact of DDT ban largely influenced by Rachel Carson's environmental advocacy. It argues that the elimination of DDT has led to a resurgence of malaria in third world countries, resulting in the deaths of millions of children. The narrative presents a view that environmental regulation, propelled by Carson's work, may have gone too far, thus challenging the core principles that led to the formation of the Environmental Protection Agency (EPA). The chapter's discourse portrays Carson as a controversial figure, suggesting her influence may have had unintended negative consequences for public health.
02:30 - 04:00: Carson's Legacy and the Ongoing Fight Against Malaria The chapter titled 'Carson's Legacy and the Ongoing Fight Against Malaria' discusses the lasting impact of environmentalist Rachel Carson's work, particularly in relation to the fight against malaria. It highlights the simplicity with which complex issues are often addressed and suggests learning from Carson's nuanced approach. The narrative reflects on Carson's love for nature, her soft-spoken demeanor, and her passion for exploring tide pools on rocky Atlantic shores, drawing a parallel between her environmental advocacy and the ongoing global struggle against malaria.
04:00 - 06:00: The Problem with Over-Reliance on DDT and Other Insecticides The chapter discusses the over-reliance on DDT and other insecticides, emphasizing the interconnectedness of creatures in their habitats and their relationships with each other. Rachel Carson, a naturalist and science writer, spent many years encouraging Americans to appreciate the beauty of nature. In her 1962 publication of 'Silent Spring,' Carson's message shifted as she highlighted that humanity is part of nature, and waging war against it is akin to waging war on oneself.
06:00 - 08:00: The Continuing Evolution of Mosquitoes The chapter discusses the historical and scientific significance of DDT, a powerful insecticide used to combat malaria-carrying mosquitoes, particularly during World War II. DDT was so effective that its discovery earned a Nobel Prize, marking a significant technological advancement for mankind against insects. However, the chapter also reflects on the ethical and ecological implications of using such potent pesticides, considering their massive impact on insect populations.
08:00 - 10:00: Innovative Approaches in Malaria Control The chapter "Innovative Approaches in Malaria Control" discusses the widespread application of DDT, which was once celebrated as a revolutionary solution to pest control. At its peak, more than 80 million pounds of DDT were used annually in the United States, covering a wide range of areas including forests, cropland, and suburban homes. This period marked the beginning of what was known as "better living through chemistry," with DDT regarded as a miracle solution that would kill any insect on contact.
10:00 - 12:30: Conclusion: The Need for a Holistic Approach to Pest Control The conclusion chapter highlights the disastrous effects of indiscriminate insecticide use, particularly DDT. While extremely effective in reducing insect populations, this chemical approach created significant hidden damages. The research by Carson highlighted the invisible yet profound threats posed by such chemicals, emphasizing the need to consider unintended consequences in pest control measures. This chapter advocates for a more holistic approach, moving away from purely chemical solutions to protect the ecosystem.
Rachel Carson’s Warning on D.D.T. Ignited an Environmental Movement | Retro Report Transcription
00:00 - 00:30 This is one of the nation’s bestsellers.
Up to now, 500,000 copies have been sold, and Silent Spring has been called the most
controversial book of the year. Rachel Carson’s push to limit the use of powerful pesticides like DDT helped spark
the American environmental movement. Rachel Carson is one of those rare individuals who brought about change in all of our lives. But the seeming loss of this pesticide
in the fight against malaria also turned her
00:30 - 01:00 into a poster child for environmental regulation
gone too far. DDT was eliminated and malaria made a comeback and millions of children in third world have
died because of this nonsense. Although environmentalists worship her, I say she’s a mass murderer. If you discredit Rachel Carson, you discredit
the founding principle of the EPA. The idea that Carson gave DDT such a bad name that
it became banned in much of the world is a
01:00 - 01:30 gross oversimplification. As the world continues its fight against malaria,
what lesson does Silent Spring hold? She was a very soft-spoken soul who loved nothing better than going down to the tide
pools of the rocky Atlantic shores and studying
01:30 - 02:00 creatures in their habitats and their relationship
to each other. The naturalist and science writer Rachel Carson spent decades urging Americans to see the
beauty around them. But in 1962, Carson published Silent Spring, and her message took on markedly
different tone. Man is part of nature, and his war against nature is inevitably a war against himself.
02:00 - 02:30 To Carson, that war was exemplified by the
growing use of DDT — a potent synthetic insecticide that was so revered for its ability
to kill malaria-carrying mosquitoes during World War II that its discovery led to a Nobel Prize. This diabolic weapon of modern science saved millions of humans but killed billions of
insects. Men with this newly discovered force has at long last gained the upper hand in
our age old struggle.
02:30 - 03:00 DDT was soon billed as the solution to
every insect pest. And, in time, upwards of 80 million
pounds was being sprayed annually in the U.S. alone — applied to everything from vast
forests and cropland to spreading tracts of suburban American homes. This was the advent of “better living through
chemistry,” and DDT was the wonder child. Once a bug comes into contact with DDT, he is lost.
03:00 - 03:30 The effect is disastrous. Basically like a chemical holocaust against
these insects, it drove lots of insect populations down. And it was enormously effective. But Carson’s research showed the massive
spraying of DDT and other insecticides was causing a hidden harm. Carson forced us to consider an invisible
threat, something that we might not smell, you might not see; but which had all kinds
of unintended consequences.
03:30 - 04:00 We poison the caddis flies in a stream, and the salmon runs dwindle and die. We poison
the gnats in a lake, and the poison travels from link to link of the food chain. We spray our elms, and the following springs are silent of robin song. She alerted us to the possibility that, in
trying to improve on nature, we were actually poisoning ourselves. But to have a woman question
the authority of science, and then of scientific
04:00 - 04:30 men was something that created a great deal
of discomfort in some quarters and downright hostility in others. Time magazine called Miss Carson’s book
an “emotional and inaccurate outburst.” The major claims in Ms. Rachel Carson’s book, Silent Spring, are gross distortions
of the actual facts. If man were to faithfully follow teachings of Miss Carson, we would
return to the Dark Ages, and the insects and
04:30 - 05:00 diseases and vermin would once again inherit
the earth. But, as evidence mounted that DDT was a persistent and damaging environmental toxin, its pervasive
spraying raised increasing political and scientific alarm. A government-backed scientific panel today
reported that pesticides may, indeed, represent a grave threat to mankind. The average American already has more DDT
in his body than is permitted in the meat and fish that we eat. It does not go away.
It accumulates, and it passes to babies through
05:00 - 05:30 their mother’s milk. By the 1970s, Carson was being hailed as an
environmental hero, while DDT was in retreat— with a host of developed countries, including
the US, severely limiting its use. Silent Spring forced us to reconsider a fundamental faith in science and technology. But, as the decades passed, the disaster some
critics had predicted seemed only too near.
05:30 - 06:00 In Africa and Asia, the mosquito is a mass killer. More than 2 million people die every
year from malaria, which mosquitoes transmit. The Center for Disease Control estimates that a child in Africa dies from malaria every
30 seconds. And the critics knew just whom to blame. By the 1960s DDT had all but eradicated malaria... then came Rachel Carlson’s Silent Spring
book. Her misleading bestseller
got the pesticide DDT banned.
06:00 - 06:30 But the progressive nut balls had it wrong,
as usual. And what is the result of DDT being banned? Malaria out of control in third world countries
where before it had been nearly eliminated. But places like Burkina Faso tell a different
story. Even though DDT was never banned in the fight against insect-born disease here,
the tiny country has become an epicenter of the world’s malaria epidemic.
06:30 - 07:00 During the rainy season, health clinics like
this one in the village of Soumoussou are packed with patients suffering from malaria.
Nearly 40 percent of the country’s residents end up contracting the disease every year. Go to any single healthcare. You will see
for yourself. You will see a lot
07:00 - 07:30 of people with kids there I mean just laying
down on the floor, suffering and then waiting for the treatment. The problem is that the mosquitoes here have
become resistant to the pesticides used against them, including DDT. Insects are very good at out-evolving constraints,
and so all over the world lots of different insect species developed resistance against DDT.
07:30 - 08:00 Mosquitoes that had a genetic propensity to
metabolize DDT survived the spraying, and every year, those survivors reproduced and
multiplied. In many African countries, that resistance combined with decades of government neglect,
poor infrastructure and abysmal health care systems to turn malaria into a perfect storm. In West Africa you can’t really use DDT,
because resistance is extremely high pretty
08:00 - 08:30 much everywhere. DDT didn’t work. Which is nothing to do
with Silent Spring. In fact, Carson had warned of this very problem. Inevitably, it follows that intensive spraying with powerful chemicals only makes worse the
the problem it is designed to solve. Rely on a single insecticide, you’ll get immune insects. Over the last decade, malaria rates have come
down through a combination of new anti-malarial drugs and insecticide treated bed nets. But
these results are endangered by the same mistakes
08:30 - 09:00 – over-reliance on a small set of tools,
including pyrethroid insecticides. It used to be that you could kill a mosquito with pyrethroid insecticide in minutes. Now,
ten hours of exposure kills about 25 percent of them. Unless we get new technologies to
box in the mosquito very quickly, then we’re probably gonna lose all the gains we’ve
got from the last ten years.
09:00 - 09:30 That's because the mosquito continues to adapt -- evolving not only new defenses to insecticides,
but new feeding habits as well. Some mosquito populations can actually recognize the silhouette of a door, and they go for
people when they come in and out of doorways. That’s how sophisticated evolution can be
in changing the behavior. Here, in this cluster of research sites set among Burkina Faso’s rice fields and villages,
promising new strategies are put through their
09:30 - 10:00 paces — including one developed in Raymond
St. Leger’s Maryland lab. Most insects don’t die of old age, or because they get snapped up by a passing bird. They
actually get killed by disease. And more insects die from fungal disease than any other kind
of disease agent. St. Leger decided this fungus could be improved upon, so he genetically altered it to produce
a spider venom, turning the fungi into a mosquito terminator of sorts. So, basically it’s a vehicle which makes
its own insecticide and then functions like
10:00 - 10:30 a hypodermic. The fungus injects the insecticide
straight into the blood of the insect. Since mosquitoes must first be infected by the malaria parasite before they can pass
it onto humans, Johns Hopkins University immunologist George Dimopoulos has genetically supercharged
the the mosquito’s natural defenses against contracting the disease. He has also used bacteria found in mosquitoes
intestines to help block the development of the parasite before it can multiply. It’s like giving the mosquito a probiotic
that protects them against malaria.
10:30 - 11:00 So, you can put all of these different, innovative approaches together. They all dovetail with
each other, and that’s gonna be the solution. The solution isn’t gonna be relying on any
single technology as the silver bullet. These scientists stress the need for a more holistic view of pest control, which is exactly
what Rachel Carson was advocating for in Silent Spring. Despite claims by some modern-day
critics, Carson understood there was still
11:00 - 11:30 a need for pesticides. We must go on to think in terms of other methods
of control, of much more scientific, much more accurate and precise methods. You can’t
just step in with some brute force and change one thing without changing a good many others. We are learning that lesson. We’re doing
our best to learn that lesson. The mosquito, meanwhile, continues to evolve,
11:30 - 12:00 an ever-adaptable animal… carrying not just
malaria, but Dengue, Yellow Fever, Zika, and a host of other diseases… as it pursues
its ancient hunt for human prey. A recent study estimated that vector-borne diseases – mostly mosquito-borne diseases
– have killed half of all the humans who’ve ever lived. They are by far and away the most
dangerous animal. They’re even more dangerous to us than other people are. So, ideally,
we want to develop an evolution-proof system
