Should DDT have been banned?
DDT should be phased out of use and ultimately banned. Because DDT can travel long distances and accumulate in the body, millions of humans and animals worldwide have buildups of the chemical in their tissue, even though it may have been used on another continent.
How many lives did DDT save?
500 million lives
Did Rachel Carson have cancer?

When was DDT first banned in India?
1989
What is DDT Silent Spring?
Silent Spring is an environmental science book by Rachel Carson. It spurred a reversal in the United States’ national pesticide policy, led to a nationwide ban on DDT for agricultural uses, and helped to inspire an environmental movement that led to the creation of the U.S. Environmental Protection Agency.
What did Rachel Carson want banned?
Carson’s most direct legacy in the environmental movement was the campaign to ban the use of DDT in the United States (and related efforts to ban or limit its use throughout the world).

Rachel wrote a book on her findings which she called Silent Spring. Rachel even helped other people see the dangers to wildlife that we still invoke today. Rachel Carson is my hero because she helped nature survive and we both agree that nature is an important part of this world.
Why did Rachel Carson want to stop using DDT?
The ban was intended to prevent the imminent extinction of ospreys, peregrine falcons, and bald eagles, our national bird, among other species; they were vulnerable because DDT caused a fatal thinning of eggshells, which collapsed under the weight of the parent incubating them.
Did DDT save lives?
The only solution is to exterminate the mosquitoes that spread these diseases by pesticides. The most potent of these is DDT. The US National Academy of Sciences estimated DDT had saved 500 million lives from malaria by 1970.
What did Rachel Carson do as a marine biologist?
Rachel Carson was a world-renowned marine biologist, author and environmentalist who served as an aquatic biologist and editor-in-chief for the U.S. Fish & Wildlife Service. She has been credited with launching the contemporary environmental movement and awakening the concern of Americans for the environment.
Why was silent spring so influential at the time?
Silent Spring was met with fierce opposition by chemical companies, but it spurred a reversal in national pesticide policy, led to a nationwide ban on DDT for agricultural uses, and inspired an environmental movement that led to the creation of the U.S. Environmental Protection Agency.
Has DDT killed anyone?
There is evidence that overuse of DDT in the 1950s and 60s caused environmental harm in specific, unusual cases — such as fish kills from massive over-spraying of river insects — but no study has ever confirmed any human health problems linked to DDT.
What countries still use DDT today?

Is DDT really dangerous?
Human health effects from DDT at low environmental doses are unknown. Following exposure to high doses, human symptoms can include vomiting, tremors or shakiness, and seizures. Laboratory animal studies showed effects on the liver and reproduction. DDT is considered a possible human carcinogen.
Does DDT cause birth defects?
Earlier studies have linked DDT to birth defects, a higher risk of Type 2 diabetes, and fertility problems. In this study, the researchers tracked the 9,300 daughters born to women who participated in the Child Health and Development Studies (CHDS) for 54 years.
Who got DDT banned?
In May 1963, Rachel Carson appeared before the Department of Commerce and asked for a “Pesticide Commission” to regulate the untethered use of DDT. Ten years later, Carson’s “Pesticide Commission” became the Environmental Protection Agency, which immediately banned DDT.
Why was Silent Spring banned?
Kennedy ordered the President’s Science Advisory Committee to examine the issues the book raised, its report thoroughly vindicated both Silent Spring and its author. As a result, DDT came under much closer government supervision and was eventually banned.
Is DDT still in use?
Dichlorodiphenyltrichloroethane (DDT) is an insecticide used in agriculture. The United States banned the use of DDT in 1972, but some countries still use the chemical. It is still in use outside the United States for the control of mosquitoes that spread malaria.
Why does India still use DDT?
In many parts of India, DDT is ineffective. Agricultural uses were banned in 1989 and its anti-malarial use has been declining. DDT can still be effective against resistant mosquitoes and the avoidance of DDT-sprayed walls by mosquitoes is an additional benefit of the chemical.
