Excerpt:

Who is the worst killer in the long, ugly history of war and extermination? Hitler? Stalin? Pol Pot? Not even close. A single book called Silent Spring killed far more people than all those fiends put together.

Published in 1962, Silent Spring used manipulated data and wildly exaggerated claims (sound familiar?) to push for a worldwide ban on the pesticide known as DDT – which is, to this day, the most effective weapon against malarial mosquitoes. The Environmental Protection Agency held extensive hearings after the uproar produced by this book… and these hearings concluded that DDT should not be banned. A few months after the hearings ended, EPA administrator William Ruckleshaus over-ruled his own agency and banned DDT anyway, in what he later admitted was a “political” decision. Threats to withhold American foreign aid swiftly spread the ban across the world.

The resulting explosion of mosquito-borne malaria in Africa has claimed over sixty million lives.

What causes environmentalists to want to murder millions of innocent people?

As quoted by Walter Williams, the founder of the Malthusian Club of Rome, Alexander King, wrote in 1990: “My own doubts came when DDT was introduced. In Guayana, within two years, it had almost eliminated malaria. So my chief quarrel with DDT, in hindsight, is that it has greatly added to the population problem.” Another charming quote comes from Dr. Charles Wurster, a leading opponent of DDT, who said of malaria deaths: “People are the cause of all the problems. We have too many of them. We need to get rid of some of them, and this is as good a way as any.”

Abortion killed 50 million people in the United States alone, while atheistic communism killed 100 million people in the 20th century. And remember: Obama’s science czar is a radical environmentalist who advocates coerced abortions.
