Leftist theories kill millions. Another example...

Tens of millions.

This is the same general catastrophe I wrote about last week here. And Here. To these people, the theory is real; the actual human beings affected are not real. So humans can be killed without a qualm.

Malarial mosquitoes, not bedbugs, are the real pest--Paul Driessen - NYPOST.com:

...DDT is the most powerful, effective, long-lasting mosquito repellant ever invented. Spraying the eaves and inside walls of mud huts and cinderblock homes every six months keeps 80 percent of the flying killers from entering. It irritates most that do enter, so they leave without biting, and kills any that land.

Yet many aid agencies refuse to encourage, endorse or fund spraying. Many don't even want to monitor mosquito and malaria outbreaks or determine success in reducing disease and death rates. That's more difficult and costly than counting the number of bed nets distributed and underscores the embarrassing reality that their "comprehensive" (and politically correct) programs achieve only 20 to 40 percent reductions in morbidity and mortality. By contrast, as South Africa and other countries have shown, adding insecticides and DDT can bring 95 percent success.

Since the Environmental Protection Agency banned DDT in 1972, billions have been stricken by malaria and tens of millions have died. This is intolerable.

We need adult supervision and informed debate on pesticide policies, laws and regulations. We can no longer leave those decisions to anti-chemical activists in unaccountable pressure groups and government agencies. These zealots are making decisions that affect the quality of life for millions of Americans -- and life itself for billions of poor people worldwide....

"Many don't even want to monitor mosquito and malaria outbreaks or determine success in reducing disease and death rates." They don't want to know!
