Can you elaborate? I had only heard that bal eagles were affected by DDT. What's the real story?
Search around junkscience.com All of the scientific panels were against banning DDT, and there was never any evidence that DDT was causing any birds to have "thin egg shells" or any of that nonsense. The government banned DDT over the advice of scientists over political pressure. Since then, literally million around the world have died of Malaria, which had become practically non-existent by the early 70's. Malaria came roaring back when DDT was banned.
Yes, the eagles and such have made a come-back since DDT was banned. But that is also when it became illegal to shoot them.
Yes the eagle population was affected by DDT. Their numbers exploded as did other predatory birds because of the reduction in disease carrying insect vectors.
Sadly since the ban tens of millions of people have had to suffer illness and death from Malaria that otherwise would not have had to.
