You are so right of troy, DDT can accumalate in the fatty tissue of birds that eat insects that have been sprayed with DDT. But unlike you I have read Silent Spring and was very impressed with the artful prose and became an advocate of protecting our oceans and rivers from insecticides. For thirty years I believed in the evil of DDT. So did and so do others. But I find today that the facts don't support the contention. Thirty years before the the use of DDT became widespread the egg shells of birds were thining as is evidenced by the eggshells that have been examined in museums. Acid rain? Maybe. But we should know the truth before reacting like children and banning chemicals that can perhaps save the children of backward countries from starvation.

All chemicals can be considered toxic when overpresent in the human body. All I ask is for we the blessed to consider the unblessed when choosing our things to hate.

What is wrong with proofs?
