  3. A Lie • Page 17 . Carson says arsenic is a carcinogen and mentions a great many horrible ways in which it is violently poisonous to vertebrates. She then says(page 18) :” Modern insecticides are still more deadly” and she makes a special mention of DDT as an example. This implication that DDT is horribly deadly is completely false

  4. Human Volunteers have ingested as much as 35milligrams of it a day for nearly two years and suffered no adverse affect.

  5. Millions of people have lived with DDT intimately during the mosquito spray programs and nobody even got sick as a result • In house spraying, the amount applied was 2 grams of DDT per square meter of wall, every 6 month

  6. DDT’s contribution • The World Health Organization Director concluded,” The discontinuation of the use of DDT would be disaster to world health” • The national Academy of Sciences concluded in 1965 that” in a little more than two decades, DDT has prevent 500 million human deaths that would otherwise have been inevitable ”
