DDT, just another one of Monsanto's little gifts to humanity...sylvie said:The pre WWII survey comparison would be invalidated by the extensive use of DDT which was discovered in the 1800's and used from 1939 through 1972. This is not to say that companies weren't allowed to exhaust the already purchased supplies of DDT; that a corporate phase out could have extended well beyond 1972 for some crops like animal feed. A study would have serious control issues.
