Hasn't most of the anti-DDT stuff that got it banned been disproved? I see no reason for specifically penalizing the tool which almost singlehandedly got rid of malaria in the South.
Journal of Environmental Health Perspectives (October '07) found that exposure to DDT at a young age can increase one's risk of breast cancer fivefold, and the British Journal of Urology in 2009 found some urogenital birth defects linked to DDT exposure. It also threatens our ability to export crops that may be contaminated with DDT to nations where it's banned (much of Europe).
