Following five years of work by PETA scientists and nearly 25,000 responses to our action alert, the Environmental Protection Agency (EPA) has agreed to incorporate many of PETA’s recommendations into its Endocrine Disruptor Screening Program. The EPA’s new plan, called “EDSP21,” calls for the use of existing data, computer models, and in vitro methods to prioritize and screen chemicals. PETA’s scientists worked exhaustively for the past five years to push the EPA in this direction by publishing op-eds, lobbying, making presentations at conferences and workshops, and submitting legal petitions, technical comments, and testimony. PETA’s recently published article in a major scientific journal provided the EPA with a clear pathway that is strikingly similar to the EDSP21 plan. As a result of these efforts, 3 million animals may be saved from being used in painful experiments!
