Animal rights activists are rejoicing this week. On Tuesday, the Environmental Protection Agency (EPA) announced a move to “aggressively reduce animal testing” and to stop funding mammal tests by 2035. EPA Administrator Andrew Wheeler promised to reduce new mammal tests by 30 percent by 2025 and pledged $4.25 million toward developing non-animal alternatives for testing chemical safety. “Part of why I’m doing this today is because it’s been 30 years and we haven’t made enough progress,” said Wheeler, who wrote an anti-animal testing op-ed for his college paper in 1987.
