The United States is the only nation that still uses chimpanzees in large-scale, invasive research. Many countries have banned research and testing on chimpanzees because of a growing awareness of the scientific problems with these experiments. But the movement to end research on chimpanzees is also based on our knowledge of their rich social and emotional lives-and the suffering caused by life in a laboratory.

Please urge your U.S. representative to co-sponsor the Great Ape Protection Act, which would phase out invasive research on chimpanzees and release federally owned chimpanzees to sanctuaries.
