Tell Congress to End Chimpanzee Experiments

Chimpanzees—humans' closest living genetic relatives—are extremely social, intelligent individuals who have rich mental and emotional lives. They have remarkable memories, share cultural traditions that are passed down through generations, care deeply for their families and friends, and grieve the loss of their loved ones when they pass away.

Sadly, hundreds of these remarkable beings are imprisoned in U.S. laboratories, where they are forced to endure decades of invasive procedures as well as fear, loneliness, and pain. This hellish experience leaves lifelong emotional scars, and many of them resort to self-mutilation or suffer from depression and other psychological disorders after experiencing the trauma of having their minds and bodies violated.

Despite international criticism, the U.S. remains the only nation in the industrialized world that continues to conduct invasive experiments on chimpanzees.

Many chimpanzees have been intentionally infected with diseases, such as HIV and hepatitis—even though scientists agree that they are archaic and unreliable models for researching human illnesses. The National Institutes of Health (NIH) recently stated that "research involving chimpanzees has rarely accelerated new discoveries or the advancement of human health for infectious diseases," and a landmark Institute of Medicine (IOM) report concluded that "most current biomedical research use of chimpanzees is not necessary." In response to the IOM report, NIH announced that it will cut funding for most invasive biomedical experiments on chimpanzees and grant sanctuary to at least 310 of the 360 federally owned chimpanzees currently imprisoned in laboratories.

While these trends are encouraging, hundreds of chimpanzees continue to be held in private laboratories, where they may be used in painful and deadly experiments, and NIH will continue to imprison as many as 50 chimpanzees for possible future use in invasive experiments.

Please help protect chimpanzees and other great apes now by using the form below to ask your congressional representative to work to ban all invasive experiments on chimpanzees and retire all federally-owned chimpanzees to sanctuaries. Putting your subject line and letter into your own words will help draw attention to your e-mail.
