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 incredible memories, they share cultural traditions that are passed down through generations, they care deeply for their families and friends, and they grieve the loss of their loved ones when they pass away.

Sadly, more than 900 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 on chimpanzees, 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 of them 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, an NIH committee recommended cutting funding for most experiments on chimpanzees and stated that "the majority of NIH-owned chimpanzees should be designated for retirement and transferred to the federal sanctuary system. Planning should start immediately." 

Please help protect chimpanzees and other great apes now by using the form below to ask your congressional representative to work to ban 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.
