Large numbers of chimps have been trapped to be sold to zoos,circuses,pet stores,and laboratories. Chimps bred in captivity have reduced the need to trap wild ones. Many educational experiments have been done with young chimps in captivity. You already read about chimps taught to speak with sign language,but did you know some have been taught to communicate with special computers? Their problem solving ability is second only to yours. They can imitate our behavior so perfectly sometimes that it's astounding.
