傷だらけの天使 ニナちゃん（Wounded Angel Nina-chan）　旭山動物園　チンパンジー　202306

This channel is a video that discusses the fascination of great apes (#gorilla、#chimpanzee、#orangutan) and enrichment. Apes are the most intelligent animals and are therefore susceptible to mental illness. Environmental enrichment is a measure to reduce mental and physical stress and lead a happy life from the standpoint of apes, not from the convenience and emotions of human beings.
