International Primate Day
This day is dedicated to saving and protecting primates of all species including chimpanzees, monkeys, orangutans, gorillas and many more. Animal Defenders International (ADI) established Primate Day in 2005 with a specific focus on ending experiments on monkeys for disease research. According to the International Union for Conservation of Nature (IUCN), more than a third of primates are considered critically endangered or threatened species.
