Take a Monkey to Lunch Day is celebrated every July 21 in the United States, focusing on raising awareness for non-human primates such as monkeys, apes, tarsiers, and lemurs. The day aims to highlight the challenges these species face and promote conservation efforts. Participants are encouraged to educate themselves and others about primate welfare, support ethical wildlife tourism, and donate to reputable primate sanctuaries. Organizations like the World Wildlife Fund, Jane Goodall Institute, and Dian Fossey Gorilla Fund often lead initiatives related to primate conservation on this day. Social media engagement is encouraged, with hashtags like #TakeAMonkeyToLunchDay to share facts and promote awareness. Retailers known for animal welfare may also participate by promoting cruelty-free products or donating portions of sales to primate-related causes.
