Yong, a six-year-old pigtailed macaque rescued from a life harvesting coconuts, gets a vasectomy at the Wildlife Friends Foundation hospital in Phetchaburi, Thailand. The organisation is working with authorities, the coconut industry and exporters to encourage farmers to stop taking monkeys illegally from the wild and using them as labour, and switch to shorter trees that are easier to harvest. They are giving Yong a vasectomy so he can join a mixed troop of rescued monkeys without risk of breeding
