Orangutans are critically endangered due to rainforest destruction driven largely by palm oil expansion. Their welfare is threatened at both the population level - through habitat loss - and the individual level through poaching, orphaning, and the wildlife trade.
Orangutan welfare is threatened across multiple contexts. In the wild, habitat fragmentation forces orangutans into smaller, increasingly food-poor fragments with elevated stress and reduced reproductive success. Animals caught in the path of land clearing are killed or injured; mothers are killed so infants can be captured for the pet trade. Orphaned orangutans in rescue centers face years of intensive rehabilitation - a welfare challenge in itself - attempting to rebuild the forest skills that should have been learned from their mothers over a decade. In poorly managed zoos and private ownership, orangutans develop stereotypic behaviors, depression, and cognitive stagnation from environmental impoverishment. Their intelligence makes the welfare cost of deprivation particularly acute.
