Orang-utans face existential threat from palm oil plantation expansion, with individual welfare impacts from habitat destruction, rescue, and rehabilitation.
Orang-utans encountered by plantation workers are sometimes killed or captured. Orphaned infants found near dead mothers experience profound psychological trauma. Rehabilitation of rescued orang-utans requires years of intensive care before return to forest. Habitat destruction forces orang-utans into human-inhabited areas where they face lethal conflict. The welfare of individual orang-utans is inseparable from the conservation of their forest habitat.
