Captive elephants require complex social groups to meet their welfare needs, yet many zoos house them in pairs or even individually.
The social needs of elephants are so extensive that most zoo facilities simply cannot meet them. Solitary or pair-housed elephants develop stereotypic behaviors, poor health, and shortened lifespans. Large sanctuary environments with suitable social groups and ranging areas provide substantially better welfare. The zoo industry has struggled with elephant welfare precisely because meeting their needs requires more than typical zoo spaces allow.
