Captive elephants have complex needs that few facilities can meet, with sanctuaries providing better welfare than most zoo environments.
Elephants represent perhaps the clearest case where welfare in captivity is extremely difficult to achieve. Their intelligence, social complexity, and physical needs - including extensive movement and species-appropriate social groups - cannot be met in most zoo environments. The documented prevalence of foot disease, stereotypies, and behavioral signs of psychological distress in zoo elephants supports this conclusion. Sanctuaries providing large naturalistic environments provide substantially better welfare for elephants unable to be returned to the wild.
