Elephants are among the most space-demanding animals kept in zoos, and evidence consistently shows that current enclosure sizes in most institutions are insufficient for good welfare.
The evidence that most zoo elephants suffer from foot pathology and stereotypic behaviour - consequences of insufficient space and social complexity - is overwhelming and well-documented. The debate is no longer whether current zoo conditions are inadequate for many institutions, but what the appropriate response is: improvement in facilities and standards for accredited zoos, or a phase-out of elephant keeping below a welfare-viable scale. Some leading institutions have invested in large, naturalistic facilities that produce better welfare outcomes. Consumer support for accredited institutions with transparent welfare reporting drives continued improvement.
