Legal frameworks governing zoo animal welfare vary enormously between jurisdictions, from comprehensive welfare-based licensing systems to minimal regulations focused only on public safety.
Legal frameworks for zoo welfare matter enormously because they set the floor below which no facility may fall, and determine whether poor welfare can be tolerated or must be corrected. Strong legislation combined with competent enforcement provides the scaffolding within which the zoo industry can self-regulate upward. Without this foundation, voluntary accreditation schemes cannot reach the many substandard facilities that harm animals while presenting themselves as legitimate zoos.
