Animal welfare legislation exists in most countries but varies enormously in scope, species coverage and enforcement, creating a patchwork of protection that leaves billions of animals unprotected.
Animal welfare legislation that exists on paper but is not enforced provides no welfare benefit. Enforcement requires resources, political will and trained inspectors. Species exclusions — particularly of fish, crustaceans and insects — leave the animals present in the largest numbers entirely outside legal protection. The gap between legal minimum standards and science-based best practice means that legal compliance does not equal good welfare. Strengthening and enforcing existing law is as important as expanding its scope.
