That question gave birth to the modern movement. Its goal is not to abolish the use of animals but to minimize their suffering. Welfare advocates fight for larger cages, humane slaughter, environmental enrichment, and pain relief. They operate on a pragmatic bargain: humans will continue to use animals, but we must do so with a moral floor. The five freedoms—freedom from hunger, discomfort, pain, fear, and the freedom to express normal behavior—are its secular commandments.

The public, meanwhile, lives in the messy middle. Polls consistently show that an overwhelming majority of Americans oppose factory farming. Yet meat consumption is rising globally. We watch heart-wrenching documentaries ( Blackfish, Dominion, Seaspiracy ) and then order the cheeseburger. We buy “humanely raised” labels while ignoring the fact that even the best-certified broiler chicken lives about 42 days, reaching slaughter weight at seven weeks—an age at which a natural chicken would be a fluffy adolescent.
