Agricultural trade associations have long asserted that animal welfare laws are a bad idea because farmers and ranchers know best how to take care of their animals. We heartily agree. In our experience, the people who work with farm animals every day have the best sense of what is needed to ensure their welfare and the knowledge of how welfare can be protected in practice. But good animal husbandry is literally impossible in industrial set-ups.
