I support this, and I suspect a more practical thing is that humane slaughterhouses will gain in popularity. A lot of the problem in our current era is how thoroughly you can outsource the job - but humanity has a large history of farmers/ranchers/hunters and their community being entirely willing to eat meat. Also, this is what kosher/halal rules about slaughtering are trying to do. (There is some debate about how effective those specific rules are.)
