Not only is it much easier to raise animals in a more humane manner than is done industrially, when people live closer to their food source they understand the sheer amount of resources -- land, water, deforestaton -- that goes into every kilogram of meat. I think people would eat a more reasonable (i.e. a lot less, and healthier) amount of meat if they saw and experienced the impacts of meat farming first-hand, from cutting down trees to create land, treating the land for farming enough food for the animals to grow before you can kill them for meat -- rather than selecting "beef" on a food delivery app without thinking about anything.
