There are many ways it could be done more humanely

Now, I don’t believe that humans were never supposed to have consumed animals or used their by-products. We needed to, for shelter, food, tools, and much more. Some cultures still need to for survival. But I believe that as humans become more humane, and despite all the evil deeds that still go on in the world, we have evolved and it’s part of our path to move away from animal products. Maybe we’re meant to use some animal by-products—eggs and milk and wool (though dairy has the protein casein, a proven cancer promoter)—but to do it without cruelty could perhaps only be accomplished on a small farm. The size and needs of our society make it difficult to meet demand. But still, there are many ways it could be done more humanely, even with mass production, though the agriculture lobby is strong and resistant.
