Thanks for your thoughts. I believe there is actually a lot land that is currently being used to grow grains (corn, wheat, soy, etc.) that could be turned into pastures to raise healthy animals. Regarding the idea of eating animals, evolution shaped that one. Look at where eyes on a human being sit... on the front of the head, not the side, such as in the case of a zebra or cow. Humans are predators, not prey animals. However, I believe in the future we will be able to bypass these innate processes with cultured meat. I am part of an organization that is carrying out research on stem cells and their applications to growing meat in a lab. It is only a matter of time before this science goes mainstream.
