Now they're figuring out that they can in a sense grow animals. They can breed animals. We can have cows for milk. We can have larger animals like oxen for traction to pull our plows and help us grow more food. Not to mention sheep and wool and using pigs and all different types of byproducts of animals. But the most probably important thing is going to be milk and that milk is going to really create a source of nutrition and protein for people. And if you don't believe me look at the numbers of lactose intolerant people that kind of disappear off the planet during the Neolithic Revolution through evolutionary survival.
