The long and the short of it is to manage to prohibit the very poor or the very ambitious (poachers) from hunting otherwise non-food wildlife and bush meat. Humans have had relationships over millennia with ungulates (deer, elk, moose, sheep, goats, etc.) but a lot of other animals are still unusual food and have diseases that can jump. (And hunters still have to be careful with deer, etc. with some parasites, disease, etc.) Tough to do in a world where "civilized" people profit by trying to sell the N-95 surgical masks and wildly inflated prices. Greed is everywhere. So is hunger.
