What would have happened if agriculture hadn't been invented?
Obviously mankind would probably not have survived. There are not enough wild animals to provide for food. And the domestic animals need vegetation to eat.
Take the South for example: farmers grow corn not only for their own consumption, but also, to feed the hogs. Then the farmers eat the ham and bacon, hopefully with fried eggs (:
Notice in Genesis God made the plants before the animals so the animals could eat.
AGRICULTURE MADE AN ANIMAL HUMAN. With agriculture started setteled life which developed association of people, Hamlets, villages and human society. Agriculture is co evolution of selected plants ( our food and other crops) and human beings.
