The development of agriculture introduced trading and surplus. This allowed people to expand the way of living and trading. People were able to store food by digging holes within the ground.
Once hunters and gatherers learned about the conveniences of nurturing crops specifically to help them grow and to use them for food sources, they stopped going after every animal to feed everyone in the village and instead created crops. Thanks to the Green Revolution, productivity in the agricultural field has greatly increased and less manual labor is required. I hope I help! ^^
