Why was agriculture necessary to the development of civilizations?
What will be an ideal response?
Before a civilization could exist and prosper, it first had to have a strong agricultural
system. When people had to spend all their time hunting and gathering food or trying to
grow food, they had little time for anything else. Efficient agriculture allowed fewer
people to raise the same amount of food for the population. Therefore, other people had
time to protect the population, create works of art, construct buildings, and so on.
