Why did people have to settle down and live in one place ?

Question

Why did people have to settle down and live in one place after they had discovered farming?

Answer 1

because with farming there's a season to plant and a season to harvest. that would be impossible if they kept moving. staying in one place with farming is easier too because when they were nomads they were following the animals. being settled down all they have to worry about is when the soil becomes poor.
