The idea of planting crops significantly affected people primarily by allowing them to stay in one place, rather than migrating for food. This shift from a nomadic lifestyle to a more settled agricultural lifestyle marked the beginning of the Neolithic Revolution. As people began to cultivate crops, they could produce surplus food, which led to the establishment of permanent settlements, the development of communities, and eventually the rise of civilizations.
This agricultural lifestyle contributed to various societal changes, including population growth, the development of trade, specialization of labor, and the formation of complex social structures. While some groups may have migrated or adapted to new agricultural practices in different environments, the general trend was towards sedentism and the establishment of stable communities. Therefore, the correct answer to the impact of crop planting on people is that it allowed them to stay in one place.
