The relationship between humans and the environment is a two-way street. On the one hand, the environment in which people live can do a great deal to shape their societies. On the other hand, people have always been able to change their environments for better or for worse.
Societies are shaped to some extent by environment. People who live in a jungle have different ways than people who live in deserts. The places where the first civilizations arose were determined by the availability of water and of plants and animals that could be domesticated. In these ways, the environment affects people.
But people affect the environment as well. This is especially true today when there are so many more people in the world than in past times. People can harm the environment (global warming, for example) or help it (conservation).
