It is related to people because it changes how they live. If you live in the mountains it is different than how you live in the cities. You might get water from the river or go hiking a lot if you live beside or in the mountains.
The environment also changes because if you live in the mountains or beside it, it would be cooler because the altitude is higher. Also the air there would be cleaner because of the many trees surrounding you.
