Humans thrive near water, as they do along the Nile River.

Detailed Description

People live near freshwater

All life needs freshwater to survive and thrive. From microbes to dinosaurs in ancient times to people in the present-day world, freshwater is needed for all things involved in living. It is no surprise then that since the times of early humans, they established their living areas along or next to freshwater bodies. There is no better proof that that is still true today than looking at this composite satellite photograph of all the Earth at night and noticing the Nile River in Egypt. From Cairo southward, along the river, in the desert, there are lights of human habitation.
