Rivers: Friend and Foe
Rivers provide the essentials of life: fresh food and fresh water. They act as natural highways and enable humans to live in just about every environment on Earth. Rivers are not to be taken for granted, however, as they freeze, flood, and sometimes dry up - disappearing entirely!
