Answer:

1.Dams are built to provide water for human consumption, for irrigating arid and semiarid lands, or for use in industrial processes. ... Many dams are built for more than one purpose; for example, water in a single reservoir can be used for fishing, to generate hydroelectric power, and to support an irrigation system.

2.Every person on earth needs water to survive. Without it, many of us would get sick and even result in death. ... Conserving water is important because it keeps water pure and clean while protecting the environment. Conserving water means using our water supply wisely and be responsible.
