Water is life. Every living thing depends on water: people, plants, animals and trees. Water is easy for most of us in this country to get. We turn on the faucet and out comes water. Water covers three quarters of the earth’s surface. While it sounds like we have a lot of water, most of our water is in the oceans and ocean water is too salty for us to use. All living things need fresh water. Only about three percent of the water on Earth is fresh water. Since some of that fresh water is frozen in the ice caps and some is too far underground to use, only about one percent of the fresh water on earth is available to us. Therefore, water is limited and precious.
We use water in many ways. Farmers use water to irrigate crops. Ranchers use water for their ani-mals. In our daily lives, we use water for a variety of things including drinking, washing hands, brushing our teeth, cooking, and bathing. We also use water for recreation.
