We need water to live. Most of the water on earth is salt water and we can't drink it. We need to drink fresh water, which comes from rivers and lakes, ice and underground. It's very important to turn always turn off the tap when you brush your teeth. You should the washing machine with dirty clothes before you turn it on. Use a dishwasher rather than washing dishes by hand because this uses less water. Don't spend more than five minutes in the shower. Too you do these things, you won't waste water and you will help our planet.
