In addition to the water you drink, you use about 100 gallons of water every day—for washing, cooking, and many other things.
A hundred gallons is about the same amount of water used in four five-minute showers. If you count the water needed to manufacture goods and raise and produce food, the amount is even greater. For example, it takes about 150 gallons of water to grow and produce one loaf of bread or to make enough paper for one Sunday newspaper. It takes over 39,000 gallons of water to make one new car. Every year, the population grows, and we need even more water. Yet, Earth has only so much water, and we have no way of making more. As a result, we must conserve what water we have.
