For example, I wet my toothbrush, turn off the water, brush, and then turn it on again to rinse. I also take short showers instead of long baths. A bath uses much more water. These small actions save a lot of water every week. It is important because water is a limited resource. Part 2 A water footprint is not only the water you drink or wash with. It also includes the water used to grow your food and make your clothes. For example, a hamburger needs a lot of water to produce. You should care about your water footprint because many people do not have enough clean water. By reducing your footprint, you help save water for everyone. Part 3 Growing food needs a lot of water. If we buy more food than we need and then waste it, we also waste all the water used to grow that food. For example, throwing away a banana means wasting the water that helped the banana tree grow. So we should only buy what we will eat. This is an easy way to save water without changing our daily habits. 1 学科网（北京）股份有限公司 $
