It’s not just the water you drink or wash with. It includes all the water needed to make the things you use, grow the food you eat, and make the clothes you wear. Water footprint matters because many places in the world face water shortages. 2.2 billion people don’t have safe drinking water, and many people waste water every day. This makes the problem worse. You can reduce your water footprint with simple changes. First, don’t waste food. A lot of water is needed to grow, clean and cook food. Second, change how you use water: take short showers instead of baths, turn off the tap while brushing your teeth, and collect water from washing rice to water plants. Third, choose carefully when buying clothes. Cotton needs a lot of water to grow, so making jeans uses a huge amount of water. Small changes add up. If everyone reduces their water footprint, we can help save water for everyone. 1. What is a water footprint? A. Only the water you drink every day. B.
