Although water covers more than 70% of Earth's surface, two billion people don't have enough fresh, clean water for drinking, washing, cooking, and growing food. Even in countries where there are good water resources, the water cannot always reach the people who need it. One of the reasons for water scarcity is climate change. On average, temperatures are higher than they were in the past. In some places, there is also less rain, so there isn't as much water in lakes and rivers. Water scarcity affects people in different ways. Farmers, for example, can't grow as many crops as they used to. Without crops to sell, they can't earn enough money to pay for clean water. A lack of water can also mean that people have to walk a long way to find it, which can have a negative effect on their health. The biggest impact can be on children, who have less time to spend in school. Another problem is that people often can't find clean, safe water. The dangerous metals and bacteria in dirty water can make them very ill. This can be more dangerous for children than for adults because their bodies are less able to fight the illnesses. Solving the problem of water scarcity is not simple. However, there are lots of things that can help such as finding new water sources and developing new technologies to produce and clean water. It is also important that people who live in countries with plenty of water don't use too much of it. The worst thing that could happen is that no action is taken, and more people suffer. 58 3 Read again, and answer the questions. 1 How many people around the world don't have enough water? 2 What is one of the reasons of the water scarcity? 3 What can't farmers do when there isn't enough water? 4 Why can water scarcity cause children to spend less time in school? 5 Why can drinking dirty water be worse for children than adults? 6 What can help solve the problem of water scarcity?
