Water keeps us and our world alive. Without it we couldn't exist. Water and climate influence every aspect of human life. They affect where and how we live, our health, farming and food, our energy and our industry. The world's climate is changing. The amount of water we use is changing and the population is growing. But water is finite. There is only so much of it to go round, and we cannot make any more of it. This book is one in the Question It! series for readers upwards of age 10, which explores globally important topics relating to the environment in a balanced and objective way, encouraging readers to adopt a questioning approach to the issues involved. Titles in the 6-book series are: Climate Change, Food, Natural Habitats, Oil, Population and Water.
