The world's population is growing, and with this growth comes an increased pressure on the resources, such as food, water, land for housing and energy sources, we need to live. The way in which humans are treating the planet they live on is having a significant effect on the global climate. This matters because the future of life on Earth, no less, depends on our understanding of the problem and the actions we take. This book, in the Question It! series for readers upwards of age ten, will explore these important topics in a balanced and objective way, encouraging readers to take a questioning approach to the issues surrounding the global population.
