Everyone needs the things Earth can give us - such as air, water, shelter, food and energy. But we must learn to use these carefully, without harming the world around us. Our Earth is in danger - and we must make it safe for the future.
Most of the world's fresh water comes from rivers. We need fresh water every day. This book tells you about rivers as highways for ships, and about water wildlife. It also helps you find out about keeping rivers clean and healthy.
