This series uses familiar local features to illustrate environmental issues on a global scale, linking everyday activities and environmental problems. It also deals with ways of solving the problems and offers suggestions for activities, projects and experiments. In this book the author discusses why drains are necessary, what goes down them every day and the effect they have on the environment. She investigates how poor sanitation can cause disease and how water supplies, rivers and marine ecosystems become contaminated by household, garden, industrial and farm waste which is poured into drains.
