No resource on earth is more precious than water. In one way or another, every living thing depends on it. Clear Choices: The Water You Drink examines the challenges to the world water supply and the impact they have on humans, animals, and plants-while discussing the far-reaching environmental, commercial, and political costs if those challenges are not met. Clear Choices is part of the Second Nature series. Each book examines environmental science from every angle-local, global, historical, and even personal. Young readers learn how to get to the heart of a problem, find out about people who are trying to solve it, and discover how they can get involved now...and in the future. The Second Nature series brings together teachers, scientists, authors, and editors to create a "team strategy" for exploring the most pressing environmental issues of our day. Book jacket.
