Mind mappers.

Includes index

"Every person, animal, and plant needs water to survive. We use it in our everyday lives in thousands of ways, so it might seem like there is an endless supply! But as the world's population grows, we are using more and more water, and if we don't properly care for what we have, we are in real danger of it running out... This book shows that we all have a part to play in making sure there is enough water for each one of us now and in the future."--
