What's so important about water? Water is necessary for life; humans and animals require water to survive and agriculture depends on it. Despite its importance, it's also a scarce resource. This book introduces readers to the water cycle, ways we use water each day, and how water scarcity is a worsening problem. Readers will also learn what they can do about this problem in their daily lives, by turning off water when brushing their teeth or replacing their bath with a shower. Fascinating facts and graphics will give readers a strong connection to the issue and allow these little eco experts to save water in unexpected ways.
