Hold Your Water: 68 Things You Need to Know to Keep Our Planet Blue

Written by Bob Wyland of the Wyland Foundation - they are all about protecting oceans, waterways, and marine life. Mr Wyland is also an amazing painter - just take a look at his whaling walls.

This book is a quick and easy read and gives all sorts of suggestions (more than 68 actually) for conserving and preserving water, not to mention all kinds of facts about water - such as these:

Two-thirds of the world is covered by water - 97.5% of it is undrinkable seawater. Of the remaining 2.5 percent, nearly two-thirds is in polar ice caps, and the remaining third is ours, except half of it is considered polluted by most international standards, 20% is in remote areas, and most of the rest comes as monsoons or floods. Therefore, the amount of fresh water available for human use is less that .08% of all the water on the planet, and 70% of that .08% is used for agriculture. The demands of energy and industry for water is continuing to grow, and in the next two decades, human use of water will increase 40%, and 17% more water than is available will be needed to grow food.
