“All things are water.” – Plutarch   Water surrounds us. Falling from the sky, collecting in lakes and rivers and streams, quenching our thirst, nourishing our food sources—water is the critical building block of life. Known as the “Blue Planet”, about 70% of Earth’s surface is covered with water. With this finite resource being so fundamental to our survival, one must wonder why so many of us don’t even know where our water comes from. The Water Book provides a comprehensive look at why water is so important, an overview of the dangers our water supplies currently face, and what we can do in our daily lives to help ensure clean, safe water for the future. The Water Book is simple and easy to read, inspiring and informative. Readers will be guided and empowered to make changes in their own lives to help preserve and protect Earth’s precious water supplies. —Alexandra Cousteau
