Water: The Lifeblood of Nature

Water is vital to our planet. In fact, 71% of our Earth is covered by water. Rushing rivers, soothing oceans, active wetlands, and even the water you can’t see, all contribute a healthy functioning ecosystem. National Parks feature some of the most pristine waters in the U.S. Since water is so vital to both people and nature, we must preserve it for future generations.
