Water covers three-fourths of the surface of our "Blue Marble." The water cycle keeps it moving from the air to the ground and back again. Too much water coming down too soon can trigger floods, while not enough of it for too long brings drought. While most of the hydrosphere's water is found in the oceans, it's also in lakes, rivers, streams, aquifers, and even puddles and cracks in rocks. Wherever its found, much of our precious "liquid gold" has been polluted by runoff from cities, farms, and factories. Planet Diary chronicles the battle to restore our oceans and waterways to good health.
