As Annie stated earlier
, today is World Water Day. This year's theme is "Clean Water for a Healthy World."
Although we live on a water-covered planet, only 1% of the world's water is available for human use, the rest locked away in oceans, ice, and the atmosphere. Here are 15 images from National Geographic, along with a collection of other photos from news agencies and NASA. The Big Picture
is on the scene.
