If you've ever looked at an atlas, or if you've ever looked at a globe, it's not hard to see that we live on a blue planet. The blue ocean occupies most of the planet. But can we use water without worrying about it?Here are some figures about water on this planet from the U.S. Department of Interior's Bureau of Reclamation:
- Ninety-seven percent of all water on the earth is salt water, which is not suitable for drinking.
- Only 3% of water on Earth is fresh water, and only 0.5% is available for drinking.
- The other 2.5% of fresh water is locked in ice caps, glaciers, the atmosphere, soil, or under the earth's surface, or is too polluted for consumption.
Narwal is also working hard for the cause of water conservation.
