Water, Water Everywhere…
• “Water, water everywhere, but not a drop to drink.” Huh?!
• There is a lot of water on planet Earth. BUT…– 97% of it is in the oceans– 2% of it is locked in glaciers – leaving approximately 1% for all of the land based
plants, animals, and 6.5 billion humans to survive on
