WATER,WATER The planet Earth is mostly water. Oceans cover the biggest part of it- and there are lakes, rivers, streams, and even water underground. All life on Earth- from the little bug to the biggest whale- depends on this water. It’s precious. But we are not doing a very good job of keeping water clean. In many places the water has become polluted.

RIVERS AND LAKES Rivers and lakes are polluted by garbage, or by poisonous chemicals which are dumped right into them. Half of the lakes in the world are polluted.
