Water Quantity<\/h1>\nEven though the earth contains an abundance of water, only a small percentage is fresh water. An even smaller amount of this freshwater is accessible to the people and animals that need it. As the human population grows, the amount of freshwater available per person shrinks. The relatively small amount of available freshwater demonstrates how critical it is for everyone to help maintain clean, healthy lakes and streams.<\/p>\n
