National Geographic: Freshwater

Is there a water crisis? The United Nations states that "water use has grown at more than twice the rate of population increase in the last century." This thorough site provides plenty of information on the use and conservation of fresh water, including a way to calculate an individual's fresh water foot print and a game to help young students learn about water use and conservation. By conserving fresh water, we not only protect ourselves from disaster, but also protect the wide diversity of animal and plant life that rely on all kinds of freshwater wetlands around the world.
