Saving Lake Chad

United Nations, New York, April 2009 - 21st Century Show. Lake Chad is now one-fifth of its original size, partially due to changes in climate and human activities such as improper farming methods and over-fishing. By the year 2020, an estimated 35 million people will depend on Lake Chad for their survival. A project to replenish the lake is underway, but its funding is still far from certain.
