The Shrinking Aral Sea
Fertilizer and pesticides went into the Aral Sea. The lake had a good fishing industry, but the pesticides damaged it. The pesticides and fertilizers destroyed the habitat of many plants and animals. They also threatened human health. Since the fishing industry went down, many boats were left in the middle of the lake. Now they're in the middle of a desert.
Kazakhstan built a dam to save the North Aral Sea in 2005. The World Bank helped. The North Aral Sea has gotten bigger and fishing returned to it. The south side, however, is almost completely gone. Most of the land there is semiarid or arid. Those areas are usually good for farming, but there is too much salt in the land to grow anything.
