ia, and Africa during the mid 1990s. However thanks to improvements and advances in sanitation this disease has mostly been wiped out. Another factor in these developments is a greater awareness of how to conserve and recycle water. Since the 1980s demand for water has actually gone down due to awareness. Individuals and communities are better equipped to save water and they have learned to be less wasteful. The focus has returned to concentrating on basic needs for the human population and the environment. Even though there are serious efforts being made to create water for everyone experts are not sure if the water supply can keep up with a population that is growing as fast as ours is. It has been estimated that by 2025 forty percent of a population numbering 7.2 million may face serious problems if only natural sources are available to them. Agriculture, industry, and general human health will be challenged by high demand. Even though we are at a point where the water supply is being sustained surging future populations around the world are already putting stress on a limited supply. The article also states that human health is not the only thing in danger. By creating dams, and canals damage is caused to animal and human habitat.By far the most casualties have been in the numbers of fish. Populations of freshwater and saltwater fish have been greatly effected. In the United States alone 95% of the juvenile salmon population did not survive the migration to the ocean because of dams and reservoirs along the Colombia and Snake Rivers. The population of Atlantic Salmon has fallen to less than one percent of its original number. The major factor was the 900 or so dams on New England and European rivers that block them from their reproduction grounds. Although more drastic than any other situation is the one in the Aral Sea which is located in central Asia. The two main rivers that flow into it (Amu Darya and Syr Darya) have been diver...
