Environmental Problem - Water Shortages - Essay ExampleJury and Vaux (2007) posited that if the present rate of water consumption continues, the situation of water dearth will only get worse. They went on to postulate that by the year 2025, over two-thirds of the worlds population will most likely be faced with the challenge of water shortages. The worlds ecosystems will also be significantly affected as a result of the shortages. Water befoulment comes from many sources, and this renders the water unusable or reduces the amount available for use.

Indiscriminate application of these chemicals ends up polluting not only the lands where they are used but also water sources as they are washed into the nearby streams and waterways (Chaturvedi, 2000).
