Water may be consumed either by its withdrawal and use or by being made unusable by pollution. Choose one of the following-
1. Choose a particular water pollutant or cause of water pollution and explore the ramifications it has for water supply. You might consider human health issues, industrial uses, or ecosystem impacts but be specific.
2. Choose an area of the world that currently faces a water supply issue. Provide a brief overview of the causes for the supply issues. Now using that knowledge look around the world for an area that does not yet have serious supply issues but may have them in the future for the same reasons.
