According to the World Water Development Report as discussed in the 12 March 2009 Globe and Mail, the global water shortage is worsening (http://www.theglobeandmail.com/servlet/story/RTGAM.20090311.wwater0312/BNStory/International/home). Causes include pollution, climate change, population growth, and changes in eating habits and resulting agricultural needs (ibid). Besides hurting food supplies, the water shortage also stunts economic growth, and could aggravate political instability in countries and regions already in conflict (ibid). There are some areas that do not have clean water or efficient sanitation (ibid).
One thing unmentioned in the article is the amount of water used by power plants. There is a way to produce clean, emissions-free energy without using water. If water wasn’t needed for energy production, there would be much more for agriculture and other needs. This clean, emission-free energy production will drastically cut pollution levels, improving the climate and the water. This production will also be used to clean water in still-polluted areas, and get clean water to areas that needed it for the basic necessities of living, agricultural production, and manufacturing.
