Sustainable Water 

Shortage of good quality fresh water is a global problem second in importance only to global warming. Human activities are already withdrawing nearly half of all fresh water reasonably available. Even in Canada, a water-rich nation by any standard, lack of quality control for drinking water has caused death and illness in several communities; some provinces suffer chronic shortages of water for agriculture; and almost everywhere capital costs for infrastructure to supply fresh water and to treat wastewater water are growing.
