What cycle does water go through? What pollutants can it gather along the way? What are the sources of water pollution? Who treats our water? Is water a public good or a commodity? Where does bottled water come from? Is it better than tap water? What happens to water in countries that don't regulate its quality or can't afford to treat it? What innovations allow for the affordable collection and treatment of water? We will ask those questions through this unit, and attempt to answer them. The 2008 award winning documentary FLOW by Irena Salina will be the base for our conversation on issues surrounding water conservation:
