Document Summary
Chapter 11 freshwater systems and water resources y they fear that we will place our sovereignty at risk if we allow large-scale diversions of freshwater, or bulk water exports from canadian water bodies. Once bulk water exports are allowed to begin flowing to the thirsty southwestern united states, they maintain, they will be impossible to stop. Interbasin transfers is the transportation of water from one drainage basin to another. y. Freshwater systems y freshwater is pure with dissolved salts (most is in icecaps, glaciers and underground aquifers). y 97. 5% of water is in ocean and 2. 5% is fresh water. In the 1960s, atmospheric scientists began wondering why their measurements of stratospheric ozone were lower than theoretical models predicted. Researchers hypothesizing that natural or artificial chemicals were depleting ozone finally pinpointed a ground of human-made compounds derived from single hydrocarbons, such as ethane and methane, in which hydrogen atoms are replaced by chlorine, bromine, or fluorine.
