re the water cycle pay attention mitakuyapi "Sustainability: Water" starts out with a tutorial on the global water cycle, which transports water through the air, land and seas. The series takes a closer look at the places in America where worries about water are already rising: The Ogallala aquifer, where farmers in Kansas and other states are pumping out water for crop irrigation faster than it can be replenished. The Sierra Nevada mountain range, where scientists have set up wireless sensors to monitor the snow pack and the snow melt. The Rocky Mountains, where the damage done by bark beetles is imperiling a watershed that supports more than 60 million people in the West. Los Angeles, where researchers are studying how the water supply can be made more sustainable and less dependent on snow melt "imports" from hundreds of miles away. Chesapeake Bay, where the watershed for Baltimore is endangered due to nitrate pollution in run-off from a variety of sources. Lake Erie, an important source of drinking water that suffered an unprecedented bloom of toxic blue-green algae in 2011.
