Part of the earth's largest surface freshwater system, Lake Erie is a vital source of drinking water for 11 million people. Researchers Anna Michalak, Tom Bridgeman, and Pete Richards are studying how farming practices and severe weather can increase the amount of fertilizer-derived nutrients in the water, which diminishes water quality and threatens the lake's ecosystem and the public's health.

Kansas farmers Stan Townsend and Mitchell Baalman and others that sit atop the Ogallala aquifer -- the largest freshwater aquifer in North America -- are pumping out water for crop irrigation far faster than natural seepage of rainwater can replenish it. Scientist David Hyndman from Michigan State University is helping develop a plan to better manage this vital resource for sustainable farming.

This video uses animation, graphics, and video clips to illustrate and explain each of the "flow" and "storage" processes in the Hydrologic Cycle, more commonly known as the Water Cycle: precipitation, interception, runoff, infiltration, percolation, groundwater discharge, evaporation, transpiration, evapotranspiration, and condensation.

Bernie Krause has been recording wild soundscapes -- the wind in the trees, the chirping of birds, the subtle sounds of insect larvae -- for 45 years. In that time, he has seen many environments radically altered by humans, sometimes even by practices thought to be environmentally safe. A surprising look at what we can learn through nature's symphonies, from the grunting of a sea anemone to the sad calls of a beaver in mourning.

Thierry Vrain retired 10 years ago after a long career as a soil biologist and ended head of a department of molecular biology running his own research program to engineer nematode resistance genes in crops. In his retirement career as a gardener he learned five or six years ago how the soil ecosystem really functions. He finds himself with a good knowledge of genetic engineering technologies surrounded by people in fear of being hurt by the food they eat. He found that he cannot ignore them anymore and has joined the campaign to educate consumers about the potential health problems reported in the recent scientific literature.

Now in his third year with the Vineyards at Chateau Hough, Mansfield Frazier has just received angel funding to kick off his next urban agriculture project, the BioCellar at Chateau Hough.
Remove the shell of any of the 15,000 abandoned homes in Cleveland that are beyond repair, and build a greenhouse over top, leaving the basement under the frost line, where mushrooms, selling for $12 a pound, can be grown in a hi-tech BioCellar to grow crops, create jobs and reuse the land, for a triple net bottom line.
