What kind of ecosystem evolves to survive fire, brutal winter temperatures and decades of drought? For thousands of years the grasslands of North America thrived under such conditions, existing in an intimate relationship with the earth.
In GRASSLANDS, archival film footage shows how farmers paid the price for displacing the perfectly-adapted ecosystem with monocultured, imported crops. Under a persistent drought in the 1930s, millions of tons of topsoil blew away in the prairie wind, resulting in the devastating dust bowl.
GRASSLANDS examines the plants and animals which live in complex interdependency on the remaining tracts of native grasslands, and shows how lessons learned can provide valuable knowledge for modern, sustainable agriculture.
