That means it's time to take care of crops and gardens. Switchgrass takes care of you and the environment on today's EnvironMinute. Switchgrass is a type of prairie grass that grows 12 feet tall. It once covered the American plains like an ocean. It turns out that switchgrass is a promisng fuel additive.
Energy companies can add clippings to their coal-fired power plants to reduce toxic emissions.
Those power plants give off chemicals that cause acid rain, ozone depletion, and smog, not to mention global warming. The switchgrass may be able to help that. The EnvironMinute is produced in cooperation with the National Safety Council and made possible by the Teresa and H. John Heinz III Foundation.
