Americans spend so much money and time on their lawns, you'd think we either eat or sell grass. More land in the United States is planted in turf--32 million acres--than in corn. The typical American lawn sucks up 10,000 gallons of supplemental water (non-rainwater) annually.

What's worse, the U.S. Environmental Protection Agency estimates that about 80 million U.S. households dump nearly 90 million pounds of herbicides and pesticides on lawns in a year. In fact, lawn care is as much of a danger to our health and the environment as conventional agriculture is.
