Grass ain't greener : organic lawn garden care / by Kevin & Shamil Cole.

"Our lawns have become a major player in our eco-system, after all it covers about 50 million acres in just America (2003 estimate). That means what you do is multiplied thousands of times over, every day in our country. So it's important that you do things right and stop flying by the seat of your pants just because that's the way you've always done it. Besides keeping your house from sinking into some dark abyss, your lawn is an important part of our environment. Environmentally, turf grass reduces carbon dioxide emissions, mitigating the heat island effect commonly found in our urban environments."--Back cover.
