Lawns don’t offer much to the environment, but they are great things on which to walk, play Frisbee, and roll Easter eggs. If you want to protect the environment, however, you’re going to have to end your lawn’s dependence on chemicals. Much of the chemical fertilizers and pesticides applied to lawns are carried off by the rain into groundwater, streams and rivers, causing harm to plants and animals in the surrounding environment. (Herbicides, pesticides, and other poisons have no place in the eco-friendly garden.)
The good news is that these chemicals are not essential.
