Here's a comment I sent on the New York Times story on the recent algae bloom in Lake Erie.
"One small measure that would help -- a ban on residential use or application of pesticides and fertilizers. Lawns are wonderful, but they would grow just fine without sprinklers, fertilizer, herbicides, or pesticides if we followed the practices of a generation or two ago. To improve the lawn, add a handful of clover seeds in the spring or fall to fix nitrogen that helps sustain the grass. Mow regularly but not too often. We are ruining our shared environment to outdo our neighbors for perfect lawns."What's on your lawn?
