@3, your bowling greens are not the problem. What are there, about a hundred in the entire US? Twice that, maybe? Compare that to more than 15,000 golf courses in the US -- a great number of them in deserts that get no rain -- more than 300 in Arizona alone. All of which are toxic chemical sinks. That's on top of all the homeowners.
You can no longer eat the oysters of Oyster Bay. Because of algal blooms from non-point-source pollution, aka fertilizers from Bremerton lawns. They should have an exorbitant tax on this stuff, and ban use on golf courses.

Wow... Thats more than $600 billion. Spent by just 15 people. On thier lawns! (Who are these 15 people and just how rich are they???)
