I got several e-mails in response to my story earlier this week about Whole Foods eliminating plastic bags from its stores by this spring. But the most interesting thing to cross my inbox was a note from a company in Colorado that focuses on environmentally friendly lawn care. Clean Air Lawn Care is looking for franchisees in our area, so the service may be available here soon. But I have to say the most intriguing part of the company's Web site is the "Clean Lawn Calculator." All you do is plug in your state and the square footage of your lawn and the calculator tells you how much pollution you generate by taking care of your lawn. If you want to check it out, go to Clean Air Lawn Care's Web site and click the link at the bottom for the calculator.
