Two links contained in Are you a carbon bigfoot? I sure am, sad to say by Harry Fuller of Webware are a pretty eye opening exercise. Think you are doing all you can to limit your impact? Try these two out and see how you fair:
Harry’s honest self assessment:
Altogether these sites are: depressing, educational, geared to getting you to do something about your consumption patterns. Turn off your work computer when you are done for the day (or night). Carry your own shopping bags. Use alternative energy when possible. Use efficient bulbs and appliances. Walk more. Freak out over air travel. All good advice. And aimed at making each of us less of a carbon bigfoot.
