Sustainable Dave, as he's calling himself in his newest venture, spent 2008 attempting to produce as little trash as possible without drastically altering his lifestyle. He chronicled his efforts on his previous blog, 365 days of trash. He didn't just log his trash for the year, he kept it in his basement and weighed it in January. Just about 30 pounds, not bad. According to sustainablog, he did all this while still eating his favorite junk food.
The only drastic measure he took was starting a worm bin to dispose of food and paper scraps. I'm not sure why I'm all hung up on trash here. I guess I feel it's not getting enough attention in the current green hysteria. I'm always happy to see folks thinking about how to simply reduce waste.
