I’m not sure why this post is appearing now (it refers to Earth Day, which was in April, and the 40th anniversary of Earth Day, which was last year), but the suggestions are still good–even if #5 and #36 are the same thing.
For the record, we’ve done about 3/4 of these. I think the one I feel best about is #13: Stop using paper plates. We have a lot of cookouts in the summer, and it quickly became obvious that paper plates were going to make up too much of our trash if we allowed them to. So we didn’t. We bought cheap reusable plates at IKEA and Target, and now we can host about 15 people without throwing away a single plate.
