If you have stuff that you need to get rid of but don't have time to donate or have a yard sale, don't just chuck it. Check out Freecycle.org which will direct you to local freecycling groups. It's a great way to reduce land fill and put your stuff to good use for someone else. It's also a good way to find free stuff.
Recycling isn't just for bottles and cans anymore. Check with your local recycling company to see what you can include. In many places you can recycle broken down boxes, junk mail, magazines, and more. Think carefully about your trash, and recycle everything you can.
