This week, Erin talked about how she's helping her parents (and learning from them) as they maintain an outdoor compost pile. By composting, you can nourish your garden for very little cost while keeping organic garbage out of sewer systems and city dumps. Compost materials range from food scraps to worms, and you can keep your compost in an open pile outdoors or in a specialized container.

Of course, composting isn't just for homes - you can also participate in composting at the office.

Whether at work or at home, indoors or outdoors, worms or food scraps: Have you ever tried composting? Why or why not?
