Change your light
If every household in the United States replaced one regular light bulb with a compact fluorescent bulb or LED light, The pollution reduction would be equivalent to removing one million cars from the road. If the color of fluorescent bulbs bothers you then you can just replace the bulbs in less frequently visited areas such as closets and laundry rooms. Every little change helps the environment at least a little bit so go out there and make these new  and better lights known!!
