Don’t throw flourescent (or compact flourescent for that matter) bulbs in the garbage! They contain mercury which could enter the water supply and which is hazardous to human health. Earth 911 is a great site for finding out how to dispose of household hazardous waste. You just enter your zip code and it tells you about local facilities for safely disposing of old computers, cellular phones, NiCd batteries, flourescent bulbs and other household hazardous waste.
