I don't know about the vegetarian thing. I love my chicken. I don't think I could live without it, but blackle.com seems like a good idea. I never even knew about it.
Anyways, everyone could do a little something to help the environment, such as:
-Unplugging chargers when not in use
-Conserving energy by turning off lights when you aren't in the room
-Taking shorter showers to conserve water
-Using energy-conserving light bulbs
-Using low-flow toilets and shower heads
-Washing clothes in warm water instead of hot water
-And obviously, recycle
