No, I am being quite serious. What exactly justifies your existance on planet earth? You still consume resources on this planet and ulimately; your existance will be a net negative carbon footprint.
My solution to this? Mass suicide! Have every vegatarian and vegan kill themseleves, preferably somewhere where their bodies could de-compose and feed the soil like fertilizer to raise awareness of the tradegy...
Along with the usual things (composting, new bulbs, walking, reusing bottles, etc.), I'm an environmental science major at my college. Education and awareness play a big role in helping people understand how the world around us works and how our actions impact the environment.
I take a moment to remind myself that carbon is one of the basic components of all life on this planet, and isn't a bad thing - at all.
Then I remind myself not to use the "swirly" mercury filled bulbs, because they're far worse for the environment than regular bulbs.
The packaging even says if you break one, evacuate the room for 15-20 minutes, open a window, and be very careful not to get any of the contents on your skin.
After these build up in dumps for a few years... you think it'll be BETTER for the Earth?
