When I hear people tell me that humans are the reason that the Earth is dying, for some reason it makes me think of Gaia from Captain Planet. I look back on that show now and ask those people that tell me these things if they liked the show and they yell it's better the anything in the world. Tells it like it is.
I can't believe I dogged a bullet, I used to like it, but then given how young I was, I'm surprised and scared of what could have become.
I'm so sick of self-loathing treehuggers bitching about how the world would be better off without humans. Without humans, you have a bunch of ignorant animals and plants that aren't intelligent enough to appreciate the Earth. Without humanity, it all means nothing.
PS, after reading some of the comments here: Maybe you should do a cartoon about how liberals demand documented facts to back the points of conservative arguments, but liberals never feel the need to actually provide any, themselves. Or how liberals expect YOU to do their research FOR them when they want to know something. Or how even when you DO provide this documentation, they immediately jump to 'you can't prove they aren't biased!' but ignore the fact that all of their OWN sources have the same potential for bias.
