When people talk about the Earth's temperature, they always bring the lamest things into the argument as to what is causing it, but always leave out the fact that the Earth is getting closer to the Sun in one point...hotter temperatures, and farther at another...colder temperatures, as time goes on. And since our axis around the sun isn't perfect, coupled with the Sun's own climate storms, you gets fluctuations in space that alters our climate. Sure, scientifically speaking, driving cars, producing more babies, killing trees all produce or inhibit the degradation of Co2, which can *eventually* cause a temperature spike, but the thing is that Earth's temperature has been rapidly rising before humans ever were a problem on Earth...(polluting it).
I specifically stray away from talks about this hot topic called "Global Warming" when the speakers/talkers are at a conflict of interest...i.e. PROFITING from it.
Use your own brains people. If you believe something is doing harm, fix your problem, don't try to change everyone's mind about it!
