other planets have no biosphere, entirely different atmospheres, entirely different compositions and no fucking people running around. There are no people on those planets studying them 24/7 and none on earth who all got together in a giant fucking moneygrabbing conspiracy to fake the totally unreasonable conclusion that a species changing, refining and wasting the elements of the earth is going to have some discernible effects on the planet after a while. I know it's a fucking crazy idea isn't it? Really a lot to grasp, I know but I think it would stand to reason that resources are both finite and can be misalocated into other forms and parts of the biosphere that can cause damage to the species.
Smarten the fuck up, does that sound like a massive global conspiracy or common fucking sense?
