I'll try to be as, er, sensible as I can be in regards to this topic. In the grand scheme of things, Humanity is about as meaningful as an Amoeba... which is to say utterly meaningless and, at the same time, of the utmost importance. If a single Amoeba or the entire Human Race were wiped out, life would go on and there would be no one or nothing that would give a crap.
Yet, at the same time, both the Amoeba and the entire Human Race are absolute trimphs of physics and chemistry. Any life, all life, is such a rare and beautiful thing because most of the shit out there is just dead rock and empty space. And Hydrogen. Lots o' that shit too.
People who say humanity is the "monster" are wrong simply because we're no different than any other living species with power. We fight, fuck, and eat way too much and will, eventually, eat and fuck our way into our own natural culling as starvation and disease ravage Humanity and bring our population levels back down into a sensible level. We might be able to prolong the agony with science, but the existence of superbacteria like MRSA and whatnot say to me that it won't work for too long.
No matter how much a single Ameoba or the Human Race tries, all things eventually flow back into equilibrium. Also, in the end, it doesn't matter how much damage we do to this planet, 'cause once were gone (either into space or six feet deep) it'll repair itself and start the whole crazy process over again.
So, you ask if we should be exempt from culling? No, because culling Humanity is meaningful only to Humanity, just as culling Deer is only really meaningful to Deer. But a line should be drawn between culling and extinction. I think the Human Race could use a decent predator... it'd certainly make our continued evolution interesting. There is absolutely nothing about humanity that is no better or no worse than any other living creature on the planet. We all do the exact same things, commit the same sins: we all murder, rape, commit incest, go to war, and live life like our species is the only species worth a damn. More hippy types seem to think Humanity is alone in the world regarding this... and to this I say they need to pay more attention to how nature actually works.
All life is special, all life is sacred, and sometimes living means other things need to die. That is nature. We're not apart from that (yet) in any way, shape, or form. What's good for the goose is good for the gander, I say.
But that's just my opinion, I could be wrong. Or just crazy.
