Humanity is a flawed creation. Humanity never asks itself why it deserves to survive. Maybe we don't...
Now, BSG quotes aside... There is inertia to humanity. We may be more aware of environmental issues than we were a few decades ago, but do the majority of people ultimately care...? We tend to have short-sighted views, but that comes from the fact that, ultimately, we're human. Call it natural instinct, the "id", what-have-you, we're human and primarily concerned with what affects our condition minute-by-minute. Sure, you can see about 'informing' people, 'educating' them... but until the majority give a damn, change will not happen. Sure, you can see about forcing people to change, but theoretically that goes against ideas like freedom, rights, etc., ideas that people who are 'environmentally conscious' often claim to also espouse.
I see what is around me, I do what I can. But humanity rumbles on, and will continue to do so. I might affect a portion, but the whole? Not a chance.
In general, I believe in humanity. We're survivors, tenacious bastards at best and worst. It might take the proverbial cosmic/global/whatever "clue bat" to get us to change our ways, but humanity will take our hits, and survive. And if we don't? Ah well, "C'est la vie." If we can't claw our way out of our own messes, perhaps no, we don't have the right to survive.
'Course, I still think we're shooting ourselves in the foot by not getting off this rock, but hey, that's a discussion for another time...
But for now, BRING ON THE HEALTHY WIMMINS. Have a refreshing beverage, recycle the goddamn container if you like, and enjoy the moment. After all, that's pretty much what humanity is about. Voluptuous, Rubenesque, buxom, it's all good to me and I shall fap to my heart's content if I so desire. Carpe diem..
