^ Towards the last few posts in this thread.....
A long bit ago, there was an article in
Runner's World about a man whose passion was statistics and who kept records for many top-seeded runners. Before he retired, he was a professional weatherman, and as a part of his personal and professional interest had charted a number of climate/environmental trends, and was of the opinion that we were indeed headed for an extinction-level event in term of Global Warming. Despite being a "Hippy Environmentalist" himself, however, he said that by looking at the data objectively, he had seen that the Earth was simply on a warming trend just as it went through the Ice Age so many years ago, and that while what we're doing to it has possibly led to some acceleration of that eventuality, it was nevertheless always a natural eventuality: that it was just a part of the Earth's natural cycle.
I personally do believe in Global Warming and how climate change has influenced today's more violent weather swings (or even if that change is another Ice Age as somehow the deep ocean currents manage to reverse, much as was popularized in the disaster movie "The Day After Tomorrow").
Similar to this man, I do not, however, believe that it is our doing as industrialized humans -be it from use of fossil fuels or overpopulation- that have brought-on this change. Nor do I particularly see the significance of our contribution to it, based on these factors.
Much as we left our parents homes as we grew to be adults, I believe that we as a species must also leave Earth if only to ourselves from the very real attempts that Mother Nature has made to kick us out of her basement. Either we get out, or She'll smother us.
For whatever reasons, we've given up looking up at the stars. I think that we are tremendously short-sighted as a species -as we typically are- and are seeking to save something that we simply cannot, because Mother Nature is both much greater than us and also cares not. I'd actually rather we expend our resources now in an effort to improve our lot, rather than to stay stagnant. Even if we stopped all our harms to the planet now, how many more generations will that afford us? Let's figure out a way to leave this place before we are ultimately killed by climate change, disease, or any of a host of other possible natural causes as the planet tries to rid herself of our burdens.
We can then look on from our new homes as the years pass and the Earth again renews herself, to be ready again for us to come back and call it home.
.....ok, I've ranted a bit. Sorry.
