Wow, is this a serious post? The oldest, richest living culture?
A culture characterised by tribal warfare and brutalisation, which didn't even invent the wheel? I could name about, oh a hundred "richer" cultures.
Yes, human history, like the history of any species, is littered with barbarities. Human history is rich with good and bad, that's part of the rich tapestry that is human existence. You might have a culturally absolutist view of the world but in reality humans evolve and adapt to their circumstances, say what you like about indigenous cultures, at least they knew how to live sustainably on their land and didn't invent such wonderful cultural constructs such as industrial-scale warfare and nuclear arsenals. And you're kidding yourself if you think our culture isn't charcterised by tribal warfare and brutalisation. The only difference is that we developed technologies to do it on a far, far great scale. Just ask the 100,000 odd Iraqi's we killed in this decade alone what they think about our superior culture.
We are a strip mining culture? Yes, we have mines but to describe this as our "culture" is rubbish.
You'd probably be well served by reading the book in question. We strip mine ALL of our resources, from minerals right down to agriculture. Our "bread basket", the Murray Darling is already on the verge of collapse, and we strip mined the agricultural potential of our top-soil a long time ago, so much so that we no longer grow staple crops in top soil, the land is little more than a substrate into which we pour energy intensive fertilisers in order to get anything to grow at all. We strip mine our forests, our soil, our minerals, our fishing grounds etc etc etc. And this land is very, very poor in terms of geological renewal. It is an old, tired land, that simply won't sustain this sort of degradation for much longer. There is a very good reason that Aboriginals never invented the wheel, the land can't sustain high populations that require the sort of societal organisation that leads to such technological developments
Finally, what is wrong with relying on our connections with the rest of the world? And please give us an estimate of our demise in the not too distant future.
Soooo much wrong with this post.
Nothing is wrong with it, per se, but it is not sustainable, and once the environment gives us the old heave-ho then all the connections in the world won't save us.
As for time scale, I don't know, maybe it will be a century or two into the future, maybe it will be sooner. But remember, there is ample evidence of societies that existed longer than we have who were permanently wiped from the pages of history once their environments could no longer sustain them. I'd look into the histories of Greenland and Easter Island if you want some historical parallels.
