I think you can put your mind at rest. One thing those people seem to fail to take into account is that humans are, by nature, VERY adaptable. It's why we're so successful. Even if all societies collapse, there'll still be people alive to rebuild.

If the crisis was a storm that we have to ride out, I might be able to agree with you. The problem is there are looming threats that we have no idea how severe they will be - like all the nuclear warheads that are still out there just waiting for someone to do something stupid. For some reason, since the end of the Cold War and the drawdown in the number of missiles the U.S. and Russia have pointed at each other, everyone has totally forgotten about the nuclear threat.
And when it comes to climate change - this is something that we could vaguely see coming on the horizon 30 years ago, but as more and more evidence has informed us of the degree and scope of danger, a well financed disinformation campaign by energy conglomerates has made it impossible to take any collective action to reduce carbon emissions.
As we move through this century and look forward to 450+ppm CO2 levels, the only thing in the past that we can compare the present with the past is the Paleocene Eocene Thermal Maximum of 55 million years ago. And even here we're in uncharted territory, because The rate of release of carbon into the atmosphere today is nearly 10 times as fast as during the Paleocene-Eocene Thermal Maximum (PETM), 55.9 million years ago. Some of the deniers today claim that the relatively low level of extinctions during the PETM mean we can just adapt to the changes we are causing now.
The first obvious problem is that adaptation will have to occur 10 times as fast as during the PETM, and there wasn't a huge human population on Earth 55 million years ago with cities, roads and other infrastructure, blocking the path for animal migrations to the north!
And what about us? We have almost 7 billion people on Earth today; are they all going to fit in Canada and Russia a hundred or two hundred years from now? My country will sure be alot more crowded!
What is especially alarming, is that after just assuming that global warming deniers were just rightwing ideologues afraid of international cooperation and a larger role for government, I pick up a book two years ago by foreign policy correspondent Gwyn Dyer "Climate Wars" and learn that most of the people he talked with at high levels of the Bush Administration were well aware of the threat, and expecting huge populations shifts or mass migrations, failed states, diminishing world-wide food production, and disease epidemics as a result of the impending changes that could start taking effect as little as ten years from now.
What I wished Dyer could have explored more was the motivations of these people at high levels of government and business. If they clearly see the problem, why are they okay with doing nothing about it? They are clearly taking the "adaptation" approach, but they know full well that there is not going to be enough food and resources for everyone, and everybody isn't going to fit into Canada 100 years from now, even when all the ice melts! To me, this means that assumption of the green movements - that we're all in this together, is not shared by the elites who rule the world. If they are young enough, they have personal plans for the future we are mostly unaware of; and in the longer term, they are making plans that their descendents are among the lucky few survivors, while most of the World's population, especially in the poorer nations in the Tropics become uninhabitable.
The environmental movements are motivated by a kind of universalism that only appears on the left wing of the political spectrum. While the various right wing groups are following the usual selfish strategy of me-first lifeboat ethics. Maybe all this is why I'm bucking the usual trend, and becoming more radical as I get older. A cooperative approach at least has a chance of ensuring future survival, while the rightwingers may find their "life boat" tipped over by desperate millions fighting to be among the survivors.
It's also interesting how religion can be used to support both universal and selfish strategies. Once again, religion could be a force for good, or a justification for genocide. It also doesn't help the majority if it feeds a complacent attitude that God will just come down and fix everything.
Damn! I had to remove my links...something about a 15 post threshold.
