Nate, we are pretty close to agreement.  While some might believe in human extinction, I don't.  What I mean by collapse and dieoff is the the world will become a lot like Rapa Nui (aka Easter Island) after the last tree was cut.  Rapa Nui continued to be habitable post collapse, just with a smaller and poorer population.

Of note, Niue and the Cook Islands have only avoided collapse by exporting their excess population growth to New Zealand and importing food.  If the planes and boats stopped coming, they would have to revert to the old method of sustainability - warfare.

As long as someone is allowed to make money mining tar sands or destroying rainforests to grow biofuels, it will continue.  I just can't see nature lovers ever outnumbering auto lovers or becoming more powerful.

Of course, just by being alive I am part of the problem.  How else could it be?  I am a self serving yeast just as is Jay Hanson, James Lovelock, Al Gore, and David Suzuki, none of them has committed suicide either.  The only non yeasty thing I ever did was decide not to have children.  Beyond that, I am following the AMPOD path of not trying to save the world, but just trying to use the mechanisms of our society to build a lifeboat for extended family and friends so I can finish my days as a (relatively) comfortable yeast while the world continues to burn up.
