What does Al Gore have to do with planetary peace?

I need to applaud Georgie Anne Geyer for her wonderful piece on the link between Al Gore and the Nobel Peace Prize.

Some key quotes:

But the funny thing is that the critics of the Gore award have it all wrong. In fact, the deeper one digs into the historic reasons for chaos and collapse of societies across the globe, the more one finds that the real reasons behind many of the endless wars were precisely environmental degradation and collapse. Ironically, the turmoil in Iraq has its roots in the environmental problems of ancient times.

...supposedly ingrained "ethnic" wars like those of Rwanda and Bosnia came about not from old hatreds so much as rivalry over the environment that alone can sustain those human populations.
