We need to save the Arctic not because of the polar bears, and not because it is the most beautiful place in the world, but because our very survival depends upon it.
Laboratory experiments, field observations and atmospheric modeling calculations have now established that chemical reactions occurring on PSC particles play a central role in polar ozone depletion.
The products built in the factories of G.M., Ford and Chrysler are some of the greatest weapons of mass destruction responsible for global warming and the melting of our polar icecaps.
Polar bears did very well in the warmer times. They didn't die out at all; they didn't die out in the last 10,000 years, nor during the previous interglacial, nor the one before that. So, they're just used as a deceitful heartthrob; you know, to pluck your heartstrings because the polar bears might die out.
As a rule, anything that is pretty you avoid when on an expedition in the polar extremes. Normally anything other than white means a hazard such as a crevasse.
