>The potential solutions that come to mind range from, on the pessimistic end, apocalyptic, to technological if we are to be optimistic. We'll either think our way out of the crisis with cleaner sources of energy, or nature will have it's way and our population will dwindle.
That was the original statement. To me, the fact that 'range' is included, means there's more than just two choices implied. I do believe it misrepresents the argument to suggest that there's only two 'extremes' of "taxes and regulation" or else "we go extinct."
