What's the problem?
Pillock,
Step back a few million years....we had the ice age when the earth was supposedly destroyed and all the dinasours etc etc etc became extinct.... this is evolution!
So the polar caps melt and we all drown (not that you and I will ever see it)....regardless of the cause, that too is evolution!
I say LET IT EVOLVE! It is just nature taking its course. No number of Bob Browns are going to stop it happening today, tomorrow or ever.
Just a question though, and answer honestly, what type of car do you drive? If you were genuinely serious about what you preach, the answer should be NONE!
