I share something of which I was reminded after the hilarity in the podcast comments.
If you haven't heard it yet, the late (and great) George Carlin once explained the most obvious reasoning to not wanting to wreck the planet with our industrial death smokes and the like. It's far simpler than "is our pollution causing the death of the world?" Far, far simpler . . .
Language warning. It's George Carlin. You know this.
I'd miss the whales, though . . . also, hilarious sidenote: according to Assassin's Creed: Brotherhood, British Petrol is totally in line with the Templars. Explains a lot.
