Gee, something new to fear, just when I had become somewhat adjusted to all the other tragedies befalling mankind. By the way, wouldn’t this cause a mini ice age, what with all the talk of Global Warming and all?
In contrast with the nonsensical “Global Warming” theory, which is far more religious-political than anything else, I’d describe this as a very real concern. You have a more or less unprescedented concentration of industry in a very small part of the world with very few controls spewing all sorts of noxious chemicals into the air.
Part of the problem is that:
1) The Boy Who Cried Wolf syndrome kicks in.
2) Nonsense about Global Warming distracts those inclined to worry about such things from actual problems.
