As a very little kid, I thought clouds came from the chimneys of factories. Not an entirely unlogical conclusion, I think. It’s probably because for a couple of years, when I was still in kindergarten, we used to live in a little valley with a huge paper factory. The river downstream used to be colored in weird colors, like pink, depending on what color toilet paper they used to make at the point. As a kid I thought that was really funny! But now I’m glad that we have stricter environmental protection rules!
Oh, and talking about smoking chimneys… Is anybody else annoyed, whenever there’s a tv news or documentary piece on pollution or the evil CO2, that they show smoke stacks emitting water vapor on an obviously cold day? I mean there is enough crap and pollutants being emitted, why not show the really nasty stuff?
