Seriously this: smoke stacks are a carefully engineered structure specially to ensure air emissions diffuse and don't roll along the ground.

You absolutely cannot park a bunch of truck mounted generators next to an existing plant and go "yeah it won't make a difference".

Once, when I was a child, I remember the carefully engineered smoke stacks in Sudbury Ontario spilling out acrid smoke sideways, and then straight down into the town.

Back then, Sudbury looked like Mars.

So you're saying when not done properly, emissions have very direct negative impact on the surrounding community. Did I get that right?

No theyre saying that since that day everyone has given up and nothing matters anymore. We all collectively decided that it is OKAY and didnt change a single thing since.
