Well even if she can't dance, she can still come along.
I wouldn't say so much pollution? It's something to do with air pressure and...the stratosphere and other science-y thing. Just climate, really. Precipitation happens and everyone freaks out, but after being in actual rain storms? So not rain, more like drizzle.
Instead, we get earthquakes and fires. Like, because it's so dry, there's fodder, but then after the random rainy seasons that aren't really rain like here, then you get more growth, which leads to more fuel for the fires when it's dry again.
