There is a safe way to recycle asbestos btw. It gets sintered and by this process disarmed forever, it turns into a block of glass. It’s expensive though so it gets put into plastic bags and then bulldozed (in this process the bags rip) and covered in landfill, where it can wash out and contaminate fully unfettered.

Pedantically speaking, land filled with asbestos isn’t so unusual—it’s mined out of the land.
