    Acidic rain.

    I don’t remember any of the specifics anymore but it boils down to: Trees and plants died in masses, scientists and the general population got together and we changed what caused it.

      I work for a company that, among other things, helps monitor NOx and SOx emissions at power plants and other polluting facilities. Trust me, this is still something we’re still very worried about and barely keeping a handle on

        Really? I thought it was mostly solved by regulations that require filters at the industrial sites (and aren’t those used in Diesel cars, too?).
