Momoisapanda you're on the right track but you need to learn how to spell and look a little deeper. The song is criticizing more than just pollution. In general we (especially americans) consume in excess and waste so much. Also the lines "They'll be rich and dead, So let somebody else devise a cure for it." Isn't saying that we aren't able to find a cure and someone else might be able to stop it, it's saying that the people who are creating these garbage dumps that fill the air don't give a damn because by the time it has any effect on the world they'll be dead and gone so they'll let the future take care of the damage they do. There's a lot more to do with this song but I don't feel like explaining it. The rest is fairly, there isn't too much ambiguity.
