What Trump can't fathom, and neither can his henchmen, is that pollution does not stop a border.  Maybe he'd build a wall in the lakes?  Sound stupid?  No more than his Mexican one.  Canadian and American cities around the lakes suffer from past pollution and great improvement has been made.  Wait until the next cuts are proposed?  I suppose Trump thinks acid rain stops at the border as well.  Concur that the P.M. has to get tough with this renegade in the White House.
