There will likely be a time when Trump's children or grandchildren will regret his cavalier, money-oriented approach to issues like the environment, including the appointment of this guy to head the EPA. This is a very intentional poke in the eye if there ever was one. 

It would be good if Trump's children and grandchildren would live in Miami Beach and watch streets that never used to be washed over by sea water become progressively more often covered at high tide. OTOH, maybe that will also happen to lower Manhattan, which they might occasionally visit when they get out of their "Tower". 

Unfortunately, they probably won't care either. I hope I am wrong about that, but I don't think so.
