A canard is a lie. The Cuyahoga River caught fire, for the 15th time, in the summer of 1969.
Too bad your infatuation with industry and Trump causes you to rewrite history.
There were very few national environmental regulations in 1969. Very few bothersome burdens.
That's what Trump wants, right? No bothersome regulations. Of course, business considers all regulations to be bothersome.
Businesses thrived in the 1960s. The environment didn't.
