Mike Pence seems to be a nutter as well.
He refers to the statement that a species’s eating habits have an effect on its environment (he was talking about human beings who live in the US) as if it were a weird, wacky belief that any sane person would realise is false.
Perhaps he started off crazy. Perhaps working with Trump for four years sent him that way.
It’s hard to avoid laughing at a man in such an important position making such a fool of himself, basically denying an obvious fact about life on Earth that you would have thought everyone would know, but really we shouldn’t laugh.
