Actor Alec Baldwin thinks anyone who doubts the theory of global warming suffers from a form of mental illness.
The actor spoke to AFP from the United Nations about the Paris Treaty.
“There can be no successful climate agreement and no future for our planet without greater protection of the world’s forests, everyone in the room understands this,” Baldwin said in his appearance at the U.N.
"And so much of what's coming on now is something that we have to treat as some kind of mental illness," he said. "I believe the climate change denial is a form of mental illness."
