It wasn't bad enough when Trump pulled this country out of the Paris Accords. He then directed his EPA to nullify all of Obama's clean air initiatives. Now he is reversing the rules that makes cars improve their mileage and emissions. He seems determined to do his part to destroy our environment. He is either incredibly stupid (a definite possibility), or believes that short-term corporate profits is more important than leaving a livable planet for our descendants (a probability).
Whatever his reason, he is out-of-touch with the wishes of the American public. About 66% (two-thirds) of the public believes global climate change (global warming) is real, 55% believes the scientists when they say it is caused by human activity, and 56% believe it has already harmed this country. Only one group disagrees -- Republicans (who have shown they will follow Trump no matter what he does)>
