Now your just making baseless statements. There is no proof that it will kill anybody. Besides the economy will bounce back if nature and the environment aren’t that severely hit.
And since man made climate change is real according to the vast majority of the worlds scientist (everyone of them who is not in the pocket of the fossil fuel lobby) it is damn likely we would preserve our planet for future generations. Of course some frustrated redneck hiding behind the confederate rag wouldn’t agree with the most renowned scientists of the world. I am not surprised there.
