"In 2016, during an interview with Larry King of the Larry King Now talk show, Hawking said that humankind has always been its own greatest problem. We are consciously careening too close to a time when climate change would be irreversible, and sadly, there is no breakthrough in sight.
"In another interview with BBC, Hawking said, “We are close to the tipping point where global warming becomes irreversible. Trump’s action could push the Earth over the brink, to become like Venus, with a temperature of two hundred and fifty degrees, and raining sulphuric acid.”…
"While there may still be a chance to save the earth, Hawking was convinced that humankind would never see reasons to take solid, united and well-targeted actions. In his words, “[…]evolution has inbuilt greed and aggression to the human genome. There is no sign of conflict lessening, and the development of militarized technology and weapons of mass destruction could make that disastrous.”
"The only way to preserve our species would be to secure some sort of backup planet for a time when the earth would become completely inhabitable."
Or send baby Superman in a space ship to the planet Krypton.
Americans have selected Greed and Stupidity by electing President Trump.
