The Earth is going downhill and humans' best chance for survival is to evacuate, as far as Elon Musk is concerned. In a Wednesday interview at AllThingsD's 2013 conference, the Tesla Motors CEO explained why he's so into colonizing Mars. "Either we spread Earth to other planets, or we risk going extinct," he said. "An extinction event is inevitable and we’re increasingly doing ourselves in."
