"For Musk, going to Mars is way more than just cool. "Are we on a path to becoming a multiplanet species or not?" he has asked. "If we're not, well, that's not a very bright future. We'll simply be hanging out on Earth until some eventual calamity claims us." Impey makes much the same point. "Humankind evolved over millions of years," he observes. "But over the last 60 years, atomic weaponry created the potential to extinguish ourselves. Sooner or later we must expand beyond this blue and green ball, or go extinct." So does Petranek. "There are real threats to the continuation of the human race on Earth, including our failure to save the home planet from ecological destruction and the possibility of nuclear war," he writes. "The first humans who emigrate to Mars are our best hope for the survival of our species.""
