Shielding a Flickering Flame

With the folly of the human race—and perhaps its unconscious lust for self-annihilation—on display at the U.N. Climate Talks in Warsaw, it is easy to succumb to despair. The world’s elite, it is painfully clear, will do little to halt the accelerating destruction of the ecosystem and eventually the human species. We have, through our ingenuity and hubris, unleashed the next great mass extinction on the planet. And I suspect the reason we have never discovered signs of intelligent life elsewhere in the universe is because extraterrestrial societies that achieved similar levels of technological development also destroyed themselves. There are probably more wreckages of advanced civilizations, cursed by poisoned ecosystems, floating through the universe than we imagine.
