Science fiction writer and ecologist Kim Stanley Robinson (previously) writes that we need to "empty half the Earth of its humans" to save the planet — but not by the Green Left's usual (and potentially genocidal) tactic of reducing our population by 50%.

"The Hard Problem" is a new episode of the Into The Impossible podcast from the Arthur C. Clarke Center for Human Imagination: it features the outcome of a collaboration between legendary performance artist Marina Abramović (previously) and environmentalist science fiction writer Kim Stanley Robinson (previously): a short story about an interstellar journey incorporating elements of Robinson's outstanding 2015 novel Aurora -- a novel that is pitiless in its insistence on rigor in our thinking about the problems of living in space and on other planets.
