We’ll call it planet B. Planet B is a place of natural beauty — unspoiled by pollution, unmonitored by satellites, untouched by the hand of human endeavour. Now imagine that, at some point in the future, our descendants discover planet B and its colonisation commences.. Given this unprecedented new opportunity, what could we do better? If we can imagine a planet B that is sustainable and inclusive, what does that mean for our world, and our future here on planet Earth?
