“This past year - if you'd have tried, you'd have seen even more clearly the futility of trying to change the world without the efforts of everybody else on Earth. You saw and smelled and drank the evidence of six billion disasters that can only be mended by six billion people. || A thousands years ago this wouldn't have been the case. If human beings had suddenly vanished a thousand years ago, the planet would have healed overnight with no damage. Maybe a few lumps where the pyramids sand. One hundred years ago - or even fifty years ago - the world would have healed itself just fine in the absence of people. But not now. We crossed the line. the only thing that can keep the planet turning smoothly now is human free will forged into effort. Nothing else. That's why the world has seemed so large in the past few years, and time so screwy. It's because Earth is now totally ours.”
