A scene from “Unfinished Business”

The next golden age of human achievement begins here and now: New Year's Day of the next cosmic year. In the first tenth of a second, we take the vision of the Pale Blue Dot to heart, and learn how to share this tiny world with each other . . . as the effects of climate change reverse and diminish. A fifth of a second into this future people will stop dying from the effects of poverty. The planet is now a completely self-sustaining, intercommunicating organism.
