Orion asked thirty writers and thinkers to name one thing we will increasingly need over the next thirty years if humans are going to find a way to live happily, sustainably, redeemably on earth. Here is the result. From “optimism” to “improvisation,” from “young farmers” to “empty pockets,” the responses collected here are as wide-ranging as they are compelling. Imbued with thoughtfulness and buoyed by a profound sense of justice, this thin volume makes an eloquent statement about the future of humanity.
