Fuller context:

Before long, for all of them, a desire takes hold. It's the desire - no, the need (fuelled by fervour) - to protect this huge yet tiny earth. This thing of such miraculous and bizarre loveliness. This thing that is, given the poor choice of alternatives, so unmistakably home. An unbounded place, a suspended jewel so shockingly bright. Can humans not find peace with one another? With the earth? It's not a fond wish but a fretful demand. Can we not stop tyrannising and destroying and ransacking and squandering this one thing on which our lives depend? Yet they hear the news and they've lived their lives and their hope does not make them naive. So what do they do? What action to take? And what use are words? They're humans with a godly view and that's the blessing and also the curse.
