We need to send into space a flurry of artists and naturalists, photographers and painters, who will turn the mirror upon ourselves and show us Earth as a single planet, a single organism that’s buoyant, fragile, blooming, buzzing, full of spectacles, full of fascinating human beings, something to cherish. Learning our full address may not end all wars, but it will enrich our sense of wonder and pride.

We think of apocalypse as a moment — a flash of light, then you’re gone — but if we study the earth’s history, we find that it’s not one moment. It’s actually a long process. In fact, it’s hard to see where it begins or ends. Like right now: evidence indicates that we’re experiencing the planet’s sixth mass extinction — a period when the rate of extinction spikes and the diversity and abundance of life decrease. Each such extinction event takes hundreds of thousands of years to play out, and it’s generally 5 to 8 million years before the previous levels of biodiversity return. So are we at the end or the beginning of a cycle? This could just be a temporary spike. The pattern could swerve in a different direction.

I prefer to ask what gifts the land offers. Gifts require a giver, a being with agency. Gifts invite reciprocity. Gifts help form relationships. Scientists aren’t comfortable with the word gifts, so we get ecosystem services instead. These terms arise from different worldviews, but both recognize the way the land sustains life.

I stayed two days close to the bodies of the giants, and there were no trippers, no chattering troupes with cameras. There’s a cathedral hush here. Perhaps the thick soft bark absorbs sound and creates a silence. The trees rise straight up to zenith; there is no horizon.

Nearly 50 percent of the habitats where I’ve made recordings over the past forty-plus years have been so severely damaged that they’re now either biophonically silent or altered to the point of being unrecognizable.

The pathless world of wild nature is a surpassing school and those who have lived through her can be tough and funny teachers.

Researchers find in their polls that the attitudes of the poorest 70 percent of Americans have essentially no effect on policy. Those people are disenfranchised. It doesn’t matter what they think. Political leaders just don’t pay any attention to them. As you move up the income scale, you see a little more influence. By the time you get to the top, attitudes and public policy are very similar, because the few at the top are the ones who design the policy. They essentially get what they want. You can’t call that democracy. It’s some kind of plutocracy.
