The Human Age

I have been reading Diane Ackerman’s The Human Age. As usual, I read good books several years after they come out.

The point of Diane Ackerman’s book is that humans have completely transformed the Earth to such an extent that no place is truly natural—nor is there, perhaps, any place that is entirely artificial. Humans have so completely transformed so much of the Earth that even the places we seemingly have not touched are now different, for example by global warming. But at the same time, all kinds of species have “invaded” the human landscape, whether transported by humans such as many invasive species (starlings from Europe, for example) or simply by exploring their way into our cities (as with coyotes downtown in cities).

Ackerman must be the world’s best science writer (in English, anyway). Try these quotes:

About urbanization: ...like splattered balls of mercury whose droplets have begun flowing back together, we’re finally merging into a handful of colossal, metal-clad spheres of civilization.

[The sun] reaches into the mumbling corners of our private universe, spurs growth, sheds light on all our episodes and exploits, transfigures daily life. Its edible rays feed the green plants on land and sea, which animals graze upon, and we dine upon in turn, and so it quivers through our blood. Every molecule of our being, every mote inside us, every atom and eave in the mansion of the body and the penumbra of the mind was forged in some early chaos of a sun.

And finally: Sometimes it seems as if Gaia were so pissed off she finally decided to erase her workmanship, atomizing the whole shebang and flicking our Blue Marble back into the mouth of the supernovas where our metals were first forged.

Years ago, someone who wrote a blurb for the jacket of my second book compared my writing to hers. Only now, upon reading Ackerman for the first time, do I realize what a compliment that was.

Much of Ackerman’s book is filled with small- or large-scale success stories of people who have capitalized upon the increasing desire among humans to reduce our impact on the Earth. She seems particularly impressed by natural buildings and vertical farming. All of this optimism is set against a background of terror, that humans are changing the Earth so much that we will no longer be able to fit our civilization into it, but she doesn’t talk about this very much. It is never very far, however, from the reader’s mind.

It was certainly never very far from my mind as I read the book. I was helping to supervise my ten-month-old granddaughter, who is exhaustingly cheerful. She loves exploring, or having attention paid to her, or being left alone to bang on things, and (we are lucky) she even likes most foods. She must have some incredible smile-muscles. And I kept thinking over and over about what kind of world she will encounter, a world messed up by earlier generations. It is not just my love for nature that makes me write and teach about environmental issues. I can always see her silhouette against our picture window with a view of flowers and leaves whenever I teach or write.
