The Last Word On Nothing

Evolution, we are often reminded, conducts itself at a glacial pace. It throws its dice and picks its favorites over thousands of generations—plenty of time, we wearily explain, for a functional eye to develop. By the same slow token, this process, life’s old standby for adapting to new environments, will not be fast enough for most to transform themselves and avoid getting trampled by the oncoming stampede of anthropogenic climate change.

Only that’s not strictly true. Most on this earth are not, in fact, slow evolvers. Given enough food, a generation for many might mean only half an hour or so. Bacteria and other contagious pathogens most certainly will adapt in response not only to climate change but to the species loss that precedes and accompanies it.

There’s a principle known as dilution theory that links species loss with increased infection. It’s very likely that in pushing our fellow beings off the extinction cliff we put targets on our own backs in ways we don’t fully understand.  Continue reading →

On Tuesday, I texted my friend Michelle a brief video clip of a polar bear.

The bear is starving, all jutting hips and elbows, its fur sparse except for a thatch along its spine and Clydesdale tufts around its plate-sized paws.

Dips its face into a rusty barrel and pulls out what appears to be a hunk of rotten meat. Sprawls on the ground, nose to earth, defeated by the visibly difficult work of breathing.

Watching the bear, I covered my mouth with one hand, suppressing tears. This perfect summary of unchecked climate change was like a knife to the kidney. Without sea ice, polar bears can’t hunt seals. And we are to blame.

“I honestly don’t think I can watch that,” Michelle replied. “I can’t get down with the voyeurism of photography generally.”

Michelle—an artist who’s been thinking a lot about polar bears and the Arctic these days—does not shy from engaging tough topics. What bothered Michelle was the lack of direct agency. The doing nothing in the face of such obvious suffering and then using the suffering to convey a message. Some key step had been skipped. More…
