such changes had happened gradually enough to seem salubrious

Now we know what we’ve done. Or we should. The fuel-burning binge (and the beef-eating binge, and the forest-clearing binge) we’ve been on for the past 150 years, and especially the last 60, and increasingly and accelerantly, has brought into view the most dangerous threat in the brief history of our civilization. It’s become possible to glimpse the disappearance of so many things, not just glaciers and species but ideas and institutions too. Things may never be so easy or orderly again. Our way of life that used to seem so durable takes on a sad, valedictory aspect, the way life does for any 19th-century protagonist on his way to a duel that began as a petty misunderstanding. The sunrise looks like fire, the flowers bloom, the morning air dances against his cheeks. It’s so incongruous, so unfair! He’s healthy, he’s young, he’s alive—but he’s passing from the world. And so are we, healthy and alive—but our world is passing from us.

I opened a window—not a real actual window, rather an otherness or alterity—a sill for my filth.

If such a thing as a literary/political/intellectual left exists, it is defined by its capacity for imaginative and sympathetic reach—by its willingness to surmount barriers of difference (class, distance, nationality) and agitate for a more equitable distribution of the goods and goodnesses that make up our idea of human (and nonhuman) well-being. To be able to imagine what it might be like to be tortured, or to live in abject poverty, or under the watchful eyes of US Predator drones—this capacity is crucial to the project of any political left in a wealthy country. But in the case of global warming, our collective imagination has failed us utterly.

The most powerful and cogent critique that can currently be leveled against our mode of capitalism is that markets fail to account for ecological costs. In a crowded world of finite size, our political economy values only acceleration and expansion. Scarce natural resources like clean air and water, not to mention more complex systems like rainforests or coral reefs, are either held at nothing or seriously undervalued. Corporations could clear-cut all our forests, reduce croplands to swirling dust, turn rivers to conveyors of toxic sludge, deplete supplies of minerals and metals, double and redouble carbon emissions—and all our economic indicators would show nothing but robust growth until the very moment the pyramid scheme collapsed. Indeed, most of these things are happening, with only scattered opposition. When our math improves, when the costs of our products fully reflect the resources used and the wastes produced—especially CO2: then and only then can capitalism begin to become a viable and humane economic system.
