For the next few weeks, the buzzword in US debates on the liberal/left about economics and ecology will be “abundance” after the release of the book with that title by Ezra Klein (New York Times) and Derek Thompson (The Atlantic magazine).

The book poses politically relevant questions: Have policies favored by Democrats and others on the political left impeded innovation with unnecessary red tape for building projects? Can regulatory reform and revitalized public investment bring technological progress that can solve problems in housing, infrastructure, energy, and agriculture? The book says yes to both.

Those debates have short-term political implications but are largely irrelevant to the human future. The challenge is not how to do more but how to live with less.

All societies face multiple cascading ecological crises—emphasis on the plural. There are many crises, not just climate change, and no matter what a particular society’s contribution to the crises there is nowhere to hide. The cascading changes will come in ways we can prepare for but can’t predict, and it’s likely the consequences will be much more dire than we imagine.

If that seems depressing, I’m sorry. Keep reading anyway.

Rapid climate disruption is the most pressing concern but not the only existential threat. Soil erosion and degradation undermine our capacity to feed ourselves. Chemical contamination of our bodies and ecosystems undermines the possibility of a stable long-term human presence. Species extinction and loss of biodiversity will have potentially catastrophic effects on the ecosystems on which our lives depend.

Why aren’t more people advocating limits? Because limits are hard.

I could go on, but anyone who wants to know about these crises can easily find this information in both popular media and the research literature. For starters, I recommend the work of William Rees, an ecologist who co-created the ecological footprint concept and knows how to write for ordinary people.

The foundational problem is overshoot: There are too many people consuming too much in the aggregate. The distribution of the world’s wealth is not equal or equitable, of course, but the overall program for human survival is clear: fewer and less. If there is to be a decent human future—perhaps if there is to be any human future—it will be fewer people consuming less energy and creating less stuff.

Check the policy statements of all major political players, including self-described progressives and radicals, and it’s hard to find mention of the need to impose limits on ourselves. Instead, you will find delusions and diversions.

The delusions come mainly from the right, where climate-change denialism is still common. The more sophisticated conservatives don’t directly challenge the overwhelming consensus of researchers but instead sow seeds of doubt, as if there is legitimate controversy. That makes it easier to preach the “drill, baby, drill” line of expanding fossil fuel production, no matter what the ecological costs, instead of facing limits.

The diversions come mainly from the left, where people take climate change seriously but........
