Using science, technology, and cheap energy, we expanded farmlands, chain-sawed forests, exploited fisheries, mined minerals, pumped oil, and flatten… - Richard Heinberg

For a population of field mice in overshoot, the critical resource might consist of small plants whose unusually robust growth has been triggered by high levels of rainfall. For humanity currently, the critical resource is fossil energy. Temporary energy abundance has led to many good things (for some of us, anyway): more food, more people, more commercial products, more knowledge, more comfort, and more convenience. But we are about to become victims of our own success.

We’ve spent the last few million years evolving big brains, and we won’t un-evolve them in short order. Further, encouraging dull-wittedness and ignorance would result in terrible short-term consequences (as we Americans are likely to discover during the second Trump presidency). Moreover, intelligence is cool: it gives us art, music, literature, science, mathematics, and so much more. At least some of these achievements and abilities are arguably worth saving. So, what’s our best long-term plan to avert self-destruction, given that intelligence is now baked into our species?
There are those who say the solution lies in realizing that we fixate on just one kind of intelligence—linguistic, rational thinking—to the exclusion of others, and that we’d be better served by nurturing multiple intelligences, including musical, interpersonal, intrapersonal, spatial, bodily-kinesthetic, naturalist, and logical-mathematical. That’s good advice as far as it goes. But we’re unlikely to heed it sufficiently until we acknowledge why we came to rely so much on linguistic intelligence in the first place: it gave us power over our environment and over one another. So, our dilemma is as much one of ends (power) as means (language-based intelligence). In addition to needing a counterbalance to linguistic intelligence, we also need a way to check our individual and collective pursuit of excessive power.

As we’ve grown our population and our per capita consumption rates, we’ve been taking habitat away from other organisms. As a result, nature is in full retreat. Vertebrate and invertebrate animal species have suffered average population declines of 70 percent in the past 50 years, and thousands of plant species are endangered as well.
