As promised, here is a commentary on "the end of the world," as envisioned through the thinking of one anthropologist, Anna Lowenhaupt Tsing, and applied to close-to-home circumstances in Iowa. For many here and on Earth, the world of the 20th century has ended already, and we struggle on in the ruins to find sources of hope and meaning. If you value this writing, let me know somehow - Substack posting itself may be another activity in the ruins of recent desires and dreams.

A Commentary on Human Ecologies

08/14/2026

I have two Substack posts in the works, so please be patient with me. One requires a little research and some map-making, and my GIS platform has become glitchy. Microsoft probably is to blame; at least the company makes a good scapegoat. (I’ve tried downloading again.)

The other one you’ll likely see sooner. The working title is “The End of Today’s World? A Commentary on Human Ecology.” It is inspired by a book by anthropologist and colleague Anna Lowenhaupt Tsing, The Mushroom at the End of the World. You’ll have to read the post to understood what Tsing means by “the end of the world,” because it’s not the obvious one, an apocalyptic event like the shutdown of the Gulf Stream Current or nuclear war.

I’ll “see” you soon!

Stray thoughts sometimes organize into coherent ideas. See "A Note in Passing" at my Substack site. Thanks!

Botanists have made rankings of naturally occurring plants that tell, based on expert opinions, how sensitive a given plant species is to disturbances to its ecology: its typical plant communities, the soils in which it grows, and other factors.

After a lull, here's my latest Substack post. This one introduces the fungi that cause wood rot. Wood decay is mostly beneficial to us and the rest of the life world. Enjoy and subscribe if you like this and others of the sixty-some posts I've written to date, all on ecology in some way.

Small, unnoticed things often run our world: gut bacteria, ants, mycorrhizal fungi, and plant gall makers. In this post, I explore a little about the insects and mites in the Midwestern US that make galls on plants and the insects that form mines on plant leaves. One or two may be familiar, and you may have seen damaged leaves and wondered what happened. Often, one species specializes on a specific plant and creates and identifiable gall or leaf mine. Ah, but I'm rewriting the post. I hope you find it informative and enriching for your outdoor time.

From the microworlds of pollinators (the last post) to overarching cultural sea changes (this one), I don’t mind prodding your nest to start some thinking about the need for changes. My thinking applies to more than just the central United States, and I am not the first to think in this direction. Some of those others are in the bibliography.

Here is a piece on pollinators: their biodiversity (not just bees), a little on their social organization, and our impacts on them (overall negative). Photos show a few of the hundreds of species present in Iowa and the Midwest. Every person should have some basic understanding of pollination and pollinators, and our actions and policies need to respect their existence, for our sake and theirs. As always, consider a paid subscription or an unpaid one, or at least a follow. Thanks kindly.
