My Mission

My mission is to help change American (and global) culture on sustainability and stewardship from expecting deprivation, sacrifice, burden, and chore to expecting rewarding emotions and lifestyles, as I see happen with everyone I lead to act for their intrinsic motivations.

In my case the emotions have been joy, fun, freedom, connection, meaning, and purpose.



Systemic change begins with personal change.

Some of my values. What are yours?

This week’s selected media, February 1, 2026: 8 Billion Angels, Is Atheism Dead?, I Feel Love

on February 1, 2026 in Tips

This week I finished: 8 Billion Angels, directed by Terry Spahr: I’ve become friends with Terry since first watching his documentary on overpopulation years ago. He recently released it free on YouTube. I recommend it. Here’s the movie’s page: https://8billionangels.org. From Scientific American: Eight Billion People in the World Is a Crisis, Not an Achievement The major driver of plant and animal loss is habitat destruction caused primarily by the[…] Keep reading →

My Spodek Method commitment to make water ice from snow: A photo essay

on January 31, 2026 in Creativity, HandsOnPracticalExperience, Nature, Stories, Visualization

First, I grew up in Philadelphia, and in Philadelphia, we have something called “water ice.” It’s like cheese steaks in that it’s local. I didn’t know it wasn’t universal until I moved away. Elsewhere they call something like it Italian ice, but we don’t. Here’s an article on it from USA Today: What is Philly-style water ice? We explain how it’s made and where to get it. On to the[…] Keep reading →

Jobs don’t just mean working in a dominance hierarchy. They mean working for the whims of people with rank.

on January 30, 2026 in Freedom, Nature

Before the Holocene, our immediate-return egalitarian ancestors lived in environments in which each person could access their material needs. People who were hungry could, on their own, climb a tree, dig up a root, or hunt an animal. For needs like safety from predators, they’d have to cooperate with others, but they had the freedom and responsibility to make those relationships work. By contrast, living in dominance hierarchies mean that[…] Keep reading →

Criticism of Lomborg: The Lomborg Deception and other challenges

on January 29, 2026 in Nature, PollutionAndDepletion

I finished a few papers, books, and videos by Bjorn Lomborg lately, as well as books that refer to or rely on his work, like Superabundance and The Moral Case for Fossil Fuels. I follow up most books and movies I finish and find meaningful by reading and watching reviews, commentaries, criticisms (positive, negative, and other), and more. My criticism of Lomborg’s work stands independent of the accuracy of his[…] Keep reading →

I’m endlessly amazed at how the body acclimatizes to cold

on January 28, 2026 in Nature

I talk about this effect a lot in person because it keeps amazing me, not that it’s particularly insightful, but I love nature and this effect is part of it. If the temperature drops below 50F (10C) in September, I shiver and can barely stand it. I have to bundle up. Then in December it drops below freezing and 50F feels warm. I’m commenting on it now because we’re in[…] Keep reading →

Another time garbage nearly brought me to tears

on January 27, 2026 in Addiction, Doof, Habits, PollutionAndDepletion, SIDCHAs

Two days ago I posted My first time since starting not finding litter in Washington Square Park, because over six inches of snow covered it. Since I committed to picking up at least three pieces per day until three days pass when I can’t find three pieces to pick up, I wondered if the snow would make it possible. I also offered to take any bets that people would litter.[…] Keep reading →

Meditation thoughts: What is meditation?

on January 26, 2026 in Awareness, Doof, Freedom, Habits, HandsOnPracticalExperience, Nonjudgment, SIDCHAs

I lead a meditation group that meets in person a couple times a month. We’ve found we can get a laugh if we talk in the group about talking about meditation to others who don’t meditate by saying, “I can’t meditate. My mind is too crazy to empty it of thoughts,” or words to that effect. Why does it make us laugh? Because it’s like a knee-jerk reaction that betrays[…] Keep reading →

My first time since starting not finding litter in Washington Square Park, because over six inches of snow covered it.

on January 25, 2026 in Addiction, Doof, Habits, PollutionAndDepletion, SIDCHAs

I’ve committed to picking up at least three pieces of litter from the northwest corner of Washington Square Park since it became overrun with fentanyl, meth, and all that results from it during the pandemic. I decided I’d keep up the sidcha until three days passed in which I couldn’t trivially find three pieces of litter, as I wrote three years ago in On when I should stop picking up[…] Keep reading →

This week’s selected media, January 25, 2026: In the Mood for Love, Cool It

on January 25, 2026 in Tips

This week I finished: In the Mood for Love, directed by Wong Kar-Wai: It’s hard not to first mention this movie’s style in the qipaos, hair, make-up, ties, and music. Each dress and hairdo must have taken hours to get right each time, looked sewn-in. The word I keep coming back to for the style is: perfect. What a beautiful movie. But the movie covers more than style. Who hasn’t[…] Keep reading →
