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.

The last Christmas Pagan Trees of the Season?

on March 27, 2026 in Visualization

I’ve already written a few posts this year wondering if I’ve seen the last discarded trees, but we cut down so many, it takes this long to discard them all. We could have left them standing. It’s almost April and people pay to chop down so many trees, I’ve seen them thrown out this month. I think I’ve seen the last for the season so I’ll post the last images[…] Keep reading →

More on Eric Williams’s “Slavery was not born of racism: rather, racism was the consequence of slavery”

on March 26, 2026 in Freedom, Nonjudgment

I found a piece that expanded on something I wrote in Sustainability Simplified about how racism developed. Since I found that we needed to change culture to restore sustainability, I’ve been learning about abolitionism and related issues, since abolitionism is an example of humans changing global culture where no one thought it possible, then it happened, started by a small number of visionary people. In my book, I wrote: Oxford-educated[…] Keep reading →

Did Paul Ehrlich Help or Hurt His Cause?

on March 25, 2026 in Awareness, Choosing/Decision-Making, Leadership, Nonjudgment, PollutionAndDepletion

Paul Ehrlich died two weeks ago. I read The Population Bomb a while ago and heard him speak in many interviews. I recently listened again to a few recordings of his and read a few articles of him. In each he was speaking to people who liked him and agreed with him so he spoke freely. In each he called people who disagreed with him “idiots” or something like “people[…] Keep reading →

See me in the Washington Post’s Climate Coach again

on March 24, 2026 in Doof

The Washington Post‘s Climate Coach column by Michael Coren quoted me today. Scroll down in the image or pdf below and you’ll see my comments on an app designed for packaged food and doof. They had to edit for space (asking permission, of course). Here’s the full text I wrote: Hi, I recommend a solution I prefer to Yuka, which doesn’t work for me since I don’t buy packaged food.[…] Keep reading →

Year 11, day 1 no flying

on March 24, 2026 in Addiction, HandsOnPracticalExperience, Nature, PollutionAndDepletion

I attended an event in midtown by Trump Plaza in midtown over the weekend. A friend who is very liberal said how uncomfortable the space made her feel. She also mentioned how she just got back from Mexico and planned to return there, as well as New Orleans, in the next few months. I didn’t point out to her how much of the cost of her plane tickets is funding[…] Keep reading →

Are we pseudoscientists?

on March 23, 2026 in Awareness, Nonjudgment

It’s difficult to empathize with people we disagree with. It’s difficult to look at the world as if you knew only what they knew and nothing of what you know that they didn’t. Many people seem unable to distinguish understanding and empathizing with someone from agree with or supporting them. I think part of our inhibition comes from fearing that we’ll find that we would have felt and done things[…] Keep reading →

This week’s selected media, March 22, 2026: Two documentaries: Ulysses S. Grant and Eugenics

on March 22, 2026 in Tips

This week I finished: Ulysses S. Grant—A documentary on the 18th President, part 1: Grant plays a big role in my new book as a role model. He was a broke farmer recovering from malaria. His wife’s family owned slaves, giving him an easy way to recover if he chose it. Meanwhile, his father refused to help him as long as he stayed with slaveholders. He had acquired a slave[…] Keep reading →

Would you have acted in the gravest historical times?

on March 21, 2026 in Choosing/Decision-Making, PollutionAndDepletion

People consistently say they don’t do what they believe is right regarding pollution and depletion because it won’t change the system. I point out that independent of what anyone else does, their personal pollution and depletion will hurt people who have not consented. They rarely even minimally decrease their pollution and depletion. I’m curious what people think they would have done under slavery, the Holocaust, Stalinism, or other dominance hierarchy.[…] Keep reading →

Environmentalists argue against sustainability with me

on March 20, 2026 in PollutionAndDepletion

I recently met with an environmentalist. The name isn’t important, but this person founded an organization devoted to justice around climate. The person and organization are highly regarded in their fields. Our conversation followed a common pattern. This person is pursuing standard practices of legislation, market incentives, and innovation to promote things like more scientific research, innovating efficiency and new legislation, but most of all, a transition to “renewable” energy.[…] Keep reading →
