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?

834: Do Americans Know How to Prepare Food From Scratch?

on August 25, 2025 in Podcast

Late summer means produce at peak ripeness, especially peaches and heirloom tomatoes. Regular readers of my blog and subscribers to my newsletter have read of how my volunteering to bring overstock food from stores to places that give it to anyone for free has led to my getting for free amounts I can barely keep up eating that people turn down. This episode shares a saga of my confusion and exasperation[…] Keep reading →

This week’s selected media, August 24, 2025: The Problem of Social Cost; Law, Property Rights, and Air Pollution

on August 24, 2025 in Tips

This week I finished: The Problem of Social Cost, by R. H. Coase: I heard about this paper months ago, or maybe years. I read it because it came up in the Cato Institute podcast I wrote about in Libertarians confused on pollution, sacrificing their core values. At the root: lack of hands-on practical experience. I believe I see Coase’s starting point that conflicts don’t necessarily mean one person harming[…] Keep reading →

The problem with sleeping in summer weather in cities

on August 23, 2025 in HandsOnPracticalExperience, Perception

You’d think the problem with sleeping in summer weather would be the heat and humidity. I wake up sweating several nights per summer and it’s annoying. I don’t want to touch the sheets and it’s hard to fall back asleep. Still, I think of many places that are hotter and more humid than here where people have lived for thousands of years. Also, after a few nights of it, I[…] Keep reading →

When did you last prepare a full meal from scratch, not one packaged product?

on August 22, 2025 in HandsOnPracticalExperience

I wrote last week about how people decline free produce in my post More fresh juicy local peaches and heirloom tomatoes than I can handle, saved from waste by rich and poor alike. The people declining them include from homeless, probably crazy maybe homeless people as well as volunteers who appear mainstream, likely without a worry about money or food. Here’s an heirloom tomato I got for free that many[…] Keep reading →

Does anything tear family and communities apart more than flying?

on August 21, 2025 in Nature

I value family. Extracting fuel and minerals leads to things that tear families apart, like making them refugees, child labor in dangerous mines, people living far from the homes they grew up in, causing people to die young, and more. Valuing family is one of the main reasons I don’t fly. I don’t want to tear families apart. Likewise with communities. I don’t want to fund tearing communities apart. Can[…] Keep reading →

What you pay for when you buy gas, plane tickets, and plastic: lobbyists (also more extraction)

on August 20, 2025 in Stories

I was browsing OpenSecrets’ page on lobbying by “the fossil fuel lobby.” Who is OpenSecrets? They track who lobbies whom in the US. According to its site: “OpenSecrets is the nation’s premier research group tracking money in U.S. politics and its effect on elections and public policy. We provide comprehensive and reliable data, analysis and tools for policymakers, storytellers and citizens.” Their page on climate change lobbying is sobering. Here’s[…] Keep reading →

Read my plucky quote in today’s Washington Post

on August 19, 2025 in HandsOnPracticalExperience, Stories

The Washington Post‘s Climate Coach column by Michael Coren quoted me today. Here’s the part with my quote, which responded to his column last week about people figuring out solar on their own when they can’t install it on their buildings, which is my case. Did I let my coop board or the Department of Buildings stop me? No, because I live by values including Do Unto Others As You[…] Keep reading →

Imagine the density of litter was birds and mammals. That’s what our world was like.

on August 18, 2025 in Nature

I haven’t posted about the book The Once and Future World by podcast guest J. B. MacKinnon lately, but it’s one of the more eye-opening books I’ve found on the environment. He asked, researched, and answered how nature looked before modernity impinged on it. In case you worried, he qualified that nature didn’t exist in a perfect state, let alone a static one. It changed all the time. Still, he[…] Keep reading →

This week’s selected media, August 17, 2025: Black Hole Blues, If You Can Keep It, several essays by Woodrow Wilson, The White Man’s Task

on August 17, 2025 in Tips

This week I finished: Black Hole Blues and Other Songs from Outer Space, by Janna Levin: Somehow I started receiving Janna Levin’s Substack (that Is, Substack spammed me, though I doubt Levin caused it). I looked her up. She teaches physics at Barnard. I got my PhD at Columbia and worked with a professor at Barnard, who was one of my main reasons for returning there after starting graduate school[…] Keep reading →
