“What about ambulances, fire trucks, and hospitals?”, some people ask. “Don’t they help us and require polluting?” “Checkmate,” I can almost hear them thinking. “We can’t get rid of them, so we have to keep culture going as is.” Meanwhile Hawaiians lived sustainably over centuries, long past when Malthusian collapse, if inevitable, would have happened. Hawaiians lived on their own for centuries, longer than the time since the Enlightenment to[…] Keep reading →

The opposite of pollution is loving your neighbor as yourself. After all, do you keep your garbage in your house forever? No, you get rid of it. That means you have your neighbors deal with it, as you would not deal with it yourself. Does it matter that those neighbors aren’t your next door neighbors but are poor and distant? How can you love your neighbor as yourself except not[…] Keep reading →

I once read about two percent of the US is paved. Two percent of fifty is one, implying about one state worth of the US is paved. How do we reach the point of paving an entire state’s worth of land? It seems to me: First we tread over similar land to create dirt paths. Then we tread over them enough that rain makes them muddy enough to make them[…] Keep reading →

One of the more common responses to my suggesting eight billion people live sustainably, along with governments and corporations, is to suggest thing after thing the other person thinks wouldn’t work. “What about cars? How will people get around?” “What about family?” “But they won’t be able to create energy.” “What about police and ambulances?” The list of attempts to challenge sustainably goes on. They aren’t being rational. They’re just[…] Keep reading →

Ali Horriyat and I have become friends since we started recording together. He hosts the Compassiviste Dialogues podcast. Friendship doesn’t mean always agreeing. On the contrary, I consider one of the roles of friendship—true friendship—is to disagree when appropriate and to confront a friend when you think they’re wrong, deserve criticism, or the like. People who aren’t friends may hold back from confrontation. That holding back may be polite, but[…] Keep reading →

Would you drive a car that sent its exhaust into where you sit? Would you fly in a plane that sent its exhaust into the cabin? Would you dispose of all your garbage by digging a hole in your yard and keeping it there forever? If you send the exhaust and garbage into the rest of the world, it doesn’t go away. You’ve made your problem your neighbors’ problem. If[…] Keep reading →

On September 30, 2021, I unplugged my fridge, aiming for 8 months. I had unplugged it based on an article on one of my favorite sites, Low Tech Magazine: Vietnam’s Low-tech Food System Takes Advantage of Decay. I learned much of the world uses less refrigeration than Americans. We think of fridges as keeping food fresh, but other places have The first time I unplugged, I made it 3.5 months.[…] Keep reading →

You know the usual schematic diagram of the greenhouse effect. Here are a couple for reference: and What’s missing? Humans creating power for ourselves creates heat. It happens if we create it through burning fossil fuels, using nuclear power, and even fusion. Using solar panels absorbs extra heat. I hope you respond that whatever heat we produce is negligible. Today it is, but since industry and our current lifestyles require[…] Keep reading →

I was invited to speak to a New York City public high school class on astrophysics. About fifteen minutes in, I mentioned how I answer a common question people ask of me: “Do you still use your physics degree?” I consider my sustainability leadership work an application of science so, yes, I still use the science I learn, but not in a white lab coat in a lab. I thought[…] Keep reading →
