This pandemic is a pivotal event, not just for vegans, but for almost everyone on the planet. There’s a lot that we still don’t know. But there can be no doubt that this pandemic is a consequence of our treatment of animals. Continue reading
NOTE (December 14, 2020): I’ve now expanded and revised this post here.
The historical Jesus, as I’ve argued elsewhere, was clearly vegetarian. To recap: (1) The controversy in the early church over vegetarianism shows that the leadership of the early church promoted vegetarianism and opposed animal sacrifice. (2) The testimony of later Jewish Christianity echoed and preserved this vegetarian, anti-sacrifice tradition. (3) Jesus himself was killed after disrupting the animal sacrifice business in the temple. But can we say that Jesus was a vegan? This is somewhat trickier. Continue reading
By now, many people have heard about “clean meat” — also known as “lab-grown meat,” “cell-based meat,” or “cultured meat,” among other monikers. It’s meat that doesn’t come from slaughtering an animal, but through cultivation of meat cells in a lab. No slaughtering of animals is required.
Now the question is, is clean meat vegan? Continue reading
The recent impeachment fiasco has drawn further attention to the rise of instability and polarization in the United States. In Ages of Discord, Peter Turchin predicted that this would continue. In his blogs, he states: “In my opinion, the greatest danger for us today (and into the 2020s) is not the rise of a Hitler, but rather a Second American Civil War. . . . we are already in a Cold Civil War.” Turchin foresees “rising instability in the USA, probably peaking with a major outbreak of political violence in the 2020s.”
Yikes! Continue reading
Ages of Discord. A Structural-Demographic Analysis of American History. Peter Turchin. Beresta Books, 2016.
Are we headed towards a new civil war? Can we learn from history? Peter Turchin thinks so, and his recent book Ages of Discord is a reinterpretation of American history, coming right down to the present day. Turchin has an interesting and insightful twist on the American Civil War of 1861–1865, which has parallels with our situation today.
In case you’re new to Peter Turchin, check out my review of his previous book Secular Cycles or his blog. Ages of Discord does for the United States what his earlier book Secular Cycles, co-authored with Sergey Nefedov, did for ancient Rome, and medieval Europe and early modern England, France, and Russia. Civilizations go in cycles; they rise, and then they decline. Continue reading
The devastating Australian wildfires have reinforced the impression that climate change is the world’s number one environmental issue. But the threat of peak oil is also still very real. Fracking is becoming more problematic and difficult to finance; public and private debt is multiplying; and thanks to Donald Trump, political instability threatens to spiral out of control. Gail Tverberg plausibly argues that because of these kinds of problems, we will soon face a recession much worse than the Great Recession — something like a near-term economic collapse.
Would economic collapse mean, at least, that we can relax about climate change, due to greatly reduced industrial activity? Gail Tverberg thinks so. “If the world economy is headed toward near-term collapse, climate change shrinks back in the list of things we should be worried about.” Continue reading
Sulfate aerosols are a fatal flaw in most plans to stop climate change, including most versions of the “Green New Deal.” Specifically, these plans—based on reducing fossil fuel emissions—may actually precipitate the very problem that they are designed to fight, propelling the climate past critical tipping points and creating a permanently hotter planet.

No One is Too Small to Make a Difference. Greta Thunberg. Penguin, 2018, 2019.
Last October 11, Greta Thunberg made an appearance in Denver. When she announced that she would not fly even to climate conferences, I despaired of ever being able to see her in person. And yet here she was, right in our own city, and we got to see her! I don’t remember exactly what she said. However, much of what she said was doubtless in this short book, which is a collection of her speeches.
It is well worth a look. When you read the whole thing through (at 108 pages, it’s not long), it is even more radical than you probably think of Greta Thunberg as being. Continue reading
Flying harms the climate. Air travel is growing rapidly. Its net impact is nearly twice as great as the impact of the CO2 emissions alone, much greater than that from cars. Air travel creates nitrous oxides, water vapor, sulfate aerosols, soot aerosols, and contrails. Noted climate activist Greta Thunberg famously went out of her way to avoid flying to a climate conference on the other side of the Atlantic.
So should we all stop flying, or at least avoid flying as much as possible? In a recent New York Times opinion article, Costas Christ (of Beyond Green Travel) argued that flying as part of wildlife tourism may actually be climate-friendly. Continue reading
We Are The Weather. Saving the Planet Begins at Breakfast. Jonathan Safran Foer. Farrar, Straus, and Giroux, 2019.
There is now a growing chorus of well-known popular books on the subject of climate change. Everyone from Al Gore to Naomi Klein has gotten into the act. Jonathan Safran Foer has outdone them all: BECAUSE, almost alone among such writers, he discusses livestock agriculture in some depth. He knows this implies veganism and addresses, in a very personal way, the difficulties of following a vegan diet.
Foer believes that livestock is about HALF of our climate problem — in line with the Goodland and Anhang article “Livestock and Climate Change,” which he discusses. Foer understands the role of livestock in the climate issue better than most vegans. While FAO has said that 14.5% of human greenhouse gas emissions come from livestock agriculture, the reality is more like 51%!
Greta Thunberg and George Monbiot have made a short and excellent YouTube video on forests and climate change. Their thesis: to deal with climate change, we need to eliminate fossil fuels, but this alone will not be enough. We also need reforestation. Key quote: “There’s a magic machine that sucks carbon out of the air, costs very little, and builds itself: a tree.” Plant trees, suck carbon out of the air. What’s not to love?
What they don’t mention is veganism. To reforest on a scale that will be significant we need to drastically reduce the land dedicated to the livestock industry. Continue reading
After the roundup and slaughter of geese in Washington Park, an article by Michael Roberts appeared in Westword, “Things Denver Should Care About More Than F*cking Geese.” Flynn’s argument was, in effect, “what about crime, what about homelessness, and what about affordable housing?”
My response is—”what about water? What about living space? Where, exactly, do you think you’re living?” There’s already insufficient water and land for everything that people want to do in Colorado. The “goose problem,” at its heart, is about living space. Continue reading
Some Denver residents are still unaware of the roundup and mass killing of over a thousand Canada geese in Washington Park and other Denver city parks, which took place toward the end of June. The city claimed that the geese were a health problem; and the goose meat is going to the homeless.
Before getting to the rationale for the mass killing of innocent creatures in our parks, it’s worth reflecting on the irony of giving their meat to the homeless. The meat is likely tainted with pesticides and metals, and a few years ago some city officials seemed to think that this precluded feeding the meat to the homeless. Evidently the city has now resolved its doubts on that score. The city also recently defeated, overwhelmingly, Initiative 300, which in effect would have legalized homelessness in Denver by repealing the “camping ban.” Congratulations, homeless people! You won’t be able to sleep anywhere — but you WILL get some goose meat of questionable quality. Continue reading
Whatever happened to the estimate that 51% of all human-caused greenhouse gas emissions are from livestock agriculture (“Livestock and Climate Change,” Robert Goodland and Jeff Anhang, WorldWatch, Nov.-Dec. 2009)? This certainly supports the vegan cause, but is it scientifically valid?
This claim revolves around how much of an impact human land use has on the carbon cycle. What difference would it make if we didn’t have any livestock industry today? The areas now used to graze livestock, or grow crops for livestock, would revert to their natural vegetation, which in many cases would be forest areas. A new article published earlier this month in Science now gives us a better idea of the potential of reforestation. Even excluding existing forests, urban areas, and farm areas (!), reforestation could store around 200 gigatons of carbon, which is about two-thirds of the carbon humans have put into the atmosphere since the industrial revolution, and thus getting rid of 25% of the CO2 currently in the atmosphere.

Here are the top 10 things to think about when considering the effect of food on the environment:
1. Humans and their livestock now constitute over 95% of all the large animal biomass on the planet.
