A key cause of climate change
There is now more megafauna biomass (the total biomass of all large animals that are heavier than about 100 pounds) than there has been in recent earth history — indeed possibly in all of earth’s history. It seemed to be fairly constant at 200 million tons for literally hundreds of thousands of years. Then, starting with the industrial revolution and the huge surge in human population and the population of domestic livestock, megafauna biomass has exploded. It is currently about 1500 million tons, over seven times as much. And almost all of this increase has happened just since the industrial revolution.
Whoa! How did this happen? And do you think that all this extra animal biomass would affect carbon dioxide levels? Continue reading
Extinction is a hot topic these days. Megafauna — those “big animals” whose average size is 100 pounds or more — are going extinct at an alarming rate. There is huge popular sympathy for elephants, whales, tigers, giraffes, apes, and other animals endangered by human activities. At the same time, we face a huge paradox: there is more megafauna biomass now than there ever has been for past 100,000 years or so. How can megafauna become more prolific and yet so many species be faced with extinction?
There’s a simple explanation. The cause of megafauna extinctions is one particular megafauna species, namely us, and a number of other species that we have brought into existence, namely our livestock. Continue reading
Environmentalism requires veganism. Livestock agriculture is hugely wasteful of natural resources, and is the leading cause of climate change. And this is not to mention the California drought, species extinction, and deforestation — all exacerbated by livestock agriculture, and all threatening the basis of human life on earth.
But this works the other way as well. Veganism implies radical environmentalism. That’s because consumers who drive gas-guzzling cars, live in huge houses, and buy lots of toys really are doing more than just depleting the earth’s resources; they are endangering all animals on earth.

Degrowth graffiti in Paris - "Décroissance" = "Degrowth"
How can we deal with climate change, let alone peak oil, water shortages, deforestation, and everything else — given that truly effective environmental action would probably stop the economy from growing and totally change everyone’s lifestyle?
Our whole economy depends on fossil fuels, and our livestock-centered agricultural system is pillaging the earth’s biosphere. Veganism is surely part of the needed approach here. Continue reading
The California drought is not going away anytime soon. And guess what uses more water than anything else in California? Livestock agriculture.
The environmental reasons for veganism suddenly are getting more credibility and attention. The recent film Cowspiracy, and the San Diego based group Truth or Drought, have drawn needed attention to the environmental destructiveness of livestock agriculture.
The solution seems to be obvious. Some people get it, while others don’t. Still other people almost get it, but not quite. Continue reading
This Changes Everything: Capitalism vs. The Climate, by Naomi Klein. Simon & Schuster, 2014.
For Naomi Klein, the climate change issue changes everything: the only way to deal with climate change is to change capitalism. We need fundamentally to alter our economic system if we hope to save the planet. Her analysis is spot on and I hope that climate change activists and vegans will study and benefit from this book. The only criticism I would have is not that it is too radical, but that it isn’t radical enough. Continue reading
Siberian sinkhole in winter
There is some good news and bad news about the massive sinkholes in Siberia. The good news is, people are beginning to become very concerned about them! Some people (such as Alexei Portnov) are concerned for the obvious reason; this is a strong symptom of accelerated global warming.
The bad news is that the leading cause of concern is that “the sinkholes could pose a serious challenge to the quickly expanding gas industry in the area.”
Moral Tribes. Emotion, Reason and the Gap Between Us and Them. By Joshua Greene. Penguin Press, 2013.
What’s the best way to talk about moral issues? This is obviously something that activists worry about a lot, whether their cause is veganism, the environment, climate change, or anything.
According to Joshua Greene, the problem is not lack of basic morality, but in competing moralities. There are many different moral cultures or subcultures, which share among themselves certain ethical ideas which, to them, are obvious. But these ideas differ from those of other moral cultures — the “moral tribes” referred to in the title. Anyone who is interested in this problem, or in moral philosophy and moral psychology in general, should at least take a look at Moral Tribes. Continue reading
The Modern Savage: Our Unthinking Decision to Eat Animals, by James McWilliams. Thomas Dunne Books, 2015.
Industrialized animal agriculture is morally and intellectually bankrupt. Society is slowly but increasingly becoming aware of the cruel, unnatural, and environmentally harmful aspects of factory farms. But what is going to replace it?
Well-known food intellectuals such as Michael Pollan, Mark Bittman, Joel Salatin, and Jonathan Safran Foer have advocated returning to localized, more traditional ways of raising animals. Encouraged by some environmentalists and even some animal welfare supporters, nonindustrial animal agriculture has grown tremendously in the past decade. Continue reading
There has been a huge drop in oil prices since last July. Many environmentalists don’t know what to make of this. Some are saying that the fall of prices should get us to rethink the “flawed” argument for peak oil, or that it will “destroy the green revolution,” or that it reflects the “existential crisis” of the environmentalists. Earth First! has chimed in as well. How can there be a shortage of oil, if prices are falling? Continue reading
