Does breathing contribute to climate change? With every breath we take, we breathe in oxygen and breathe out carbon dioxide. Carbon dioxide is a greenhouse gas. So are we contributing to climate change just by the act of breathing?
If someone knows a bit about biology, they might respond, “no, because new plants will replace the plants we have eaten, and the new plants will take up the carbon dioxide.” The actual answer is not some glib assurance that new plants will replace the old, but “it depends.” And when you spin out what precisely it depends on, it has very significant implications for how we address climate change.

Al Gore’s new documentary “An Inconvenient Sequel” is well worth seeing. Coming out a decade after “An Inconvenient Truth,” it makes one key point on which we all can agree: climate change is already happening, illustrated with collapsing glaciers, extreme weather events, and more. To his credit, Gore does acknowledge agriculture — in one sentence — but immediately adds that the leading cause of climate change is fossil fuel emissions.
Well, isn’t he right?
I would turn Gore’s statement around: without addressing livestock agriculture, we will not be able to deal with climate change. And here’s why. Continue reading →
Remember the very beginning of Cowspiracy, where the producers interview Bruce Hamilton representing the Sierra Club? Hamilton gives a litany of all the dire consequences of climate change, ending with a prediction of “climate wars.” He is then asked, “what about livestock and animal agriculture?” to which Hamilton innocently (and seemingly obliviously) responds, “well, what about it? I mean —”. This is the lead-in to Cowspiracy’s general theme that environmental organizations are either clueless or hypocritically silent about livestock agriculture and the environment.
If the producers of Cowspiracy had showed up at a local Sierra Club meeting last week, instead of interviewing Hamilton, Cowspiracy might have taken a very different turn. Continue reading →
The High Park Wildfire, June 10, 2012. U.S. FS photo.
Climate change is a lot worse than we thought. This is catching even the climate scientists by surprise, according to a widely-cited story from the Thompson Reuters foundation. The World Meteorological Association reported record temperatures in June — for the 14th straight month. David Carlson, director of the WMO’s climate research programme, stated that “what concerns me most is that we didn’t anticipate these temperature jumps.” They knew it was bad, just not this bad.
And why do you suppose climate change is worse than anyone thought? Has this question occurred to anyone? Continue reading →
We’ve been wondering for some time if major environmental groups would ever react to Cowspiracy, the 2014 documentary making the case that livestock agriculture is the most destructive industry on the planet today.
Well, there’s good news and bad news! The good news is that one group, the Union of Concerned Scientists (UCS), is now publicly discussing Cowspiracy. The bad news is that this comes in the form of a rather strange review which Doug Boucher, a scientific advisor to the UCS, has posted on the UCS web site. Continue reading →
Sometimes I hear vegans, in the context of discussions of world hunger, say things like, “on a vegetarian or vegan diet, the world could easily support 10 or 15 billion people.” Actually, I myself have said things like this, so I’m not exactly pointing a finger here. “On a vegetarian diet, the world could undoubtedly support a population several times its present size” (A Vegetarian Sourcebook, p. 137).
Could we, really, support fifteen billion human beings on a vegan diet? Continue reading →
Last December, Sailesh Rao published a study on the “Lifestyle Carbon Dividend.” I corresponded with Sailesh about this and have posted the interchange below. I have also posted some of the relevant parts of his poster when my questions related to them. This interview may be a bit technical for some of my readers, but I learned something from this exchange myself and hope that it is helpful. Key quote: ” On average, native forests sequester more than ten times as much carbon per unit area [compared to grasslands or pasture lands].” Continue reading →
In case you don’t have time to read through Sailesh Rao’s paper on “the lifestyle carbon dividend” (see previous post), you’re in luck. Sailesh has a video about his paper (about 10 minutes). This video is his introduction of the documentary “Cowspiracy” to the European Parliament. I almost missed it because I thought to myself, “I’ve already seen ‘Cowspiracy,’ so I don’t need anyone to ‘introduce’ the movie to me.” Well, it is an introduction to “Cowspiracy,” but it’s more than that. Continue reading →
Last December, Sailesh Rao and two of his colleagues made a presentation to the American Geophysical Union, entitled “The Lifestyle Carbon Dividend.” The key point of this paper was that by simply stopping livestock agriculture, we could sequester a lot of carbon and thereby decrease the carbon dioxide levels of the atmosphere. The reason is that grazing land occupies much of the planet’s surface today. In the absence of livestock agriculture, much of this area would revert to forests, which incorporate much, much more carbon than grasslands or pasture. How much carbon could we sequester in these new forests? More carbon than has been released into the atmosphere since 1800.Continue reading →
In case you’re in Denver this Tuesday (September 29), I’ll be giving a talk at the University of Denver on “Environmental Destruction and Livestock Agriculture,” sponsored by the DU Environmental Team. It will be at 8 p. m. in room 253 of Sturm Hall (2000 E. Asbury Ave, Denver, Colorado). There will be a quick overview of basic environmental issues relating to the livestock industry, such as climate change, resource depletion, and mass extinctions. It’s free and there will be vegan goodies served. For more details, check out the Denver Vegans Meetup site.
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 →
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 →
