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 →
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.”
In a recent Go Vegan radio interview, Leslie Goldberg (author of the Vicious Vegan blog) gave an account of a conversation she had with Bill McKibben. (McKibben is a noted environmentalist and a co-founder of 350.org.) Leslie asked McKibben why he didn’t talk about meat consumption as a cause of climate change. McKibben first pointed out that most of the growth in meat consumption comes from the developing countries. Somewhat irritated, he then asked (in effect) “how can you ask people who are just starting to be able to afford and enjoy meat, not to eat meat?”
This is an intelligent question, so I thought I’d attempt to answer it. Continue reading →
5280 The Denver Magazine recently featured an article on “Everyday Environmentalists,” presenting over 40 ways to live greener. Pointing out that Coloradans are not as environmentally virtuous as we may think we are, the article featured excellent advice on such topics as home insulation, composting, gardening, biking–the usual and more. Some items were very detailed, such as the advice to buy a live Christmas tree instead of an artificial one, and then plant it outside. Readers who hike popular mountain trails were encouraged to go during the week so as to increase the likelihood that they will stay on the trail and minimize trail deterioration. Yes, yes, yes, I’m saying to myself as I read, but when do we get to the huge environmental impact of meat consumption? Continue reading →
