Why is simple living so complex? (Part 3)

P1000676-small butterfly in gardenSimple living is complex, because our society has made it complex. What should we do about it?

The reason I’m so concerned about simple living, even though it’s tricky to define and almost impossible to practice, is that consumerism is destroying the planet on multiple fronts. We need simple living, on a massive scale — and especially in the advanced industrial countries — to save the ecosystems that support the existence of all animals on the planet. And no, veganism is not enough. If we keep burning coal, driving cars, and overpopulating the earth, veganism will just slow down, but not stop, the destruction. Continue reading

Abandoned house in Detroit. Is this the future of simple living?

Simple living is important given the environmental crisis. The human impact on nature is colossal and threatens all life on the planet, including eventually us, and we need to lessen that impact as much as we can. But in the United States, it is easy to consume and hard to live with less, just because of the way our society and our economy are structured. Why is this? Continue reading

Detroit - abandoned house - Delray

An abandoned house in Detroit.

Simple living should be a simple idea, but it’s not. The basic idea of living on less is an old idea, practiced by such people as the Buddha, Jesus, Epicurus, the Quakers, Thoreau, and Gandhi. Given the environmental crises that we now face, and given huge income inequality, simple living would also seem to be a timely idea.

The problem is that our society makes increased consumption easy, under the banner of “economic growth.” Trying to consume less, rather than more, is officially discouraged; someone trying to consume less is bound to run into problems. Continue reading

Fifteen Billion Vegans?

people crowd image wikimediaSometimes 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

A quick “limits to growth” bibliography

Earth

Earth

At my talk on Saturday night, several people indicated an interest in a bibliography for people who want to read more about “limits to growth” issues. I recognize the need for more information on this subject, but on the other hand, I feel a bit ambivalent about throwing inquiring minds into what is possibly a literary and scientific briar patch. If I try to “improve” the bibliography and explain what each book contains that is of value, the project could spin out of control, and instead of a blog post I might wind up writing another book.

Talk on “Environmental Destruction and Livestock Agriculture”

Keith AkersIn 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.

Megafauna Extinctions and Overpopulation

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

Earth Day Veganism

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. Continue reading

Degrowth and Veganism

"Degrowth" is something natural and beautiful

“Degrowth” is something natural and beautiful

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 Drought in California

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 — Review

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

God is not going to put more oil in the ground

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

Soil Erosion — is anyone paying attention?

Over a month ago, Reuters issued a widely-mentioned (but not widely discussed) press release on soils.“Only 60 years of farming left if soil degradation continues,” reads the release. It quotes some United Nations officials, warning of the problems of soil erosion.

Is anyone paying attention? In an ideal world, the public would be outraged by this. Congressional committees would study the problem. Students would demand courses on soil preservation. But back in the real world, farmland just isn’t that big of a deal. After all, agriculture is just a very small part of the U. S. economy. We could also debate whether this is an exaggeration. Perhaps we have 100, or even 200 years of farming left! Continue reading

Peak oil may be almost here

“Predictions are difficult, especially about the future.” This aphorism is nowhere more applicable than when predicting the date of “peak oil” — the maximum point of world oil production. In case you hadn’t noticed, oil prices are falling dramatically. Until about six months ago, oil (“West Texas Intermediate”) had hovered for several years in the region of $100 a barrel, reaching $107 on July 23. But by last Friday (December 12), it was below $60. If we’re close to peak oil, and oil is getting scarce, shouldn’t the price be going up? What happened, and why?

Are the Economists Hopeless on Environmental Issues?

The world has serious problems, such as climate change, peak oil, and resource depletion generally. Economists should be leading the charge on these types of issues, but except for the very few “ecological economists,” like Herman Daly, they say increasingly strange things about a parallel world which seems to have only a tangential relationship to the one in which we actually live.

A case in point is the recent book The Climate Casino (2013) by William Nordhaus. His book is quite insightful on several levels. The Climate Casino is a disturbing book, but unfortunately some of what makes it disturbing is not intentional on the part of the author.
