The Myth of Scarcity and Conclusion

The following is an excerpt (and rough draft) of a chapter I’m working on about sustainability. I have a limit of 2000-4000 words. As usual I’m trying to cram as much as possible into that limit. Much of this rehashes (and in some cases pillages) other writing I’ve done on the blog, but hopefully the synthesis brings out something new. I will be posting excerpts here for feedback and your reading pleasure as they are finished. My working title is “Why Recycling Doesn’t Matter”.

We have successfully segregated many disciplines and fields of study from each other. One of the most glaring cases of this is the division between environmentalism and economics. Politicians of various stripes can often be heard claiming that protecting the environment will cost jobs and hurt the economy. Those who argue for environmental regulation also buy into this myth by trying to argue that it will not hurt jobs, but potentially fuel a green technology revolution spurring economic growth. Both sides continue to base their arguments on the unquestioned belief in the necessity of economic growth. E.F. Schumacher explains this well,

“From an economic point of view, the central concept of wisdom is permanence… Nothing makes economic sense unless its continuance for a long time can be projected without running into absurdities. There can be ‘growth’ towards a limited objective, but there cannot be unlimited, generalised growth…The cultivation and expansion of needs is the antithesis of wisdom.”[1]

“The cultivation and expansion of needs” is at the very heart of our consumer economy. Advertisers and marketers are paid large sums of money in order to convince us that we “need” the products of the companies they represent. The problem of sustainability can be summed up as the modern confusion of the difference between “needs” and “wants.” Continue reading

The Myth of Technological Salvation

If agriculture had been the only discovery that attempted to “free” us from nature, we as a species would have quickly run into the same problem as any other species which overruns its ecosystem. We would have destroyed the very things upon which we depend. More likely, we would have been forced to find a balance between the agriculture required to support settled human populations and the needs of the ecosystem to maintain wild game, domesticated livestock, topsoil and fertility.

What made it possible to temporarily overcome the limitations of ecosystems once more was the discovery of abundant hydrocarbons in the form of fossil fuels. This discovery mad possible innovations which powered automobiles and factories. Today the fingerprints of oil are everywhere. If a product has plastic in it, it is dependent on oil. The electricity that power our light bulbs and devices as well as what drives our vehicles, transports our products and mows our lawn are dependent on oil. Oil permeates our modern life. The process to create petroleum takes millions of years, yet our consumption of fossil fuels continues at a rate well beyond any possibility for renewal. The use of fossil fuels as the primary source of energy which makes our current global civilization possible is the very definition of unsustainable. Continue reading

The Myth of Control

One of the things that distinguishes homo sapiens from other species is the degree to which we are able to manipulate our environment. Other species also manipulate their environment. Beavers build dams. Birds build nests. However, beavers and birds are not capable of destroying the ecosystem on which they depend. There are cases where a species overruns their ecosystem. For example, when natural predators are absent a species might become overpopulated and eventually deplete their food source. The difference is that in the case of non-human species they quickly find themselves subject to the laws which govern ecosystems and face disastrous results with massive die-offs and possibly extinction. In other words, non-human species have a limited ability to manipulate their environment and generally are subject to the restraints that make healthy ecosystems function properly with give and take between species and a balance between predator and prey, plants, fungi, animals, bacteria, etc. Continue reading

The Myth of Human Difference

Sustainability is one of those words in our culture that have been so thoroughly abused as to almost lose all meaning. Like the words “green”, “organic”, “natural” or “eco-”, sustainable is often appended to a wide variety of terms such as “sustainable growth”, “sustainable development”, “sustainable design”, “sustainable travel”, “sustainable style” or even “sustainable websites”. This is particularly unfortunate as it is one of the words we most desperately need to understand, if we hope to have a viable future for the continuation of our species. Sustainability, most simply, is the state in which a process or system is able to continue indefinitely without depleting the resources on which the system or process depends.

Many of our problems related to sustainability stem from some basic assumptions about who we are as human beings and how we relate to the non-human world. Most of us in the Western world have been enculturated into some powerful myths that continue to prevent us from understanding sustainability and our place in the world. The myth of human difference, the myth of control, the myth of technological salvation and the myth of scarcity all conspire to keep us committed to a framework that has set us on a trajectory toward ecological disaster. In this chapter we will explore these myths and their impact on how we think about sustainability, who we are as human beings and how we relate to the non-human world. Continue reading

What Shall We Eat? (Lev 25:6-7, 20-22)

In reading the Jubilee once again and Walter Brueggeman’s commentary on it from Finally Comes The Poet , I was struck by two particular aspects of this passage that I had missed previously. The first relates to a question that I think many people think of, if not ask explicitly, when thinking about the practice of letting fields lie fallow for an entire year. The text itself asks, “What shall we eat in the seventh year, if we may not sow or gather in our crop?” (Lev 25:20). With global population now at 7 billion, we don’t really have the luxury of following this kind of practice right? Well, first let’s listen to the text and see if it has anything to say to a world with 7 billion people.

This question is the central theme of this blog, “What shall we eat?”. Perhaps in the imagination of the agrarian readers of Leviticus it was almost as impossible as it seems to us to feed yourself without practicing constant and intensive agriculture. The answer to the question of how they will eat if the land is not in production is found at the beginning and middle of the chapter:

The Sabbath of the land shall provide food for you, for yourself and for your male and female slaves and for your hired servant and the sojourner who lives with you, and for your cattle and for the wild animals that are in your land: all its yield shall be for food.

The land will yield its fruit, and you will eat your fill and dwell in it securely…I will command my blessing on you in the sixth year, so that it will produce a crop sufficient for three years. When you sow in the eighth year, you will be eating some of the old crop; you shall eat the old until the ninth year, when its crop arrives. (Lev 25:6-7, 19, 21-22)

So, here’s the radical thought to sit with for a second: The earth produces food without the help of human beings. Some of the plants that we consider a nuisance and call weeds are actually edible. Before you start foraging for dinner among your local neighborhood make sure you get educated. Back in the day it was common knowledge what to eat and what not to eat. We have lost that common knowledge and now must rely on field guides and experts to learn what we can forage in our local bioregion. This fact, that the earth supports all of the life on it without the help of human beings, is the central idea of the Sabbath practices which culminate in this year-long practice of cultivating the mindfulness of our place within the creation that sustains us.

Now, the global population when Leviticus was written between 538-332 BCE was somewhere in the neighborhood of 200 million. That’s only 3% of the current world population of 7 billion. So while the advent of agriculture had already begun to significantly increase global populations, the pressures of population on the land to produce was minimal compared to today. I’ve heard lots of different figures about what the carrying capacity of the earth is in terms of human population from 10 million all the way up to 9 billion. Regardless, it is clear that this practice of an entire year without production would not support current and future levels of population.

Now, you careful readers will point out that in the text God promises a bumper crop just prior to the Jubilee that will carry them through the fallow year and then some. While it may seem like this is the product of human ingenuity and hard work, any good farmer will tell you that there’s really not much you can do to get yields of the magnitude suggested by this passage. Sure there are bumper crops, but not because of anything any farmer did to make it happen. Studies have shown that even our best technological attempts to improve yield can’t out perform nature. So, the provision of food to carry people through three years on one year of production is a miracle intended to tell them, “Quit worrying about it and trust me”.

So, we have created a world which is completely dependent on the efforts of human beings to maintain and sustain itself. This clearly contradicts the heart of the Sabbath practices which reorient our lives around the fact that we are not owners in an absolute sense and the maintenance and sustenance of life on this planet does not depend on us. What are the repercussions for a world in which we have transgressed this Sabbath boundary and made a world dependent on us, in essence making ourselves God? I suggest that this question, “What shall we eat?” reveals once again our addiction to control and domination and our complete disconnection from the land. The Jubilee is a radical act of faith in the ability of the creation to sustain itself and ourselves, if we are willing to understand the boundaries of the system as it was created.

Up next… Jubilee is Salvation.
