Trying to buy back what we've lost

I had trouble deciding on what the title of this post should be. I will try to articulate why.

There is a model of environmental thought (of course, Western) which basically says that in the "development" of countries or communities, ecological harm necessarily grows, up to a point at which they have "developed enough" that they are somehow "satisfied" and can now start "caring" for the environment. What this explicitly means is that no matter where in the world you may be, ecological harm is necessary for you to be "prosperous," and for the citizens of that place to have a "high standard of living."

As I mentioned in my last post, there is a prevailing ethic that something is valuable only if it is assigned a dollar value. Something can be cared for only if we can quantify to ourselves what it is worth. Of course, such quantification is impossible and reckless in nature. Such quantification leaves in its wake uncountable losses to the wholesomeness of nature and the spirits of the people living there. What we do is the following - we convert the most important thing, our environment, into something expendable and movable (money), through degradation, and then use that expendable thing we've created to buy back the most important thing. Or at least we expect to. Speaking of entropy, there are losses here. There is something so profound about this second law of thermodynamics. In most every physical act, we can never fully realise a full potential, but rather a potential less than full. What this consequently means is that there is no way to fully recover the original conditions of a state by investing the same amount of effort we used in disturbing it. We have to invest more, and more, and more, and more.

Now, the people of Delray have been struggling with this very issue for a very long time - they have been surrounded by industry which has propelled the US as a leading superpower. This means that they have been surrounded by the effects of that industry - pollution and a degraded environment. As counter-intuitive as the second paragraph actually is, you might think that the people of Delray were then pretty well off...industry = money = clean environment. You would be sorely wrong for thinking so. The people of Delray have no other choice but to bear the consequences of such careless thought, and to be exploited by heretofore not being provided any sort of remediation, reparation or compensation, money, or anything else.

Now, I wondered about what the title of this post should be. Should it have been 'Trying to buy back what we've given away,' or 'Trying to buy back what has been taken from us'? Of course, it is a matter of perspective and of introspection. Maybe we haven't done enough to protect nature, and maybe we've faltered and disagreed, and we've just given it away, or in some sense allowed that. Or, on the other hand, maybe we've been oppressed into being subservient, into having absolutely no power in opposing the powerful forces of capitalism and economy from taking pristine nature away from under our feet, around our skin, and in our lungs. I would speculate that people from the past allowed it to happen, and that the people of today, say of Delray, feel that it was taken from them a long time ago, that this is a legacy that cannot be moved away from, that it is a legacy that will influence all decisions now and into the future. They might feel that there is no other choice but to live in a degraded environment.


There is a "community benefits agreement" (CBA) that is being proposed to compensate the people of Delray for the massive new bridge that is likely going to be built there. (...a joke, to me. "Benefits" is a cozy term to hide all of the costs of such violent behaviour.) They are contracts between citizens and those proposing to change their environment to ensure that some of the "positive" outcomes of change be passed along to the citizens. CBAs have only been a recent phenomenon, as Caleb told me last night. Yet in no way does the list of benefits, which I went over over the last week, fully address the dire state of affairs in Delray.

It is a matter of perspective. We can focus our attentions on the "state" or "country" as a whole and see that it is doing "well," or we can zoom in and focus our attention on the little parcels of the country and see that some of them are fine, while some of them are being exploited at the benefit of the "country." What we forget is that people, yes people, live in these small parcels, and they are the ones breathing in the noxious air, living on toxic soil, and cutting their limbs off for the "benefit" of the "state" and "country."

Guest blog #11 - Dr. Jack Edelstein's thoughts on conservation and entropy

"What do we mean by the term ‘energy conservation’ or more generally ‘resource conservation?’  At first thought, the answer seems obvious:  conservation means using less stuff, thereby making a smaller environmental footprint than would have otherwise been made, and avoiding a certain disruption to the resource base (e.g. biodiversity) that would have otherwise occurred.  What, exactly, is it that needs to be conserved, and how does conservation actually work?

From a practical point of view, absolute conservation would completely preserve the current status of the earth’s biodiversity -- by neither depleting any natural resource (e.g. wildlife, trees, water), nor by depositing any man-made matter onto the environment (e.g. trash, smog, and carbon).

There are four ways that we can conserve energy, and any other [non-renewable] resource -- 1) consume less, 2) eliminate waste, 3) increase efficiency, 4) substitute renewable.  We will describe each of these four conservation methods through the simple example of a shower. 

The first way to conserve is to actually consume less water by reducing the shower time, and/or by reducing the flow of the showerhead.  Another way to consume less is to lower the water temperature, thereby reducing the amount of energy used (in heating the water).

The second way to conserve is to eliminate or reduce waste.  We distinguish waste from excess by defining the former as the act of consuming resources without deriving any value -- as in the case of a dripping showerhead. Excess is much more subjective than waste -- e.g. taking a very long shower is not wasteful in the strictest sense (since some marginal benefit or utility is being derived), but at some point it becomes excessive in that the derived benefit is miniscule.

The third way to conserve is to increase efficiency by utilizing less resources in the creation of a given unit of output.  In the case of a shower, improved efficiency can be a low-flow showerhead, or a more energy-efficient water heater.  However, efficiency by itself does not lead to conservation, due to the Jevon's paradox (as explained in an earlier post by Darshan).

The fourth way to conserve is to substitute renewable resources for non-renewable ones.  An example is utilizing solar collectors to heat the water (instead of fossil fuel), and harvesting rainwater instead of drawing water from an underground aquifer.


                    Reduce         Eliminate     Maximize      Substitute   
               consumption        waste         efficiency      renewables   
Cost               Zero             Low       High          ???    

The expenses associated with these four conservation strategies range from zero to high cost -- depending on the level of technology required. Reducing consumption costs nothing since it is entirely a behavioral strategy.  Similarly, eliminating waste generally entails a behavioral approach augmented by a low input of technology. The ‘efficiency’ approach is generally technology-intensive and therefore expensive, and often risky.  Finally, the cost of substituting renewable for non-renewables is quite variable.  It is generally high in that it usually involves an advanced technology component, but it can also be low, as in the case of rain-water collection discussed above. 

A review of the academic literature as well as the general media reveals a strong bias toward energy conservation strategies that are based on the efficiency and renewable options -- the two more expensive options.  In other words, the two conservation approaches that cost the least and could have the most immediate impact -- i.e. to use less and to eliminate waste -- are the ones that are least supported, and often outright ignored. (There are a number of reasons for this, which will be addressed in a future post)

The power of Darshan’s project is that it represents by far the most cost-effective approach to conservation --  simply using less (though it may not actually be that simple to do).  By using absolutely less matter, Darshan is impacting the entire production chain associated with the consumption of physical goods.

Perhaps that’s why the name of this project is “Entropy”. If I understand the 2nd law of thermodynamics, one of the ideas it posits is that the physical world is constantly seeking a state of equilibrium, through a process defined as entropy.  As an outcome of the forces of entropy, the planet attained a state of equilibrium many millions of years ago, and this equilibrium was maintained until homo sapiens started roaming the earth.  The activities of humanity are increasingly disturbing this equilibrium, and the newly resultant equilibrium may become (or already is) inhospitable to sustained life.

The essence of conservation, then, is to understand that the equilibrium into which humanity entered was ideally suited to the evolution of homo sapiens and all other life.  Conservation entails respecting that equilibrium, and reduces our interference with it. Using less is the most powerful way we as individuals can conserve the planet."

Soap is waste

Here is a comment that I received from Matthew the other day about my post about Catherine Mohr's TED talk in which she challenges potential gut instincts on environmental action:

"For this post I agree with your reasoning in the ideal world but I think the world we live in is not so simple. I believe everything we use eventually loses its value to us and that value needs to be re-estabilshed somehow. In many cases materials that have lost value to use may have value to other organisms, which regenerate their value to us. It is interesting to me that you think of a sponge as something that does not become garbage. For example, I wouldn't use a sponge for a year. Also the soap that we use to clean the sponge is not re-usable and I would consider it garbage. So in my mind every comparison always becomes "what is the lesser of two evils." In many cases I believe we agree, if the material cannot be easily utilized by other organisms for something useful then we have thrown a wrench in the works. From a garbage perspective I would be more frightened of a sponge and soap than paper. A sponge is non-biodegradable in most cases (many are made from plastic: http://www.greenlivingtips.com/articles/51/1/Kitchen-sponges.html). The soap has a number of negative effects in aquatic systems. Paper is easily broken down in the environment and can easily be composted. So it again is an issue of what question you ask"

Matt singles out the issue of value as a determining factor in what is considered waste, and what isn't. It is the value of something that makes us re-use it. (Maybe this is part of what TerraCycle uses as its fundamental philosophy.) The generation of entropy is fundamentally a degradation of value - a loss of useful, organised materials to chaos, the degeneration of many forms of energy to heat. Minimising it tries to retain the inherent value of something for longer. But soap is a one-time use good. Its value is gone after water has been added to it, and the suds are on your skin. It is then washed away, and you never see that soap again. So it seems like I have not been accounting for an important item in my waste budget - soap.
