Thanksgiving

The following is a re-edited version of my Thanksgiving post from last year. It’s still timely.

“It’s that time of the year again,” warns a cynical-sounding blogger, “when warmists try to link Thanksgiving and climate change.”

Nice rhetorical trick, isn’t it? The thing is that of course anything in human life can be linked to climate change because everything we experience either depends on climate in some way or influences it. Most writers seem to cluster around one of two main narratives: Thanksgiving as an opportunity to talk about climate change and agriculture (as in turkeys could get more expensive as feed prices rise because of recurrent drought); and Thanksgiving as an opportunity to talk about communication (as in what you have to do with your climate-skeptic relatives). These are excellent points and I’m not going to try to make them all over again.

Instead, I want to talk about gratitude. I want to talk about abundance.

Have you ever thought it strange that we give thanks by eating a lot? If anything, American Thanksgiving sometimes seems more a celebration of greed and gluttony, with a perfunctory discussion of life’s blessings thrown in among the other topics at the dinner time. And yet, it is precisely abundance that serves to remind us of what we have to be grateful for. Thanksgiving provides the illusion of infinite, inexhaustible resources because there is more food on the table than the assembled eaters can consume. It is that illusion we use to evoke and celebrate our abundance.

And it it is an illusion. There is no such thing as an infinite resource; use enough of anything for long enough and eventually you will run out. Even “renewable” resources are only sustainable if you use them slowly enough that they can replenish themselves. We know from sad experience that it is indeed possible to run completely out of precious things that once seemed all but limitless. Passenger pigeons, for example. And in fact we are running out of pretty much everything we need for life and everything we need to give life beauty and meaning. Often, the depletion is hidden by ever more efficient usage that keeps yields high even as the resource itself runs out. We see this with fisheries, with soil health, with oil…. It’s not that we don’t have enough of what we need yet (hunger is usually a distribution  problem, not a supply problem; there are more overweight than underweight humans right now). The problem is that we are using so much that the world is warming under the pressure.

See how big we are, relative to the rest of the biosphere? Humans already use more than the entire ecological product of the entire planet. That is possible because we are, in effect, spending planetary capital, reducing Earth’s total richness a little more every year.

I’m not trying to be gloomy for the sake of gloominess, I’m talking about the physics of the environmental crisis, the details of how the planet works. I’ve gone into detail on this before, but the basic idea is that the planet has an energy budget and that when part of the planet (e.g., us) exceeds this budget, the planet as a whole destabilizes. The biosphere actually shrinks and loses energy and diversity. One way to describe global warming and all its awful permutations is as a complex system being pushed into an entropic state.

We got into this mess by treating the entire planet as the thing a Thanksgiving feast is meant to simulate; literally endless bounty. And because we did that, our descendants will have a smaller, leaner table to set than our ancestors did–and the more we use now, the leaner that future table will get.

Does that mean we shouldn’t celebrate Thanksgiving? Of course not.

Real, literal feasts are never actually about unlimited consumption. We know perfectly well that the Thanksgiving table may groan, but it’s not actually infinite. It just feels that way, and it is that feeling that is important. The illusion of physical abundance is a needed reminder of the truth of spiritual abundance–which is the actual point of the holiday, the thing we’re supposed to be celebrating on a certain Thursday in November.

The psychological power of the illusion of abundance does not depend on vast resources, something families of limited means understand well. By saving up and looking for deals and cooking skillfully, it is possible to produce a sumptuous feast that feels abundant and actually sticks within a fairly modest budget. The spiritual value is accomplished.

That’s what we have to do as a species. We have to find a way to live within our ecological means–the first step is to get off fossil fuel–and yet work with what we have so skillfully that what we have feels like more than enough. By staying within a budget we can stop worrying about running out, which is true, if paradoxical, abundance. Then the planet will have a chance to heal. The biosphere will grow again. And it is possible, just possible, that our descendants will live to see a more bountiful feast than we will.

And that will truly be something to be thankful for.
