This Land Is Not Our Land


This is the title in one of the songs of the musical Nanyehi, written by Becky Hobbs and Nick Sweet. The musical is about the ancestor I share with Becky: Nancy Ward, a.k.a. Nanyehi. If you get a chance, go see this musical (information at the link above).

In this song, Nanyehi’s warrior cousin Tsiyu Gansini and his warriors has encountered a white farmer on Cherokee land. The farmer showed them the deed which the South Carolina legislature had given him, proving his land ownership. Tsiyu Gansini told him that it was Cherokee land and the legislature had no right to sell it. As a matter of fact, even the Cherokees did not own the land. Nobody can own the land. It belongs to the Great Spirit, or to God, or to all the species, not to any individual human. “This land is not our land, it’s only ours to use, it don’t belong to me, it don’t belong to you.” This is the original Cherokee view (and that of many other tribes), and remained so until private land ownership was forced upon the tribes (in the case of the Cherokees, by the Dawes enrollment of 1904).



For years, I have opened the class session about ecology, for my general biology students, with this song. It expresses perfectly what I want them to understand about ecology. After going over some basic concepts of ecology, such as the Ten Percent Law and biological magnification, I then show them a slide that summarizes ecosystem services, especially as it relates to plants. All the things that plants do for us for free! A forest is worth much more alive than dead. I wrote a whole book about this years ago: “Green Planet.


How do I draw all of this together? If you look at the Earth, or any part of it, from the private ownership viewpoint, then a forest is worth more dead than alive. You, the owner, can get money for the timber. But to the world as a whole, it is worth more alive than dead. A living forest creates oxygen, uses up carbon dioxide, holds down the soil, lets rain penetrate into the soil, etc. But notice that these are all benefits not just to you, the owner, but to everyone else. If you forego the profits from the timber, most of the benefits go to other people and you cannot make a profit on it. Other people, who do not pay you, get to breathe the oxygen.

That is, to see the benefits of ecosystem services, you have to take the original tribal view rather than the modern capitalist view. The rich people who own most of the land do not care if the land’s ability to keep us alive is destroyed, so long as they can live someplace where someone else’s plants are producing oxygen and preventing floods.

Nobody in my classes has ever complained about my attack on unlimited private capitalism. I think it is because I introduced it in the context of tribal world views (in Oklahoma, many of my students are part or full Native American) and through the vehicle of Becky’s music.

What Is a Forest Worth? More Requiem for Nature


Whenever I write about somebody else’s book, I fear that I might have represented it. I sent the link to the previous essay to John Terborgh, author of Requiem for Nature. He responded that my summary was essentially correct. He added, reprinted with his permission:

The world has moved on in a way that is predictable but not conducive to protecting nature. I say predictable, because the fundamental economic goal of nearly every country on the planet is to maximize economic growth. With this as the background to nearly all important policy decisions, nature doesn't have a chance. It is the empty chair at the conference table.

Perhaps the most memorable lecture I heard in college was one delivered by my Freshman biology professor in which he laid out in vivid terms the consequences of unchecked population growth. That, my friend, was in 1955. Here we are, 64 years down the road, and putting the brakes on the human population is still a topic that can't be mentioned in polite company - much less in open political debate.”

One issue in my essay remains unresolved. Terborgh said that a tropical forest is worth more dead than alive. In my book Green Planet, I said that a forest is worth more alive than dead. Which of us is correct? I realized that it depends on who is making the decision. For people collectively, as in a community or a world, a forest is worth more alive. But for individuals or corporations whose only goal is short-term profit, a forest is worth more when it is dead. Alas, evolution (biological or cultural) rewards individual, not collective, benefits. Collective benefits accrue only when they provide a direct and immediate benefit to individuals. For example, altruism within a group of animals offers immediate benefits to most, even if not all, of the individual animals in the group.

In the first photo, I am leaning against a rainforest tree (I have no idea which species, there are so many!) in 1989; in the second, I saw an area in which the rainforest had been hacked away, exposing soil to erosion.



Meanwhile, all I can do is to teach and to write. I continue to do these things even if they are likely to have little effect on the course of the future. As John added at the end of his message, “Carry on with your efforts to prod students into thinking out of the box. It's the only way we'll get out of this mess.”
