in cities, no experience is directly between us and the planet. Virtually all experience is mediated in some way. Concrete covers whatever would grow from the ground. Buildings block the natural vistas. The water we drink comes from a faucet, not from a stream or the sky. All foliage has been confined by human considerations and redesigned according to human tastes. There are no wild animals, there are no rocky terrains, there is no cycle of bloom and decline. There is not even night and day. No food grows anywhere.
Most of us give little importance to this change in human experience of the world, if we notice it at all. We are so surrounded by a reconstructed world that it is difficult to grasp how astonishingly different it is from the world of only one hundred years ago, and that it bears virtually no resemblance to the world in which human beings lived for four million years before that. That this might affect the way we think, including our understanding of how our lives are connected to any nonhuman system, is rarely considered.
In fact, most of us assume that human understanding is now more thorough than before, that we know more than we ever did. This is because we have such faith in our rational, intellectual processes and the institutions we have created that we fail to observe their limits.
I have heard small children ask whether apples and oranges grow in stores. “Of course not,” we tell them. “Fruit grows from the ground somewhere out in the countryside, and then it’s put into trucks and brought to the stores.”
But is this true? Have you seen that? Do you have a sense that what you are eating was once alive, growing on its own?
We learn in schools that fruit grows from the ground. We see pictures of fruit growing. But when we live in cities, confined to the walls and floors of our concrete environments, we don’t actually see the slow process of a blossom appearing on a tree, then becoming a bud that grows into an apple. We learn this, but we can’t really “know” what it means, or that a whole cycle is operating: sky to ground to root through tree to bud ripening into fruit that we can eat. Nor do we see particular value in this knowledge. It remains an idea to us, an abstraction that is difficult to integrate into our consciousness without direct experience of the process. Therefore we don’t develop a feeling about it, a caring. In the end how can our children or we really grasp that fruit growing from trees has anything to do with humans growing from eating the fruit?
We have learned that water does not really originate in the pipes where we get it. We are educated to understand that it comes from sky (we have seen that, it is true!), lands in some faraway mountains, flows into rivers, which flow into little reservoirs, and then somehow it all goes through pipes into the sinks in our homes and then back out to—where? The ocean.
We learn there is something called evaporation that takes the water we don’t need up to the sky. But is this true? Is there a pattern to it? How does it collect in the sky? Is it okay to rearrange the cycle with cloud seeding? Is it okay to collect the water in dams? Does anyone else need water? Do plants drink it? How do they get it? Does water go into the ground? In cities it rolls around on concrete and then pours into sewers. Since we are unable to observe most of the cycle, we learn about it in knowledge museums: schools, textbooks. We study to know. What we know is what we have studied. We know what the books say. What the books say is what the authors of the books learned from “experts” who, from time to time, turn out to be wrong.
Everyone knows about night and day. Half the time it’s dark, half the time it’s light.
However, it doesn’t work that way in our homes or outside in the streets. There is always light, and it is always the same, controlled by an automatic switch downtown. The stars are obscured by the city glow. The moon is
