A Problem of Scale
Sharon July 8th, 2009
It isn’t just artists who sometimes have trouble with perspective – all of us do. Consider our tendency, for example, when speaking of history to pick and choose the historical periods we consider relevant. Thus, for example, proponents of the traditional family emphasize the 1950s and ignore the 1940s, although there’s certainly a case to be made that American history has enough wartimes, which inevitably upend gender roles, that the periods of stability in between were not normative. Or consider narratives of, say, European goodness and American awfulness, which are moderately credible if history begins in 1980, say and not at all credible if it begins in 1930. Or whatever. All of us generally prefer the long view to the short one, the small historical model in the short term to the big sweep of history and all its variations.
Bigness is one of those things that is remarkably hard to estimate – I can show my children a picture of a New York City Building, a Redwood Tree, an elephant and a child to give a sense of the size of a Redwood – but until you have craned your neck and looked up and up and up and up some more at a tree that goes on forever, perspective remains a flat thing, rather like the medieval painting from exemplum, rather than from life – thus we make the images in our heads of things, and thus we are astonished by the vitality of reality.
This problem of flattened mental visions of vast things confronts us everywhere, most notably as we attempt to navigate our collective ecological crisis. The sheer vastness of the scale of our problems is one most of us have no ability to come to grips with – indeed, are never asked to come to grips with. We are shown our problems in flat terms, ones that many of us do not fully understand – that is, it is hard to imagine the hugeness of a Diplodocus over an elephant, particularly if one has never actually seen an elephant up close, never been close enough to one to see how enormous it really is – and then to imagine 50 of them…one’s mind tends to look and say “ok, that’s big, and the other thing is really big.”
Consider the problem of soil – I’ve heard some people say it isn’t a problem at all, after all, soil can be built. And this is absolutely true. One simple way to do so would be to buy some straw or old hay and place 6 bales together, making a bed. Fill this bed with woodchips, some more straw, some grass clippings, some brush and leaves, animal or composted humanure, a few shovelfulls of dirt from a forest floor, water it, perhaps pee on it, and go about your business. In a few months, the fungi and bacteria will have feasted upon the organic matter, and produced a lesser amount of glorious growing medium, which carefully nurtured and sustained will bring forth food in perpetuity.
It is even possible to imagine a concerted national effort to do this – national “build a garden bed day” in which almost all Americans not needed elsewhere did this. There would be stiff competition for brush and straw, of course, but it is possible to imagine that at the end of the season, 100 million new 4×10 garden beds would be constructed. Done in fall, that’s 400, 000,000 new square feet of growing space, more than 300,000 new acres of land available for growing.
Of course, 300,000 acres is no more than a drop in the bucket, in terms of total national acreage needed (don’t get me wrong, it would still be a good idea!). And therein lies the problem of course – there simply isn’t enough straw or forest soil, grass clippings or manure to fully restore our topsoil for a really, really long time. There aren’t enough animal manures either – which is why we’re going to have to come to terms with the question of humanure, and probably right quick now.
Or consider the solar panel – it seems like such a good idea to simply power everyone’s house with solar, whether individual panels or vast plantations in the desert. We keep being told we use only a tiny percentage of the solar energy that pours forth upon the earth. Ignoring the fact that it is actually kind of horrifying to imagine human beings using all the energy the sun pours forth
, there’s the fact that those vast plantations of solar panels must be built in the Gobi and California deserts, where people do not live. They cover vast areas, and aren’t near much – in order to build them, one must first build housing and shelter for the people who build them, and run water there. Then one must truck in concrete, with its enormous ecological footprint, and again, run water for the process of installation. Meanwhile, at a distant factory one must manufacture not thousands but millions of solar cells, from trace minerals that must be mined.
The ecological cost of all of this is high – I’ve pointed out repeatedly that in fact, we may actually cross our climate threshold by building out resources to prevent further climate change, an irony I don’t find at all appealing. All the energy must be fronted – that is, all of the renewables require a front investment in fossil fuels, that are burned and will never come back. Moreover, they require an upfront investment in money – which means people rich enough to tie up their money for a long time awaiting returns.
And because solar panels are far less energy dense, with a lower EROEI than most fossil fuels, in order to replace 1 barrel of oil, we have to build 5 solar cells – that is, we aren’t replacing the billions of barrels of oil 1-for-1, but 5-for-1 which drives up the scale even further. Most of us are no longer actually holding an image in our head of what that means in miles of panel, tons of concrete, tonnes of carbon dioxide, mining equipment or anything else. We’re back at looking at how big the dinosaur was – big vs. really big. And because we know we’ve already done some really big things – the moon launch, the nuclear program, we don’t even bother calculating how big – if we could do one big thing, we must, by logic, be able to do another.
We have in our own way as much problem with perspective as artists do – there’s as much to say, although I won’t say it today, about our problem with perceiving small things, except to quote Gaston Bachelard, from _The Poetics of Space_ in saying “Distance, too, creatues miniatures at all points on the horizon, and the dreamer, faced with these spectacles of distant nature, picks out these miniatures as so many nexts of solitude in which he dreams of living” – and observe that it isn’t just that we decline to see the vastness of our problems, we are attracted to them, miniaturized by distance and unfamiliarity. Thus the electric car looks adorable, endearing, a place to keep the dream of private transport alive, as long as we do not look to close at the realities of our dreams.
Perspective is not easy, and it isn’t a problem that is fully soluble – the long view leaves things out as much as the short one, and vice versa. No view is perfect – looking up at the Redwood, the Cathedral, the elephant, one is prone to overestimate, to factor in the direct experience of shock and overstate things. And yet, knowledge by authority, analogy and example were insufficient – there’s a reason that Renaissance art, with its emphasis on focused perspective based on observation is a stunning leap over the best of medieval art – not because the Renaissance painter was the first to see, but because the Renaissance painter insisted that if you could not get all the perspective needed, you could at least insist on grounding authority in experience and reality.
Most of us need to get up close and personal with things like numbers and other evidence of scale – and those of us who write about this stuff need to work harder at illustrating the problems of scale – because we face an audience that does not understand them – they think they are looking at two large creatures, one big, one bigger – they do not realize that the difference between technological and real solutions are the difference between absent dinosaurs of surpassing hugeness and ordinary, just really big elephants.
