An interesting and important article about a researcher gathering data that seem to show that although more carbon in the air means plants grow faster, the result is plants with more sugar but less protein, minerals, vitamins, and other nutrients:
the protein content of goldenrod pollen has declined by a third since the industrial revolution—and the change closely tracks with the rise in CO2.
From the IMF blog, a great chart showing the rate at which motor vehicles took over from horses early in the 20th century. Putting current motor-vehicle and electric-car use on the same graph makes a pretty good visual case that we might be as little as 15 years from the cross-over point where half the vehicles on the road are electric.
Greater affordability of electric vehicles will likely steer us away from our current sources of energy for transportation, and toward more environmentally friendly technology. And that can happen sooner than you think.
This great article in Al Jazeera America hits a whole bunch of my interests: healthy eating, decolonization, sustainability, preserving culture: Eating indigenously changes diets and lives of Native Americans. Basically, more than one group of researchers who are also Native Americans have decided to look into seeing if they could eat the way their ancestors ate.
Reinhardt, a professor in the Native American Studies program, was helping to serve up fry bread, Indian tacos and other offerings at the annual First Nations Food Taster, a fund-raising event for the Native American Student Association, when he had an epiphany: “Would my ancestors even recognize this as food?”
If you, like me, are a fan of Michael Pollan’s work, there’s a lot here to find interesting. There is considerable overlap with the “paleo” diet (although the researchers set their time threshold at 1602, rather than the dawn of agriculture) and with the locavore movement (with different locales for different Native American researchers).
The article touches on all sorts of question: Do we even know what they ate? Are the plants and animals still available? Is such a diet healthier than a modern Western diet?
Interesting as the food issues are, the issues having to do with decolonization are at least as interesting, as are the issues having to do with sustainability.
The News Gazette had an article yesterday saying that the Champaign City Council has agreed to “schedule a study session” on the topic of legalizing backyard chickens.
Tom Bruno, who was the guy who offered me some encouragement when I inquired earlier seems ready to support the idea. Other members of the council sounded more ambivalent. The comments on the News Gazette article are decidedly mixed as well. (The people who object not because they think the chickens would actually cause any sort of problem, but because they’re afraid that it would make the area seem too “redneck” surprise me.)
So, it’s by no means a sure thing. Time to get organized.
One utterly predictable consequence of climate change is that the price of northern farmland will rise as growing regions shift north.
Tobias Buckell yesterday shared a report that just this sort of price shift is now occurring—interesting to me because this result is not merely predictable: I predicted it my own self, way back when I was in high school.
Global warming was still pretty speculative then (in the 1970s), but people were already talking about the greenhouse effect and trying to figure what the result would be. At the time, I was mainly thinking about the geopolitical implications of shifting the growing regions north—how things would change if Canada and the (then) Soviet Union were suddenly way more productive of food, while places like the United States, China, and France suddenly less so.
What I discovered, though, was that those northern regions aren’t nearly as fertile as places like Illinois, where 8,000 years of tall grass prairie left an incredibly thick layer of rich soil.
No matter how perfect the climate is, Saskatchewan is not going to produce the bushels per acre of Illinois or Kansas. Their soil is not only less fertile, it’s also much more fragile than the soil of the tall grass prairies. The fertile layer isn’t as deep, so the land must be plowed with greater care, and it will in any case be more quickly depleted.
I’m sure there’s a lot more and better data available now than there was back then, but I doubt if it changes the fundamentals. Shifting growing regions means winners and losers, but it also means less total food production.
We usually buy our peanut butter from a local health food store that grinds it fresh. The owner comes out from behind the counter, grabs a 1-pound package of peanuts from the cooler, and then takes it back behind the counter and grinds it while you wait. (I think you’re supposed to get the package yourself and bring it to her, but I didn’t know that. Jackie usually does the shopping there.)
Sadly, we just used up our package of freshly ground unsalted unsweetened peanut butter, and for lunch today had to make do with our backup supply—some national brand peanut butter. We keep it on hand for two reasons. It’s less runny than good peanut butter, which is nice when we’re making peanut butter sandwiches to take to a lunchtime lecture at OLLI (or any similar brown-bag event) and want a minimally messy lunch. And it stores well.
It’s not as healthy. It’s salted and sweetened. Worse, some of the healthy peanut oil has been replaced with some less runny oil. (Although they now use less hydrogenated vegetable oil than they used when I was a kid.) But you know what? The commercial stuff tastes good even so.
Still, we’ll get some more freshly ground peanut butter first chance we get.
There’s a letter to the editor in today’s News-Gazette from Clarence Surma advocating for legalizing backyard chickens in Champaign.
In addition, he’s announcing a public meeting on the topic at the Champaign County Farm Bureau on June 2nd at 6:30 PM.
I would have liked to provide some useful links, but the News-Gazette doesn’t seem to have letters to the editor available on-line, Clarence Surma doesn’t seem to have any web presence at all, and I couldn’t find any mention of the meeting on the Farm Bureau’s website. So, not much to link to. I’ve got email in to the Farm Bureau asking for details, and will update here I find learn any more.
If anybody has any links, I hope they’ll share in the comments or by email to me.
People are bad at comparing risks, and people like to point this out by making comparisons to risks that people tolerate on a daily basis. For example, pointing out that many more people die in car accidents than are killed by terrorists, or pointing out that providing electricity by burning coal kills and injures more people than providing electricity by fissioning uranium.
At one level, I find these arguments compelling. I find it preposterous that we spend so much money on homeland security. That money would be much better spent (in terms of lives saved per dollar) on traffic safety, or probably a lot of other things. I gather, based on the fact that people keep pointing this out without producing any visible change in funding priorities, that most people don’t find this a compelling argument.
I’ve always wondered about that, and perhaps I’ve figured out why in the “coal versus nuclear” argument, which I don’t find compelling.
Plenty of people die to provide us with power from coal. Miners die from accidents. People die in road accidents moving coal from the mine to the power plant. Workers die in ordinary industrial accidents at power plants. People die from respiratory problems caused by or exacerbated by pollution from burning coal. People die in severe weather—which is becoming more common, probably because of global warming.
Except for that last, this is our baseline status. We know the costs and risks, and we accept them. Some people work to improve things—better mine safety, better level crossings for trains, lower emissions from coal burning—but the baseline is accepted. Importantly, an individual can do a lot to reduce his or her risk, such as by not making a career in coal mining, by exercising due care at rail crossings, and by living some place with clean air (and not smoking).
With nuclear power, things are different. The baseline status is safer. Deaths in uranium mining are very small, because the volume of uranium ore needed is so small compared to the volume of coal. Deaths from industrial accidents are small, because the number of workers is small (and, perhaps, because some additional attention is paid to safety at a nuclear plant for reasons having to do with greater regulation and particular concerns about public perceptions of safety). Deaths caused by the release of radiation are very, very small, because we go to vast effort and expense to avoid them.
But although the baseline status is relatively safe, the contingent risks are huge. The problems that led to the catastrophe we’re seeing now at the Fukushima Daiichi plants are replicated all over the world. It’s not just plants built on fault lines and plants built places where tsunamis can occur. It’s things like redundant safety systems that aren’t really redundant. Most especially, it’s committing to providing active safety over a period that’s much longer than human institutions reliably persist.
On the former issue, I have an oddly relevant memory. As a boy I attended public hearings in Kalamazoo on the licensing of the nuclear power plant at Palisades. At one hearing, a lawyer opposing licensing pointed out that a line carrying backup power for the plant ran through the same conduit as a line carrying the regular power. In some clever showmanship, he snapped a pencil in two to illustrate the fact that this produced a common point of failure. Learning that the backup generators at Fukushima were in basements where they would be lost in a tsunami produced an odd echo of that memory.
The latter issue is really more to the point. We are relying on corporations to actively manage the safety of these plants and the spent fuel—corporations that will cease to exist if the cost of this management burden ever grows to the point that it consumes the corporation’s profits.
I think the degree to which these safety issues needed to be actively managed has surprised a lot of people. I’ve many times heard people suggest that managing nuclear waste was no big deal—just put the stuff in a concrete vault and put a fence around it with signs saying “If you come in here you’ll probably die.” I always knew that was dumb, but I was mostly worried about people deliberately coming in to use the waste to make dirty bombs and the like. I didn’t quite realize to what an extent the spent fuel rods depended on a whole complex system of cooling equipment to keep them from bursting into flame and spreading radioactive smoke and steam wherever the wind blew.
So that, I think, is why we accept coal power and think of nuclear as dangerous. We could give up coal power anytime we, as a society, decided that the cost was too high. If we were willing to cut way back on air conditioning, electric lighting, and all the other things we run with electricity, we could just quit the whole thing. The only dangers left behind would be some moderately dangerous holes in the ground, some toxic heaps of ash, and the pollutants that are already in the air. With nuclear power that’s very much not true. We could give up nuclear power today and we’d be on the hook for decades of active management of the high-level waste and generations of (mostly passive) management of the low-level waste.
I think maybe the issue with risks from terrorism is the same. People know what the trade-offs are for driving. If we, as a society, decided to give up driving, we could cut deaths from road accidents almost to zero. But terrorism isn’t like that. There’s nothing we could give up to prevent terrorism, and the contingent risks are huge. An endless stream of terrorist acts that killed tens, hundreds, or thousands of people seems very different from the many other activities that we engage in that cost tens, hundreds, or thousands of lives.
It’s a bummer about nuclear power, though. It would be cool if a network of high-speed electric trains could provide transportation in a post-peak oil world, and I’d begun to think it might be a reasonable alternative. A mere twenty-five years with no major nuclear accidents was enough to make nuclear power start seeming pretty safe again. This is a good reminder that it really isn’t—and that we need to think carefully about the difference between accepting risks for ourselves now, and accepting risks for everyone stretching off into the future.
[Update 2011-03-23: There’s a lot of misinformation about whether very low doses of radiation are harmful. Here’s a paper with a survey of what we actually know about the effects of low doses of ionizing radiation (from the Proceedings of the National Academy of Sciences).]
