Multi-Level Marmoting

I love those fun little internet games. Like when you take your first pet's name and the street you grew up on, and it's your stripper name. I'm Duffy Buchanan--kind of a working man's stripper, I think. Good thing we didn't have a daughter in 1990. She'd have had to work the pole as Larry Twenty-Ninth.

Got a new one for you: take your first name, your favorite vegetable, and your favorite mammal, and you've got your Internet Huckster name. Wouldn't you buy something from Murr Yam Marmot? No? How about David Avocado Wolfe?

He's doing quite well, thank you, peddling horseshit plus marketing to willing marks. He says chemtrails are real. He hawks apricot pits for tumors because of a compound in them that might fight cancer if it didn't dump cyanide in your system first. He claims academic credentials that don't exist. He's a raw-food proponent but first came on my radar as a promoter of anti-vaccine memes. Because that's what we need now.

Gotta state up front, I come from a rah-rah vaccine family. I was swept into the doctor's office a few seconds after the Salk vaccine came out; I was two, so I don't remember it, but it wouldn't surprise me if Dad camped outside the building to be first in line. I do remember the later sugar-cube vaccine and the time I asked "What is polio?" and my sister Margaret burst into tears of joy because I didn't know. Polio ruined her health from age six on and she finally died of it ten years ago. Polio was eradicated in the United States by 1979. It's possible it will be eradicated worldwide soon.

Want to freak out some kid crying over an injection? Show 'em your smallpox vaccination scar. That's a doozy. If you're younger than 45 you don't have one. We spanked that disease, we did. My smallpox scar looks a lot like the scar from a huge chicken pox blister on my ankle. I didn't feel sick with chicken pox, just itchy, and I went to camp with it and promptly infected the whole place. Did worse with measles, second time around: I still sometimes get the nightmare I had when my fever was up around two thousand. I don't remember the mumps. I was a month old.

Well, anyway, the first time I saw an anti-vax meme I didn't trust it. Poor spelling, of course, and oh my! Photos of pathetically sick children! Babies hooked up to tubes! Were these children adversely affected by vaccines? Snopes smacked that down in seconds. Turns out it's pretty easy to come up with pictures of sick children.

I like my science the old-fashioned way. Design studies to prove or disprove a hypothesis. Crunch epidemiological data. Publish in peer-reviewed journals where your results can be challenged or replicated by other educated people in your field.

But Science can't be trusted, you see. Big Pharma wants babies to be vaccinated against everything because they're raking in the bucks. Ah, no. In fact vaccines do keep people from getting nice and sick, and they are dramatically less profitable to Big Pharma than other drugs. One reason is the good old government buys most of it and has negotiated the price way down. (It could do that for almost any drug or procedure if we didn't have a health care system run by insurance companies, but that's another story.)

Yes, precisely because scientists have long since discredited the supposed link between vaccination and autism, this proves science cannot be trusted. You can take David Avocado "Mushrooms Come From Outer Space" Wolfe's claims to the bank, but feel free to ignore the scientists, who are clearly just out for money. And while you're visiting his site, go ahead and shell out $297 for the Zapper, which "delivers positive and negative offset square wave electromagnetic waveforms throughout the body."

We can't get enough of conspiracy theories. They make our brains light up. In conspiracy-world, a study linking vaccines to autism is not withdrawn because it was fraudulent, but because it was repressed. It's good to be skeptical. But don't forget to apply your skepticism to the memes you're helping go viral, too. Because critical thinking is the only vaccine for that virus.

By the way, Donald Trump is also an out and proud anti-vaxxer, too, but that doesn't mean the position has no merit. Wait a minute, it pretty much does.

And there's this, too. There are a lot of reasons people might create an anti-vax meme and promote it. They might have something to sell. But they might be Russian trolls, too. Not only are they apparently active in trying to undermine public health here, but they are interested in creating as much confusion and division in our population as possible--about anything. And even more, they are interested in stoking distrust in our institutions, especially government and the press and science. The less confidence we have in those, the more easily we can be controlled.

Doctors don't care about your baby. Global warming is a hoax. Taxes are theft. All politicians are the same, so why bother voting?

Petunia Sphincters

We were just treated to a rare celestial event here. It had been predicted, and although the details of how such a thing comes about are well known to science, the casual observer could be forgiven for succumbing to awe. We'd heard about the phenomenon, of course. But until you see it for yourself, it's easy to dismiss. Nevertheless, sure enough, right on cue, the skies began to darken, and we all looked up in joy and wonder.

Yes. Water was coming right out of the sky! Just a little at first, bearing its fine mineral smell, the fragrance Life dabs behind its ears. And then a little more. By morning there was visible wetness all over everything. According to official records, this used to happen all the time. But fifty-seven consecutive days of unrelenting brightness has a way of frying the memory tank.

In fact, those same records show that sky water is a frequent visitor in these parts, to the point where people get impatient with it, and wonder if it will ever pack up all its crap and leave, but all that sounds like fake news now. Every day for the last two months, that searing ball of inevitability has barreled across the sky unchallenged, spreading mandatory cheer into the darkest crevices, more cheer than is good for us.

But Sunday it rained. Lord do love a duck. Snails are racing! Ants are excavating! Leaves are putting on weight!

Which, naturally, puts me in mind of stomata.

Stomata, or stoma pores, are my Spark Science Fact. You birders are familiar with the term "spark bird"--that would be the bird whose sheer stunninghood first sparked their interest in seeing even more birds, and consigned them to a life of nerdy clothing and gear and dangerous driving habits. My spark bird was the Western Tanager. I'd presumed that 90% of birds were indistinct and brownish, and then my brother put a Western Tanager into his binoculars for me and made me look, and that was that. WHEN, thought I, did they start making THOSE? What else might be out there?

My spark science fact also changed everything. I was in tenth grade Biology, a required class that I had been dreading since first grade, when I first heard I'd be compelled to slice up a live frog some day. I hadn't heard of menstruation yet so this was the biggest horror I thought I'd ever have to face. But there I was in Biology class and Mr. Kosek was teaching us about stoma pores. Which was one of the coolest things I'd ever heard of.

I vaguely understood that plants "breathe," but I'd never given any thought to a mechanism. This was normal for me. For instance, not knowing anything about construction, I thought walls were impenetrable, until Amy Cook accidentally sent her butt through one while roughhousing at a slumber party, and there it all was, the whole story, gypsum dust and drywall and a peeved parent. Similarly, I knew plants respired, but I didn't even think to wonder how.

Stomata are awesome. Consider a leaf. It is made up of legions of cells. But some cells are specialized: the paired guard cells of the pores. Stomata are the plant's means of facilitating gas exchange. That's right: they are sphincters. Stoma pores close up when water is scarce, and open when there's plenty. But here's how: they consist of two fairly large cells shaped like kidney beans, lying side by side in such a fashion that the concave portions meet up and, together, form a hole. Or, if you prefer to see it that way (and many do), they are like a set of matched buttocks, at rest. The portions of the two buttocks that form the hole are thicker and less elastic than the surrounding portions, like a constriction in a balloon, so that when the cells plump up with absorbed water, they bend toward each other and the hole becomes larger. At this point, you may prefer (and many do) to abandon the "buttocks" visualization and go back to the kidney beans. The point is, when there is enough water in the plant, the water can escape through the hole, and when water is scarce, the buttock beans go slack and the hole shuts down, and the plant retains its water. Nothing could be simpler, or more ingenious.

We never sliced up a live frog. There was an earthworm and there was a pickled piglet. There was so, so much more. Science class was the hypodermic syringe of joy, and I was ready for an injection. I even ended up with a degree in Biology. It is a wonder in itself.

Because I thought I would be a writer.

The Final Days Are Awesome

Science marching on
It's amazing how much stuff we know! In my lifetime alone--and do not be fooled by appearances, I am but an eight-year-old in a wrinkle suit--we learned that the continents are moving around. I was still in high school.

And it was barely forty years ago that I first read that our worst pollution problem might be carbon dioxide. This was startling. We'd been assuming all along that the dirty smudgy sorts of pollution were the big problems, and if we could keep the black crap from spewing out of our smokestacks, and if we picked up trash on the roadways, and saved the whales, we'd be in pretty good shape. Carbon dioxide was not on our radar.

We certainly wanted the whales saved because they are intelligent and majestic and worthy. But it's only been a few years since we learned how essential they are to the ocean ecosystem, because they forage in the deep where the nitrogen is and come up for air and poop it out as the surface, which jump-starts the whole food chain. No whale poop, no phytoplankton. Who knew? Now we know. Amazing.

Science zigs and zags but marches on, occasionally getting things wrong, and correcting them later. This is exactly as it should be. You looking for certainty, religion is your game.

I'm not sure how we got here, as amazing as our knowledge is, but now most of us are not only science-illiterate, but we don't even understand how science works. Otherwise you'd never get so many people to actually believe that 99% of the world's climate scientists are pulling our legs about global warming. What they are doing, of course, is collecting data from all over, and developing computer models using the data, and testing hypotheses, and publishing their results, which are then reviewed by their peers, who are--or should be--their stoutest critics.

Instead, a lot of people have been persuaded that they are sitting around their little labs pulling in grant money and plotting to manipulate their results so as to bring down the entire world economy that is run on oil. Ha ha! Why would they do that? I don't know. Because people made fun of them in school and now they're secretly conspiring to get everybody back? Who do they think they are? Bunch of smartypants in unattractive lab coats who think they're better than everybody. Same people who told us coffee would kills us, and then changed their minds a month later. They're scam artists.

People didn't used to reflexively dismiss the most educated among us, but now they do. Some corporate shills realized they could make bank on our insecurities to create doubt in the minds of the people. It was a calculated and deliberate effort, and now here we are, in quite a pickle, without the political will to save ourselves.

Most of us are not accustomed to looking beyond the narrow slots of our own lifetimes. Until very recently, people sought out caves for shelter and socked away fat and berries for the winter, as their ancestors had done for hundreds of thousands of years. But somehow, now, most of us think it is completely normal that even though we get winded running for the bus, we can walk into a metal tube in California and be in New York City in six hours. We think it's so normal, in fact, that we bitch about it if we spend an extra hour on the tarmac.

We simply do not comprehend what a very special time we're living in. This unprecedented luxury feels like our birthright. We don't want it taken away. And we can't imagine why anyone would want to take it away.

Right now a group of people are making a stand against a pipeline. They want to protect their water; some of them want to protect sacred sites. It's just one pipeline segment, but they have a lot of support from people like me who witness their bravery and recognize their stand as being the spearpoint in the fight against catastrophic climate change. When we make our case, we're mocked. I've never seen anyone protest the oil truck coming to their house in the middle of the winter, writes one wag on the internet. We're hypocrites, in other words.

If this is how you see us, this message is for you:

Aw hell no, Sugar! We're like everyone else. We love this stuff. I can get in my car and expend four calories with my right foot and be walking on the beach in an hour? Awesome. I can flick my index finger and make my house cold enough I need a sweater in July? Outstanding. I can drive to the store in January and buy fresh salad greens from a thousand miles away and then just toss the plastic box in the garbage? Baby, oh baby! We are living better than kings and queens, every one of us, even if we don't fully appreciate it, and all because we're digging up a finite fossil swampland and burning it up as fast as we possibly can, right now. We haven't been doing it for long, and we won't be able to do it for much longer. But right now? We get to have all this swag.

And there ain't an environmentalist with a beating heart that wouldn't want to keep that up if it were possible. And if it weren't going to seal our doom.

Look at us! We never even had the first clue about the whale poop and the plankton, but we're willing to allow half the world's species to go extinct on our watch, and cross our fingers it all works out. Maybe we still feel safe; maybe we live on high ground, and still have air conditioning. Meanwhile, we won't even take in a Syrian victim of terrorism in case she's a terrorist; but in a few years, entire populations are going to be on the move. Climate refugees, trying to survive. If we're not interested in making room, and sharing our stuff, we could start by not assuming scientists are frauds.
