Arctic Gender Imbalance

(stream / mp3)

Only girls are being born in a village in Greenland. Host Steve Curwood turns to Lars Otto Reiersen, of the Arctic Monitoring and Assessment Program, to find out what may be behind a growing gender imbalance in babies born around the Arctic Circle. (05:00)

From Toilet to Tap / Ingrid Lobet

(stream / mp3)

Los Angeles recently announced it will begin recycling sewage waters into drinking water using advanced treatment. LA is following the lead of Orange County, CA, which earlier this year opened the most advanced such system in the country. Living on Earth’s Ingrid Lobet reports in this piece. (06:30)

Northwest Dead Zone

(stream / mp3)

There are about 200 oxygen depleted regions, or dead zones, in the world’s oceans. They occur when fertilizers and manure in runoff reach the sea, fueling algae that eats up all the oxygen. But a dead zone off the coast of the Pacific Northwest has scientists looking at a different culprit – climate change. Host Steve Curwood turns to Professor Jack Barth of Oregon State University to learn more about what might be behind the dead zone in the Northwest. (06:00)

Dial-A-Fish / Ashley Ahearn

(stream / mp3)

When you’re in the supermarket or ordering fish at a restaurant, ever have trouble remembering which species has high mercury, which is overfished, and which is the most sustainable? Now, a new text messaging service can tell you everything you need to know, whether one fish, two fish, red fish or blue fish. Living on Earth’s Ashley Ahearn takes her cell phone to a local market to find out how the Fish Phone works. (03:30)

Interpreting History / Jim Williams

African American Park Ranger Shelton Johnson channels Sergeant Alizy Bowman, bringing back a Buffalo Soldier who helped guard Yosemite National Park just after its creation. Producer Jim Williams went to the park and has our profile. (08:30)

Global Weirding

(stream / mp3)

Listeners suggest alternatives for the terms “global warming” and “climate change,” which are both common, but not quite correct. How about human consumption climate disruption? (02:15)

Life As a Locavore

(stream / mp3)

Author Barbara Kingsolver recounts eating locally grown food for a year in the book “Animal, Vegetable, Miracle: A Year of Food Life.” She talks to Steve Curwood about why food has become a public issue, the challenges of finding local food year-round, and how the commitment ultimately changed her family. (09:30)

[THEME]

CURWOOD: From Public Radio International—this is Living on Earth.

[THEME]

I’m Steve Curwood. Waste not, want not: Orange County, California purifies its sewage water and sends it back to the tap. After a ten-year public education campaign, most residents are on board.

HELLEBRAND: …and the school kids come through, and they’re kind of looking for that yuck factor. And by the time they get to the end of the process and they see that the water is so clean - you almost want to drink it!

[LAUGHS]

CURWOOD: Also biologist-turned-best-selling novelist Barbara Kingsolver tells the tale of her family’s commitment to eat mostly local food for an entire year.

KINGSOLVER: As happened over and over again in this project what we found was so much more than what we were looking for. This isn’t a story of deprivation. This is a story of gratitude.

CURWOOD: Barbara Kingsolver and “Animal, Vegetable, Miracle” and more this week on Living on Earth. Stick around!

Arctic Gender Imbalance

[NPR NEWSCAST: Boards of Canada “Zoetrope” from ‘In A Beautiful Place Out in the Country’ (Warp Records – 2000)]

CURWOOD: From the Jennifer and Ted Stanley Studios in Somerville, Massachusetts - this is an encore edition of Living on Earth. I’m Steve Curwood.

In certain villages in northern Greenland something is completely out of whack—only girls are being born. These reports from villages near the U.S. Air Force base in Thule are now being explored by scientists. But studies conducted a few years ago now coming to light show that in other Arctic regions, the sex ratios of babies are also out of kilter. In 2004 the Arctic Monitoring and Assessment Program found a correlation between exposure to PCBs and shifts in the sex ratios of babies born to indigenous mothers living in the northern reaches of Russia. PCBs and other persistent organic chemicals such as pesticides travel from industrial countries up the food chain into the blubber of marine mammals. Lars Otto Reiersen is the executive secretary for the Arctic Monitoring and Assessment Program. His group conducted the study as part of ongoing research on pollution, diet and health in the region.

REIERSEN: The most interesting and surprising result was that we saw a change in the sex ratio that we could correlate to the levels of PCB in the mother's blood. And we saw that if the mother had more than four micrograms per liter in her blood the average was to change two girls per boy in the population that we studied. And that's a quite dramatic change from a normal situation where there are more boys than girls born.

CURWOOD: Now when you say more boys than girls born, how many more boys than girls?

REIERSEN: I think normally—statistically—there is 1.05 or 1.1 boy per girl. That's the normal average.

CURWOOD: In this population though it's 2.0 girls per boy.

REIERSEN: Yeah, when the mothers have these levels of PCB, yeah. And we also saw that the birth came earlier and the weight on the newborn babies that had the highest levels were lower than the normal.

CURWOOD: Tell me about how you went about collecting your data. How did you find your subjects? Who were these people?

REIERSEN: Based on the study we'd done in Greenland and Canada we are focusing mainly on the indigenous people living off the marine food chain because we've seen that these people have the highest levels because of their lifestyle. And we worked together with the indigenous people to collect the samples over a year's period to get enough statistical data. And we have continued after that. The first report was published in 2004 and the new data just confirmed what we saw earlier. So what we're looking into now is to try to understand what is the mechanism behind it.

CURWOOD: Now, looking at your report here I'm just struck by the apparent effects that PCBs have on the sex ratio of children and the way it changes. The chart you have there, I'm looking at page 175. The chart that you have there shows that as you increase exposure to PCBs, at first you get way more boy babies than girl babies. But then as you go higher and you get above four micrograms per liter of blood you get way more girl babies.

REIERSEN: Yes, I can see that. And the scientists do not have any good explanation of why it looks like you have a stimulation at the lower levels and then you get the opposite effect when you go beyond that level. So, what we're doing now is that we're looking into the certain polar arctic to see—do we see any similar effects in Canada or Greenland?

CURWOOD: How might PCBs do this do you think?

REIERSEN: Well, it could be what we call the mimic of the hormones. That early in the pregnancy that some of these pesticides may mimic testosterone or estrogen. That's documented from science. So, that might be what's occurring but that's too early to say for sure what's the mechanism.

CURWOOD: Now, PCBs are concentrated in the arctic and concentrated in marine mammals. But what might this mean for the rest of us around the world who have exposure to PCBs but at a much lower level?

REIERSEN: That's a good question. PCB is all over, it's not only in the Arctic. You have it all over the world in the terrestrial and marine food chain, and in fresh water. So, from laboratory studies we know that PCBs may effect reproduction, may have effects on cancer and immune systems. But I think it's very difficult to document that on the population level. You have to have very detailed studies like the one we did in Chukotka area.

CURWOOD: How have the governments of the Arctic responded to your research?

REIERSEN: Well, they have responded very active. I think you have got the Stockholm Convention in place to a far extent due to the work we have done in the Arctic over the years.

CURWOOD: And the Stockholm Convention is?

REIERSEN: That is an international agreement among countries to reduce the production and use and discharge of persistent organics. I think that is what you need actions to clean up the use of PCB and the old waste sites of PCB and others of these chemicals. That's important actions to be taken.

CURWOOD: Lars Otto Reiersen is the executive secretary for the Arctic Monitoring and Assessment Program. Thank you so much, sir.

REIERSEN: Thank you

From Toilet to Tap

Orange County will soon use purified wastewater to replenish sinking groundwater. (Photo: Orange County Water District)

CURWOOD: Shortages of water in Southern California had officials looking in some unlikely—and perhaps unsavory—places.

[SOUND OF TOILET FLUSHING]

CURWOOD: The squeamish call it ‘toilet to tap.’ The correct term is ‘indirect potable water reuse.’ That’s a mouthful. And recently, 2.3 million people in Orange County California began quenching their thirst with it. Living on Earth’s Ingrid Lobet reports.

LOBET: It's the basic tenet of public health—keep your water and sewer separate. Yet Orange County water and sewage treatment officials have found the closer they work together, the better.

WILDERMUTH: Because of growing population, we knew that we need to put more water in the groundwater basin. And so 10, 13 years ago, we started looking around.

LOBET: That's Ron Wildermuth of the Orange County Water district. In the mid 1990s, his department saw that it was pumping fresh water out of the ground at an unsustainable rate. At the same time, the county sanitation department was looking at building a second concrete pipe to carry its partially-treated sewage out to the ocean.

WILDERMUTH: So you had one water agency needing water. You had a sanitation district that was going to have to build another pipe to dispose of more water. So they came together and said ‘why don't we take that water, purify it, and then you won't have to build the ocean outfall.’

LOBET: It helped the decision along that the cost of electricity to clean wastewater was less than pumping water over the mountains from northern California, and also less than getting the salt out of seawater.

[SOUND OF FLOWING WATER]

HELLEBRAND: This water now is what will be sent over to the water districts. So we're at the end of the water process.

LOBET: Now, more than a decade later, Ingrid Hellebrand of the Orange County Sanitation District points with pride at her finished product—strained, settled, aerated and skimmed into a goldish but clear liquid. Hellebrand calls the stuff she deals with everyday ‘water.’ Does she really think of it as water?

HELLEBRAND: Yeah, it’s, it’s water!

LOBET: Well, 99.9 percent water. There is .1 percent of something else.

HELLEBRAND: When you flush the toilet, when you brush your teeth, the water just goes away. And nobody really thinks about where away is, but that’s where I work—where ‘away’ is. And the school kids come through, and they're kind of looking for that yuck factor. And by the time they get to the end of the process and they see that the water is so clean—you almost want to drink it! (laughs)

LOBET: And from here, the end of the sewage treatment process, it gravity-drains to the water utility, right next door. There, three things happen. None by itself is unique or too remarkable but taken together, and used on wastewater, it's the largest project of its kind in the world. First the water is sucked up into thousands of stringy straws with perforated sides.

[SOUND OF MICROFILTRATION]

LOBET: Bugs like protozoa and bacteria in the water can't fit though the holes. So every 22 minutes the airflow reverses to blow instead of suck, to clean the holes. The impurities are promptly sent back across the property line to the sewage treatment plant. Ron Wildermuth of the Water District loves the sound.

WILDERMUTH: It's like an orchestra.

LOBET: Music to your ears?

WILDERMUTH: Yes it is! (laughs)

LOBET: Next, the water passes though chambers for reverse osmosis. That means the water molecules are actually forced, under intense pressure, through a sheet of plastic. Wildermuth says not much besides tiny water molecules can pass through.

WILDERMUTH: If you size a water molecule the size of a tennis ball, your pharmaceuticals, hormones, pesticides—would be the size of a soccer ball. Okay? A virus would be the size of a tractor-trailer truck. So basically we’re physically not allowing viruses, uh, fertilizers, pesticides, hormones, or pharmaceuticals to get through because they can't get through the plastic sheet.

LOBET: Last, the water is exposed to ultraviolet light and mixed with peroxide. That zaps two compounds that manage to get this far for final cleaning. The engineers here at the water utility brought all this new equipment online over the last three months. The day before my visit had been a milestone. For the first time they'd injected their new purified water underground. William Dunivin is in charge.

DUNIVIN: To see it all come together after so many years it’s like, I can't explain it. And just the fact that it's such a, a timely event for the world to see this. I mean, with water becoming such an issue throughout the world. And this is a viable way to do it, and safely.

LOBET: A steady stream of visitors from around the globe tour the project. At home, it's been the focus of an intense public relations, okay, public education campaign. Again, Ron Wildermuth.

WILDERMUTH: We thought we could convince the people this was a good idea, and we did.

LOBET: How did you do that?

WILDERMUTH: Face to face talks for ten years to everybody that would listen. We talked to the historical society. We talked to the chambers. We talked to the flower committee. If there was a group, we talked to them.


Orange County will soon use purified wastewater to replenish sinking groundwater. (Courtesy of Orange County Water District)

LOBET: And consistent with the positive message, the water district has a stainless steel tap ready for a taste at the end of every tour.

WILDERMUTH: Very good water.

LOBET: For those not persuaded by the positive, consider this: many of us are already drinking water that was discharged as treated sewage into a river, and then tapped and purified downstream.

WILDERMUTH: Las Vegas puts like 200,000 gallons of wastewater in Lake Mead every day. And that comes down to us. It’s nothing new.

LOBET: But we haven't been talking that much about it.

WILDERMUTH: You're darn right we haven't. But, you know, it's a fact of life.

LOBET: For Living On Earth, I'm Ingrid Lobet in Fountain Valley, California.

Northwest Dead Zone

CURWOOD: You’re listening to an encore edition of Living on Earth. I’m Steve Curwood. We like to picture the ocean as teeming with life – with fish and crabs and strange glowing eels. But in many parts of the world the ocean is dying. There are currently about 200 dead zones almost all of them caused by fertilizer or sewage run-off. But one dead zone off the coast of the Pacific Northwest has been expanding over the past few years, for causes that are harder to fathom. Joining me now is Professor Jack Barth of the College of Oceanic and Atmospheric Sciences at Oregon State University. Professor Barth, welcome to Living on Earth.

BARTH: Thank you, Steve.

CURWOOD: So the news is, the dead zone off of the Pacific Northwest might well be connected to climate change. How and why would that be?

BARTH: Well, we've seen low oxygen or hypoxia in these areas where there is significant green life die-off, so-called dead zones. We've seen that over the past five or six years, and we think that's unusual on the backdrop of about a fifty year's worth of data. So we're looking towards the cause, and we think there's a hint in the winds and how they're changing and how that affects these dead zones.

CURWOOD: There're lots of dead zones around the planet. Why would this be different?

BARTH: Well, this one's unusual because it's on an open coastline. It should be flushed regularly. There are no rivers putting nutrients in – that's the cause of most of the hypoxia zones around the world. Well it's all connected to the winds. The winds blow on the coast, they bring up these deepwaters from offshore, right in next to the coast. That fuels these phytoplankton blooms that then decompose and pull the oxygen out of the water. So we can go back to the winds, are the winds changing? And we know that with climate change there can be changes in the wind. Particularly they can increase in strength, so this whole scenario where we're producing lots of plankton that can decompose, that might be worse as we go into a climate change scenario.

CURWOOD: Why isn't this, you know, just something that's cyclical, that every ten or twenty, or maybe every fifty years this happens, the way you get other oscillations in the ocean, like the whole El Niño/La Niña phenomenon?

BARTH: Yeah, we were quite interested in that. There's a big ten-year change out here in the Pacific, and when we first saw this we said, ah ha that's just one of these ten-year swings. But having gone back over that fifty-year record, this recent five or six years really is unusual. So I can tell you that it's not part of a decadal, or a ten-year oscillation. Whether it's fifty or a hundred years, we don't know.

CURWOOD: What do you see in this dead zone?

BARTH: Well, first thing you notice, there's lots of something called marine snow, this white, flocky material coming down from the surface. That's the plankton falling down that's gonna be decomposed and lead to the hypoxia. Next thing you notice is there aren't any fish in the area. So in all of our surveys in '06, we did not see any fish in this zone. Then you notice the piles and piles of Dungeness crab carcasses on the sea floor. Amongst them are sea worms that have come out from the bottom and are just flapping in the currents. Some of these majestic anemones, white, about two feet tall, starting to slump over from lack of oxygen. There usually are lots of sea star species. We saw some of those actually collapsing from lack of oxygen – so basically this wholesale area of nothing alive and lots of death.

CURWOOD: Going over a couple of articles written about your research, there was a story of some fisherman having crabs kind of jumping out of the water there? What's that all about?

BARTH: Yeah, what happens is those that can get away do. And what I saw myself is, my son and I go recreational crabbing, and we were in the bay near the dead zone and catching phenomenal sized crabs, sort of dinner plate sized in fifteen minutes or less. And those were the crabs that were running into shore, running into shallow water where there is oxygen. I've also heard reports of small octopi coming up the lines of the fisherman, trying to get out of that dead zone near the bottom of the water.

CURWOOD: And this isn't happening just off the Pacific Northwest. This is elsewhere on the planet.

BARTH: Yeah, we know of two other areas. There's – the area off Peru and Chile has a similar hypoxia zone. The one off South Africa and Namibia is quite interesting. They actually get walk-outs of lobsters onto the beach, fleeing the dead zone in that region.


Seastars feasting on Dungeness crabs that succumbed to low-oxygen conditions during 2004. (Photo: Jane Lubchenco)

CURWOOD: So what an irony this is. The wind blows in too much food for the fish, and actually if people are in the area, the fish, in fleeing the dead zone as that too much food decays, also they get this huge bounty. So we're getting this inverse signal from nature that a lot of nutrient and, over the short term, a lot of seafood.

BARTH: Yeah, that's exactly right. If you think about this whole process as fueling a healthy ecosystem, there was a balance there and now somehow we've pushed that a little too far, and as these dead zones develop the creatures are fleeing to the edges looking for oxygen refuges and concentrating, and we're really not sure what the ripple effect will be – will they be more subject to being preyed upon in those areas?

CURWOOD: Professor Jack Barth teaches at the College of Oceanic and Atmospheric Sciences at Oregon State University. Thanks so much, Jack.

BARTH: You're welcome, Steve.

Dial-A-Fish

Not this kind of fish phone! (Photo: Sue Allen)

CURWOOD: When you’re in a restaurant or a grocery store, thinking about fish for supper, you might also want to think about what could be in the fish—maybe mercury, perhaps PCBs? Or maybe the fishery is floundering. Some fish are good—some not—but can you remember which fish is which? Now you don’t have to—you can let your fingers do the fishing, as Living on Earth’s Ashley Ahearn learned when she dialed-a-fish at her local supermarket.

[SOUNDS OF GROCERY STORE, BEEPING, PEOPLE WALKING]

AHEARN: So I’m going to type in ‘swordfish’ and see what comes up.

[CELL PHONE TEXT MESSAGE SOUND]

AHEARN: It says; Atlantic and Mediterranean caught, few environmental concerns. It got a green rating. And they’re high mercury, though. Okay, so maybe I won’t do swordfish. I’m trying salmon now.

[CELL PHONE TEXT MESSAGE SOUND]

AHEARN: But for wild salmon it says it’s fine. So I guess farmed salmon is off the menu for dinner, too.

So yeah, that was me with my cell phone, talking to myself at the local market. As crazy as I might have looked, though, this service is really cool. It’s called Fish Phone. The guy who dreamt it up is Carl Safina, head of the Blue Ocean Institute. I called him to find out how it works.

SAFINA: You simply send a text message with the word ‘fish’ and the name of the fish that you are interested in and virtually instantly, you will get a beep on your phone and you will see whether you should tell the waiter that that’s what you want to eat or you should tell the guy behind the counter or the woman behind the counter that that’s what you want to buy.

AHEARN: So it’s kind of like cheating in a way.

SAFINA: Uh, it’s kind of like being a very informed consumer and feeling kind of smug about it.

AHEARN: Carl Safina and his team have put together a database that rates each fish based on pollution exposure, fishing practices, population levels, even how long it takes that species to reproduce.

SAFINA: And then we score all those things and then we relate the score to a color code and the code sort of ranges from green to light green to yellow to reddish yellow to red.

AHEARN: I think Dr. Seuss wrote a poem about that.

SAFINA: Yes, he did (laughs). Maybe subliminally that was our inspiration all along.

AHEARN: But beyond the rating system, Carl has some basic rules of thumb for anyone buying fish, even if they don’t have text messaging on their phone.


Not this kind of fish phone!(Photo: Sue Allen)

SAFINA: Farmed shellfish is generally very good and then the smaller the fish is, the better it’s likely to be. The bigger the fish, the more fished out it probably is and the more you might have a concern about mercury or other pollutants. But there are some surprises. For instance, the swordfish have come back up and they’re doing much better than they were a decade ago.

[SOUND OF GROCERY STORE, BEEPING AND PEOPLE TALKING]

AHEARN: That doesn’t really help me for dinner, though. Swordfish is a little bit out of my price range. But Safina says farmed shellfish is good. So, I’ll text the number 30644, the word ‘shrimp,’ and let’s see what my phone spits out now.

[CELL PHONE TEXT MESSAGE SOUND]

AHEARN: Oh, okay, so if I get farmed shrimp, I’m okay, it looks like, from here. So shrimp it is for dinner. Thank you Carl Safina. Thank you Fish Phone. Alright, great. Can I get a half a pound of the farm-raised—

For Living on Earth, I’m Ashley Ahearn.

Interpreting History

Park Ranger Shelton Johnson becomes Sergeant Alizy Bowman to tell the history of the beginnings of Yosemite National Park. (Photo: Melissa Frank)

CURWOOD: Two hundred and fifty million Americans visit our National Parks every year. We have nearly 400 of them in all. Most of them are patrolled by rangers who protect the park and talk about its geography, geology, plants and animals. And some feature interpretive rangers, who take on a character to help visitors understand the unique history of the park. One such ranger welcomes visitors to one of the most beautiful spots in the West, Yosemite. Jim Williams of member station KUMN caught up with this ranger in action.

JOHNSON: Have you noticed there’s just so much sky here? I think there’s a overabundance of sky in Yosemite. I wonder if the sky needed to get a permit from the government to have so much of itself over here.

WILLIAMS: South Carolina native Sergeant Alizy Bowman stands surrounded by fifteen or so wide-eyed Yosemite visitors. He’s decked out in his tan 9th cavalry finest. The crossed swords on his brimmed military hat flash in the bright sunlight.


One of Yosemite's best known landmarks: El Capitan (Photo: Jon Sullivan)

JOHNSON: So now I’m going to tell you why it is the military was brought in here. When Yosemite was created as a National Park on October 1st, 1890, Congress neglected a little thing that ain’t so little. They forgot to supply adequate funding for the protection of the park. This woman’s in shock. She can’t believe the government would not see that clearly was an issue. If you have a national park and you don’t have someone to protect it, it could be a problem. Because how many of you folks think that Yosemite is a place beyond value?

WILLIAMS: Everyone in this group raises a hand. It’s not surprising: Bowman is using Half-Dome as his own personal backdrop—the nearly-vertical granite cliffs shine through the massive incense-cedars and ponderosa pines on the Yosemite Valley floor. And of course, this isn’t really Sergeant Alizy Bowman. It’s Shelton Johnson, an African-American Interpretive Ranger who’s essentially reincarnated the sergeant’s character. In fact, Johnson’s been getting into this character in front of visitors here for about five years now. From his research, Johnson found out that Sergeant Bowman was a Buffalo soldier, a member of a group of African-Americans who helped guard Yosemite just after its creation. Bowman spent several summers in the early 1900s patrolling the backcountry looking for poachers and timber-thieves.

JOHNSON: And the people in this county—Mariposa County—are used to coming up into these mountains and getting what they want, what they need to help their family from these mountains. People come up here, and have for years, to shoot the game, to cut the trees down for firewood, and all of a sudden, the government steps in and says that there’s a line right here. Right here. And that line, on this side, is Yosemite National Park. On that side is Mariposa County. Now how many of you see that line? If you from Mariposa County, there ain’t no line there at all.


Sergeant Alizy Bowman, aka Ranger Shelton Johnson, plays his flute for Yosemite National Park visitors. (Photo: Melissa Frank)

WILLIAMS: It’s a surprise for many: the Buffalo Soldiers who fought for the United States in the Philippines and in Mexico during the Spanish-American war, later joined white soldiers to guard several western parks. The young African-American men, many of whom had enlisted to escape the discrimination of the South, found themselves faced with a new kind of trouble in the western wilderness.

JOHNSON: I gotta ask you folks something: is there a nice way to call someone a timber thief and a poacher? And if we were in Mississippi, or Alabama, or Georgia, and I was gonna call a white man a timber thief and a poacher, ain’t there a word for that down south? Oh, I remember, it’s called suicide.

[LAUGHTER]

WILLIAMS: The laughter turns to quiet, and there’s a moment here where Johnson’s audience seems to consider something a bit deeper, but the ranger moves them on quickly to another spot, playing his Native American flute along the path.

[FLUTE MUSIC]

WILLIAMS: He stops, points to a place for the kids to sit in the shade, and Alizy Bowman is back.

JOHNSON: Man, do you think I got a bit of a attitude?

WILLIAMS: He explains that he’d had an attitude growing up in Spartanburg, South Carolina, which didn’t go over well in the late 1800s. It’s a big part of the reason he ended up a Buffalo Soldier. His father, he says, told him to leave home as a teenager and walk north, which he did. Then he went west, eventually ending up in Fort Robinson, Nebraska, where he was extended an offer to join the Army. Bowman says as he held the pen to sign his enlistment form, he remembered that his brother had died in the Civil War, after having escaped slavery in South Carolina.

JOHNSON: My brother had done the same thing I was about to do: make a mark on a piece of paper. And that’s what I remembered. And I heard in my head this: (Singing) There’s a man goin’ round takin’ names. There’s a man goin’ round takin names. He has taken my brother’s name, and he’s left my heart in pain. There’s a man goin’ round takin’ names. Oh death is that man takin’ names.

WILLIAMS: Johnson bases his performance on his late father’s personality, and says through the performance, his father, and the Buffalo Soldiers, live on.

VISITOR: Thank you so much!

JOHNSON: You’re welcome. Thank you.

WILLIAMS: And for the visitors here today, none of whom are African-American, the impact is clear.

MAN 1: This man has a true gift as a storyteller. I would come back every day to hear this if I could. I feel like I’m a lot better educated about it, and I really appreciate that.


The intricate lacing of the spats of Sergeant Alizy Bowman's 9th cavalry uniform. (Photo: Melissa Frank)

MAN 2: Well he brings it to life in the way that he’s dressed. He’s got the Buffalo Soldier outfit on. I’m still trying to figure out how he tied his leggings on.

JOHNSON: It’s a secret.

MAN 2: Yeah, I figured it was a secret. He just acts the part really, really well.

WOMAN: It just makes it a much richer experience than having, you know, someone tell you about history, it gives you the feeling of experiencing history.

MAN 3: And I think the country’s probably full of stories like this if we really knew the history and the individuals who were involved in these things.

WILLIAMS: Johnson says for him, the opportunity to share Bowman’s character with park visitors is too good to pass up.

JOHNSON: I think that this story provides a cultural window. A window into another way of looking, into another way of being—that some people have never looked through that particular window. And so this provides them an opportunity to not just see another person’s point of view, but to see themselves through that other window, how they may be seen through that other window.

WILLIAMS: But Johnson believes he’s also having an impact on African-American park visitors.

JOHNSON: They come into this setting and there may be some anxiety, because it’s away from urban areas. They’re doing something that a lot of African-Americans historically have not done in terms of visiting national parks and wilderness areas. And so when they hear this story, it’s like a safe-house, or an environment of not necessarily comfort, but it gives them a sense that ‘oh we belong here, this is the place that we’ve done this work, that we helped protect. This is our park.’ And they start seeing Half Dome, they start seeing El Capitan in a completely different way, because now it’s part of the African-American experience, to be in Yosemite.

WILLIAMS: Johnson regularly does his Alizy Bowman presentation for kids of color from nearby places like Fresno, Los Angeles, Sacramento, and San Francisco. The kids come to understand that some of Yosemite’s earliest protectors faced some of the same challenges they face today. Johnson says, for him, it’s also a way to make sure the history book isn’t missing a chapter.

JOHNSON: I think that stories that are forgotten, that we pay no attention to, just fade away, like an old soldier, you know? But stories that get that attention, that engage the mind, that engage the vision, that invigorates the story, that puts blood into the story, and the story can just live and live on and live on and live forever.

[FLUTE MUSIC]

WILLIAMS: And to help ensure just that, Shelton Johnson is writing a book on the Buffalo Soldiers of Yosemite. It’ll be called “Gloryland.” He’s also been interviewed by Ken Burns for a PBS documentary on the parks. His is a rising star, and Alizy Bowman is right there rising with him.

For Living On Earth, I’m Jim Williams from Yosemite National Park.

Global Weirding

CURWOOD: Coming up: the year of eating locally. Pass the beets and rhubarbs, please. Stay tuned to Living on Earth!

ANNOUNCER: Support for the environmental health desk at Living on Earth comes from the Cedar Tree Foundation. Support also comes from the Richard and Rhoda Goldman Fund for coverage of population and the environment. And from Gilman Ordway for coverage of conservation and environmental change. This is Living on Earth on PRI—Public Radio International.

CURWOOD: It’s an encore edition of Living on Earth. I'm Steve Curwood. And now, a few words from our listeners.

[LETTERS THEME]

CURWOOD: Recently, we asked you if you could come up with better terms than "global warming" and "climate change." You certainly had some ideas:

IAN QUIRK: I think it should be climate imbalance, which implies some places are gonna get much hotter and some places are gonna get much colder, but either way we have no way of predicting how that's going to happen.

BONNIE BISHOP: What to call global warming instead of global warming? And from the beginning, I've said we should call it global trauma.

LEON FROM CHICAGO: The topic of the climate change, how it should be called – well, it should be called climate change.

MARTIN SLOVINSKY: Human consumption climate disruption; human consumption climate disruption

CURWOOD: Your e-mails also think 'global.' There was 'global life system instability' and 'global climate disruption,' 'global climate damage' and 'global climate melt-down.' One writer suggests 'global temperature destabilization,' noting that it's 'harder to say and spell, but more descriptive.' Also pretty hard to say is this offering – anthropogenic climate disruption. And still the phones kept ringing off the hook:

PETER WALE: In our household, when we run into difficulties with the terms global warming or climate change, we resort to a more technical term, ebbifluid acceleration.

AHMEEL MERRITT: How about we call it global abuse?

ANNA VON BILLINGEN: The new suggestion for what we're calling how we're trashing our planet would be global dumping.

CARBON INFUSION: I heard a good one. It sounds right to me – carbon infusion. Deadly carbon infusion.

CURWOOD: Many thanks to all who took the time to call and write, including Ian Quirk, Anita Schnee, Martin Slovinsky, Ahmeel Merritt, Bonnie Bishop, Jack Ciak, Peter Wale, Terry Watts, and Anna Von Billingen. We're always glad to hear from you. You can call our listener line any time at 800 218-9988. That's 800-218 99 88.

Life As a Locavore

Barbara Kingsolver and family. (Photo: Hank Daniel)

CURWOOD: Barbara Kingsolver left life in the farm country of Kentucky in the 1970s to become educated as an evolutionary biologist. But what she didn’t know was that she would also become a best-selling novelist. You may know some of her titles: “The Poisonwood Bible” is one “Prodigal Summer” is another. Now she and her husband and daughter have a volume that documents how her family carried out a vow to eat only locally grown food for one year. The book is called “Animal, Vegetable, Miracle; A Year of Food Life.” Her family produced about seventy percent of what went on their table from their own farm in Virginia—everything from tomatoes to turkeys.

What they couldn’t grow they mostly bought from local farmers. I spoke with Barbara Kingsolver and asked her what motivated her and her family to become what’s known as locavores—people who eat locally.

KINGSOLVER: We were led into this project for so many reasons. For me, it’s because I grew up in a rural community among farmers and I’ve always considered the local farming economy to be important and frankly an important part of food security. We are now, as a nation, putting almost as much fossil fuels into our refrigerators as our cars. Every item on average on the American plate has traveled 1500 miles so add up all the items on your plate and you might as well order room service from the moon!

That’s an incredible amount of fossil fuel, an incredible amount of carbon emissions going into the atmosphere, warming up the globe just to get a grape from Chile, a tomato from Mexico so I can eat a tomato in January.

CURWOOD: Now, you write in your book that 80 percent of us in America would love to eat organic and locally grown foods yet the American government through the farm bill gives just about all federal money to the biggest farms in the country and most of them grow things like corn, soybeans, and wheat far from where most of us live. Can you talk to me more about that?

KINGSOLVER: I’m so glad you brought that up. U.S. taxpayers pay tens of billions of dollars every year to subsidize the production of commodity crops which are, as you mentioned, mostly corn wheat and soybeans. Most of that production enters our diets without our notice as the ingredients of processed foods like high fructose corn syrup and feed to raise cattle and hogs. And we also as taxpayers subsidize the fuel costs of getting these products manufactured and shipped to the market.

So it’s a funny thing in this country we think of fast food as cheap in spite of all the fossil fuels and processing that were required to make it while we think of simple unprocessed organic produce as sort of elite, an expensive option. It’s incredibly ironic that the US government urges us to eat more fruits and vegetables but our agricultural programs offer virtually no assistance to fruit and vegetable growers.

CURWOOD: About what did it cost you to grow your own food and buy the rest of it locally?

KINGSOLVER: You know what, we were stunned by the answer to that question. I kept really careful records and I found out that we spent about 50 cents per person per meal to eat as splendidly as we did in this year. And I thought this must be a mistake so I went back and I recalculated and that was it: 50 cents per person per meal.

CURWOOD: So, for those of us that are used to having orange juice for breakfast, how were you able to pull this off? I mean eating locally, growing it yourself or getting it from local farmers means for example you’re not going to have orange juice for breakfast there in Virginia.

KINGSOLVER: You start by accepting this will be a paradigm shift. This will be a change in the way you think about food and as time went by we really learned to stop asking the question, what do I want right now? And instead start seeing each week as something like the menu in a restaurant: Look at what’s available. What do they have? What’s growing this week? What’s fresh and delicious and choose from that.


The “vegetannual,” a term invented by Barbara Kingsolver to describe when fruits and vegetables are in season. (Courtesy of Barbara Kingsolver)

I do want to point out that we weren’t the strictest locavores. We didn’t for example give up coffee because my husband said, “Coffee will get you through times with no food better than food will get you through times with no coffee.” And I began to understand important things about my marriage.

CURWOOD: Now you were a vegetarian for many years but as part of this project you decided to raise and slaughter your own meat. Talk to me about how and why you came to that decision.

KINGSOLVER: It’s really important to know that food is not just a product but a process. There are two very different ways of producing meat. One of them is concentrated animal feeding operations or CAFOs. These are feed lots for cattle or metal windowless warehouses for hogs, turkeys, chickens and so forth where they’re crowded as close as they possibly can be and these very concentrated populations require that all of their food be milled and processed somewhere else and brought in and then all of the concentrated waste have to be trucked out to somewhere, heaven only knows where. And these animals get fed this porridge of the cheapest ingredients just for the efficiency of producing cheap meat. And also they have to be given antibiotics in order to keep them alive under conditions of extreme physiological stress. So that kind of meat I hadn’t eaten for many years.

There is another way, a different way of raising meat, and that is keeping these animals on pasture. And the interesting thing from an energetic point of view is that they can do all this without using a drop of gasoline. In the county where I live we have a lot of steep grassy pastures. And we can use this as a solar-powered industry to make meat. And that’s the food that my grandparents got through the winter on and we felt that we could do the same and we even raised turkeys and chickens of our own.

CURWOOD: Now, there’s a great scene in your book when you’re getting ready to have a party in the early spring. Around your birthday I guess.

KINGSOLVER: Yeah.

CURWOOD: And you’d only been at this a little while. I mean you didn’t have last year’s canned goods or anything stuck in your freezer that you could trot out here.

KINGSOLVER: Right. We began thinking this is a pretty bleak time of year. May is still pretty early where we live in the mountains of southern Appalachia. There’s not a lot coming up just yet. And we were thinking, oh this is going to be the borsht party beets and potatoes. But as a matter of fact as happened over and again in this project, what we found was so much more than we were looking for. There were terrific salad greens. There were asparagus there were eggs so we could have asparagus frittatas. There was rhubarb and strawberries so we could have strawberry rhubarb crisp. There were lamb and oh wow we had chicken pizza. There was so much that was just literally down the road from where we lived, so much more than we expected. And it turned out to be a terrific event because it reinforced to us this isn’t a story of deprivation. This is a story of gratitude.

CURWOOD: Now, where you are in Virginia, you’ve got a farm, a lot of neighbors who are in the food business. But what about somebody who lives in say the city or say a colder climate. What kind of advice would you offer for taking steps to eat more locally?

KINGSOLVER: Being thoughtful about food life is not of course about growing your own. Anyone who has choices about food can exercise them with more care even in the cities and especially in the cities. Every grocery store that carries multiple brands will have some that are produced closer to home than others. We can all emphasize whole ingredients more and pass up processed goods that have so many hidden costs. And the next stop of course is the farmer’s market. More than half of all of us living in the US live within striking distance of a place where farmers sell their own produce. Also many cities have community gardens. I think there are 114 of them in Manhattan alone. Any way you cut it getting to know your own food chain is neighborly and it’s healthy. It keeps your money in your own community and it keeps the land around you a little more green.

CURWOOD: So you eat locally for a year and you lived to tell about it and the day this project was finished did you run out for what uh maybe uh…

KINGSOLVER: Coca Cola and moon pies? No, we didn’t. We forgot to notice the day the project ended. By this time it was just the way we lived. We have a new relationship with where we live. We are what we ate.

CURWOOD: Barbara Kingsolver’s new book is Animal, Vegetable, Miracle; a Year of Food Life. It was written with her husband Steven L. Hopp and daughter Camille Kingsolver. Barbara, thank you so much.

KINGSOLVER: Thank you, bye.

[MUSIC: “Tree Hugging Song” from Children Of The Earth: Environmental Songs for Kids Of All Ages (Joe Reilly Music 2007)]

CURWOOD: How could we live without trees? That’s the question singer-songwriter Joe Reilly, and the youngsters he works with in Ann Arbor, Michigan, ask in that “Tree Hugging Song.” It’s from a new CD he’s produced, called “Children of the Earth.” Joe Reilly wants to spread the word about good environmental stewardship.

But he wants to entertain as well, with songs about nature, and animals, of all kinds.

[MUSIC: Joe Reilly “If I Could Be Any Tree” from ‘Children Of The Earth: Environmental Songs For Kids Of All Ages’ (Joe Reilly Music—2007)]

REILLY: My parents are both musicians. They’re both singers, and my dad plays the upright bass, as well. And they both play guitar. And so I grew up, really, literally, since I was in the womb with music all around.

REILLY (singing): …. Amphibitti – phibitti-phibitti-an…. Amphibitti – phibitti-phibitti-an …..(fades under) [Joe Reilly: “Amphibians” & Mammals are from a live performance for LOE]

REILLY: On the CD I really wanted to include the kids’ voices as part of the message, and as part of the expression. And so, I invited the kids to sing with me on several of the songs and then, I also interviewed them. I just wanted to give them a voice because I feel like, you know, the small voices are not heard and I wanted to give a little space on my project for those voices to come through.

So I just asked them questions like “What’s important to you about the Earth?” “Why do you care about nature?” “Why do you care about the Earth?” “What message do you have for adults and for the world about what we can do to help the Earth, to help heal the Earth?”

CHILD 1: You should ride your bike in the summer or whenever it’s warm enough to ride your bike instead of using a car because it’ll give you exercise and it will help the Earth.
CHILD 2: to use cars that use sunlight and no gas.
CHILD 3: using public transportation is better because it keeps more cars off the road.
CHILD 4: try walking.

REILLY: My hope is that those voices can help remind adults that we need to really take responsibility for our actions and how they’re affecting other people and other plants and living things and the future generations.

REILLY: (singing) Dogs, cats, hedgehogs, camels, these are all animals known as mammals. Horses, rabbits, humans, too, that’s right, I’m a mammal…..(fades under) [“The Animal Song” from Children Of The Earth: Environmental Songs for Kids Of All Ages (Joe Reilly Music 2007)]

REILLY: I guess sometimes I’ll sit down with a group and say “What do you want to write a song about?” and then they may shout out something like “mammals” for instance. So, okay, so we have a topic – mammals – and so, describe to me what a mammal is. You know, tell me, what are different examples of mammals, what are the habitats that mammals live in?

REILLY (singing): Deer and rabbits are mammals in the forest, so many mammals that we have to sing our chorus. It goes: Dogs, cats, hedgehogs, camels, these are all animals known as mammals

REILLY: I was thinking about, you know, the process of songwriting. It’s kind of a hard process to describe but working with kids and writing songs has been really helpful to me. I’ve learned a lot about how to just be open to possibilities that I might not have thought of when first starting to write the songs.

REILLY (singing): I am a crow, and I sound like CAW, CAW…(KIDS JOIN IN) We are all brothers and sisters…

REILLY: It’s my hope that this album, that this project can be a source of connection for kids. That it can help them build relationships to the Earth that are sustaining for the Earth, but also for the kids, for the kids’ sake.

REILLY (singing): I am a little kid, I live in Michigan….

REILLY: I think I’ll always be a teacher. My mom’s a teacher, my grandma was a teacher, and it’s in my blood (laughs) and so I think, you know, I’ll always be an environmental educator ‘cause that’s something that is so true to me and I’ll always be a songwriter so these are things that I carry with me…whether or not they pay the bills, that’s up to the universe (laughs).

REILLY (singing): We are all brothers and sisters, we are all related.
