How KFC and the Tea Party Kill Tigers

The World Wildlife Fund captured two tigers on camera deep in the forest of central Sumatra, which is threatened by loggers.

Over at Yale E360, you can watch a great World Wildlife Fund video showing the areas of the Sumatran rainforest slated to be logged in the near future. Sumatra is home to a pretty astounding array of wildlife, including rhinos, orangutans and tigers. Last week, WWF released rare footage of 12 critically endangered tigers in the area, including a mom and two cubs. Only about 400 Sumatran tigers are left in the world. 

The video mentions one particular company responsible for much of the Indonesian rainforest destruction: Asia Pulp & Paper, a major subsidiary of the Sinar Mas Group, an Indonesian mega-conglommerate known for its cozy relationship with the Suharto family. APP's realm of influence is truly vast: The 5 million tons of paper it produces annually are sold in 65 countries on six continents.

APP has long been on environmentalists' radar; it has been accused of illegal logging in Cambodia and Indonesia, and a 2008 investigation by the rainforest advocacy group Eyes on the Forest suggested that companies connected to APP had illegally built a road through a part of Sumatra that was one of the world's biggest carbon stores.

And yet APP still has a firm hold on the US paper market. According to Greenpeace, KFC and several other fast-food chains owned by Yum Brands are among its major US buyers. And it enjoys political support, too: In March, the New York Times reported that the Tea Party-affiliated group Institute for Liberty has been lobbying to protect APP's right to sell paper products to the US without having to pay tarrifs. (The Insitute for Liberty is known for its massive pro-business astroturfing efforts;it has defended Monsanto's right to sell genetically modified alfalfa, and MoJo's Stephanie Mencimer recently reported on its campaign against net neutrality.)

APP has tried to spiff up its environmental rep with a major PR push; its website claims that it is "committed to protecting biological diversity, particularly with regards to native plant species, Sumatran tigers, elephants, orangutans, birds and other animals." The site also brags that APP's carbon footprint is "remarkably close to neutral." But last year, the Rainforest Action Network revealed that APP's calculations of its footprint are sorely lacking, since they don't take into consideration the carbon-storing peatlands that APP has destroyed.

Despite the greenwashing, APP's lousy environmental track record finally seems to be catching up with it; several American chains, including Staples, Office Depot, and Target, recently ended their contracts with the paper giant. Will others follow suit before it's too late for the tigers?

Bikers Weather Pollution Better Than Drivers

On the heels of Bike-to-Work Day comes this excellent little bit of news: Bike commuters are less affected by air pollution than car and bus commuters, according to a new study published in the journal Epidemiology. The researchers found that even though bikers were exposed to more air pollution than vehicle passengers, their airways were less inflamed after the commute:

The Netherlands' researchers measured three factors related to breathing ability – lung function, airway resistance and airway inflammation – among healthy, 18- to 56-year-old volunteers before and after they commuted for two hours by bus, car or bicycle. These measures were related to estimates of two sizes of particles (PM2.5 and PM10), the number of particles in the air and soot the commuters inhaled.

[...]

Car and bus commuters experienced more inflammation based on the amount of particles present and soot concentrations. While bicycle commuting exposed participants to higher levels of pollution, health effects were not changed among the bikers.

No word on why this is the case, but I'm tempted to chalk it up to the superior lung capacity of bikers.

 

Have Nut Allergies Been Cured?

Growing up in the '80s and '90s, I was the only kid I knew who was allergic to nuts. I remember explaining to a skeptical teacher why I couldn't eat the walnut brownies she'd brought for us one day. "But how do you know you won't like them if you won't even try?" she asked. Times have changed. You'd be hard pressed to find a gradeschool teacher now who wasn't well versed in EpiPens and anaphylactic shock; some school cafeterias are now nut-free zones. Indeed, nut allergies are on the rise. Last May, researchers at the Mt. Sinai School of Medicine found that the rate of childhood peanut allergy had more than tripled in recent years, up from .4 percent in 1997 to 1.4 percent in 2008.

No one is quite sure why allergies are becoming more common. One theory called the hygiene hypothesis speculates that the environment in developed countries is actually too clean: Since children no longer encounter the full array of germs and parasites they once did, their immune systems instead busy themselves reacting to pollens, molds, and certain proteins in foods. (In developing countries allergy rates are vanishingly tiny.) The allergy onslaught has also been linked to climate change; immunologists have long connected the rise in hay fever cases to global warming, and in 2008 an Ausrtralian researcher suggested (PDF) that climbing temperatures could be making certain foods more allergenic as well.

When I was diagnosed with nut allergies as a baby, my parents were told there wasn't much they could do about it, short of keeping me away from the offending foods and carrying an epinephrine shot in case I accidentally ate something nutty and developed an anaphylactic reaction. But in the past few years, pioneering immunologists have been experimenting with a new therapy for nut-allergic kids. Called oral immunotherapy or desensitization, it exposes patients to gradually increasing doses of nuts, with the aim of increasing their tolerance. The results so far have been promising. In the first study of the technique at Duke University, five out of seven participants were able to tolerate eating the equivalent of 13 peanuts by the end of the roughly two-year trial. Subsequent studies of other nuts, eggs, and milk, have shown similarly positive outcomes.

So will allergic kids soon be able to shed their EpiPens and MedicAlert bracelets? And will I get to order pad thai without all my friends chorusing to the poor waitress, "No nuts please!"? 

For the inside scoop, I spoke with Dr. Jeffrey Factor, who runs the New England Food Allergy Treatment Center, an oral immunotherapy clinic in West Hartford, Connecticut. Since last November, Factor has been treating 40 peanut allergy sufferers between the ages of 5 and 20. Here's what the process entails: On the first day, the patient comes into the clinic and ingests a minuscule amount of peanut flour (while hooked up to an IV so that epinephrine can be administered if needed). The dose of peanut flour is increased every half hour until it reaches 6 miligrams of peanut protein. Then, at home, over the course of the next two weeks, the patient takes a daily dose of 6 miligrams of peanut flour mixed into applesauce or pudding. After that, he or she comes in for a "dose escalation," so the clinic staff can monitor for reactions. The process repeats, with gradually increasing doses, for 20-24 weeks, at which point most patients reach the equivalent protein of 2-3 peanuts.

So far, the results have been encouraging: Some patients have progressed more slowly than others, but several are one or two doses away from being able to tolerate 2-3 peanuts. Factor hasn't had to treat any of the patients with epinephrine or drop anyone from the study because of systemic reactions. Still, he's careful to note that even the patients who reach the maintenance dose are still advised to avoid peanuts. Their allergies are not cured, just better controlled.

A few caveats: Since the therapy isn't covered by insurance it costs patients a whopping $5,000 out of pocket. Plus, so far, the trials have been limited to children. Factor, who is himself allergic to tree nuts, would like to see the therapy expanded to adults in the near future. But even if it is, it's unlikely that I'll ever be able to skip the "Are there nuts in that?" part of dining out. "The goal is not a cure," he says. "The goal is peace of mind about reactions." Peace of mind might not taste as good as pad thai, but you know what? I'd probably take it.

Correction appended: An earlier version of this story stated that patients received peanut flour through an IV on the first day of treatment. Actually, all peanut flour is ingested orally. We regret the error.

Since Fukushima, Chernobyl Tourism on the Rise

Via Der Spiegel, I learned a fun Earth-Day's-Eve fact: At Chernobyl's infamous defunct nuclear power plant, you can take a tour that includes a Geiger counter and lunch in the plant cafeteria. This spectacle attracts a particular kind of tourist:

For her visit to the danger zone, Margarita from Italy has chosen to wear leopard-print linen shoes and pink lipstick. Her eyebrows are dyed lime green, her dark hair blond. "I lead a dangerous life," says Margarita, who is in her mid-twenties, in a breathy voice. "All the dye in my hair is also harmful to my health."

And in the wake of the Fukushima disaster, more and more edgy tourists like Margarita are flocking to Chernobyl: According to Der Spiegel, tours have been sold out since Japan's nuclear problems began.
