The syndrome, which can make you allergic to red meat, is spread by a type of tick that has become more common in Rhode Island. What should you know to stay safe?

Megan Hall: Welcome to Possibly, where we take on huge problems like the future of our planet and break them down into small questions with unexpected answers. I’m Megan Hall.

It’s almost summer, which means barbecues and beach days, but also ticks. You probably know that ticks carry Lyme disease, but now they’re also spreading a disease that you might not have heard of…

Meg Talikoff and Nat Hardy from our Possibly Team are here to tell us what we need to know. Hey guys!

Nat Hardy: Hey there!

Meg Talikoff: Hi Megan!

Megan Hall: So, before we talk about this other mystery disease, can we go over how ticks spread illness in general?

Meg Talikoff: Sure! Let’s hear it from Dr. Thomas Mather, a professor at The University of Rhode Island  who is one of the most recognized tick experts in the country.

Thomas Mather: When a tick feeds, it doesn’t just suck, it spits and sucks. And when they initially spit, they secrete a cement substance so that they’re stuck in your skin.

Nat Hardy: While they’re there, they transfer everything in their saliva into our blood. Including their diseases.

Megan Hall: And that’s how we get infections like Lyme Disease?

Nat Hardy: Exactly.

Megan Hall: So, what’s the deal with this other sickness?

Meg Talikoff: You’re talking about alpha-gal syndrome. That’s alpha as in Alpha Male, and gal as in gal pal.

Nat Hardy: It’s kind of a cool name. But everything else about it is terrible.

Meg Talikoff: First off, it’s not a bacteria or a virus, it’s an allergy.

Nat Hardy: If a tick with alpha-gal bites you it can make you allergic to a specific type of sugar called alpha-gal. And that sugar is found in most products that come from mammals..

Megan Hall: So a tick bite could make you allergic to meat or cheese?

Nat Hardy: Exactly.

Megan Hall: And how seriously allergic? Is it a headache situation or is it dangerous?

Meg Talikoff: It varies from person to person. But often it’s extremely serious. A lot of people learn that they have alpha-gal syndrome when they go into allergic shock.

Nat Hardy: One scary thing is that it doesn’t kick in right away. You eat red meat, and you feel fine. But then a few hours later, your body freaks out.

Meg Talikoff: Stephanie Turner from Bristol, Rhode Island had her first serious alpha-gal experience in 2018.

Stephanie Turner: On June 7th, I had a steak salad. And I woke up at 3 am. I had like a histamine rush, so I could feel this heat just go *woosh* and then I was just broken out in hives, and getting sick to my stomach. I woke up my husband, at three in the morning, and I honestly was like, I can’t breathe.

Megan Hall: That’s terrifying. Is she okay now?

Nat Hardy: She’s figured out how to stay safe. But alpha-gal really changed her life.

Meg Talikoff: Going out to eat can be nearly impossible for her.

Stephanie Turner: When I get a chicken bahn mi, and it says chicken pâté, it doesn’t say chicken pâté made with pork fat.

Nat Hardy: She was also a huge traveler before her diagnosis.

Stephanie Turner: It absolutely breaks my heart that I will not be able to experience a culture through their food.

Meg Talikoff: She has to cook separate meals for her family and herself every night. And she’s learned the hard way that mammal products are in things you’d never think of.

Nat Hardy: Like, people use bone char to filter sugar. And there are mammal products in all sorts of over the counter medicines.

Megan Hall: Wow. I can’t believe I hadn’t heard of alpha-gal. Is it rare?

Meg Talikoff: For a long time, it was. Now, not as much.

Megan Hall: Why?

Nat Hardy: Alpha-gal is spread by lone star ticks. And lone star ticks didn’t used to be that common in New England.

Meg Talikoff: In Rhode Island, they were mostly confined to a small and isolated place called Prudence Island.

Megan Hall: So what changed?

Nat Hardy: Thomas thinks it’s all about deer.

Thomas Mather: All of the types of ticks that are increasing, rely on white tailed deer as a reproductive host.

Meg Talikoff: And so as deer became more common throughout Rhode Island, Lone star ticks have moved from Prudence Island to the mainland, too.

Megan Hall: So what do we do?

Nat Hardy: The same stuff you do to prevent Lyme disease. Do daily tick checks, don’t walk through tall grass.

Meg Talikoff: And consider spraying your clothes with a tick repellent called permethrin. It lasts through 70 rounds of laundry and it really works.

Nat Hardy: If you do get bitten by a tick, you can send a picture of it to Thomas’s lab. Just look up URI TickSpotters.

Meg Talikoff: An expert will tell you what type of tick it is, and what the best next step is for you.

Megan Hall:Thanks, Meg and Nat!

Students at the Lincoln School have a question: should they be using wooden pencils or plastic mechanical ones? This week on Possibly we explain the answer, and how to find it.

Megan Hall: Welcome to Possibly, where we take on huge problems like the future of our planet and break them down into small questions with unexpected answers. I’m Megan Hall.

Today, we’re tackling a question from some students at the Lincoln School: is a wooden pencil or a mechanical pencil better for the climate? Meg Talikoff and Nat Hardy checked it out for us.

Hey, guys!

Meg Talikoff: Hi!

Nat Hardy: Hey Megan!

Megan Hall: So, wood pencils versus mechanical ones. Which type creates less emissions?

Meg Talikoff: First, we have to kind of simplify the problem. We’re just going to compare a chunk of wood to a chunk of plastic.

Nat Hardy: That’s not crazy, because mechanical and wooden pencils are basically the same except for the main material that they’re made of.

Meg Talikoff: It’s also as good as we can do, because the way that companies turn plastic and wood into pencils is actually secret information that they don’t want to share.

Megan Hall: Okay, so this is more of a wood versus plastic fight. I instinctively want to say plastic creates more emissions. Is that true?

Meg Talikoff: To figure that out, we have to use something called a life cycle assessment.

Megan Hall: What’s that?

Nat Hardy: It’s a super detailed process that scientists use to analyze the climate impacts of every stage of a product’s existence, from the materials it’s made of, to its time in the landfill.

Meg Talikoff: Whatever you’re imagining, it’s probably five times more meticulous. To look at the impacts of a pencil, you have to know what type of fertilizer was used on the forest where it grew.

Nat Hardy: And how the factory powered its log-debarking machine.

Meg Talikoff: And how long it traveled to the store where you bought it.

Nat Hardy: And how much the wood will decay in the landfill depending on how much oxygen it touches.

Megan Hall: So you guys didn’t try to do this yourself, did you?

Meg Talikoff: No, luckily there were life cycle assessments out there already. And here’s what we found.

Nat Hardy: First, the type of energy used to make the material really matters.

Megan Hall: In what way?

Meg Talikoff: Well, if you think about it, what does it take to turn a living, standing tree into a pencil? A lot of different active steps. And all of those steps require energy.

Nat Hardy: You need to create enough energy to turn oil into plastic or trees into lumber. And since we’re not all using solar power, making energy creates emissions.

Marieke Head: Looking specifically at pencils, that’s probably where we’re going to see a lot of the emissions taking place in terms of the whole life cycle, so that’ll be in the manufacturing process itself.

Meg Talikoff: That’s Dr. Marieke Head, a scientist at a Canadian environmental consulting company named Groupe AGÉCO. She does life cycle assessments for a living.

Megan Hall: Okay. So, does that mean the most important thing is whether a pencil factory uses coal or solar?

Nat Hardy: It’s not the only factor, but you’re right. The type of energy a manufacturer uses is super important.

Meg Talikoff: For wood products, almost all of the emissions come from energy use. You could actually get  down to almost zero emissions if you used renewable energy in the manufacturing process.

Nat Hardy: Plastic is a little different, because the process for making it creates greenhouse gas emissions.

Meg Talikoff: But switching to renewable energy would still cut production emissions by around 60%. 

Nat Hardy: And either option could definitely win depending on who is and isn’t using renewable energy.

Megan Hall: So is the answer that there’s…no answer? We just can’t know?

Meg Talikoff: Technically yes. But there is one important thing about wood that makes it a better choice in a lot of cases.

Megan Hall: What’s that?

Meg Talikoff: Unlike plastic, wood can sometimes be considered a carbon-negative material.

Nat Hardy: That’s because trees absorb carbon dioxide from the air. And then wood doesn’t decay very much in the landfill. So a significant amount of the wood we throw away just becomes a carbon sink.

Meg Talikoff: Marieke looked at the emissions associated with processing lumber from Canadian forests. She found that those emissions were usually outweighed by the carbon dioxide the trees absorbed.

Nat Hardy: So as long as the wood comes from a forest that’s sustainably managed, wooden pencils might be the way to go.

Meg Talikoff: To find out if a pencil came from a sustainably managed forest, you can look for pencils that are certified by the Forest Stewardship Council.

Nat Hardy: But if you want to use a mechanical pencil, that’s fine too. Just refill it as many times as you can to keep its impact as low as possible.

Megan Hall: Sounds good!
