How one red thread led me to rethink microplastics, clothing, and natural fibers
Around 2003, I was working as an analyst in a pharmaceutical manufacturing facility. It was the kind of place where everything is controlled. Tyvek suits. Pressurized airlocks. Booties over shoes. A whole choreography to keep anything that doesn’t belong from getting into a vial of injectable medication.
One day, inspectors found a red fiber in a drug vial. You didn’t need to be a scientist to know it shouldn’t be there. But we still had to identify it.
The moment I saw it, I recognized it — a synthetic carpet fiber from the administrative side of the building. Testing confirmed it.
I couldn’t stop thinking about that tiny strand. If a plastic fiber could make its way through cleanrooms designed to keep contamination out, where else was it going? Where were all the other fibers from carpets and clothing and upholstery ending up?
I didn’t overhaul my life overnight, but over the years I kept coming back to that little red thread.
It was the beginning of a question I’m still following.
What Happens to All of It?
Plastics are everywhere in our daily lives — in our closets, our homes, even our gardens. And let’s be honest: they’re convenient. They’re often less expensive. They can be durable and easy to care for.
But over time, I started noticing something I hadn’t paid attention to before: plastics don’t just sit there. They wear. They shed. They break apart.
When plastic “breaks down,” it doesn’t return to soil. It becomes smaller and smaller pieces of plastic. Microplastics. That shedding happens when carpets age, when upholstery rubs, and even when we wash synthetic clothing — fleece jackets, athletic wear, anything containing polyester or acrylic.
Once I began looking into it, I was shocked. Researchers studying aquatic life began finding microplastics in nearly every species they examined.
We don’t yet know exactly what the long-term health effects are. Studying something so widespread is complicated — it’s difficult to even find comparison groups without exposure. It will take time, and many studies, to fully understand what this means.
In the meantime, these particles are simply too small for most filtration systems to catch.
It’s discouraging.
I don’t think the answer is panic, but we also can’t pretend it’s not happening.
A Better Way (Even If It’s Imperfect)
I haven’t eliminated plastic from my life. I doubt most of us can. It’s deeply woven into everyday modern life, and natural fiber alternatives aren’t always easy to find — or afford.
I learned that firsthand when I was pregnant and sweating my way through synthetic maternity clothes. At that time, natural fiber options were scarce — even expensive ones — and especially in maternity clothes.
Then, as my kids grew through piles of clothing, I saw it again. Nearly all contained at least some petroleum-based synthetic fiber.
At some point I found myself thinking: This isn’t working. It’s not that I believed I could fix the global textile industry. I just wanted better options.
I realized something simple and obvious: we won’t have access to natural fiber textiles unless there are still people producing natural fibers.
That realization is part of why I stepped back from pediatric research and started raising sheep.
My little farm isn’t going to save the world. But I do believe we can build better systems — slowly, imperfectly, practically. Here in the Pacific Northwest, those systems are beginning to grow.
In the weeks ahead, I want to explore what that might look like in our closets, our homes, and even our gardens. It’s not a lecture and perfection is definitely not the goal. It’s just a conversation about materials, and what happens to them after we’re done with them.
Is this something you think about?
What concerns you most?
What gives you hope?
I’d love to hear what you’re noticing, too.
