Microplastics

When you drizzle honey onto toast, you probably picture a clean product that came straight from a flower. The reality is a little stranger. A honeybee is basically a flying dust mop, and some of the dust it collects is plastic. Over a single season, a colony quietly records the plastic pollution drifting through its neighborhood — and a surprising amount of that record ends up in the jar.

Bees Are Accidental Air Samplers

Bees are covered in branched hairs that evolved to grab pollen. In flight, those hairs pick up a static charge, so they attract tiny particles the way a rubbed balloon attracts your hair. As National Geographic’s reporting on the topic describes, pollen, plant debris, wax, and even bits of other bees get caught this way. Airborne microplastics — plastic fragments and fibers smaller than 5 mm — get caught too.

The Hidden Environmental Cost of Cycling

While cycling is widely celebrated for its environmental benefits, recent scientific research has uncovered an unexpected environmental impact that even the most eco-conscious cyclists might not be aware of: microplastic pollution from bicycle tire wear.

A groundbreaking 2025 study from the University of Bayreuth has quantified for the first time the amount of microplastic particles released by mountain bike tires during real-world usage. The findings reveal that while bicycle tires do contribute to microplastic pollution, the scale is dramatically different from what we see with motor vehicles.
