I edited a paper about the ecological impact and human health risks of microplastics in aquaculture ecosystems. My daughter is currently doing microplastics research at Eckerd University, so it was a rare instance where I had a personal interest in the subject matter. During my subsequent trip down the wormhole, I learned that each time you use a microbead-containing facial or body wash (which, for years, has been most of them), up to 94,000 plastic microbes can be flushed down the drain - each time.
