By now we're all aware of how damaging plastics are to our health, via the spread of microplastics in water. These particles are everywhere in nature now, and showing up in ever greater quantities in our bodies.

Surprisingly, this issue isn't being treated with more urgency. Perhaps because we've yet to find a truly horrifying example of what they'll do to humans. Recent research suggests they can cross the blood-brain barrier in human brains - perhaps something like that will be the wake-up call? Meanwhile, it's good to know people are working on alternatives.
