Glitter is festive and fun – a favourite for decorations, makeup and art projects. But while it may look harmless, beautiful even, glitter’s sparkle hides a darker side. Those shimmering specks often end up far from party tables and greeting cards. You can even spot them glinting on beaches, washed in with the tide.
In our recent research, we discovered that glitter – specifically, the kind made from a common plastic polymer called polyethylene terephthalate (PET) – is not merely polluting the ocean. It could actively interfere with marine life as it forms shells and skeletons, which is a much bigger deal than it might sound.
Put simply: glitter helps the formation of crystals that nature did not plan for. And those crystals can break the glitter into even smaller pieces, making the pollution problem worse and more long-lasting.
