What are microplastics?

What are microplastics? Thanks for asking! There are tiny fragments of plastic pretty much everywhere in the ocean, in the ground and inside animals, including humans! These are known as microplastics, and their potential impact on human health and the environment is a cause for concern. Microplastics aren’t a specific type of plastic per se. The term is used to refer to any fragments which are under 5 mm in length. Some examples are polystyrene, polypropylene, polythene and a bunch of other poly-things. They come from large plastic objects, like cosmetics or synthetic fabrics in clothing.  Where are microplastics spreading the most? The obvious example is on ocean floors, where scientists have estimated there are 14 million tonnes of microplastics. Every minute, we fill the oceans with the equivalent of a garbage truck full of plastic. And then you’ve got microplastic pollution in soils. That causes damage to creatures like mites and larvae which maintain land fertility. There must be some protected locations out there, surely? What about in the mountains or at the North Pole?
