    Micro plastics form from all types of plastic very slowly. It a kind of shedding of the plastic as it breaks down but can also happen faster with abrasion.

    For example each time you use a toothbrush the plastic bristles shed micro plastics, or each time you open a plastic water bottle microplastics are released.

    When a plastic bottle ends up in the ocean it will circulate for a long time, releasing microplastics, and also slowly disintegrating into multiple peices.
