Sea salt around the world is contaminated by plastic. Microplastics found in sea salt from the US, Europe, and China. Americans that eat 2.3 grams of salt per day could be ingesting upwards of 660 particles of plastic each year. In Spain, 21 different types of table salt and all had plastic in them. The most common type of plastic they found was polyethylene terephthalate, the material used to make plastic bottles. Other research has found that 1million plastic bottles are purchased per minute, and that recycling efforts are failing to keep pace with production, which is expected to quadruple by 2050.
