In cosmetics, we refer to very small particles that are very common in some of the cleansing gels and exfoliants that we can find in the market.
What is the problem with them? These particles travel through the sewer system with the water that comes from the shower. They are so small that in purifying plants, they cannot be separated from water, so they flow into the oceans to form part of the great "Plastic Soup".
Once the microparticles are in the oceans of the whole world, any fish or animal could (and surely will) ingest particles that are hardly detectable to the human eye. Then, the plastic particles enter the food chain, causing potential damage to any animal that is above in the food chain.
From "Beat the microbead" they are fighting this problem through a mobile application launched in Netherland by the North Sea Foundation and the Plastic Soup Foundation.
