Micro plastics and nano plastics
Many plastics in the oceans eventually break up into minute particles called micro plastics and nano plastics, which are absorbed into plankton which, in turn, is eaten by fish, which WE EAT. But there are micro plastics in the air that we breathe and even in the water that we drink! Many of the clothes that we wear are made using plastics and, as we wear them, micro particles break off and we breathe them! They can be seen, reflected as dust, when the Sun’s rays shine through a window in our own homes.
Micro plastics in our Food chain
The chart above demonstrates how plastic enters our food chain. It was found that currently humans ingest up to 11 000 pieces of plastic with seafood each year and that the amount is likely to rise up to 780 000 by the end of the century (The Telegraph, 2017) But seafood is not the only one source of micro plastics. Test revealed that 72% of tap water samples was contaminated with micro particles (The Guardian, 2017). Scientists discovered that micro plastics can also enter our blood stream and tissues. The same happens with cattle which drink water contaminated by micro particles. Absorbed by animals tissues they enter their blood stream and then are transported up the food chain when meat is consumed by people. Even vegetables when watered absorb some of the micro particles which then end up in our bodies.
