“These little particles are already seeping everywhere, and even into our organs.”
In question the PET bottles but also our synthetic clothes or the contact lenses… This omnipresence of plastic in our environment represents a danger for our health. This can have consequences for the immune system and the respiratory system, and can cause endocrine disruption, reduced fertility and an increased risk of cancer.
Why?
The most toxic plastics are those found in food products because the toxic constituents of the plastic end up mixing with the food. For example, bisphenol A, very present in our lives because it is part of the composition of the plastic that lines the inside of certain cans and cans, but also in that of receipts and banknotes, has been classified since 2017 by the European Chemicals Agency (ECHA) among “Substances of very high concern” as endocrine disruptor.
Many plasticizers and chemical additives are used in the manufacture of plastic to give it certain characteristics such as color or transparency, flexibility or rigidity, impermeability to light or to oxygen, flame retardants, etc. It is these additives that make plastics toxic.
Finally, the degradation, recycling or elimination stage is also at risk. Plastic waste can be degraded by incineration, recycling or landfill. When processed in an incineration plant, many toxic substances are released into the surrounding environment.

The most effective and inexpensive way to combat these dangers is to reduce production and limit the use of plastic items.
