Is it true that we consume up to a credit card’s worth of plastic every week?

This claim is certainly false. It misrepresents the state of scientific research. It is true that plastics have been found in the human body. Microplastics can be ingested or inhaled. However, the average quantity of plastic which enters the human body is unclear. Scientific estimates still differ strongly, however there is no doubt that ‘one credit card per week’ is a gross overestimate. Other studies estimate that humans eat less than the equivalent of a grain of salt per week, and that it would take several thousand years to consume the weight of a plastic bank card.
