In a study published in May of 2022 by researchers from Vrije Universiteit Amsterdam and the Amsterdam University Medical Center, 80% of all the randomly chosen healthy volunteers tested positive for microplastics in their blood, including “polyethylene terephthalate, polyethylene and polymers of styrene (a sum parameter of polystyrene, expanded polystyrene, [and] acetonitrile butadiene styrene”[vii] Some of these can be traced to products used by humans, such as toothpaste and lip gloss, which have plastic in them, but there are also tremendous concentrations of microplastics in our water and air. Using data from 24 different expeditions around the world surveying plastic pollution, Marcus Eriksen of the Five Gyres Institute estimated there are 5.25 trillion pieces of plastic in the ocean.[viii] Microplastics have been found on the world’s highest mountain, Mount Everest, and the deepest depths of the ocean, the Mariana Trench, where deep-sea creatures have been found with plastic in their stomachs and sediment samples contained up to 2,200 plastic pieces per liter. [ix] In a 2019 National Geographic expedition, up to 119 microplastic particles were found per liter of water in samples of snow. It is clear human pollution is ubiquitous. Source: Human Pollution Isn’t Just Destroying Our Environment; New Studies Show It’s Slowly Killing Us | Tools of control
