Scientists have found traces of microplastic in the digestive tract of some of the most isolated animals in the world. Visiting the King George Island in Antarctica, researchers found contamination in the gut of tiny creatures, often called springtails, that live on Antarctic soil. The findings published in the journal Biology Letters put other animals including seals, sharks and penguins at high risk. The lead author told CNN that they think that the creatures must have ingested plastic while eating the algae, moss and lichen coating a polystyrene block that found littering the coldest place on earth. The team also warned that microplastics can carry pathogens and contaminants making the findings more worrisome.
