Microplastics almost universally found in marine mammals

Researchers are consistently finding microplastics inside marine mammals such as whales, dolphins, and seals, according to a first-of-its-kind review of the scientific literature. Of the 30 studies reviewed, only one did not report finding microplastics inside one of these animals. Additionally, eight out of ten studies looking specifically at seals also reported finding differing amounts of microplastics in their faeces. The authors say the next step is to research the impact of microplastics on the health of marine mammals.
