Microplastics can interfere with the small organisms and sinking particles that help move carbon into the deep ocean. Laboratory studies have measured changes in plankton feeding and the descent of carbon-rich material; computer models have explored the possible consequences for ocean carbon storage.
These findings establish plausible mechanisms for weakening the biological carbon pump. They do not establish a measured global decline caused by microplastics. The distinction…
