New research shows that plastic has collected in a region of the Atlantic as well, held hostage by converging currents, called gyres, to form a swirling “plastic soup.” And those fragments of plastic could also be present at the other three large gyres in the world’s oceans, says Kara Lavender Law, a member of the oceanography faculty at the Sea Education Association (SEA) in Woods Hole, Mass., which conducted the study.

Because the plastic has broken down into tiny pieces, it is virtually impossible to recover, meaning that it has essentially become a permanent part of the ecosystem. The full impact of its presence there – what happens if fish and other marine animals eat the plastic, which attracts toxins that could enter the food chain –  is still unclear.
