Plastic pollution in Okinawa coral reefs

Overview

Researchers in Okinawa, Japan, have identified a new form of marine pollution termed ‘plasticorals’. This phenomenon involves melted polymers from common household plastics, such as polyethylene and polypropylene, becoming permanently fused with the porous skeletons of dead coral.

Initial findings from the Okinawa Institute of Science and Technology and the University of Ryukyu describe these as a type of plastiglomerate where melted plastics penetrate coral pores to create an inseparable bond. Scientists suspect that heat from beach fires may provide the necessary temperature to liquidize the plastic into the coral structures.

The discovery, which includes areas within the protected Yanbaru National Park, raises environmental concerns regarding habitat degradation, chemical leaching, and new mechanisms for microplastics to enter the marine ecosystem. Because the resulting debris can wash back into the sea, there are risks to reef functionality and the natural processes involving coral gravel and marine organisms.
