Review finds plastic pollution qualifies as planetary boundary threat
Review in Environmental Science and Technology presents evidence that plastic pollution fulfills all three criteria necessary for consideration as a planetary boundary threat: global exposure, not easily reversible, creating hazards disrupting earth system processes; suggests research priorities to find extent of planetary boundary but states risk that “boundary threshold for environmental plastics could be crossed before it is known”
