  • Are plastics trapped in coral reefs?
  • These numbers suggest that large quantities of plastics may be trapped in the world’s coral reefs, probably acting as a global chronic stressor in already and increasingly damaged systems.
  • Where are plastics found in coral reefs?
  • Plastics were found in 77 out of 84 coral reefs surveyed in the Pacific, Atlantic and Indian oceans, including in deeper reefs and remote and near-pristine reefs, such as in uninhabited central Pacific atolls.
  • Is plastic pollution a threat to coral reefs?
  • The interactions between well-known global and local stressors for coral reefs are increasing 7, and as we have crossed the planetary boundary for pollutants 8, plastic pollution is emerging as a threat to many ecosystems, including coral reefs 3.
  • Why do coral reefs have a low plastic density?
  • Lastly, lower plastic densities in shallow reef waters may also reflect removal efforts by local reef stewards. Coral reefs provide food for hundreds of millions of people worldwide 20, 21, 22, which may explain the dominance of plastics originating from fisheries.
  • Why are coral reefs losing capacity to sustain their biological functions?
  • Coral reefs are losing the capacity to sustain their biological functions 1. In addition to other well-known stressors, such as climatic change and overfishing 1, plastic pollution is an emerging threat to coral reefs, spreading throughout reef food webs 2, and increasing disease transmission and structural damage to reef organisms 3.
  • Why do coral reefs resuspend?
  • For instance, shallow reefs are exposed to stronger wave energy, which could cause plastic debris to resuspend and be transported to coastlines and the open ocean, or to tumble down the reef slope and accumulate in deeper reef areas.
