Plastic pollution accumulating in an area of the environment is considered “poorly reversible” if natural mineralization processes occurring there are slow and engineered remediation solutions are improbable. Should negative outcomes in these areas arise as a consequence of plastic pollution, they will be practically irreversible. Potential impacts from poorly reversible plastic pollution include changes to carbon and nutrient cycles; habitat changes within soils, sediments, and aquatic… 
Plastic pollution in the Arctic
Plastic pollution is now pervasive in the Arctic, even in areas with no apparent human activity, such as the deep seafloor. In this Review, we describe the sources and impacts of Arctic plastic
Birds and plastic pollution: recent advances
It is identified that human commensal birds, long-life-span birds, and model bird species could be utilized to different research objectives to evaluate plastic pollution burden and toxicological effects of chronic plastic exposure.
Can we quantify the aquatic environmental plastic load from aquaculture?
Managing Watersheds for Coral Reefs and Public Health: A Vibrant Oceans Initiative Whitepaper
The health and integrity of coral reef ecosystems are in decline worldwide due to an increasing suite of human activities, which threaten biodiversity and human wellbeing. One of the major drivers of
Achieving net-zero greenhouse gas emission plastics by a circular carbon economy
A bottom-up model that represents the life cycle of 90% of global plastics is developed and shows that net-zero emission plastics can be achieved by combining biomass and carbon dioxide utilization with an effective recycling rate of 70% while saving 34 to 53% of energy.
Photocatalytic Conversion of Plastic Waste: From Photodegradation to Photosynthesis
Plastic waste remains a global challenge due to the massive amounts being produced without satisfactory treatment technologies for recycling and upcycling. Photocatalytic processes are emerging as


Predicted growth in plastic waste exceeds efforts to mitigate plastic pollution
Assessment of three broad management strategies, plastic waste reduction, waste management, and environmental recovery, at different levels of effort to estimate plastic emissions to 2030 for 173 countries found that 19 to 23 million metric tons, or 11%, of plastic waste generated globally in 2016 entered aquatic ecosystems.
The Global Plastic Toxicity Debt
There is a toxicity debt that is incurred by having large amounts of plastic currently in the environment, exposed to degradation, but that has many more years of decay and release of toxic compounds to follow, and this debt is called toxicity debt.
Evaluating scenarios toward zero plastic pollution
To avoid a massive build-up of plastic in the environment, coordinated global action is urgently needed to reduce plastic consumption; increase rates of reuse, waste collection, and recycling; expand safe disposal systems; and accelerate innovation in the plastic value chain.
Reducing Uncertainty and Confronting Ignorance about the Possible Impacts of Weathering Plastic in the Marine Environment
Plastic in the global oceans fulfills two of the three conditions for pollution to pose a planetary boundary threat because it is causing planetary-scale exposure that is not readily reversible.
