ClearMarine debris: A review of impacts and global initiatives
This review provides a comprehensive overview of marine debris and its environmental, economic, and social impacts worldwide. Researchers found that plastics represent 50 to 90 percent of all marine debris, with millions of metric tonnes entering the oceans annually. The study surveys global policy initiatives aimed at reducing marine litter and identifies the need for more coordinated international action to address this pervasive pollution problem.

This UN Environment Programme report reviews the science on marine plastic debris and microplastics, identifies priority areas for action, and calls for improved waste management to reduce plastic flowing into oceans. It synthesizes existing research and provides policy recommendations for governments and industry.
Marine debris: A review of impacts and global initiatives
This review summarizes the global scale and impacts of marine debris, covering five main material categories and reviewing international cleanup and prevention initiatives. It highlights that plastic debris dominates marine litter and threatens wildlife, fisheries, and coastal communities.
Plastic pollution in the marine environment
This review provides a comprehensive overview of plastic pollution in coastal and marine environments, covering everything from how plastics enter the ocean to their effects on marine life. Researchers compiled global data showing microplastic concentrations ranging widely across different water bodies and sediments, with marine organisms accumulating significant amounts. The study underscores that plastic pollution causes ecological damage through entanglement, ingestion toxicity, and the transport of invasive species.
Assessment of Microplastic Impacts in the Marine Environment: A Review
This review summarizes the sources, environmental fate, and ecological impacts of microplastics in marine environments, covering impacts across food webs from phytoplankton to marine mammals. The authors identify key knowledge gaps and emphasize that biodiversity loss and food chain contamination are the most well-documented marine impacts. The review calls for integrated monitoring programs and international policy action to reduce plastic inputs to the ocean.
Plastics in Marine Environment
This review summarizes the growing problem of plastic debris in the marine environment, noting that over 700 marine species are affected and that microplastics can transfer pollutants up the food chain. It calls for stronger international policies and waste management improvements to address the crisis.
Marine debris: A review of impacts and global initiatives
This review summarizes the scale and impacts of marine debris globally, covering five main categories including plastics, and surveys international initiatives aimed at addressing the problem. Plastic is the dominant category of marine debris and is recognized as a growing threat to ecosystems and human communities worldwide.
Micro- and nano-plastics pollution in the marine environment: Progresses, drawbacks and future guidelines
This review summarizes the current state of micro- and nanoplastic pollution in the world's oceans, estimating that 50 to 75 trillion plastic particles are present in marine environments. The pollution threatens 17% of marine species and causes billions of dollars in economic losses, while also entering the human food chain through seafood consumption.
Impacts of plastic pollution in the oceans on marine species, biodiversity and ecosystems
This comprehensive report documented the extensive impacts of plastic pollution on marine species, biodiversity, and ecosystems worldwide, revealing a rapidly worsening situation that demands immediate international action to protect ocean health.
Micro Plastics in The Marine Environment: A Review of Their Effects on Marine Organisms and Ecosystems
This review examines the effects of microplastics on marine organisms and ecosystems, summarizing evidence for MP ingestion across trophic levels, physical and chemical harm to marine life, and the pathways through which marine MP pollution threatens biodiversity and fisheries.
Marine Plastic Pollution: Current Situation, Impacts, and Governance Strategies
This review examines the current state of marine plastic pollution, noting that approximately 8 million tons of plastic waste enters the ocean annually. The study discusses how plastics decompose and release toxic substances that harm marine life, and how plastic particles can enter the human food chain, while highlighting governance strategies and international efforts to address the problem.
Investigating the Influence of Microplastics on Marine Biodiversity and Human Health
This review paper examines the origins, prevalence, and impacts of microplastics on marine biodiversity and human health. The authors estimate that 51 trillion microplastic particles are present in marine ecosystems, where ingestion by organisms leads to nutrient deficiencies, toxicological effects, and bioaccumulation through the food chain. The study emphasizes the need for policy interventions focused on reducing plastic production, improving waste management, and enhancing public awareness.
The present and future of microplastic pollution in the marine environment
This review assessed the current and projected state of microplastic pollution in the marine environment, examining evidence on sources, accumulation trends, and biological effects and arguing that the problem will worsen without significant intervention.
The Effects of Ocean Plastic Pollution on Marine Ecology
This review describes how plastic waste accumulates in the oceans, breaks down into microplastics under sunlight and saltwater, and enters food chains as fish and shellfish mistake particles for food. It summarises the scale of the problem — plastic makes up roughly 70% of ocean pollutants and is linked to the deaths of millions of seabirds and marine animals annually. The paper serves as a broad overview of how ocean plastic pollution threatens marine ecology and, through seafood consumption, human health.
The Effects of Plastic and Microplastic Waste on the Marine Environment and the Ocean
This review summarizes the scale of plastic pollution in the world's oceans, where nearly 280 million tons of plastic are produced annually and much of it ends up in marine environments, affecting at least 267 species. Microplastics enter the marine food chain when sea creatures ingest them, ultimately reaching humans through seafood consumption, with potential health consequences that add to the economic and ecological damage.
Comments on marine litter in oceans, seas and beaches: Characteristics and impacts
This review examines the characteristics, sources, and ecological and economic impacts of marine litter across shorelines, pelagic zones, and benthic habitats globally, noting that approximately 80% of marine litter originates from land-based sources. Researchers discuss how marine litter degrades into microplastics over time and threatens both biodiversity and coastal tourism economies.
Microplastics in Marine and Coastal Ecosystems: Sources, Distribution, Ecological Impact, and Mitigation Prospects
This review chapter summarizes how microplastics enter marine and coastal environments—through runoff, maritime activity, and wastewater discharge—and documents their toxic effects on seabirds, marine mammals, turtles, and other wildlife. With annual global plastic production at 280 million tonnes and a substantial fraction reaching the ocean, the authors assess current mitigation strategies and their limitations.
Marine litter: trends and impacts in marine fauna
This review synthesizes evidence on marine litter sources, distribution, and ecological impacts, with particular focus on microplastics as a pervasive contaminant across all marine habitats. It finds that microplastics threaten marine life through ingestion, entanglement, and chemical transport, with impacts spanning trophic levels from plankton to large marine mammals.
