The eighth issue of the Marine Environment Series published by the Regional Organization for the Protection of the Marine Environment (ROPME) addresses marine pollution caused by plastic waste as one of the most critical environmental challenges facing the world’s oceans, including the ROPME Sea Area. The report emphasizes that plastic pollution is more persistent and, in many ways, more hazardous than oil pollution due to its resistance to degradation and its long-term presence in the marine environment.
The publication highlights that approximately 80% of marine plastic pollution originates from land-based sources, particularly coastal human activities such as tourism, urban waste, and single-use plastics. Additional sources include fishing gear, industrial waste, and microplastics used in consumer products. Natural forces such as wind, rivers, and ocean currents play a major role in transporting these materials into marine ecosystems.
It also reviews the historical development and widespread use of plastics since the 20th century, leading to a dramatic increase in global plastic production and waste. While only a small fraction is recycled, the majority accumulates in the environment, especially in oceans.
The report details the accumulation and distribution of plastic waste in marine environments, where it constitutes a significant portion of marine debris found on the surface, seabed, and coastlines. It even forms large-scale accumulations known as the “seventh continent” or oceanic garbage patches. These pollutants severely impact marine life, causing entanglement, ingestion, starvation, toxicity, and death across a wide range of species.
Special attention is given to microplastics, which pose a heightened threat due to their small size, ease of ingestion, and ability to enter the food chain, ultimately reaching humans. These particles can also act as carriers for toxic chemicals and harmful microorganisms, raising concerns about ecological and human health impacts, including endocrine disruption and disease risks.
The publication further outlines the environmental and economic consequences of plastic pollution, including degradation of marine ecosystems and financial losses to fisheries and tourism industries, estimated at billions of dollars annually.
To address the issue, the report proposes several key mitigation measures, including:
Reducing the use of single-use plastics
Enhancing recycling and sustainable product design
Enforcing environmental regulations
Preventing waste disposal in marine environments
Promoting scientific research and environmental monitoring
Raising public awareness, especially among youth
Finally, the report underscores ROPME’s role in combating marine plastic pollution through regional agreements such as the Kuwait Convention (1978), environmental monitoring programs, awareness initiatives, and collaboration with member states.
It concludes by stressing that combating plastic pollution requires collective global action, integrating policy, science, and community engagement to safeguard marine ecosystems for present and future generations.
