Marine Plastic Pollution: Other Than Microplastic
AI summary Read the abstract
This paper reviews the sources, distribution, ecological impacts, and management challenges of macroplastic (plastic larger than 5 mm) in marine environments, arguing that macroplastics deserve more attention despite being overshadowed by microplastic research. Macroplastics are the precursors to microplastics and pose direct physical hazards to marine wildlife through entanglement and ingestion.
Marine litter is a growing environmental problem and plastic, the largest component of litter, is now widely reported within the marine environment. Macroplastic (plastic larger than 5 mm) may be perceived as one of the most concerning forms of plastic pollution due to its high visibility. However, it is also a major contributor to microplastic due to its fragmentation. The majority of this plastic debris originates from land and once released into the marine environment it has the potential to become widely dispersed via wind and currents. It then poses threats to the environment, the economy, and human well-being on a global scale. These potential threats presented by plastic debris have been identified as a major global conservation issue and a key priority for research. Understanding the sources and implementing policies to reduce the amount of plastic waste produced is required for effective long-term change.
