Humanity is being driven ashore : a juridical and political essay on marine plastic pollution
Summary
This essay examines the legal and political dimensions of marine plastic pollution, reviewing international agreements and their limitations in curbing the flow of plastic waste into oceans. It argues that stronger global governance frameworks are needed to protect marine environments from plastic contamination.
Since its invention, in the 1950s, plastic can be found in almost every object or structure. It has created numerous opportunities in many fields, boosting markedly mankind’s development and even its life span. However, combined with modern consumption patterns, in a world that is more and more urban and technological, plastic amounts have reached proportions never seen before. Consequently, plastic waste quantities are also exceeding all the limits reached so far and it is ending in our oceans for two main reasons: reckless behaviour of consumers and improper waste management. National waste management systems worldwide are facing severe challenges, especially at the moments of collection and disposal. That happens particularly in Asia and the causes are lack of money and structures, and governments and citizens lack of interest. Marine plastic pollution has been affecting all humanity for several decades but only recently it has been recognised. Each year, at least eight million tonnes of plastics leak into the oceans. Its sources are numerous and can be land-based (80%) – dumps, littering, sewage, industrial activities – or sea-based (20%) – commercial fisheries and offshore oil and gas platforms. Ironically, the characteristics that make plastic so useful – lightness, durability, low cost and malleability – are the same that transform plastic in a long-term problem for the environment. Once in nature, plastics never disappear, they just disintegrate into smaller and smaller particles, while they quickly spread across all the geographic divisions and layers of the ocean. Plastics from all sizes can entangle marine animals and/or can be ingested by them, causing injuries, gut obstructions and death. Plastic waste is even responsible for heavy economic losses. Furthermore, microplastics are entering the human food chain and the consequences are unknown. Several existing legal instruments, of regional and international scope, are capable of addressing different aspects of marine litter. Some national initiatives are of utility as well. Nevertheless, few countries or regions have an overarching legal framework to tackle the problem. It is clear though that it is impossible to maintain the actual production and consumption patterns, and that is imperative to implement effective plastic waste management.

On the Challenge of Plastic Wastes and Litter in Oceans: Some Policy Reflections
This policy analysis discusses the growing crisis of plastic litter in the world's oceans, reviewing international agreements and national policies aimed at reducing ocean plastic pollution. The authors argue that current policy efforts fall far short of what is needed and propose stronger global governance frameworks.
Legal Approaches to Reduce Plastic Marine Pollution: Challenges and Global Governance
This review examined legal approaches to reducing marine plastic pollution and found that while international frameworks like the International Maritime Organization's MARPOL Annex V and regional agreements provide useful foundations, significant governance gaps and enforcement challenges remain in addressing the global scale of marine plastic contamination.
International Legal Systems in Tackling the Marine Plastic Pollution: A Critical Analysis of UNCLOS and MARPOL
This legal analysis examines how two major international agreements, UNCLOS and MARPOL, address marine plastic pollution and identifies significant gaps in their ability to reduce it. The existing laws lack enforceable requirements for reducing land-based plastic waste and have uneven enforcement of rules for ship-based discharges. The paper proposes strengthening international law to promote a circular economy approach, which matters because marine plastic breaks down into microplastics that enter the seafood supply.
An International Legal Framework for Marine Plastics Pollution
This legal analysis reviews the current international framework for regulating marine plastics and identifies significant gaps and inconsistencies across treaties and agreements. The chapter argues that stronger, more unified global legal instruments are needed to effectively reduce plastic pollution in the world's oceans.
Why we need an international agreement on marine plastic pollution
This commentary argues for the establishment of an international agreement to address marine plastic pollution, noting that plastic debris including microplastics is a pervasive global threat to marine biodiversity, ecosystem services, and potentially human health. The authors highlight that existing regulatory frameworks are insufficient to manage the transboundary nature of the problem. The study calls for measurable reduction targets and coordinated international action to curb the flow of plastic into the world's oceans.
