The global trade in plastic waste reveals stark inequalities. For decades, high-income countries like the UK, US, Germany and Japan exported much of their plastic waste to lower-income nationals, often with weak waste infrastructures (OECD 2022, Plastics Treaty Briefing 2023). This practice, often referred to as “waste colonialism,” offloads the environmental burden of consumption onto those least able to manage it. As recently as 2018, Asia imported 70-80% of the world’s tr

The idea that plastic will outweigh fish in the ocean by 2050 has become one of the most widely-quoted statistics in environmental discussions. But this disguises the real nature of the problem. Fish make up around 29% of animal biomass on this planet (Ritchie 2024) but calculating their mass in oceans is very difficult. We can estimate algae concentrations from satellite imagery - a proxy for fish food - but actual marine biomass remains uncertain and rather variable. Est

If there’s one thing to take away from the United Nations Ocean Conference (UNOC 2025) and the ocean plastics crisis, it’s that solutions do exist, but that they’re not scaling, not enforced and not shared equally. Cleanup technology may help in pollution hotspot areas, but they treat symptoms, not causes and are cost intensive. Recycling has a role, but its effectiveness is vastly overstated and most plastics are actually not recyclable to date. Individual actions - whilst

The 2025 United Nations Ocean Conference (UNOC) brought ocean issues back into the global spotlight. Delegates from over 100 countries convened to reaffirm commitments to SDG 14: Life Below Water, address overfishing and clamp down on marine pollution. The tone was urgent, the diversity of stakeholders impressive and the pledges ambitious - but the gap between promises and action remains as wide as ever, with a clear lack of dedicated funding to prevent plastic and microplast

In 2016, headlines proclaimed that by 2050, plastic in the ocean could outweigh fish. The science behind this claim is weak - estimating biomass is notoriously difficult - but the message is no less important. The real issue isn’t a race between fish and plastic. It’s the failure of governments, industries and global systems to prevent known harm. At the 2025 UN Ocean Conference (UNOC), governments once again pledged action on marine pollution. But critics, including ClientEa

Plastic pollution has become one of the most critical and urgent threats to ocean health, affecting marine ecosystems from the surface to the deepest seabed through biological and chemical impacts at both macro- and microscales. Each year, an estimated 8 to 11 million metric tonnes of plastic enter marine environments, where they persist for decades to centuries and continuously interact with seawater, organisms, and sediments. At the macroscale, large plastic debris, such as

Microplastic pollution has become a major environmental concern, receiving growing interest from scientists, policymakers, and the general public. While much attention has been given to the persistence and toxicity of plastics themselves, research has more recently suggested that microplastics may pose an additional and less visible risk: they can act as carriers for microorganisms, including potentially harmful pathogens. Once in the natural environment, microplastics are ra

Over the past decades, ocean plastic pollution has become one of the most urgent global environmental challenges. Plastics continue to enter marine environments through a variety of pathways, accumulate and persist for long time periods in many different forms, from large items to microscopic fragments that are integrated into ecosystems and food chains. Most of the plastic entering the ocean originates on land. Mismanaged waste, especially single-use plastics such as packagi
