The Great Pacific Garbage Patch, a rotating vortex of plastic debris, now spans three times the size of France, holding an estimated 1.8 trillion pieces of plastic. That number keeps climbing not because solutions don't exist, but because the industry responsible for managing plastic waste has little financial reason to shrink it. Since 1950, the world has produced 6300 million tonnes of plastic waste. Of that, roughly 9% has been recycled; the rest was incinerated, landfilled, or leaked into th

In 2022, UN member states passed a resolution titled ‘End Plastic Pollution’ and since then governments and corporations have been working on a number of global treaties and voluntary commitments to reduce their plastic footprints, with varying degrees of success.The Nice Ocean Action PlanThe United Nations Ocean Conference (UNOC) is a three-yearly formal UN summit. In June 2025, the third conference, UNOC3, took place in Nice, France. This resulted in the Nice Ocean Action Plan. This called for

The consequences of ocean plastic for marine life are devastating - and often invisible. While viral images of whales dying with bellies full of bags grab public attention, the broader damage runs much deeper. Over 100,000 marine mammals die each year due to plastic entanglement or ingestion (WWF 2021). At least 340 species have been recorded entangled in debris, especially fishing gear like nets and ropes. Once trapped, animals can suffocate, drown or suffer debilitating injuries. Marine birds

Plastic doesn’t get into the sea on its own. It travels there usually via leakage from poorly managed waste systems. Understanding this journey is key to shoring up these systems.Around 19 million tonnes of plastics leak into the environment on a yearly basis. Of this, around 14 million tonnes enters rivers, coasts and other water systems. An estimated 11 million tonnes then reach the ocean, which equates to around 0.5% of all global plastic waste.How does this happen?In many areas worldwide, ur

Perhaps you’re thinking oh - plastics aren’t my problem. Turtles getting trapped is sad, but I’m safe. You’d be wrong. The idea that plastic pollution only affects wildlife is a dangerous misconception. In reality, humans are part of the marine food web, and we’re already consuming the consequences of plastic waste. Microplastics - particles smaller than 5mm - are now found in 99% of seafood. Shrimp, mussels, fish and even sea salt have tested positive for plastic contamination. A 2022 study car

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 ClientEarth, argue that the o

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 microplastic pollution.The fin

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 valuable - won’t stop

Ocean plastic is often misunderstood - and misrepresented. Media images of massive garbage patches floating in the Pacific suggest the ocean is blanketed in rubbish. The reality is more complicated - and arguably more concerning. Of the 460 million tonnes of plastic produced annually around the globe (OECD 2022), 353 million tonnes go to waste and only about 9% is recycled in any meaningful way. Approximately 82 millions tonnes of this waste (of the 9%) is mismanaged - either littered, burned in

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. Estimating ocean plastic i

It is estimated that 11 million tonnes of plastic debris enter the oceans each year. Every year, the world produces over 400 million tonnes of plastic, and with recycling rates remaining below 10% globally, the volume entering our oceans continues to grow. Poor waste management and littering cause plastic to enter rivers and waterways, eventually pouring into the ocean. Discarded fishing gear is another major contributor.Once in the ocean, plastic is easily swept away by ocean currents, spreadin
