Ocean Plastic Pollution
Quick Fact
By 2050, there could be more plastic in the ocean by weight than fish, if current trends continue.
This short film draws on Rowan Byrne's work with the Howth Seabin Initiative and his broader research into marine plastic pollution.
About This Species
Approximately 8 million tonnes of plastic enter the ocean every year. Plastic does not biodegrade — it breaks down into microplastics, tiny fragments that enter the food chain at every level, from zooplankton to whales. Marine animals mistake plastic for food, become entangled in plastic debris, and suffer internal injuries from ingested fragments. Microplastics have been found in the deepest ocean trenches, in Arctic sea ice, and in the bodies of marine mammals, fish, and seabirds worldwide.
Why It Matters
Plastic pollution is one of the most urgent threats to marine biodiversity. Addressing it requires changes in production, consumption, and waste management at a global scale.
Transcript
I've been diving for over 30 years. And in that time, I've watched the amount of plastic in the ocean go from a problem to a crisis. Every year, around 11 million tonnes of plastic enters the ocean. That's a rubbish truck every minute. By 2050, there could be more plastic in the sea than fish by weight. Plastic doesn't biodegrade. It breaks down into smaller and smaller fragments — microplastics — that now exist in every ocean on Earth. In the deepest trenches. In Arctic sea ice. In the bodies of fish, seabirds, whales, and sea turtles. I've found plastic inside leatherback turtles in Dominica. They mistake plastic bags for jellyfish — their primary food source. It blocks their digestive system and they starve. Microplastics absorb toxic chemicals from the surrounding water. When fish eat them, those toxins move up the food chain. They end up in the seafood on your plate. This is not a problem that will be solved by individuals picking up litter on beaches — though that matters. This requires systemic change. Bans on single-use plastics. Extended producer responsibility. Investment in waste management infrastructure in the countries where most ocean plastic originates. The ocean doesn't have a voice. We have to be that voice.
