Marine plastic in numbers: what really ends up in the ocean
Published · 8 min read · Paul Kasten
Marine plastic is the most-discussed environmental story of the past decade, and the least understood. Here are the numbers that matter, clearly placed in context.
How much plastic enters the sea each year?
Credible estimates range from 8 to 12 million tonnes a year. That is one truckload. Every minute. The figure has barely moved in ten years, which means the countermeasures are not yet working at scale.
Where does the plastic come from?
Around 80% comes from land: rivers, landfills, wind, untreated wastewater. 20% comes from the sea itself, from fishing and shipping. In plain terms: ocean plastic is mostly a problem of how we handle waste on land.
Macro- vs. microplastic
What starts as a bag or bottle breaks into microplastic (<5mm) via UV and waves. Once that small, it is almost impossible to remove. That is exactly why every hour counts while it is still macroplastic we can collect.
What can one person do?
Changing your own consumption alone isn't enough. What truly moves the needle: a) pressure on companies and policy; b) funding the organizations that do the recovery. Point b) you can act on today. That is exactly what TaskBlue does: you buy a Focus Buoy once (29.99 or 39.99 euros), and a fixed share funds ongoing missions that pull plastic out of the sea.
Find your focus. Free the sea.
TaskBlue is free. With a Focus Buoy (one time from 29.99 EUR), every hour of deep focus pulls real plastic back to land.
