The problem
Millions of tonnes enter the ocean every year.
We treat that as a measurable, model-able problem — one with a source, a destination, and a solvable set of physics. The figures here are illustrative.
Where it accumulates
Rotating currents gather floating plastic into a handful of offshore zones. Select a zone for its profile.
North Pacific garbage patch
The largest offshore accumulation zone on Earth — a slow vortex of currents that gathers drifting plastic across an area several times the size of a mid-sized country.

Where it comes from
Most ocean plastic arrives through rivers — which is why intercepting it at the source is half the solution.

Why it matters
It doesn't disappear
Plastic fragments into ever-smaller pieces but never biodegrades — it persists in the ocean for centuries.
It enters the food web
Microplastics are ingested at every level of the marine food chain, with effects we're only beginning to quantify.
The curve is still rising
Without intervention, the mass of plastic entering the ocean is projected to keep climbing every single year.
