← The Great Pacific Garbage Patch

What is it made of?

Almost all of it is polyethylene and polypropylene, the light plastics in bottle caps, crates, ropes and nets. Count the pieces and it is nearly all tiny fragments. Weigh it and half is lost fishing gear.

Count it, then weigh it

The same 1.1 million pieces from the survey nets tell two very different stories. Flip between them.

What kind of plastic, by number of pieces

How big the pieces are, by number of pieces

9 in 10

pieces are smaller than a grain of rice

These microplastics, under 5 mm, are 93% of the pieces but less than 1% of the weight.

Over half

the weight is in big objects

Items longer than 50 cm, mostly bundles of net, are just 1 in 1,700 pieces but 56% of the weight.

Sunlight

breaks big things into small things

UV light makes plastic brittle and waves crack it apart. It doesn't disappear; today's crate becomes tomorrow's fragments.

Writing from all around the Pacific

Language printed on 382 recovered objects. Much of it is fishing and shipping gear, so the language shows where an item was made, not who dropped it.
