How does plastic get so deep in the ocean?

Plastic sinks. Systems fail.

The blunt answer
Plastic reaches the deep ocean because the sea is not a tidy blue surface. It is movement, pressure, currents, storms, animals, sediment and time.
10:02Translation: away is not a place. It is just a delay with worse lighting.
10:03Some plastic floats first. Some sinks quickly. Some grows a film of tiny sea life and grime, gets heavier, breaks up, or gets carried down.
10:04The scandal is not that plastic travels. The scandal is that disposable things were designed for a world with no real away.
How it gets down there
Poor collection, litter, rainwater running off streets, lost fishing gear, blown packaging, bins left open in silly weather. It is logistics failing in public.
10:09Official ocean-debris guidance says plastic can reach water through poor disposal access, weak collection, littering and rainwater washing rubbish along.
10:10And the deep ocean is not too remote to notice. Expeditions have found plastic, metal and glass in deep tropical Atlantic and Caribbean waters.
10:11A Japanese deep-sea database says the same thing another way: single-use plastic has been recorded even on remote deep seafloor.
10:12What people get wrong
People picture ocean plastic as bottles bobbing about like terrible little boats.
10:17Some does float. But tiny plastic pieces have been found from the sea surface to the mud on the ocean floor. Surface clean-ups matter, but they are not the whole job.
10:18So the grown-up answer is prevention. Less needless plastic. Better bins. Better collection. Better product design. Less magical thinking.
10:19Where Generation earth fits
Generation earth's view is simple: a disposable product should have a narrow job and an honest end-of-life route. If it does not, the ocean becomes storage.
10:25A food-waste caddy liner should be boringly good. Fit the caddy. Hold the mess. Tie properly. Then go through the right food-waste or composting route.
10:26Compostable does not mean ocean-safe. It means the product needs the right composting conditions, the right proof and the right disposal route. Start with the caddy liner range.
