plastic

Despite worldwide efforts to curtail plastic use — to ban plastic grocery bags, to switch to reusable water bottles instead of disposable plastic bottles, and to get rid of the microplastics in cosmetics, for example — we still produce more than 260 million tons of plastic each year. Almost a third of that plastic goes into disposable, one-time-use items. Only about 1 percent of it is recycled globally, so much ends up in landfills. Worse still, some of the plastic winds up in the world’s oceans.

Out in the middle of the northern Pacific Ocean, a giant floating mess of plastic debris is drifting and bobbing among the waves. Scientists call this expanse of litter, which stretches for hundreds of kilometers across open sea, the Great Pacific Garbage Patch. But before last summer, there was little information about how large the patch really is, what types of debris are out there and what kind of impact it is having on ocean life.
