Between 40,000 and 110,000 metric tons of plastic from Americans end up in the ocean every year, according to a study in Science last year. Researchers said the plastic waste frequently comes from coastal areas - but some also makes its way through inland waterways to the ocean.

Plastic can become stuck in sea animals' bodies along with toxic chemicals and bacteria absorbed by the material.
"We ideated, designed, prototyped and manufactured Edible Six Pack Rings," according to We Believers, a NY-based ad agency that partnered with the brewery on the project. "A six-pack packaging design that instead of killing animals, feeds them."
And while it's not clear that you'd want to encourage sea animals to eat beer packaging - biodegradable or otherwise - if this packaging does make it to sea, at least it's possible it will dissolve or can be consumed.
