Uh oh, that reference to plastic at the end there makes me wonder if we'll have a rubbish pile of graphene enhanced stuff spinning in the mid pacific in a few decades from now. I guess that'll break down to stuff edible to small and microscopic fish and other animals, but big chunks of it could still seem edible to large sea creatures like whales, and as far as I know the complications that causes are usually mechanical rather than chemical, so something as durable as graphene stuff could be even worse. I guess blending it in this that and everything else is going to make recycling stuff harder as well, if it's not hard enough already.
