I think getting away from plastic--when we can--makes a lot of sense. It's a marvelous invention for things that need to have its special properties and also last a long time. For throwaways, I prefer paper and paperlike materials, although I know paper manufacture is not an environmental free ride, either. But isn't most plastic mainly made of oil? (NOT a rhetorical question...). And nobody really seems to know how long a plastic object is with us... Even the dangerous life of radioactive waste can at least be calculated!
(Paper cases smell better, too).
Just my retro thoughts.
