I like the fact that the plastic is biodegradable. But I'm not convinced about the "more sustainable" part of EarthFirst's claim for PLA film. How much oil did it take to grow the corn and process it into the bit of plastic? What ever happened to the old oatmeal boxes that were entirely cardboard with a bit of cotton string to open the box?
Oh, look. NatureWorks Polymer is a Cargill company. I'm trying to keep an open mind about this. But Cargill's going to have a really hard time convincing me their priority is protecting the environment rather than maximizing their profit.
