I am both hopeful about and horrified at the prospect of enzymes that will break down plastics.
I'm hopeful because the man-made polymers that we have been creating and covering our world with for decades now are going to have to be broken down somehow, sometime. If decomposers are beginning to be able to process them into harmless - or even beneficial - products, that's great.
...but we have a lot of currently in-use polymers that we don't necessarily want to start breaking down into gray goo just yet.
...and if we find a way to make polymers break down more easily, will that just encourage us to make more of those polymers rather than stopping the production of them sooner?
