And yes, those plastic bags will disappear in well until a few million years. I'm guessing we will start having trouble with plastic "rotting" in my lifetime.

BUT paper bags don't produce trash problems, because they break down quickly when they get wet. So no whale is going to choke on a plastic bag. If they get tangled in trees or fences, they will degrade, and fall down on their own. And they rot pretty quickly today -- no bacterial evolution needed.
Paper bags also hold more than plastic ones and are usually (around 80%) made from a traditional lumber mills waste stream.
