"But is it really true that they are not bio-dedgradable?"

Well, many plastics are pretty stable molecules. And they aren't normally occurring ones, so the present bacterial populations haven't evolved to use them. Now, as the percentage of the plastics increase in the environment, sooner or later something will develop to utilize them.

But, then the other part of the problem crops up. Plastics generally don't have much in the way of oxygen in their composition. So to fully degrade them, some oxygen is going to be required. The problem is that unless we just chunk our trash on the side of the road, they are put in landfills. Which don't have much in the way of available oxygen.
