What problems remain unresolved when plastic has been buried in a landfill?

  At some point we will need a bacteria that can break down polypropylene/polyethylene chains. This will bring an end to plastics usefulness, but the alternative is going to be a continual buildup of inorganic molecules in the environment with unknown consequences.

    That's not quite what I meant. It does seem clear that the plastic littered throughout the environment is a problem. The bit that isn't obvious to me is why the plastic in landfills is a problem. The first step to picking a solution is understanding the problem, and I'm not there yet.
