Oil for plastic use just is not a CO2 issue, it has nothing to do with sequestration.

Oil for plastics is more akin to the use of any other natural resource in a product or good.

The above commenter indicated 'issues with extraction', well yes, but we have the same issues with extracting everything else. Also, frankly, most oil extraction is not very damaging directly - if we were only using oil for plastics, we'd probably only use the easiest to access oil, like from the Middle East where we pop a straw in the ground and that's it aside from refining.

Burned 'anything' that we put in landfills is actually better than raw garbage as it's considerably reduced and more dense - but it's still landfill.

We should strive for a solution that doesn't require landfill.
