Okay, serious question: how much carbon is sequestered in plastic if we toss it in a landfill? Given that there's a finite amount of oil left in the world, and that it gets more expensive as supplies dwindle, I almost wonder if using more disposable plastics helps the fight against climate change. Better to turn the carbon into a solid and bury it than burn it and put the CO2 in the atmosphere, right?

The core problem with this is finding the land to fill. It's not as simple as any ole hole, the stuff is a low-grade contaminant that oozes nasties over decades. For the huge bulk of plastic waste that's a lot.

Better by far would be local recycling instead ; this is a fine thing for a government incentive as the (arbitrary, fickle) market incentive has gone away.

Not a direct answer, but 4% of global oil production goes to plastics, so I'd put the ceiling slightly higher.

4% does not seem a big enough slice of the carbon puzzle pie to really make a huge difference compared to something like fuels. seems like we should just focus on a solution that minimizes local and immediate human suffering.
