Two thoughts just collided in my head.

One:  The crisis of China not wanting our trash any more. We haven't actually been recycling stuff, just selling it to someone else.  Millions of tons of it.

Two: The crisis of landfills filling up.  If you think about it, this translates to "We're running out of holes in the ground." 

Collision results:

If our trash is worth shipping to the other side of the planet, it's worth shipping somewhere closer. 

Like, some place that still has holes in the ground. 

So we can put the carbon back in the ground where it came from.

EXACTLY where it came from.

Commentary:  I don't know if I'm brilliant or stupid this morning.  I'll finish my coffee now.
