Well once we get the world economy sorted out and settled down we can start worrying about The Next Big Thing, which, according to the BBC is Phosphorus Depletion!
Forget about Oil, it's Phosphorus that we need to worry about.
I think my grandfather was a guano dealer. He imported it from islands
off Chile and sold it to farmers and gardeners for fertilizer.
I think that today the seagull shit islands are quite depleted.
The prized ingredient in seagull shit is -- yes -- Phosphorus. I can't
quite see how the world could lose all its available Phosphorus,
but let's hope it doesn't happen
because it is Phosphorus, hopping off and on adenosine
molecules that is the true Meaning of Life.
That's how we get our energy.

It's nice to know that some people, somewhere, are actually
evaluating how long we can
plunder the earth
without a thought.
