Peak Phosphorus, and Why It Matters

I guess that peak oil is like the tip of the iceberg...

It is to be expected... all of us in the developing countries would like to consume like the U.S, and according to a persistent useless factoid, we would need 5 Earths to sustain that: http://www.useless.org/node/70

OTOH the article sounds a bit alarmist "humanity faces a Malthusian trap of widespread famine on a scale that we have not yet experienced" - is the source reliable, yellow journalism or what?

So the obesity problem is solved then?
