The problem is "Too Much Sand!"

I heard the funniest thing on the radio this morning. Martin Devlin on Radio Live said (although HE may have been quoting somebody else!) that:

What have all the trouble spots in the world got in common?

Answer: An abundance of SAND!
Iran, Iraq, Libya, Palestine, Israel

Solution: Cover the world in CONCRETE for world Peace!

Of course, this was all said in jest, but is there a link between the abundance of SAND, and CIVILISATION (or covering the world in concrete!). ie progress, property rights, capitalism, development etc etc - I don't know - just a thought.

He did go on to add Whitianga, and Mount Maunganui for their riots on New Years Eve, and several sandy Australian hot spots.
