Apparently, Saudi Arabia is afraid that it is going to run out of sand. According to BBC.CO.UK (which, despite all appearances to the contrary, is also not a satire site) border checks have been set up to enforce a ban on sand exports.
This is from the same guys that claim they’re unable to stop terrorists from crossing the border into Iraq. I guess they’re short of manpower due to all those sand smugglers.
So even if we ARE able to kick our oil habit, we’ll still have to worry about sand embargos. In twenty years, some Democrat presidential hopeful will point out the 2003 invasion of Iraq, claiming that it was “all about sand.” (hat tip to Au Currant)
