Global drought

An article from Salon.com about the drought in the Southeast US, Europe, and Australia. The point the author writes, which I ask also, is why haven't we heard about this? Why is the mainstream media not covering this? And why aren't they asking and trying to answer the question: What happens when the water runs out? Especially as Atlanta is said to have 80-120 days of water left.

This will mostly affect the poor if widespread migrations start. Not in other countries but here in America. What if Atlanta becomes another New Orleans? And other cities follow. This is the kind of thing that history books record as ending empires.
