see it portrayed right there on your screen. gas is up 12% in the past month. oil is up quite a lot, especially when you look over the last year. the question is the unrest in libya, which produces about 2% of the world's oil and sits on the biggest oil reserve in africa, will that spread to much bigger producers like saudi arabia? another factor here at play is the situation in japan. japan nuclear power, for all intents and purposes, off line. what happens when you get to the recovery in japan? how much oil energy is that going to take? that's a big question right now. and i want to point out to you an interesting sur survey that we did at cnn.com. economists said two-thirds of all the economists we polled, we polled about 23% of them said oil prices are their single biggest concern, carol, when it comes to this broader economic recovery. every day when you spend more at the gas pump, you're not spending that the other things, so economists are very, very worried about this run up that we're seeing. >> poppy harlow, thanks.
