breathing earth

Bet you can't not get sucked into this one. I don't think I really realized till I saw this that, a) the US has 300 million people compared to our 32, and b) we're the least densely populated country in the world? And we're a first world country? I don't get it. We've got room for everyone in Sierra Leone and Uganda and Serbia and... I'm embarassed to say there are quite a few countries I've actually never heard of. Lesotho? Benin? Moldova? Azerbaijan? Burkina Faso? Where have I been?
