From Chris Blattman, I think, the Harvard Atlas of Economic Complexity, which purports to show the imports and exports of countries around the world. I say "purports" because I don't really understand it, except the link gives a graphic showing US exports by category in 2010. Major items are labeled, so "soybeans" is a nice gold block with ".87%" in its corner, which I assume means soybean exports accounts for that much of total exports. Fine and dandy. I get the idea.
But wait, down in the left hand corner there's this pinkish purple block which is labeled "Human or animal blood" and it's got "1%" in its corner.
Is Harvard really trying to tell me that we suck that much blood out of ourselves and our animals to ship off to whom? Blood is more valuable than soybeans? Where are the world's vampires who are importing that blood? Someone needs to get on this story, which has been totally unreported until now.
