Gold fever is sweeping across South America and is at its most lethal in Colombia where it is fuelling the civil war. http://english.aljazeera.net/programmes/faultlines/2011/07/2011757127575176.html "if we are only thinking about exporting our primary materials, there is no future for the country"
So for once Colombia is exporting something other than a plant product (usually sold in small packets)...coffee and *ahem* the other one. The other one that is more expensive than gold, per gram.
