You probably have stereotyped ideas about which countries are important, and which countries we could do without. Nobody would miss Bolivia, you think. We'd all get by okay if a bottomless pit opened up there tomorrow. Well think again. Those countries are important sources for important elements:
Bolivia -- tungsten
Turkey -- osmium
Mozambique -- tantalum
Kazakhstan -- bismuth
Burkina Faso -- manganese
Madagascar -- scandium
Afghanistan -- yttrium
Not sneering now, are you?
