Here's another one. The gem trade in Africa is the source of funding for many of Africa's bloody, seemingly permanent wars. The gems are bought by big companies and sold in jewelry in civilized countries where we don't have gem wars.

So, should people that buy emerald rings or diamond bracelets be jailed, because they are funding wars that kill hundreds of thousands of people every year? Or is that activity OK, because we all buy - or know someone who has bought - jewelry?
