For most of us (myself included) I suppose initial interest stem from events that impact us directly…(other than catyclismic events such as recent Tsunami)…
but once an interest is sparked can stimulate broader concerns…
BTW,
Your post stimulated myself to look up burkina faso.
I didn’t know what/where/who it was…
I discovered that Burkina Faso is one of the poorest countries in the world, Aids is epidemic, and that troubles in bordering Ivory Coast have crept into the region.
