Global Voices Online wishes you a Happy Africa Day with a poem from Mighty African :
It takes a village to raise a child
It takes a male child to start a village
It takes a female child to educate them all
One man’s inactive car
Is many other men’s community service
Because you will need others
When your own car breaks down in Africa
It doesn’t fall into winter
And then spring into summer
People may be raining away
But life and warmth never run dry in Africa
Tangerine tree, football field, sugarcane seller
Very different but similar
Who needs Mapquest? In directing and navigating
All landmarks are on deck, in Africa
