Lagos, Nigeria (CNN)Sharon Okpoe has lived her entire 17 years in Makoko—known as the world’s largest “floating slum”—built on a lagoon in Lagos, Nigeria.
Rickety shacks stand on stilts in the polluted water. Canoes are required transportation through the maze of narrow canals. Okpoe’s father is a fisherman, and her mother sells smoked fish, eking out a living on the fringes of Africa’s largest city.
Lagos has a thriving economy built on oil, finance and manufacturing. And the city is now considered Nigeria’s Silicon Valley, with Facebook and Google opening offices there earlier this year.
