Description:Nigeria’s commercial capital, Lagos, is a vast sprawling mega-city of 15 million people. Located on the country’s southern coast, Lagos is a hot, humid mass of humanity where life, for most, is tough. Lagos has a crumbling infrastructure that is a major problem for all the city’s residents, and Lagosians complain bitterly about the lack of a reliable supply of electricity. The majority go without, their homes and work places plunged into stifling darkness in the middle of the day.(4:52)
