On Wednesday, police in Nigeria’s largest city fired tear gas on people protesting the ongoing demolition of Makoko, an enormous informal settlement that stretches out into the Lagos Lagoon. With over 300,000 estimated inhabitants, the settlement of DIY housing on stilts connected by canals is considered the largest of its kind in the country and was long home to some of Lagos’ poorest. The World’s Host Marco Werman learned more about the impact of the demolition from Nnimmo Bassey, a Nigerian environmental activist and architect.
