Wearing brightly-colored dresses, children dance through the labyrinth of shacks and narrow alleys in Kibera, the largest urban slum and one of Africa’s most desperate areas. Nairobi's slums, with over 2.5 million people, represent more than half of its population, occupying only 5% of its area. And because of their constant population growth, there is an increase in unemployment, poverty, crime, scarcity of water and infections. Due to this heartbreaking scenario, children are the only ones who can afford to dream.
