16 year-old David Were lives in Kibera, Africa’s largest slum on the outskirts of Kenya’s capital city, Nairobi.  Basic facilities like the bathroom become an enormous chore as the family uses buckets and plastic bags to dispose of human waste.  The bags, or “flying toilets,” are not just a problems for David’s family, but have become an ecological obstacle for the entire community who toss bags from the window, afraid to leave their homes at night.  For David and his friends, their work to provide security, latrines and clean up projects for the flying toilets, is more than a struggle for a healthier environment.
