Outside Egypt's capital, in the shadow of the Pyramids and tucked in the mountains of Mokattam, is an incredible city that literally survives on trash. Garbage City, as it's known, is home to 30,000 Zabaleens-- Coptic Christians from southern Egypt
--who, each day, enter Cairo and collect its waste. 60 percent of the trash produced in Cairo passes through Garbage City to be recycled. It is an amazing sight, awash in refuse.
