Garbage recycler Maria Aparecida (lower L), 48, watches as Jose Carlos throws a sack of garbage to be recycled, under the Glicerio viaduct in downtown Sao Paulo March 14, 2014. Brazil generates 250,000 tons of waste every day, according to official estimates, and the city of Sao Paulo is the biggest contributor to that with 19,000 tons. Under the Glicerio viaduct, workers known as "catadores" select material to send to recycling centers, amounting up to some 100 tons each month. Picture taken March 14, 2014.
