Dozens of Colombian waste pickers inundated Bogota's iconic Bolivar Square with about 15 tons of recyclable goods Tuesday to protest decreasing income and tougher conditions for scavengers. The demonstration was organized by 14 waste picker associations in Bogota, a city where approximately 20,000 scavengers work long hours gathering and then selling items like plastic bottles, scrap metal, and cardboard boxes from homes, factories, and office buildings. About 100 waste pickers gathered and some pretended to swim between the mounds of trash, reports the AP. More:
