A donkey carrying sacks of coal walks through the narrow tunnels of a coal mine, in Choa Saidan Shah in Punjab province April 29, 2014. Coal miners in Chao Saidan Shah use donkeys to transport coal from the depths of the mines to the surface. The donkeys make around 20 trips per day carrying sacks weighing about 20 kg (44 lbs) each. The work is dangerous with the constant risk of cave-ins. The miners say they do what they can to care for the animals, with their limited resources, but the difficult conditions mean the donkeys' life expectancy is 12-13 years. May 8 is International Donkey Day, which The Donkey Sanctuary NGO says "aims to highlight the worthy contribution donkeys make throughout the world." Picture taken April 29, 2014. REUTERS/Sara Farid
