As the drone cleared a cluster of trees one of the first things spotted was what appeared to be a lake. This strange colored body of water, however, turned out not to be a lake but a huge lagoon filled with pig sewage.
This toxic stew of pig feces and urine falls through openings in the floor of the factories where the pigs are housed. It’s then flushed into this open pit. While the drones can’t transmit smells while recording footage, Devries has stated that the stench from the pits can be overwhelming.
