As this photo shows, Spanish authorities on Gran Canaria island, two days ago, transported sick African refugees in a garbage truck. I know that pigs, cattle and other animals are sometimes transported in horrible ways, with overcrowding, dirt, etc. However, so far I have not read about pigs or cattle being transported in a garbage truck.
These African refugees were ill. Transporting them in a garbage truck exposed them to pollution and worse illness.
