Marco is a chimpanzee. For the first part of his life, he lived with his father and six other chimpanzees in an old dilapidated truck in Valencia, Spain, and was used in a number of high profile television and print adverts. Within the truck, each chimpanzee was housed individually in very small 6×6 foot cages in total darkness. The chimpanzees had no choice but to sit in their own feces and leftover food. Marco spent the majority of his time inside the truck. In fact, the only time he was any light of day was when he had to “star” in the commercials. Sadly, this is the reality for most animals used in the entertainment industry; the bulk of their time is spent wasting away in a cage until they are pulled out to entertain."
