Throughout the Nairobi’s Jomo Kenyatta International Airport and other airports in Africa, dogs are being trained to sniff Ivory. The ivory from elephants is used in the making of X-Ray machines and screeners and is becoming increasingly rare. The elephant population in Africa is decreasing rapidly because they are being killed for their ivory. Rocco is an ivory sniffing dog who is let go in airports and sniffs people’s luggage. If someone is caught with ivory hidden in their suitcase, they are arrested by the authorities.
