There are less than 1,000 mountain gorillas left on earth. Tourists can pay to visit families of these magnificent animals for one hour a day, up to eight tourists at a time. Over time, the gorillas have been habituated to being viewed by people and are tolerant of their visitors. Porters are hired from the local community to help the trekkers through the jungle. The porters are rotated on a regular basis so that more people in the community can work. In this way, the local community receives a benefit and poaching of the gorillas is less likely.
