Mountain gorillas live in forests where some people hunt them illegally.
Ecotourism has been set up so that visitors pay to see the gorillas.
Which statement explains how ecotourism can help to reduce the hunting of gorillas?
Gorillas get used to people, so they hide less and are easier for rangers to count.
Visitors pay to hunt a few gorillas each year, so fewer gorillas are hunted illegally.
Tourists scare away the hunters, so gorillas can live anywhere in the forest safely.
Local people earn money from visitors, so a living gorilla is worth more than a dead one.
