The mountain gorilla is one of the world's most endangered species. During the Rwandan genocide in 1994, the gorillas' human security was gone so they were under threat of poachers. They also weren't having children.
The gorillas felt the stress the country was under. One theory holds they had become so habituated to people that when they stopped coming, they actually got depressed.
Rwanda, Uganda and the Democratic Republic of Congo have gotten together to help protect the gorillas. Today, there are 260 mountain gorillas inside Rwanda, and their numbers are increasing.
