I have read about a lady named Diane who went to to Africa a placed name Rwanda. Diane was raised and was from San Francisco . Diane located in Virunga mountain. During her 3rd year in Virunga mountain she studied about mountain gorillas in the wild. Diane stayed on the mountain for 18 years recording how they act and behave. Diane finally knew how to communicate with the gorillas, the gorillas began to trust Diane. Diane spent her life by protecting the gorillas from harm. In 1985 Diane was killed but her work is still now being carried on by others.
