Dian fossey went to central africa because she was interested in mountain gorillas. mountain gorillas are big animals with long arms and long black hair. scientists did not know about them before 1902. they only live in two places, and there are only about 600 them in the world. dian worked with gorillas in rwanda and after some time she understood them very well. but hunters killed gorillas because they got a lot of money for their heads and hands. when hunters killed one young gorilla called digit, dian was very angry. she talked to a lot of people about the animals and money came to her from many countries for their protection. she started the dian fossey gorilla fund. when you send money to the fund, you get a photo of ' your' gorilla, and the fund uses the money to help the mountain gorillas. dian was very famous after she wrote her book gorillas in the mist.
