Hello everyone. 1) Can I ask you all to close your eyes
climbing, rolling in the mud and having fun, while the
mothers relax close by, keeping an eye on them. Where
are you? At a playground? No! You're on a mountain in
Africa watching a group of amazing mountain gorillası
Mountain gorillas are wonderful animals, but they could
become extinct if we are not careful. There are only about
700 of them left! 2)
I'd like to tell you a few
things about these gentle giants. 3)

mountain rainforests of Africa, so they are quite well-hidden
cary, but really they are very gentle creatures who live together
The family has got a big, male leader, called a silverback. The
only become aggressive when he thinks his family is in danger.
