Payment from tourists help buy roofs for houses, schools, and shoes for Rwandan citizens. It helps preserve the habitat of the animals being visitied. It employs citizens. Trackers keep track of primate groups and use radios to help the tourist's guides come quickly to the primates each day. This baby mountain gorilla was wandering near it's mother.
