Threats to Chimpanzees
As humans, we share about 98%of our genetic materials with chimpanzees. We also share some physical features and many forms of behavior. Although chimpanzees usually use both their arms and legs to move around, they can walk on two legs the way humans do for up to a mile. Both humans and chimpanzees can pick things up with their fingers. This ability helped humans to develop the use of tools. Chimpanzees are highly intelligent and, like us, use tools to accomplish tasks. Chimps use sticks and leaves, for example, to find and eat food and to drink. Also like humans, chimpanzees live in social groups. Living in social groups allows chimpanzees to help one another by sharing food and warning others in the group if there is danger nearby. Although chimpanzees do not use language in the way that humans do, they are able to communicate using hand motions, facial expressions, and different kinds of calls. They can be taught many complex tasks. According to some experts, chimpanzees even laugh like humans, especially when they get tickled!
        Sadly, human activity has started pushing chimpanzees toward extinction. Chimpanzee populations have already disappeared from several countries. One of the biggest threats to their survival is the loss of habitat. Humans are living closer and closer to chimpanzee habitats, sometimes cutting down forests to build villages and farms. Humans should not be allowed to live so close to their habitats because the animals can catch many human diseases.
        Illegal hunting is another major threat to this population. Poachers kill chimpanzees and sell their meat for food and catch live chimpanzees to sell to rich city residents for pets. Wildlife experts estimate that there may be as few as 300,000 chimpanzees left in the world. Several international conservation organizations are working with national governments across Africa to establish and maintain safe areas for chimpanzee populations and to fight against illegal hunting. The species can only be saved if we make serious efforts to protect the chimpanzees.
