Madagascar is home to many species that were not known about until around 1679 when Dutch explorers went there. They do not even exist elsewhere in Africa. They only exist in Madagascar. In fact, most of the mammals living in Madagascar do not live anywhere else in the world. However, many of the species in Madagascar are in danger because many of the forests have been cut down. A big reason that forests have been cut down is so that land can be used to grow crops such as coffee, which is one of the most important crops that is grown in Madagascar.
