How many endangered species are in Africa?

• I'm doing a project on endangered animal species in Africa, but I've looked all over and I can't find an estimate about how many endangered species are in Africa

• Answer:

  Everyone knows what the words “extinct” and “extinction” mean. They tell us that a species has vanished from the earth, just like the dinosaurs. Since life began on our planet, about 99 percent of all species that ever lived have gone extinct—most of them due to natural causes. Extinct are the tyrannosaurus rex, the woolly rhinoceros, the mastodon, the trilobite, and the saber-toothed tiger. Humankind played no role in most of these extinctions. However, we are responsible for many hundreds of the most recent ones. The passenger pigeon is gone because of us; so is the wild dromedary camel, the dodo bird, the Javan tiger, the dusky seaside sparrow . . . the list could go on and on. But many other species, although not yet extinct, have disappeared from large areas of their original, natural habitat. Wildlife experts say that these creatures have been extirpated from parts of their former range
