Quaga
If you mean, depleted all of them, the Empire did. However there were a couple left, they were just hiding.
If you breed any horse with a zebra you'll get a Quaga.
They are not extinct yet, but there is a strong possibility that they will be, if we don't stop global warming. Their existence is threatened because their habitat, Arctic sea ice, is shrinking because of global warming.AnswerPolar bears are not extinct. Extinct means that a species no longer exists, such as the Dodo bird. Polar bears still inhabit Antarctica, however they are endangered. Some attribute their dwindling numbers to global warming causing loss of habitat and food. Their endangerment can also be contributed to man's hunting for their priceless hide, tendons, meat, fat and flesh. Their numbers dwindled from several hundred thousand to a few hundred in a few years time. In efforts to protect Polar Bears, an international agreement was set up in 1973 whereby only traditional weapons were allowed to be used in the hunting of the Polar Bears. Another AnswerPolar Bears are not extinct. If they get extinct it'll happen because of global warming. The heat will melt the glaciers on which polar bears live and they will have to swim long distances for food and will die as a result. So stop using your car and save Polar Bears!!! Other thoughtsThey are becoming extinged because the ice in the north is melting so they are having no more places to live.That's why we should stop global warning!!!!Atleats that's what i think.:^)
