To conservationists, animals that came back from near extinction are like your favorite sports team scoring a much needed point at the last minute. They may not have Gatorade dumped on them, but the win means they're successful after many struggles and are safe for now. It's not just conservationists who should applaud these achievements since all creatures, even non-endangered animals, feel the ecological impacts of the extinction of an endangered species.
The International Union for Conservation of Nature (IUCN) is the worldwide organization that educates, researches, and advocates for animals threatened with endangerment. They have a "Red List" labeling system that puts threatened animals into categories from "Least Concern" to "Extinct." The world may have already lost the dodo bird, but there are many animals people think are endangered that actually aren't.
Whether people were mistaken about the facts or the animals were able to repopulate thanks to conservation, these creatures are all winners and will hopefully stay that way. Vote up the animals that you didn't realize are actually no longer endangered or were never even considered endangered.
