Endangered Species

What is an endangered species?
An endangered Species doesn't only refer to animals, but also fish and plants. An animal, fish, or plant becomes endangered when it becomes in danger of extinction. An animal becomes endangered when it's population of a whole across the world is limited not just in specific areas.

What animals are on the endangered species list?
Tigers, Giant Pandas, Rhinoceros's, Polar Bears, Whales and Dolphins, Elephants, Marine Turtles, Great Apes and many other species are considered endangered. Though Polar Bears are not yet officially on the list, researches believe it is not far off in the future. Less than 4,000 Tigers and Giant Pandas remain in the wild.

What causes endangerment?
one of the biggest factors leading to extinction is habitat destruction. Changes in our planet and from human effects play a big part. When changes occur at fast paces it doesn't give species the time the need to adjust. This is the main cause of extinction. Another factor is the introduction of exoctic species. Humans tend to place new exoctic species in habitats they do not belong it. This can lead to the native species of that area being prayed on by the foreign species.
