Poaching is by far the primary concern in the conservation of all species of rhinoceros. Secondarily, habitat loss definitely doesn't help.
When a species is said to be endangered, it means that the species may die out and become extinct. They are in danger of extinction.
Human activity and pollution will probably be the greatest cause of elephant extinction.

There is no evidence that any aliens exist so it is impossible to say how they may cause extinction.
The extinction of animals is caused by humans killing animals. Extinction of animals may also be caused by pollution or forest fires that are killing off the plants and trees.
