Which is true about extinction?
True extinction, sometimes called species extinction or just “extinction”, involves either the loss of a species which existed in a single population instead of several, or the loss of all populations of a species to a larger causal event. Once an entire species is gone, there is no recovery.
How do we know if an animal is extinct?
Scientists can also leverage data analysis of past observations and fossil records to better predict when an animal might go extinct. If a species has been observed relatively consistently for a while and, suddenly, observations start to drop off, researchers may infer that all of its members have died out.

Why are so many animals on the verge of extinction?
Today, more and more animal and plant species are on the verge of extinction because of a variety of major factors that cause a species to become endangered, and as you might expect, humans play a role in quite a few of them. In fact, the biggest threat to endangered animals is human encroachment on their habitats. 1
How are humans causing other species to become extinct?
Humans also cause other species to become extinct by hunting, overharvesting, introducing invasive species to the wild, polluting, and changing wetlands and forests to croplands and urban areas. Even the rapid growth of the human population is causing extinction by ruining natural habitats.
