Extinct Animals In The World Information
About half of all the primate species on Earth are at the brink of extinction.
Extinct animals in the world information. The West Virginian woodland bison Arizonas Merriams Elk the Rocky Mountain grasshopper Passenger pigeon and Puerto Ricos Culebra parrot are all animals of the past now. Because a species potential range may be very large determining this moment is difficult and is usually done. 50 percent of all known mammals see rapidly decreasing populations and almost 20 percent are close to extinction.
Typically species have a lifespan of about 10 million years but there are some that stick around for hundreds of millions. Over a million species of animal and plant life are now threatened with dying out more than ever before in human history according to the International Science-Policy Platform on Biodiversity and Ecosystem Services IPBES.

In more modern times however human activity has been to blame. Animal extinctions may be caused by natural occurrences such as climatic heating or cooling or changes in sea levels. In just the past 40 years nearly 52 percent of the planets wildlife species have been eliminated.
The leading cause of these shocking declines is irresponsible and unethical human activities. Due to deforestation and uncontrolled hunting in the next twenty years this species may no longer exist. Scientist believe that about 99 percent of all species that have ever lived are extinct.
Marine mammals including dolphins whales and porpoises are particularly close to becoming extinct. Extinction is the termination of a kind of organism or of a group of kinds usually a speciesThe moment of extinction is generally considered to be the death of the last individual of the species although the capacity to breed and recover may have been lost before this point.
