Present Animal Extinction Rate and causes
Extinction of a species means that the animal is gone and might never be humanly restorable. Even those that might be restored might only be close approximations of the original ones. One example is the Wild Bull mentioned in the Bible, the Auroch. Despite all the efforts to restore it, we still have not been able to get the exact animal back.
There are also plans to restore the Passenger Pigeon, a bird whose vast numbers once darkened the skies over what is now the USA, but was hunted into extinction. The woolly mammoth is yet another target for such a restoration effort. True, these few might perhaps be partially restored someday, but the vast majority are gone forever. So why not prevent the extinction in the first place? Over 37,000 species are directly threatened with extinction. That is 28 % of all species assessed.
That's 97 percent of the causes traceable to our human activity, while only 3 percent is caused by other factors. I include invasive species in the 97 percent attributable to humans, because humans are the primary cause of invasive species.
Example? The Dodo, a bird which was once abundant in Madagascar, is said to have been adversely affected by the animals that were introduced by humans. Another is the Puerto Rican Coqui which was also introduced by humans to Hawaii and who are now threatening the native Hawaiian Island animals via competition for resources..
The Florida Everglade' wildlife is also threated by Asiatic boa constrictors and other species introduced by humans. Some purchase the snakes as small pets, and then decide to discard them into the wild when they become too large.
Within the next 15 to 40 years, it is likely that the following animals will become extinct: polar bear, chimpanzee, elephant, snow leopard, tiger, mountain gorilla, orangutan, giant panda, rhino, and the koala bear. Unfortunately, these are just a few of many…

The main threats causing extinction of species:
Exploitation: 37 % (hunting, fishing).
Habitat degradation and change: 31 %
Loss of habitat: 13 %
Climate change: 7 %
Invasive species: 5 %
Pollution: 4 %
Disease: 2 %
