The extinction of animals can be because of natural occasions together with warming or cooling of the weather or changes in sea stage. However, in more present day times, human sports have been accountable.
As agricultural land expands and forests are reduce down, habitat destruction, pollutants, the appearance of unique species, and fishing or searching are the primary reasons of modern-day extinctions. Increasingly, but, weather change is thought to be inflicting the extinction.
West African Black Rhinoceros
The West African black rhinoceros is discovered in many countries towards the south-japanese place of Africa.
This rhinoceros, three-3.Eight meters prolonged and 1.Four-1.7 meters high, ought to have weighed 800-1,3 hundred kg. It had horns, one measuring zero.Five–1.Three m and the alternative among 2–fifty five cm. Their food regimen consisted of leafy flowers and shoots.
Some believed that their horns had medicinal houses – no matter the truth that this changed into not grounded in scientific reality – essential to heavy poaching. In the 1930s conservation movement have become taken to defend the species, but numbers persisted to decline.

It is believed that the extinction of the saber-tooth cat may be connected to the decline and extinction of the large herbivores they hunted. Other reasons consist of climate alternate and competition with people.
