Another great feat of humanity - The Black Rhino is officially declared extinct

The Western Black Rhinoceros (Diceros bicornis longipes), also known as the West African-Black Rhinoceros, was the rarest subspecies of the Black Rhinoceros (Diceros bicornis). In September 2011 it was considered as a subspecies extinct by the IUCN. It was once spread out in the savanna of west-central Africa, but the population declined due to predatory hunting.From 3 to 3.8 meters wide, it had a height of 1.4 to 1.7 meters and weighed from 800 to 1 350 kilograms. They had two horns, the first medium from 0.5 to 1.3 meters and the second from 2 to 55 centimeters. Like all black rhinos, it could be found on the savannah.It was a prominent target of hunters in the early 20th century, but the population grew in the 1930s after preservation measures were taken. Preservation efforts, however, declined over time, as did the number of Western-black rhinoceroses. In 1980, the population was hundreds. No captive animal was known, but it was believed in 1988 that around 20 or 30 were kept for breeding purposes. Poaching continued, and in 2000 it was estimated that only 10 animals survived. In 2001, the number decreased to 5.One of the strongest reasons for the extinction of the species lies in the scope of illegal hunting, and in the inefficiency of efforts to prevent the practice. The black-rhinoceros was last sighted in 2006, in Cameroon.
