Rhino's situation in the IUCN list

Rhinos are at grave risk of disappearing from our world because of human greed: a truly heartbreaking prospect. Their horns are believed to have medicinal benefits (despite being composed entirely of keratin – the same substance that forms human hair and nails). Three rhinos are killed for their horns every day. The Javan rhinoceros was declared extinct in 2011, while the Western Black rhinoceros suffered the same fate in 2013. The Sumatran and Black Rhino subspecies are currently classified as “critically endangered” by the International Union for the Conservation of Nature (IUCN). Following the death of Nola – one of only four remaining Northern White Rhinos – last November, the outlook for this subspecies is also looking extremely bleak.
