Every year on September 22, World Rhino Day attempts to raise awareness of the dilemma facing the five threatened rhino species.
Events were overshadowed by the news that a record-breaking 635 rhinos were poached in South Africa since January. Last year, 688 rhinos were killed.
According to the WWF, illegal poaching has increased by 5,000 per cent in South Africa since 2007. This is because of a boom in demand from East Asia.
South Africa is home to about 75 percent of the world's rhinos, estimated at 25,000. But rhino poaching has skyrocketed in the past decade due to myths about the healing power of the rhino horns.
The horns are made of keratin, a fibrous protein that is the building block for skin and hair, and has no documented medicinal value. The horn has been reported to sell in Vietnam for up to $1,400 an ounce, near the price of gold.
Sumatran rhinos are by far the most vulnerable species. The WWF estimates that there are fewer than 100 in the wild today. Some are concerned that they will become extinct like the western black rhinoceros in 2011.
