With rampant poaching threatening the survival of Africa’s rhinos, an all-star team of Chinese celebrities is speaking out against the sale of rhino horn — by chewing on their own fingernails.
Why? Rhino horn is primarily made of keratin, a protein also found in human nails and hair. In recent years, international criminal syndicates who peddle the use of rhino horn in countries as such as China and Vietnam have marketed the product as a medicinal panacea when ground into powder form and ingested. Such uses include a recreational drug, an aphrodisiac and even a cancer cure.
