Overharvesting remains the second-largest cause of global species decline and extinction. The illegal wildlife trade, worth $19 billion to $26.5 billion per year to transnational organized crime, is the world's fourth most profitable illegal trade, after drugs, human trafficking and counterfeiting.
The conspicuous absence of wildlife trade on the dark web suggests that traders are content to hide in plain sight on the surface by using popular auction sites such as eBay. Since online trading is poorly monitored, the traders simply rely on the sheer volume of transactions to mask their activity.
Ebay needs to ban the selling of rhino horns, elephant tusks, and wildlife trophies to help stymie poaching and the criminal trade in animal parts.
