According to the DC-based Stimson Center, ~60,000 African elephants and ~1,650 African rhinos [both species] were poached in 2012 and 2013. In just Kenya alone, the number of black rhinos fell from ~20,000 in the 1970s to ~650 today.
Poaching is a problemme of the poor in response to demand by the ignorant (or selfish) wealth. Yes, “subsistence poaching” remains a terrible problemme for the starving, but this social dilemma attacks poverty from a different angle. Regardless, the fundamental quandary that we are dealt with to solve is how to mitigate poverty. Yes, wildlife conservation is often more about people than about animals. If you can solve poverty in predominantly sub-Saharan Africa, giving everyone a job in which they are content with, providing individuals with an education, and establishing tremendous pride in their natural wealth, poaching will become a taboo. Until you establish poaching as a taboo, which cannot be articulated until the basic human needs are met, then poaching will go on.
