Out of Africa?

Disturbing news about the intensity of poaching on Africa's unique mammals (http://www.awf.org/campaigns/poaching-infographic/). it seems that numbers of elephant, rhinoceros, gorilla etc are in marked decline. Drivers seem to include a new affluence in China (increasing the demand for items used in 'medicine') and the technologies now available to poachers. The incidence of capture and successful prosecution of 'Mr Bigs' in the poaching world is also disappointing. It could be the case, that many of these important animals will disappear from our world.
