Check out the story on the CNN website: Central African Gorillas May Go Extinct.
It refers to a recent report by UNEP, the United Nations Environment Program, that states that gorillas may go extinct in much of Central Africa by the mid-2020s - victims of the meat trade, logging, mining and the Ebola virus.
The article and Unep report are slightly more optimistic about Virunga’s gorillas in particular (although very pessimistic about DR Congo in general), in that the mountain gorillas have survived despite long periods of instability in the region. The Rangers of Virunga who have died in the line of duty are also mentioned.
Have a read. Not very uplifting but that is the harsh reality.
