Rhino are under serious threat from poaching which is a major concern for everyone and has created some very successful (if expensive) anti poaching initiatives.
This year however, there is yet another threat to these animals due to the drought in Africa. This has caused some game reserves to take the unusual step of laying food out for Rhino (and of-course other species that come along). Feeding animals is not the norm and is frowned on in many circles. The theory being that drought is part of the normal cycle in nature. The debate will no doubt continue as to whether we should interfere or not, but at the end of the day, whether it be feeding or anti poaching patrolling, we need to protect this species.
