poaching for horns should be punishable by death, no ifs ands or buts about it. If its for food for starving kids fine, but not just to kill a rhino for its horn.
I know what you are saying, but really sport hunters hunt rhinos for the horn too, just legally.
Nobody is going to kill a rhino to feed starving kids. There is too much other protein around around that is simpler to obtain.
