Isnt it the same people saying elephants and rhinos are threatened that are saying bobcats and coyotes are endangered?
Javan rhino 69
Sumatran rhino <80
Black rhino Between 5,366 and 5,627
Greater one-horned rhino 3,500+
White rhino Between 17,212 and 18,915
There aren't many rhinos left especially of some species, there's a real risk of killing them all. Those poachers would kill the last one on earth just to saw it's horn off and sell it to some rich Chinese business man that can't get an erection or has a hangover if they got the chance. Whether or not it matters if we have rhinos is debatable, I guess.
