What a tragedy it has come to this. The last known northern white male rhino in existence and the species last hope of survival. In 2011 the western black rhino was declared extinct, wiped out by human greed after roaming the earth for an incredible 5 million years. We ought to be outraged and ashamed that this could happen, yet here we are with the last known male white rhino in 2015 just four years later. Am I just unrealistic to wonder if there are so few left why their horns have not been removed to ensure their survival. I mean why kill them if there is nothing to take ? Is this what is going to happen to elephants too ? As another species man has a lot to answer for, mostly the unrelenting greed that has driven this tragic situation to such a sad end.
