That's really a nifty idea. I find it weird that various species of rhino are going extinct. I just find it weird altogether that animals just end up wiped out and never to be seen again. I don't know why but that idea of an absolute end is strange. I read somewhere that two species were declared extinct or missing just recently in the news. They're poached for the horns because people pay big money believing they're a natural aphrodisiac. Kind of stupid.
