Other than at the zoo, there aren’t many options for Americans to come into contact with a rhino.  It’s also becoming increasingly rarer to come into contact with them in their native countries.  Black rhino populations, like other rhino species, have fallen drastically since 1970.  Savetherhino.org estimates that in 1970, there were around 70,000 black rhinos in Africa, but now there are only around 5,000.
