1)If the Black rhinos and its habits are protected then the other rhino species avoid extinction. 2) People living close to the Black rhinos, kill the black rhinos to make a living. By selling their horns and skin. If the there are no black rhinos then the people will start killing other species causing more and more species to become extinct.
Extinct is an incomparative word. Things are either extinct or not, you cannot have degrees or levels of extinction. At present the rhinoceros is greatly endangered and may become extinct.
no, some rhinos have become extinct, like the Vietnamese java rhino.........and also dinosaurs have become extinct, by the meteorites
if rhinos become extinct then the bobcat would become over populated, and then there would be a over populated area in which the rhino use to live.
The rhinoceroses run out and become extinct.
Rhinos are hunted for there horns they have three, so people would make a fortune selling them. White rhinos are more endangered than black ones, male white rhinos live by there self so do female ones so rhat makes it harder for them to breed.
