Yes, human beings are also a threat to animals. Due to continuous poaching, many animals have either got extinct or have come to the stage of extinction. Elephants are killed for their tusks; rhinoceros for their hones, tigers; crocodiles and snakes for their skins and so on. Musk deer are killed to prepare scent from their musk. Further, growing human interference and destruction of forests have only aggravated dangers to these animals.
