Why do elephants have ivory tusks?
Iron ones would rust. :)
Poachers have decimated the elephant populations where elephants have large tusks. They kills elephants for their tusks, which is known as ivory. The ivory trade is illegal except in countries like China. As elephants with big tusks are killed off by poachers, only elephants with small tusks or no tusks at all at left to mate and have offspring.
Elephants have two tusks, which are made of ivory. The tusks grow to the right and the left sides of their trunks. Elephants can use their tusks to fight and to dig. People used to hunt elephants so that they could get their tusks. Ivory was used to make beautiful jewelry and statues. It is against the law to hunt elephants now, because hunting them made them endangered animals.
