AI overview

Ivory is a hard, smooth material from the tusks of elephants and other animals that craftspeople throughout history have carved into decorative objects and artwork. It matters today primarily because the ivory trade has driven elephants toward extinction, making ivory a symbol of wildlife conservation efforts and international trade restrictions.

象牙是一种白色硬质物体。主要成分为牙本质,和骨头的成分相似。狭义地说是雄性的亚洲象、非洲象、猛犸象的獠牙,广义地也可以指河马、野猪、海象、鲸等动物的獠牙或牙齿。 象牙是一种贵重的材料,用来制作牙雕、假牙、扇子、骰子等。近代用来做或用具,如、台球、骰子、钢琴键、麻将、扣子等。塑料出现之后,在众多领域替代了象牙,但因为象牙的稀有,一些奢侈品仍然使用象牙。 在国际范围禁止象牙贸易。
