Ivory is a dense, white material made from the tusks and teeth of animals, primarily elephants, walruses, and hippos. It has been valued for its beauty and durability, making it a popular choice for crafting items like jewelry, piano keys, and decorative objects throughout history. Due to the decline in elephant populations caused by poaching for ivory, many countries have implemented strict regulations and bans on ivory trade. Conservation efforts aim to protect these animals and their habitats, ensuring that future generations can appreciate their existence and the ecosystems they support.
