The document discusses tagua, a natural material from Colombia that is used as a sustainable alternative to ivory. Tagua comes from the nuts of the tagua palm tree, which grows in Colombia's Pacific coastal rainforests. The tagua nut resembles an ivory color when carved and polished. For centuries, tagua has been used to make buttons, handles, and other accessories as a vegetable substitute for elephant ivory. Its use helps conserve elephant populations by providing an alternative material for jewelry and crafts. The tagua industry has become commercially successful and an interesting gift option made from Colombia's biodiverse coastal rainforests.
