Bertholletia excelsa, commonly known as the Brazil nut tree, is a large tree native to the Amazon rainforest. It can grow up to 50 meters tall and produces large, round fruits that contain edible seeds, which are the Brazil nuts. These nuts are rich in healthy fats, protein, and essential minerals like selenium. The Brazil nut tree plays a crucial role in its ecosystem, providing habitat and food for various wildlife, including agoutis and macaws. It is also important for local economies, as the nuts are harvested and exported worldwide. Sustainable harvesting practices help protect the tree and its environment.
