Traditional paper is made from wood pulp, primarily sourced from trees such as pine, eucalyptus, and poplar. However, to ensure ecological sustainability, scientists and craftsmen have researched and developed eco-friendly paper using alternative materials such as leaves, bamboo, cotton, or recycled paper.<\/span><\/i><\/p>\n
