Books are generally considered more sustainable than e-books. While e-books do not require physical materials like paper and ink, they have a significant environmental impact due to the energy and resources required to produce and dispose of electronic devices. Additionally, the production and disposal of e-readers contribute to electronic waste, which can be harmful to the environment. On the other hand, books can be made from sustainably sourced materials and are often recyclable. Therefore, in terms of sustainability, books are generally the more environmentally friendly option. **
