Additionally, the rise of fast fashion and disposable consumer goods in e-commerce contributes to environmental degradation and waste.

Finally, the convenience of e-commerce can lead to overconsumption and unnecessary purchases, further straining the environment. **

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. **
