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

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. **
