I've heard that e-books can be more environmentally friendly. Is that true?

Yes, it is true. E-books are made from digital files and require less paper to produce than traditional books. This means that fewer trees will be cut down in order to make them. Additionally, the production of e-books produces fewer emissions than the printing and distribution of physical books. So e-books are generally considered to be more environmentally friendly than physical books.
