>You can read a print book without wasting electricity

You don't 'waste' electricity, you waste your money. And in many places electricity is (much) cheaper than (good) paper.

>toxic materials used to produce a e-reader.

Surely you realise that different chemicals are used during paper production too? https://en.wikipedia.org/wiki/Sodium_sulfide and https://en.wikipedia.org/wiki/Sodium_hydroxide for example. And this depends on paper type too.

>Reading print is still a much more enjoyable experience

And this is entirely subjective.

>I can't defend ebooks compared to the reading, sharing, and the later selling

While I 100% agree with selling option, sharing is at least as easy with epub. Unless we are talking about a book from Amazon or something. In most cases you can just send a file over your preferred messenger.
