Yes - problem is some people (like me) prefer traditional writing on paper.
Some schools in my area including mine were given laptops to do our work alongside our schoolbooks, which did help in cutting paper as there were less handouts, we could answer past questions online and so on. But it was much more tricky to navigate a laptop than to use pen and paper.
Additionally when writing notes, you could argue that typing notes is better, but I and a lot of people find writing them is best as you actually process what you’re learning as making them instead of just mindlessly listening.
I do suggest using a whiteboard though, especially for recall if you have a small whiteboard when studying you can practice your recall again and again without using any paper.
Also maybe transferring from paper flashcards to apps like Anki and Quizlet which are fairly easy to navigate and I think you can download your sets to be offline too.
I think it’s going to be a while before schools can go paperless for studying, maybe even never, as it’s convenient and cheap and easy to access.
Maybe big notebook dispatchers (you know those standard blank coloured notebooks you’re given in every class), could try and use recycled paper for the pages or the covers, and that way every school will be reusing the books.
Also something my school did for English which was great is they had like 40 copies of Lord of the flies so each student in the class had one each, you’d annotate in pencil and them after the exam remove your notes and bring the book back to school so they could be reused the next year!
This is such an interesting thread 😊
