Did you know there is an earth friendly type of paper called REPAP that is made of stone? No trees involved, just rock. Someone gave me a pad of it recently. I can honestly say it feels nicer to write on than plain old wood pulp-based paper.
Interestingly, it offers the benefit of being free of paper cuts, it’s waterproof and tear resistant. Since it’s stone it’s quite recyclable, and better for the planet.
An Italian company called Ogami uses it to make notebooks.
