Before the invention of paper, writing was done on rocks, leather, palm leaves etc.
The word “Paper” is derived from the name of a plant “Papyrus” that grows on the banks of the river Nile in Egypt.
Paper plays an important role in every field of literary human activity - from education and knowledge to entertainment and business. Train, bus, air or cinema tickets are all made of paper.
