Paper is produced from Wood. The fibres of Wood from trees are mixed with water until they becomes a soft wet pulp, which is dried. This method of paper making was invented in the 2nd Century BC in China. However, early writing material weren't always made from Wood. In fact, the word paper comes from papyrus plants which were used by Egyptians to make a form of paper in 3000 B.C. When machines for paper making were introduced in the 19th Century, paper became easy to afford. Today, one of the problems with the huge production of paper is that a chemical called chlorine is added to make the paper white. Recycling is important, because chlorine is not needed and less energy is used for recycled paper.
