Paper was invented by a Chinese man called Cai Lun almost 2,000 years ago. But it was not made in Europe until the year I 100. Four hundred years later, a German discovered that he could make the best paper from trees. After that countries rich in forests, such as Canada Sweden. America. Finland became the most important ones in paper making

In short, we should keep a balance (平衡)between using paper and protecting trees, and do it now before it is too late.
