How much paper do you use every year? Maybe you can't answer this question quickly. In 1990, the world's use of paper was about one kilogram for each person in a year. Now some countries use as 50 kilograms of paper for each person in a year. But countries like America, England and Sweden, certainly use more paper than other countries.

　　Paper was first made in China about 2000 years ago. It was made from the hairlike parts of certain plants. Paper was not made in southern Europe until about the year 1100. In 1500, a German named Schaeffer found out that one could make the best paper from trees. After that, the forest countries of Canada, Sweden, America and Finland became the most important ones in paper making.

　　Each year more and more things are made of paper. We have had paper cups and plates for a long time. Now we hear that chairs, tables and even beds can be made of paper. With paper boots and shoes, you can wear paper hats, paper dresses and paper raincoats. When you have used them once, you throw them away and buy new ones.

　　People have made paper boats, but they haven't made planes or cars. Just wait--they perhaps will some day.
