Hi, there. How are you going with your tutorial next week? Oh, good. I've decided to talk about paper and its use. Fascinating, I'm sure. Yes, I think it's an interesting topic. Do you know how much paper you use every year? Well, I've never thought about that. I can't answer your question. I suppose you can tell me something about it. OK. It'd be a good practice for my tutorial next week. How much paper does one person use every year? In 1900, the world's use of paper was about one kilogram for each person in a year. Now some countries use as much as 50 kilograms of paper for each person in a year. This shows how far advanced the country is. You're right. Countries like the United States, Britain, Japan, Germany and Sweden certainly use more paper than other countries. I'm very interested in the history of paper. Are you going to talk about it next week? Yes, of course.
