A package of new educational course has just come out. It was written by John three years ago. Itcovers/includes a book and three CD-ROMs. It covers many topics. The book tells us that the weather has changed a lot during the last/recent thirty years. The temperature is getting higherand higher. The book teaches us how to reduce pollution and protect environment. It also asks us to do voluntary work as much as possible. John hopes more and more people will take part in the event like this.
