The graph illustrates the utilization of three forest resources, namely pulp, timber and paper in European country from 1980 to 2000.
At first glance, it is apparent that paper production experienced a remarkable surge, while timber and pulp production demonstrated erratic changes with some peaks and declines through each year.
Looking at the graph in more detail, we can see that the data for paper proliferated from 4 million tonnes to around 9 million tonnes dramatically from 1980 to 1995, then it remained that change and finally it stopped at 12 million tonnes in 2000. The opposite trend was true for the figure for pulp, when it started at 6 million tonnes in 1980 but then decreased to only 3 million tonnes in the first half of 80s. However, when it came to the second half of 80s, it burgeoned drastically at around 7 million tonnes in 1985 then maintained the noticeable change until the early 20th century and it ended at about 10 million tonnes in 2000. The difference can be seen at the data for timber, when it began at 5 million tonnes but then increased rapidly to 10 million tonnes in the first half of 80s. Nevertheless, it declined suddenly from 10 million tonnes to around 7 million tonnes between 1985 and 1995. Furthermore, in the second half of 90s, it increased slowly to 8 million tonnes finally it stopped at around 7,8 million tonnes significantly.
