The given line graph compares the figures for three different kinds of tree manufacture in the United Kingdom between 1980 and 2000.
Looking from an overall perspective, it is readily apparent that the amount of the production of paper and packaging experienced an upward trajectory and accounted for the highest figure throughout the period. Whereas there was a gradual decrease in the quantity of sawn-wood category with the data of wood pulp mildly fluctuated over the 20-year interval.
In 1980, the statistic for wood pulp manufactured was least significant at about 175 million tonnes, slightly lower than the amount of sawn-wood production by approximately 25 million tonnes. the following period of 10 years, both of these materials witnessed a steady downward pattern, converging at precisely 150 million tonnes with the data of the manufacture of wood pulp then overtook and rise steadily by about 10 million. Whilst, the sawn-wood figure continuously fell to reach the lowest point at just under 150 million tonnes in 2000
the output of paper and packaging’ made up nearly 250 million tonnes in 1980 and, thereafter, gradually grew to achieve exactly 250 million over 10 years. Afterward, there was a leap in its figure to peak at 350 million in 2000
