The line graph given in the prompt illustrates how much paper, wood pulp and sawn-wood was produced in the UK over the course of twenty years, commencing from 1980.
Overall, there was an upward progression in the volume of paper and packaging, while the other two productions showed an downward tendency. Another key feature is that the quantity of paper and packaging was always made the most out of forest industry throughout most of the period. Wood pulp ranked lowest at the begining of the examined period, however, sawn-wood registed the lowest figures at the ending-year in 2000.
In 1980, the number of paper and packaging accounted for around 230 million tonnes, ranking at first out of three production examined. This figure then rose steadily to 250 million tonnes in next ten years. The rest of the period witness an upsurge in manufacturing this product, finishing at 350 million tonnes , remaining the first industry place.
In comparison, wood pulp and sawn-wood present a decrease trend in manufacture. In terms of the former, exactly 200 million tonnes of sawn-wood were created initially, after which it underwent a progressively decline in its production, ending at approximate 130 million tonnes at the end, ranking the lowest place in forest trade since 1990. Regarding the latter, the volume of wood pulp started at the lowest figures in production , with nearby 160 million tonnes. After experiencing a slightly fractuation in wood pulp products, hitting the bottom at around 150 million tonnes in 1990, prior to a steadily increase to the neiborhood of 140 million tonnes at the ends.
