The provided line graph presents data on the manufactured quantities of three forest derivatives – paper and packaging, wood pulp, and sawn wood – in the UK across a two-decade span, commencing in 1980.
Overall, it is readily noticeable that while the figures for paper and packaging demonstrated a marked increase, the opposite trajectory was evident for sawn wood. Additionally, paper and packaging consistently held the pre-eminent position in production volume among the three listed outputs during the entire measurement period.
Looking primarily at the dominant material, the production figure for paper and packaging secured the leading rank, starting at approximately 225 million tonnes in 1980. During the initial decade, a gentle upward movement was recorded for this product, with its value rising from its starting point to an exact 250 million tonnes by 1990. Furthermore, the output of paper and packaging underwent a considerable boom thereafter, escalating sharply from 250 million to 350 million tonnes one decade later. Consequently, it maintained its position as the highest-produced item throughout the investigated timeframe.
Shifting focus to the remaining materials, sawn wood, despite reporting the second largest initial volume at about 200 million tonnes, then experienced a sustained drop to 145 million tonnes in 1990. Subsequently, this contraction continued, with the figure falling to roughly 125 million tonnes in the final examined year. Regarding wood pulp, its output underwent a minor reduction from 165 million tonnes at the outset to 145 million tonnes in 1990. Nevertheless, the data for wood pulp saw a modest recovery in the subsequent period to reach approximately 160 million tonnes by 2000, thereby overtaking that of its sawn wood counterpart to achieve the second rank.
