The given line chart illustrates how the productions of three different products transformed (in million tonnes) regarding the forest sector recorded in a European country between 1980 and 2000.
Overall, all of the three products saw a substantial increase, in which paper was the highest production by the end of the timeframe, while pulp demonstrated the least progress almost entirely during the period.
Starting in 1980, timber remained the most widely produced with 6, which reached its peak at around 9 in 1985, almost 3 times bigger than the others. However, its figure decreased significantly approaching that of the start before regaining popularity by the end of the period. Similarly, pulp initially experienced a fluctuation between around 4 and 5 before witnessing a slight rise to its peak at 6, holding the lowest rank since 1985.
In contrast, despite being produced the least in the early stage at approximately 3, paper surged steeply in later years throughout the timeframe, overtaking the top spot of timber in about 1991 before ending the period at 10.
