The charts illustrate the transformation in the steel economic field throughout the 30-year period since 1970.
Overall, the line graph contains two main factors which suffer from general downward-trend that present for the abatement in solid material requirement in construction needs in the UK. Conversely, the proportion for importation noticeably rises, which might be a practical activity to protect the environment. Meanwhile, the area chart shows the decrease in jobs requested in the steel industry.
Beginning with line graph, UK steel requirement and production started at around 150000 and 20000, respectively. After two decades, those suffered from a markable diminishing, stopping at nearly 10000 for exploration besides over 10000 for UK consumption. From 1990 to 2000 the steel proportion required for UK construction almost remained unchanged, whilst the production factor witnessed a slight increase to nearly 80000. In contrast, importation noticed an upward-trend through three decades recorded, raising approximately 65000.
Moving to the area chart. The employment requirements in the steel industry started at 50000. In one 10-year period later, it suffered a significant fall of around 30000. While at the time from 1990 to 2000, it witnessed an unnoticeable abatement to approximately 20000. Those were caused of the abatement of steel demands and exploration of the UK.
