Worked Solution & Example Answer:Analyse the data shown in Figure 11 and Figure 12 - AQA - A-Level Geography - Question 6 - 2018 - Paper 1
Step 1
Analysis of Figure 11
Answer
Figure 11 indicates that various regions are experiencing a decline in top marine predators. Most notably, the Baltic Sea has a concerning decline of almost 11%. Moreover, the median value of decline for these regions is about 4.5% - 5%. This suggests that top-level marine predators are increasingly endangered and may face significant challenges in terms of habitat and fishing pressures.
Step 2
Analysis of Figure 12
Answer
Figure 12 shows a worrying trend in the proportion of fish stocks, with a significant number of regions highlighted as overfished. For instance, the Gulf of Lions is noted as having 17 out of 25 stocks overfished, which raises alarms regarding marine resource sustainability. Similar patterns can be observed across several regions, particularly in the North Sea, where the fishing industry may be surpassing safe limits, contributing to the overall decline seen in Figure 11.
