Step 1
Figure 11: Analyse the percentage change in top marine predators
Answer
The data from Figure 11 shows that numerous areas are facing a decline in top marine predators, with the Baltic Sea experiencing the most significant loss, around 11%. The Arctic North West and North Sea also exhibit notable declines, while the Mediterranean Sea appears to maintain relatively stable predator numbers. It’s critical to highlight the median loss of 4.5% - 5%, indicating a common trend across most regions. The consistent pattern of decline can be attributed to overfishing and environmental changes.
Step 2
Figure 12: Examine the status of fish stocks within safe biological limits
Answer
Figure 12 illustrates the health of fish stocks across different regions. The North Sea displays severe overfishing, with over 75% of fish stocks reported as overfished. In contrast, areas such as the Gulf of Lions show a more positive assessment, yet overall still reflect a concerning trend. The varying conditions across regions suggest that while some areas are managing to maintain stocks within safe biological limits, the overarching regional trend still points towards decline and stresses the necessity for enhanced conservation efforts.
