Final answer:
The author's perspective is best represented by the idea that aquaculture will be increasingly crucial in the future, due to the need to sustainably meet the fish consumption demands against challenges like overfishing.
Step-by-step explanation:
The opinion that best expresses the author's point of view is that 'Aquaculture will be even more important in the future'. The material provided indicates concerns about overfishing and the need for alternative sources of fish to meet consumption demands. This inherently suggests that aquaculture is vital for future sustainability. The risks associated with aquaculture, such as introducing non-native species and the potential negative environmental impacts, indicate that it is a significant factor in future marine management. However, the overall tone and context suggest that the author views the role of aquaculture as increasingly crucial in the face of overexploitation of fisheries and the need to provide food sources for a growing human population.
