The graph, showing a drastic increase in fish caught from 1950 to 2000, suggests poor environmental quality in the world's oceans. The high demand for fish, leading to overfishing, indicates the depletion of natural resources, posing a threat to marine ecosystems. Hence, option C is correct.
The graph suggests poor environmental quality in the world's oceans because of the drastic increase in the number of fish caught over time, from 1950 to 2000. The correct option is:
c. The high demand for fish means that natural resources are being depleted.
The significant increase in fish catch indicates a high demand for fish, likely driven by overfishing. This can lead to the depletion of natural resources, disrupt ecosystems, and harm marine biodiversity. Overfishing is a major environmental concern as it can lead to the collapse of fish populations, impacting the health of marine ecosystems and threatening the livelihoods of communities dependent on fisheries. Therefore, the observed trend in the graph is indicative of poor environmental quality in the world's oceans.
