If fishing demands continue at the current rate, by which year will the world's major fisheries collapse?Multiple Choice2125207520502100

A fishing community is experiencing a decline in fish stocks due to over-harvesting. The community must decide whether to implement fishing quotas to sustainably manage the fishery, which could lead to short-term economic losses but long-term environmental benefits.   Year Fish Harvest (tons) Economic Impact (USD) Fish Population Decline (%)2019 1000 1,000,000 302020 950 950,000 252021 900 900,000 202022 850 850,000 152023 800 800,000 10Based on the data table, what trend can be observed regarding fish harvest and fish population decline?    A.As fish harvest decreased, fish population decline decreased.B.As fish harvest decreased, fish population decline increased. C.There is no clear relationship between fish harvest and fish population decline. D.Fish population decline remained constant regardless of fish harvest.
