In the absence of Cold Labrador Current, which one among the following would happen ?

The Labrador Current is a cold current that flows southwards from the Arctic Ocean along the eastern coast of Canada [3]. It meets the warm Gulf Stream off the coast of Newfoundland, specifically near the Grand Banks [1]. This confluence of cold and warm waters is critical for the creation of one of the world's most productive fishing grounds in the North-West Atlantic [1]. The mixing of these waters facilitates the growth of plankton, which supports vast fish populations like Atlantic cod. In the absence of the cold Labrador Current, this specific convergence would not occur, leading to the disappearance of the North-West Atlantic fishing grounds [1]. While the North-East Atlantic also has fishing grounds (e.g., near the North Sea), they are primarily influenced by the North Atlantic Drift rather than the Labrador Current [2].
