What conclusion can be drawn about the status of salmon populations?

The conclusion that salmon populations require ongoing protection is supported by the understanding that many fish species, including salmon, face various environmental challenges that threaten their existence. Factors such as habitat destruction, pollution, overfishing, and climate change can significantly impact their populations. Recognizing the need for ongoing protection implies that while some efforts may have been made to conserve these populations, they still face risks that could lead to declines if not adequately addressed. Therefore, advocating for continuous protection highlights the importance of conservation measures to ensure the sustainability of salmon populations in the face of these ongoing threats.
