Answer:
Pollution can significantly impact salmon in various ways. For instance, water pollution from industrial runoff or agricultural chemicals can degrade their habitat, making it harder for them to find clean water for spawning. Additionally, pollutants like heavy metals can accumulate in their tissues, harming their health and potentially affecting their reproductive success. Moreover, pollution can lead to the decline of prey species, disrupting the salmon's food supply and overall ecosystem balance. Overall, pollution poses a serious threat to the survival and well-being of salmon populations.
