Overfishing along the Pacific Coast leads to loss of biodiversity, increase in invasive species, and depletion of fish stocks, all of which have serious ecological and economic impacts.

Overfishing along the Pacific Coast has multiple negative consequences for the ecosystem. First, loss of biodiversity occurs when key species, such as certain fish and marine mammals, are over-harvested, disrupting the balance of the marine food web. Second, the absence of native species can lead to an increase in invasive species, as non-native organisms can thrive in the absence of natural predators. Third, depletion of fish stocks reduces the availability of important fish species for both the ecosystem and the fishing industry, leading to economic losses. The combined effects of these factors threaten marine ecosystems and local economies.
