What is a major impact of climate change for fish species

Question

Shifting ocean currents
Food toxicity
Too much carbon dioxide in water
Changes in ocean habitat

Answer 1

A major impact of climate change on fish species is changes in ocean habitat. As ocean temperatures rise and acidification occurs due to increased carbon dioxide levels, the habitats that many fish species rely on—such as coral reefs, kelp forests, and other marine ecosystems—are negatively affected. These changes can lead to shifts in species distribution, disruption of spawning and feeding grounds, and overall impacts on fish populations and marine biodiversity. While shifting ocean currents and increased carbon dioxide in the water also have significant effects, the alteration of habitats is a fundamental concern that directly impacts fish survival and diversity.
