Paragraph text: These direct threats to the sustainability of fish production systems are magnified by the impacts of climate change. The rise in atmospheric carbon dioxide leads to increased sea temperatures and ocean acidification, threatening many calcifying organisms such as molluscs, plankton and coral reefs. This reduces dependent fish populations and is exacerbated by unsustainable fishing practices. Warmer sea temperatures may lead to more frequent and severe outbreaks of algal blooms, which can have a devastating impact on fish populations. Extreme climate-related events may destroy coastal habitats. Marine species respond to the warming of oceans by moving to colder waters, which includes shifting their latitudinal range or moving to greater depths. Some fish will gradually move away from rich tropical waters, resulting in localized extinctions and the invasion of some species into waters where they were previously not found.
