What are some environmental issues with the Southern Ocean?

The Southern Ocean faces several environmental issues, including climate change, which is causing ocean warming and acidification, threatening marine ecosystems. Overfishing, particularly of krill and Antarctic toothfish, disrupts the food web and harms species dependent on these resources. Additionally, melting ice sheets due to rising temperatures contribute to sea level rise and alter habitat conditions for wildlife. The introduction of invasive species also poses a significant threat to the unique biodiversity of this region.
