Human activities have significantly impacted the Antarctic food web, including through whaling, which has been a major factor in the decline of krill populations. The reduction in pack ice due to climate change affects marine algae production, which is crucial for krill, and a lower krill population negatively impacts species that depend on them, such as penguins and fur seals, reducing their breeding success.
