A reduction in sea ice due to climate change has negatively affected the food abundance of Penguins.
Explanation:
- Sea ice is ocean water frozen blocks. Unfortunately, rather than most other areas, climate change impacts Antarctica.

- The biggest threat to the penguins stems from changes in the Antarctic sea-ice cover, that will affect its feeding and breeding.
