Chinstrap penguins are threatened by changes in their environment, specifically global warming and ocean acidification. As the Earth’s temperature continues to rise, chinstrap penguins will have to migrate further south in order to find suitable nesting grounds. If they are unable to relocate, their populations will decline. In addition, ocean acidification caused by climate change will make it difficult for chinstrap penguins to find food, as their prey will be less abundant in acidic waters. This could lead to starvation and population decline.
