Final answer:
None of the punishments by chief heavenly spirits would actually occur, as they are not based on biological interactions. Polar bears are the animals most affected by the melting of sea ice in Alaska, as it significantly impacts their habitat and access to food, leading to potential ecological imbalance.
Step-by-step explanation:
The chief heavenly spirits mentioned in the question are not relevant when discussing factual occurrences in the natural world such as the consequences of habitat changes on wildlife. Hence, none of the punishments listed (A, B, C, or D) would occur as they are based on mythology or spiritual beliefs, not on biological interactions. However, discussing the impacts of environmental changes, particularly melting sea ice, it is clear that polar bears would be most adversely affected amongst the animals listed.
Polar bears rely heavily on sea ice for access to their primary prey, seals. As the sea ice melts, seals become harder to access, and the polar bears may be forced to move inland in search of food. This change could lead to a disrupted food web, where polar bears coming into competition with other predators, such as grizzly bears, could lead to further ecological imbalance. Migrating polar bears may find it difficult to obtain the same caloric intake from alternative food sources on land.
