Walruses spend a lot of time hunting in arctic waters. when they need to rest, they move onto floating pieces of sea ice. scientists have recently observed walruses frequently leaving the water to rest on land for longer periods of time. what is the most likely reason the walruses are resting on land instead of on sea ice?

Decline of sea ice as a result climate change. Global warming has made sea ice less available.

Explanation:

Walruses are naturally known to spend most of their lives on floating ice for resting and breeding purposes, while they only dive into the icy sea waters to hunt for food. However, recently, there has been a deviation from this normal trend of the walruses. It has been observed that walruses now move to nearby shores and beaches during their resting periods when they are not hunting.

This deviation has been linked to climate change in form of global warming. The decline in sea ice at the arctic region for walruses has been attributed to Global warming as a result of increased global temperature. A rising global temperature has led to the melting of more ice and deepening of sea water levels, leaving little or no choice for walruses to swim farther to shores around especially during resting periods for longer time.
