Walrus Conservation and Climate Impact

The video discusses the impact of extreme ice melting, leading to a large gathering of walruses on a Barrier Island in Alaska. This situation poses dangers due to the risk of stampedes, especially affecting calves and juveniles. Aerial footage was captured by the USGS, with strict no-fly zones to prevent disturbances. Walruses typically forage on the sea floor and use sea ice for resting. This is the first time such a large gathering has been observed in Alaska, though similar events have occurred in Russia. The WWF notes that Arctic sea ice is at its third lowest level, prompting further research by the USGS on climate change effects.

What is a significant risk associated with large gatherings of walruses on land?

• They might get lost.

• They could start a stampede.

• They may become dehydrated.

• They could overheat.

Why is there a no-fly zone near the walrus gathering area?

• To prevent noise pollution.

• To avoid disturbing the local wildlife.

• To protect the aircraft from damage.

• To prevent a potential stampede.

What do walruses typically use as a resting platform between feedings?

• Sandy beaches

• Floating logs

• Sea ice

• Rocky cliffs

Where have similar large gatherings of walruses been recorded in the past?
