Global warming is now threatening to endanger the Pacific walrus. Just this year, thousands were stranded on land for three months.

The effect of the steadily changing climate poses three problems to these animals: their habitats are changing, they might be forced to shore for long periods, and their weakest members are in danger when crowded on land.

Being stranded on the surface, the walruses are unable to forage for food on offshore foraging areas. This, in turn, puts more pressure on nearby areas to provide a consistent food source for the animals. Ideally, the walruses should be feeding in the rich waters of the ocean for their survival.

As an example to them being stranded on land, about 3,000 to 4,000 young walruses died this year in stampedes. In addition, a food chain for the walrus is also being affected by the changing climate.

If sea ice decreases and the temperature increases, it produces warmer water. This might decrease plankton which are food to clams, snails, shrimps, and worms, the main food source of the walrus population.
