THE EFFECT OF GLOBAL WARMING ON WILDLIFE


Today, everyone is talking about Global Warming, what exactly is Global Warming?
Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent. Here is some of its effect on wildlife

Polar Bears
Polar bears, like their privileged springtime prey the ringed seal, depend heavily on sea ice for their survival. Polar bears move from ice flow to ice flow in search of the young seals. With rising temperatures, the thinning ice leaves
fewer places for both the polar bears to hunt and the seals to raise their young.
Arctic Foxes
The arctic fox is a phenomenon. Its paws are covered with thick fur to protect its feet in winter, and it is an excellent burrower which allows it to dig dens and warm itself against the arctic chill. In recent years, warmer temperatures have driven the arctic fox farther and farther north in search of more suitable, cooler habitat.

Adelie Penguins
When we think of Antarctica, it is with visions of waddling, tuxedoed penguins. Today, however, these iconic creatures may be in peril as a result of changes to their climate. Rising temperatures are causing the amount of sea ice to diminish, which in turn causes the amount of algae in the water to decrease. Many tiny organisms, including the krill shrimp which forms the foundation of the Adelie penguin’s diet, cannot survive without this important food source.
So what can we do to reverse this situation? Is this precious wildlife going on extinction too?
