Essay On Polar Bear Extinction

This is a key question to the whole project.  Besides the fact that they
are cute and cuddly - polar bears are important for many reasons.  Polar
bears are what are known as an umbrella species; many organisms are
connected to polar bears via a food web.  For example, the Arctic Fox
depends on the polar bear for food - they eat the left over seal carcass
after the polar bear is done.  Polar bears feed on seals, without the
predator then the seal population might increase also affecting the fish
that seals feed on - and so on.

Another reason to care about the polar bears is the overall notion of
biodiversity.  Biodiversity refers to the number of different species.
For example there are millions of different species of beetles.  While it
may not seem important to have so many types, each is a specialist in
terms of food, habitat, behavior, etc.  Each plays a role in ecosystems.
A great analogy for this is an engine.  If you pull one part out of an
engine, but don't know what it is - you wouldn't just throw it away.
You'd save it because maybe later you would understand it's importance and
use.

Another reason there is so much focus on polar bears is because they get
attention of the public.  They serve as a sort of "ambassador" species for
what's happening in the Arctic right now.  They serve as a gauge to
measure affects of climate change.

I know there are lots of opinions on this, but hopefully this is just a
start to get you thinking.

Essay on Global Warming: Polar Bears are Endangered

Essay Title: Polar bears are endangered
Polar bears are one of the countless species who are endangered. They were one of the first animals affected by global warming and their population is heavily decreasing. Around 1980, the Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the Arctic? Scientist predict by 2040, only a fringe of ice will remain in Northeast Canada and Northern Greenland. This is known as the Last Ice Area. This matter is mostly taking part in Canada, since; Canada holds more than half the world’s polar bear population. Other affected countries include the U.S. (Alaska), Greenland,…show more content…

This matter is mostly taking part in Canada, since; Canada holds more than half the world’s polar bear population. Other affected countries include the U.S. (Alaska), Greenland, Russia, and Norway (the Svalbard archipelago) .There are solutions to slow down global warming but unless we all act together, then there is no hope for the polar bear inhabitants of earth.
CAUSES OF THE PROBLEM
Polar bears are endangered animals as a result of the humans polluting their environment. Human hobbies such as hunting destroy polar bear population. Some cultures find polar bears as good sources of food. But, the leading reason behind polar bears endangerment is global warming. Global warming is destroying the polar bear habitat. Global warming is caused by humans but we are not making an effort to fix it. A lot of humans still do not even know what global warming is and should be aware of this issue. The main cause of global
