Is it true that all polar bears are going extinct? (please say why)?

Question

my friend says polar bears are going extinct and i love them so much ! but she never told me why i have a feeling she was just trying to make me scared or sad is it true?

Answer 1

Yes, it's true. The culprit: melting ice, or to be more precise global warming, meaning humans. The ice cap is shrinking at an incredible rate. They are drowning because they can't swim that far (400 miles).
How global warming works:
Humans release carbon dioxide and other greenhouse gases that trap most of the heat into earth. This makes the planet warmer. This melts the ice at the arctic. Ice has a high albedo, meaning it reflects a lot of sunlight back into space. This creates more water for the sunlight to hit. Water has a much lower albedo. When sunlight hits the water, it makes it warm melting more ice and creating a positive feedback loop. As sunlight melts more ice, there's more water to hit and it warms up melting more ice.

Sorry, your friend was telling the truth.

Answer 2

I don't think they are going extinct as such. There are reports, however, that they are drowning in large numbers. You've probably seen on TV how they love to swim in the open ocean waters. Well, the people who are watching the global warming issues have noticed that as the earth gets a great deal warmer, and as the huge ice chucks fall off the glaciers, the bears will get on the chucks of ice like they used to do but the ice breaks even smaller and the bears float out into the open seas on the ice - and far too far for them to swim back to shore. That is why many of them are drowning. I have been on two cruise ship rides on what is called the "Inside Passage" through Alaska. The two trips were just almost exactly 5 years apart. When we went into Glacier Bay the first time I was amazed at the enormous cliffs of blue colored ice. (It is that way because of the oxygen in the ice when it freezes quickly.) Five years later there was hardly any blue left in the ice cliffs and the cliffs were so much smaller that I was shocked. The first trip we saw many bear (not polar bears though) and seals floating on pieces of ice. The second trip there were hardly any. If I hadn't seen it myself, I wouldn't have believed it. I think this is what your friend was talking about and I hope this answers your question. Now, with this information comes the responsibility - how can we all save our planet from global warming?

Answer 3

Polar Bears are going to face a tough time in the next few decades. Their feeding is based on the size of the frozen ice shelf in the northern oceans. These are decreasing, meaning, freezing later and thawing earlier as well as decreasing in size. Is this Global Warming.......well that's for another question.

The short of it is that I think it is going to depend on us. I think that the Polar Bear population is definately going to decrease. However, it is an intelligent mammal and has the capability to adapt. If we do not interfere with this natural occurance, I think that the Polar Bear will do OK, albeit, it is going to become increasingly rarer in the wild.

I too, am a fan of the Polar Bear, and it's demise would be a great loss for me, but more importantly, for the planet, as it is a top predator. One that the arctic eco-system cannot afford to lose.

Answer 4

Global warming is melting the ice that polar bears live on. It's getting too warm for them, too. They're not built to live in warm climates. I'm sorry, but it's true.

Answer 5

it is true because the nature of the world is changing . the ice is melting and they dont have as much to eat . it was on planet earth the special series on the animal planet . It is true i am afraid . good luck .

Answer 6

the north pole is going exstinct ,and that is where the polar bears live.
but there will be many in zoos.

Answer 7

Yes, because its getting to cold for them.
