Polar bears resort to cannibalism

Wow, this is so misleading in regard to anything, yes EVERYTHING about a polar bear.

OK... here is POLAR BEAR 101:
The "starving and cannibalism" is referring to a typical behavor of a lone Male Polar bear.

These lone male bears will eat any cub they can catch and if the mother defends the offspring enough, they will attack her as well.

Their goal in attacking the cubs is for the female to come into estrus and allow the male to sire cubs with said female bear.
Lions do the exact same thing.

THIS HAS NOTHING TO DO WITH MELTING ICE.
IT IS CALLED MATING. POLAR BEAR STYLE. YEAH IT'S UGLY. LOOK AWAY.

In fact, polar bears do most if not ALL of their hunting in the water. They typically swim aprox. 60 miles a day. Some are known to swim more. They do walk alot on the ice, but that is usually to GET TO the WATER.

No they are not drowning. OMG that is truly funny. Did you know they can bring down beluga wales? They are far from helpless in the water.

Of course seals are their first choice, and they too are found in the water, and swim at great speeds... so does the bear.

To the authors of this article: Please read a book about bear behavior!

Does anyone know why the bears have a life on the ice in the first place?

(WARP IN TIME>>> POLAR BEAR HISTORY 101)
Their once lush landscape (during parts of the year) eventually became frozen all year as it has been for a very long time...
So, the once grown bears how to adapt and evolve to survive on the desolate surface of ice, that they suddenly had to call home. THAT was a crisis, actually.

The bears couldn't eat the herbs, vegetation and the death of everything in their food chain due to the complete ice that for their natural diet. The originally brown bears over time became what we call polar bears.

What happens if the ice melts? Massive death of bears?
NOT HARDLY!
To claim, however, that they are facing imminent doom is stretching the truth. In 1950, let us not forget, there were about 5,000 polar bears. Now there are 25,000.

Probably they will have a better diet in the summer.
We will eventually see higher birth weights of cubs as the bears adapt to any climate changes.

FEAR SARAH, that is the true reason for this "crisis"
Don't worry about the bears, they survived the first crisis that froze their homeland, this should be cake.

Why is this political?
First there came the computer-generated polar bear in Al Gore’s An Inconvenient Truth; then that heartrending photo, syndicated everywhere, of the bears apparently stranded on a melting ice floe; then the story of those four polar bears drowned by global warming (actually, they’d perished in a storm).

Now, in a new cinema release called Earth – a magnificent, feature-length nature documentary from the makers of the BBC’s Planet Earth series – comes the most sob-inducing “evidence” of all: a poor male polar bear filmed starving to death as a result, the quaveringly emotional Patrick Stewart voiceover suggests, of global warming.
