Polar bears face three main challenges, including global warming, pollution, and hunting. Melting ice due to global warming makes it difficult to find seals to eat and make dens, while pollutants make their way up the food chain to polar bears.
There are many life challenges for a polar bear, such as:
Polar Bears are very vulnerable to climate change and human hunting. Due to their sheer size, they have no natural predators except themselves. Large males have been known to kill off younger/smaller bears to cut out on competition. Man has been hunting these giant carnivores for centuries for its skin and fur. As of now, approximately 20000 to 25000 animals exist in the Arctic wilderness. Their numbers are steadily declining due to habitat loss and hunting. Oil and Gas exploration in the Arctic too is a significant cause for the decline in Polar Bear numbers. Due to human activity and global warming, the ice caps are melting. So, the effective land that the bears have for hunting is coming down. Pollution too is killing off prey species. So, everything put together is endangering the species.
Global warming , the icecaps melt and brake a part from the main n-pole and go at sea , polar bears have been known to stay on them for weeks before eventually drowning
People and global warming is a threat to polar bears.

mother nature and mostly man kind because we are the ones who are causing global warming
hunting was a problem but now the species is better protected.
The environmental conditions that polar bears face are that due to global warming
which is created by methane gases from animals such as cows and the noble gases that are trapped in our atmosphere so when the sun rays go down to earth then leave the rays get trapped in our atmosphere which creates an insulation on the earth. The sea ice is melting from global warming. We can help by using public transport and cutting down on waste also turning off electronics and not leaving them on standby. Hunting from humans who eat their meat and liver. There is too much carbon dioxide in our atmosphere which causes global warming.

Mainly that their environment is melting.
I can answer your question better if you rephrase it.Do you mean what threatens Polar Bears or what kind of threats they have to us?If you mean what threats do they have to us then ...they have the same threats as another kind of bear. If you mean how do we threaten well there is an endless list.We threaten just be entering their territory.Global Warming and Testing also threaten them.
The polar bear is not an endangered species, but listed as vulnerable, in spite of the fact the population is four times what it was in 1970. Hunting, which is rare now, and suspected loss of sea ice are threats.

why does the polar bear helps the polar ice
The grizzly or brown bear and the polar bear are basicly the same size.
The Polar Bear.
The Polar bear is the biggest bear.
just like human do .
Nothing. A polar bear will eat you.
no
Polar bears are bears
A polar bear.
