Polar bear killed by HEATWAVE: Argentine animal dies after becoming ‘nervous and irritated’ amid scorching heat and noise

Comments Off on Polar bear killed by HEATWAVE: Argentine animal dies after becoming ‘nervous and irritated’ amid scorching heat and noise

“Posted on behalf of my mum”

The last remaining polar bear at Buenos Aires Zoo has died after overheating in soaring summer temperatures.

‘Winner,’ who was one of best loved attractions at the zoo, is believed to have been unable to control its body temperature in the extreme heat of the Argentinian summer and died of hyperthermia.

The animal, which was covered in heavy fur to cope with freezing conditions in its native Artic habitat, was also believed to have been frightened by the noise from fireworks let off to celebrate Christmas Eve

Tragedy: ‘Winner’ the last polar bear in Buenos Aires Zoo, Argentina, has died from hyperthermia in the soaring summer heat

The zoo is a popular visitor attraction in the Argentine capital and has a tradition of looking after polar bears.

The animals used to live in a pool but their cage was improved in 1993 when a 145,000-litre pool was built along with a site for birthing and three security rings.

The zoo said in a statement that it had been visited by experts and met all international regulations to house polar bears.

The polar bear is often regarded as a marine mammal because of the large amount of time it spends at sea.

Its preferred habitat is the annual sea ice covering the waters over the continental shelf in the Artic.

The animal is a very good swimmer with some spotted in the sea as far as 200 miles from land.


Hardy: Polar bears often spend as much time in the sea as they do on land as they hunt for prey

Polar bears cannot simply acclimatise to hot climates. Even if a polar bear is born in a warm climate and lives there all of his life, he will still possess several physiological adaptations to life in the Arctic.

Even if he loses some fur and blubber, he will always have black skin that absorbs heat and hollow hairs which work as efficient solar collectors.

Polar bears do not have any physical means of staying cool; they rely on behaviour to do that.

They will try to take as much shade as possible during the warmest parts of the day and cool off in cold water when they overheat.

Zookeepers may try and balance their energy expenditure and food intake to regulate their body temperature and may be fed a vegetarian diet or simply very little during warmer times (eating meat and fat generates immediate heat energy).

The bottom line is that polar bears can be resilient but this does not mean that they are comfortable.

Polar bears are found in the Arctic Circle and on neighbouring land masses as far south as Newfoundland Island in Canada. Some sightings have even been reported in the far north of Norway.

The bears are rarer in the extreme north of the Arctic although the animal is believed to roam across right across the region.

They tend to favour hunting on sea ice and in the sea in search of prey such as seals. Polar bears often frequent areas where sea ice meets water – primarily around the edges of the ice pack, where more seals can be found.

The global polar bear population is believed to be between 20,000 and 25,000 with 19 recognized sub-populations.

The polar bear is the largest terrestrial carnivore, with adult males weighing between 350 and 680 kg (770–1500 lbs) and measuring between 7.9 and 9.8 ft in length.

Slaughter of the survivors

Comments Off on Slaughter of the survivors

This year, climate change caused virtually all the sea ice in the Gulf of St. Lawrence to melt–long before it should have. So many of the baby seals have died already, forced into the water before they were strong enough to survive there. Unbelievably, sealers came here anyway to slaughter the remaining defenseless pups.

In a couple of weeks, the commercial seal slaughter will begin in earnest off the coast of Newfoundland and the Canadian government just authorized a record high quota of 400,000 harp seals. If we don’t stop it, so many baby seals could be killed.

Please help us end this slaughter of the survivors, donate today:https://secure.humanesociety.org/site/Donation2?9020.donation=form1&df_id.

Protect their Ice from Corporate Polluters

Comments Off on Protect their Ice from Corporate Polluters

A wild polar bear in the Arctic is a majestic creature–commanding respect with its beauty and ferocity. But global warming is threatening this bear’s very existence.

Polar bears in the southern area of their range are literally starving to death as the ice they depend on for hunting seals melts sooner in the spring and freezes later in the fall each year. Unless we act, polar bears could easily disappear from the Hudson Bay within our lifetime.

Polar bears are starving–take action to protect them today.

Right now, we have a chance to fight for these magnificent bears. The Environmental Protection Agency (EPA) is about to propose rules to limit pollution from coal-fired power plants, which are the largest source of carbon pollution in the U.S. By reducing the pollution they emit, we can make a substantial impact in the fight for polar bears.

But, even as polar bears go hungry from the impacts of climate change, greedy corporate polluters are fighting to keep dumping unlimited carbon pollution into our air.

Don’t let corporate pollution starve polar bears to extinction–send this message today.

For thousands of years, polar bears have made the Arctic their home. The expansive ice and plentiful seal populations have shaped this species. In just four decades, the number of ice-free days polar bears face in the western Hudson Bay has grown by 40 days in just the last 40 years to a terrifying 160 days in 2010. That’s 160 days without access to food, while they are nursing young.

Polar bears do have hope of surviving into the next century if we act now to reduce one of the greatest emitters of the carbon pollution that is melting their ice.

Help create a better future for polar bears–take action to slow the pace of global warming.
