The Polar Bear World Is Disappearing
The polar bear world is disappearing. Whether from the consequences of global warming or from infringement from humans and the pursuit for resources such as oil, the endangered polar bear is becoming a victim of our increasing environmental and economic pressures.
As it has been projected that by the middle of this century we will no longer have year-round Arctic sea ice, the polar bear may disappear from the wilderness. Climate change and thinning ice has already lessened, by several weeks, the time mother polar bears have to feed and store the fat that sustains them and maintains their young.
Many scientists believe that the rapid rate of climate change (global warming) taking place in the Arctic will create resonating consequences. In addition to suspected changes in ocean and atmospheric air patterns,[link widoczny dla zalogowanych], effects on the endangered polar bear is likely to be quicker and can already be measured in a thinning of the weight of polar bears and also in the birth and survival rate of the cubs.
Exceedingly sensitive to disturbances, oil exploration impacts the endangered polar bear in several ways. For instance, when oil exploration equipment drives too close to the dens, it sends shock waves through the ground as it searches for oil and gas reserves, making the polar bear mother abandon her den and her cubs, disturbing her hunting patterns. Since the cubs do not leave the den until they're 3 months old,[link widoczny dla zalogowanych], when abandoned, they will die.
It is known that 1 bear has died from ingesting a toxic substance,[link widoczny dla zalogowanych], due to the continuous release of contaminants from petroleum exploration,[link widoczny dla zalogowanych], production and support activities in active oil fields on Alaska's North Slope. That's 1 bear too many!
Although most Americans concur that there isn't adequate oil in the Arctic Refuge to compromise the loss of this place, its people and its wildlife, unfortunately the battle to protect the Arctic goes on in this, the polar bear world.
As more people move to these areas, they will acquire garbage and, of course, many polar bears will move in too near when looking for food, and be killed. The polar bear habitat is shrinking. Extinction of these peerless creatures, so unique in our world, is nearly a certainty.
The combination of pollution swirling to the Far North from sources thousands of miles away, along with oil development and global warming, could harm not only the polar bear world but also the entire ecosystem. Thinning sea ice, greenhouse gas emissions, climate change--these factors and more are affecting the future of this and countless other vulnerable arctic species. The endangered polar bear is perhaps our generation's "canary in the coal mine. " Its demise could forecast even larger environmental dangers to come. Polar bears are a national treasure, and their survival hinges on us!Topics related articles：
