“POLAR
BEARS”
Polar
bears are at the top of the food chain and have an important role in the
overall health of the marine environment. Over thousands
of years, polar bears have also been an important part of the cultures and
economies of Arctic peoples. Polar bears depend on sea ice
for their existence and are directly impacted by climate change—serving
as an important indicator species.
How does climate change affect polar bears so
dramatically?
Polar Bear Specialist Group show that they are in decline and that there is a high estimated risk of future decline due to climate change. As their sea ice habitat shrinks from climate change, skinnier and hungrier polar bears face a grave challenge to their survival. Polar bears rely on sea ice to access the seals that are their primary source of food as well as to rest and breed. With less sea ice every year, polar bears and many other ice-dependent creatures are at risk. In most areas, they come ashore when ice melts and rely on fat stores until the ice refreezes so they can go back out to hunt. Some polar bears may suffer from malnutrition. In extreme cases—especially females with cubs— they may face starvation. Traditional prey species may be less accessible in a new sea ice environment, and seals that use the ice are predicted to fare poorly in the warming Arctic region. Climate change is also resulting in more habitat fragmentation. As Arctic ice melts, polar bears are affected by increased shipping activities and a rise in opportunities for oil and gas development. Other key threats include polar bear-human conflicts, unsustainable hunting and industrial impacts.
Conserving
habitat for Arctic ice dependent species and protecting the cultural heritage
and economies of local communities. So we have to sustainably preserve the rich biodiversity of this region for
example industrial development takes place, it is sustainable and does not
damage wildlife populations and ecosystems to any great extent. The
survival and the protection of the polar bear habitat are urgent issues. Your voice matters.
