World running out of time to save polar bears.
Polar bears are widely(ampliamente) being associated as the clear negative sign of
ongoing(continua) climate change phenomenon. The rapid changes in sensitive Arctic
environment, mostly characterized by the ongoing ice cover loss are
having devastating impact on polar bear population, and could even lead
to the extinction of species, even before the end of this century if
world continues business as usual scenario. In most simple words, polar
bears need sea ice, and since sea ice is rapidly declining, the bears
are in very serious trouble.
The worst part in this whole story is that the world still hasn't come
up with the adequate conservation and management plans to save polar
bears from extinction, and climate change threat is becoming scarier
with the each new day.
Scientists from University of Alberta have described the seriousness of
polar bear situation by saying that ``just one very bad ice year could
erase half of the world's polar bear population``.
The world definitely does not know what to do if the worst-case scenario
occurs. The expected continuation of Arctic warming will not stop just
because we want to, and will certainly not stop without the major global
reduction in greenhouse gas emissions.
What kind of polar bear management option would be the best? Difficult
to say, particularly if world fails to reduce the level of greenhouse
gas emissions in foreseeable future.
At this moment, the most important thing is to think and act about this
issue in advance, because the worst possible thing is to act once crisis
already starts. Though as some would say crisis has already started.
