Living in the frozen Arctic, polar bears, a beautiful but highly endangered species, mostly subsist on seals, hunting them from platforms of sea ice. The melting of sea ice, warmed by rising global temperature, has deprived them of the platforms, particularly in their southern range, the Hudson Bay being a part of it. Now, mostly land-bound, hunting seals have become difficult for them leading to malnourishment and starvation. Cases of drowning are also being frequently reported as the bears, though excellent swimmers, have to swim far out into the sea in search of food. If this is what is happening in December, which is well into the Arctic winter, one can imagine what's going to happen during the summer. Already the sea ice in the southern range of the Arctic is melting earlier in the spring and forming later in the autumn reducing the time available for the bears on the ice, adversely impacting their energy stock to survive through the summer.
The entire Arctic region, which is the habitat of polar bear, is increasingly showing signs of the effects of global warming. As recently as on 14th December 2009 Al Gore, Nobel Laureate and former Vice President of United States, told the UN Climate Conference being held in Copenhagen that new data suggests that the Arctic polar ice cap may disappear in the summers as early as five to seven years from now. Polar scientist had told him only on the previous day that the latest data suggest a 75% chance of the entire polar ice cap melting in summer within the next five to seven years. Arctic Ocean sea ice has shrunk to record low levels during the past several summers. Global warming has raised temperatures twice as fast in the north as elsewhere, say the scientists.
While the Hudson Bay habitat of the polar bear is in the process of disappearing, their habitat elsewhere in the Arctic is also under threat. Melting ice is making the Arctic more and more accessible for exploitation of its vast natural resources, threatening and degrading their habitat. Global warming seems to have got its first major victim. Large carnivores being sensitive indicators of the health of their ecosystems, cannibalism setting in among the polar bears is a matter of great concern. Soon it may lead to disaster for the species, even to its extinction.
With the unmistakable signs of habitat loss for other species gradually a similar fate is likely to overtake them all ...yes, even us, humans!
One wonders whether this is really it – the shape of things to come!
Whether bells are, after all, tolling for life on earth!
Are we slowly but surely approaching apocalypse?
And, what are we, humans, doing about it? Only quibbling – over steps for mitigating carbon concentration from the atmosphere! Sitting at Copenhagen, pretty close to the melting Arctic, leaders of humanity do not seem to see eye to eye even now for taking effective measures to save the earth! When life on the planet is in peril, we, the humans, having divided ourselves among several nation-states – few rich, many poor and some surviving on the very edge and highly vulnerable – are bickering over who will do what and how much to cool the planet to make it hospitable for life.
Time seems to be running out fast. Global warming, which only a few years back was like a distant clap of thunder, suddenly looks very real and far too ominous. It is time each one of us gets our act together to fight it and do our utmost to prevent it from engulfing the entire humanity. The signals are loud and clear and there is hardly any time to be lost. No longer can it be "business as usual". Copenhagen or no Copenhagen, all of us – governments, organisations and individuals – have to chip in. Everyone has to take well-measured determined steps, whatever the costs, for mitigating carbon from the atmosphere – the root cause of global warming.
It is a long and hard battle that we have to fight – the battle that will eventually decide whether we survive or perish!
