WILL MAN MADE IMPACT BE FATAL IN ANTARCTICA?

Man has already proved that unchecked, unregulated exploitation of seals and whales have indirectly taken many other species of organisms to the endangered levels. This means, what constructive work nature did in millions of years, man was able to destroy just in couple of decades.

Today, with technological advancements, the danger to nature has grown to such an extent that man has been able to make estimates of minerals and oils, hidden by nature under the thick sheet of ice. If the mineral exploitation is permitted in Antarctica, it will not only load the environment with dust, it will also lead a large icy area to reduce its albedo. The reduce albedo will enhance melting of the ice sheets to such an extend that the sea level will rise more than 1 metre.
In fact, Antarctica is a fragile eco system of ice-air-ocean-energy, in which if one component is affected, all others will also be disturbed. Therefore, many countries try to protect Antarctic environment seriously, raise the issues of sovereignty, politics, logistical convenience, financial considerations, and the facilitation of scientific research. Environmental groups are, therefore, concerned about the scope of procedural and informational requirements for reviewing proposed projects and regulating development activities, especially in light of potentially large financial and political incentives associated with minerals development. Liability for environmental impacts from serious accidents is also an issue.

The way, world population is increasing, the hunger of the world for energy, food, water and other life support materials may modify the environmental treaty (Antarctic Treaty), in which, instead of maintaining pristine environment, only a practically clean environment may be maintained. This will be an extremely dangerous situation, as practically clean sampling and monitoring will not be feasible in such a harsh environment and thus the procedure will violate the treaties. The people who does not adhere to the protocols will be penalise and thus the conflict will erupt. Toady, the example at the world level is the pollution levels of various gaseous and solid pollutants in major cities which are often beyond the acceptable limits, yet nothing is done. Or many times, the monitoring approach remains only a paper work and nothing in reality is implemented. Often the monitoring and legal machinery is so corrupt that one is left to spoil the environment as much as one likes, just on the basis of economical power to grease the hands of these agencies.

If minerals development proceeds within the framework of the Minerals Convention, future debates will likely focus not on decision making procedures, but on the definitions of the Convention's many qualitative terms such as "adequate," "effective," "acceptable," "significant," "safe," etc. These terms can only be defined within the framework of scientific knowledge and uncertainties about Antarctica's environment.

Similarly, oil exploration, oil spillage from tankers, oil fires etc may deposit a thin film of crude oil seriously affecting the marine life and its entire dependent food chain. The third and the most critical factor which will affect Antarctica is the exploitation of Antarctic ice for meeting the need of world's drinking water for the growing population. As the world is witnessing the water shortage and the III world war to be fought for oil, water and food, will human start looking for pure, clean, ready to drink water from Antarctica? If so, who are responsible? Can we stop it? Or is it good to bottle water from Antarctica and serve it in the 5-Star Hotels?
