Pollution and Culture in Greenland :: Greenland Environment Ecology Pollute Essays
Greenland is contaminated with considerable amounts of pollution, caused by large-scale atmospheric circulations, especially in winter. The pollutants in the Arctic are primarily sulfur, which is highly acidic, in both gas and aerosol form. Most of these pollutants are from anthropogenic sources deriving mainly from industrialized areas in the Eurasian continent. In addition to threatening environmental stability, pollution is speeding the unraveling of traditional Inuit culture in Greenland. Climate change is affecting the entire world, yet Greenland is especially sensitive to slight fluctuations due to its dependency of the nativesââ¬â¢ traditional lifestyles on the environment. Melting ice and permafrost restrict access to hunting grounds making a traditional way of life consisting of hunting seal and caribou more difficult.2 Every four years, the Inuit living in Greenland, Canada, Alaska, and Siberia convene the Inuit Circumpolar Conference (ICC) to discuss issues of concern. The ICC lobbied successfully to ban a dozen organic pollutants, carried north by winds, that do not evaporate in the Arctic cold. These pollutants were infecting meat and berries, staples of the Inuit diet, as well as the breast milk of nursing mothers.3 There are many more problems facing the sustainability of Greenland, such as trans-boundary pollution and the fact that the Inuit are not an effective lobbying group due to differences in culture, dialect, and lack of communication. In November of 2004, a report by 250 scientists warned that the Arctic is warming twice as fast as the global average, which threatens to wipe out several species including polar bears, and melt summer ice around the North Pole by 2100.4 One of the reasons for the increased warming is that the dark water and ground in the arctic soak up more heat from the atmosphere than ice or snow. The levels of carbon dioxide today are about 379ppm and increasing, a comparable level to 55 million years ago when there was no ice on the planet due to the warmth of the atmosphere.5 If the Greenland ice cap melts, the sea level will rise six or seven meters. Although this is a worst-case scenario, it seems clear that steps must be taken to reduce the concentration of carbon dioxide and other pollutants in our atmosphere. Investigations of pollutants in Greenland during the past fifteen years show that the troposphere is burdened with high levels of trans-boundary pollution. The major anthropogenic contributors to this ââ¬Å"Arctic hazeâ⬠are central Europe, and northern Russia.
