The region is a rather pristine, polar desert environment, and significant gaps in knowledge exist on how this landscape will respond to increased human activity. The arctic, earth’s northern polar region, is an ocean surrounded by land snow and ice cover much of the arctic land and sea surfaces, particularly at the far north the southernmost part of the arctic, which includes the northern part of north america and eurasia, is covered by boreal forests , separated from the icy north by a wide expanse. The arctic region is an exporter of raw materials and energy and an importer of final goods and services since their arrival in the arctic, the indigenous peoples have lived from the renewable resources of the sea (fish. An integrated european union policy for the arctic 2 joint communication to the arctic region7 for example, the eu is a major consumer of products coming from the arctic states, such as fish products and energy8 investment by european companies can help increasing human activity in the region. The human activity most widely viewed as changing the planet is the burning of fossil fuels in order to produce the energy that drives the world’s economy, countries.
Climate change caused by human activities is by far the worst threat to biodiversity in the arctic some of these changes are already visible unique and irreplaceable arctic wildlife and. The majority of the arctic is composed of the arctic ocean which was formed when the eurasian plate moved toward the pacific plate thousands of years ago although this ocean makes up the majority of the arctic region, it is the world's smallest ocean it reaches depths of 3,200 feet (969 m) and is. The ongoing loss of arctic sea ice has implications for marine shipping, tourism, oil and natural gas production, arctic residents, and international politics shipping routes once europeans encountered the north and south american continents, they began seeking a shortcut between europe and asia.
The arctic has an undeserved reputation as being a desolate, lifeless, inhospitable place in fact, the arctic regions of alaska, canada, greenland, northern scandinavia and siberia are the home for a number of indigenous peoples. While the severe weather prevents most people from living on the tundra, pollution problems from human settlement is severe in their local region traditional methods of sewage treatment do not work in the cold environment. The clean air, water and ice of antarctica are now of global importance to science for understanding how the earth's environment is changing both naturally and as a result of human activity tourist operators are beginning to tap into the huge demand to visit the last great wilderness on earth. Human activity has also exercised a strong influence on the wildlife of arctic areas polar bear , walrus , musk ox , and caribou all have been greatly reduced in numbers through hunting the danger was recognized, and protective legislation has been approved (international agreement on protection of the polar bear , achieved in 1973, was a. Human activity does not affect the amount of water vapour in the atmosphere to any significant degree as air warms, however, it can hold more water vapour of course, there is a limit to the amount of water vapour that the atmosphere can hold.
The arctic ocean is a vast maritime region which is bordered by six states that are now coming to the arctic is essentially a closed-sea and all human activity, even environmental accidents on land, unconstrained foreign direct investment: an emerging challenge to arctic security 1. Oil spills can kill wildlife and significantly damage tundra ecosystems buildings and roads put heat and pressure on the permafrost, causing it to melt invasive species push aside native. Questioning activists’ argument of human induced climate change nevertheless, in spite of the increasing arctic region arctic warming has major worldwide storm activity, inundation and. How humans deal with and survive extreme cold the body diverts blood flow from the surface as the temperature drops so the most important parts stay warm the longest this allows the body's core to be protected for longer.
The arctic climate impact assessment has proven that global warming is a danger that needs to be dealt with now and that the global warming crisis is aggravated even further by human activity. In alpine tundras too, climate warming could encourage more human activity and increase damage to plant and animal populations there the fate of permafrost in a. Human activities contribute to climate change by causing changes in earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness the largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.
In the past, human interaction with nature, although often having a disruptive effect on nature, often also enriched the quality and variety of the living world and its habitats - eg through the creation of artificial landscapes and soil cultivation by local farmers. Even in remote areas, far from any human habitation, unwelcome encounters with rubbish and industrial and military waste are reminders of the fragility, brittleness and vulnerability of the arctic, and of the intrusive nature of human activity. Increased transport and industrial activity in the arctic will increase contaminants levels, while melting ice, thawing permafrost, and degrading glacial snow may release legacy pollutants (pops and metals) from past human activities. Sea ice in the arctic region, formed from frozen seawater, has shrunk dramatically in recent years and could reach a new record low this summer experts said this week that this year's ice melt.
