Lately, thousands of â€Å"green† organizations have been generated to promote the green habits and to try to reduce pollution worldwide, reducing also the vulnerability of the tundra biome. Their projects consist in reducing wastes of any kind of energy source and saving any resource we get. This will involve social aspects also in the way that our society must take part and have an impact into world pollution, which will finally affect the tundra ecosystem; it has lately become popular to be ecofriendly. This ecologic movement has also affected the fashion industry which lately looks for looks with more pure materials, not much synthetic ones, also they’ve preferred clothing with pure cotton, even not only the materials of clothing are involved but the message in the clothing’s have taken a very special impact in the society. Hunting, affects directly and indirectly to the ecosystem of the Arctic wolf, it affects the interaction of living organisms by hunting the animals. The overhunting of species such as the musk ox and caribou in Alaska and North America were even near of extinction. This would create unsustainability on the ecosystem because there would not be equilibrium in the food chain and all the animals that have any relationship with the specie would me affected by don’t having a predator or a prey. Hunting in the tundra has had a very negative effect because important species suck as the musk ox have nearly got to extinction. By 1950, herds in North America were reduced by ninety percent, so this made the American population realize what was really going on in their country. They were loosing biodiversity and so laws were created to protect animals. This had an economic impact, because musk ox’s (prey of the arctic wolf) leather was part of the market so it has also a social impact, not only from for hunters but for the fashion industry which had a relation with musk ox’s fur and leather. Chemical contamination also affects the Arctic Wolf’s ecosystem. Lately, Petroleum and Coal or Natural Gas, Iron, Lead or Zinc mines and mineral exploration and exploitation and extraction are increasing worldwide especially in the Arctic. The development affects the Caribou, which are one of the main species present in the Arctic wolf habitat. Overdevelopment indicates to the building of roads and buildings in the tundra, this lead to more circulation. Fragile tundra areas of plants are taken out for the creation of these roads. Without plants to give nutrients to the soil, earth will stop being rich and will abolish the community of flora in the tundra. After discussing all the direct and indirect human impact in the environment, hunting, chemical contamination and overdevelopment are certainly harmful for the ecosystem. These activities attempt to the balance of the ecosystem by attempting against the living organisms that live in the tundra, ecosystem of the arctic wolf and by attempting against the non-living factors in the ecosystem such as climate. Even tough there are solutions for these activities to reduce or to stop, they are not completely efficient. In my opinion after all my investigation, apart from the pollution affecting indirectly to the tundra, the other activities are not a major concern for the arctic wolf’s ecosystem. As seen, human activities impact in the arctic wolf’s ecosystem is not positive (although they don’t damage much the tundra) toward the ecosystem. My final conclusion will be that external factors are definitely against the equilibrium of the arctic wolf’s ecosystem.
