With reference to a named example, explain how careful management can help to achieve sustainable development in cold environments. Arctic tundra is often very flat, cold and windy.  Much of the ground is permanently frozen and the air is very dry.  In fact the tundra is a type of cold desert.  The temperature of the Arctic tundra varies from about 10oC in summer to -40oC or below in winter.  These conditions mean that there is little food for animals to live on, so the Arctic tundra can only support a small number of species. These environments are being managed sustainably. Sustainable development is development that meets the needs of the present, without compromising the ability of future generations to meet their own needs. Many cold environments are extremely fragile and have fragile ecosystems. In places such as the Arctic National Wildlife Refuge, Alaska. This part of Alaska is federal land, owned by the us, and contains high quantities of oil and gas. New environmentally friendly technologies for oil and gas have been developed, the conservation is taking place though methods such as drilling laterally beyond the drilling platform, and new drilling techniques allow oil and gas deposits to be accessed several km away from drilling rigs. This means that less space is used, meaning smaller amount of habitat is destroyed. Insulated ice pads, roads and other infrastructure, therefore this is reducing risk of melting the permafrost. And also more powerful computers can locate oil and gas underground. The people living in this area, the Gwich’in, are also affected by the development and intervention of the US to drill for gas and oil. A pipeline has been set in place along a grazing pattern of the reindeer, they are unable to jump the pipe, so graze up and down it, over grazing this area which is already fragile. This causes minimal food for the reindeer often causing death. This affects the Gwich’in population as they rely on the reindeer to survive, they...
