Case study- Alaskan tundra
· Contains world’s 4th largest glaciated area, 40% of USA’s surface water, largest fisheries, wilderness areas and land designated for parks, reserves and wildlife refuges.
· Large oil/gas reserves
· Significant indigenous population (Gwich’in and Impuit tribes) subsidence agriculture- depend on environment for food and supplies.
· Oil/gas extraction- Prudhoe bay, Northern Alaska
· Forestry and agriculture in the interior
· Fishing in Bering sea
· Below freezing temperatures
· Extremes of climate- warmer near coast
· Climate change- increase melt of permafrost making land difficult to build on and lead to subsidence problems.
· Tectonic activity- high level of earthquakes
· Waste disposal- slow decomposition due to cold temperatures
· Lack of daylight hours in winter
