· Significant indigenous population (Gwich’in and Impuit tribes) subsidence agriculture- depend on environment for food and supplies.
Resource exploitation
· Oil/gas extraction- Prudhoe bay, Northern Alaska
· Forestry and agriculture in the interior
· Fishing in Bering sea
Key challenges
Physical
· Below freezing temperatures
· Extremes of climate- warmer near coast
· Winds
· Climate change- increase melt of permafrost making land difficult to build on and lead to subsidence problems.
· Tectonic activity- high level of earthquakes
Human
· Waste disposal- slow decomposition due to cold temperatures
· Lack of daylight hours in winter
