Q

How has the Trans-Alaskan pipeline been modified to fit with the environment?

A
  • built in a zig-zag so it can withstand movement from earthquake tremors
  • built above ground so it doesn’t melt permafrost
  • the flow of oil in the Trans-Alaskan pipeline can be shut down and isolated within 15mins if a leak or blockage is detected

Q

Advantages of the Trans-Alaskan pipeline:

A
  • can transport up to 1.4mil barrels of oil a day
  • revenue collected from oil means cities of Alaska pay reduced taxes
  • trucks can only pass Prudhoe bay 10 weeks of the years, it is too dangerous otherwise - the pipeline allows oil to pass all year

Q

How does industry affect cold environments?

A
  • cold environments have rich reserves of oil, gas and other precious minerals such as gold
  • oil and gas in particular are in high demand as a source of energy and countries are keen to exploit these resources, roads have to be constructed through forests and across the tundra and supply bases built
  • housing for 100s of workers also needs to be constructed
  • all of this can have huge impact on environment
