- Issues in cold environments
- Valuable resources attract development
- whales, seals and fish
- Minerals e.g. gold in Canada and Alaska
- Oil e.g. Prudhoe bay, Alaska
- Tourism e.g. Antarctica
- HEP
- Why are cold environments fragile?
- short growing season - difficult to recover from damage
- Plants & animals are adapted so cannot change if conditions change
- Low temperatures so pollution breaks down slowly
- How does development damage the ecosystem?
- Fishing : food chains affected, overfishing, bottom trawlers catch unintended species
- Oil: spills in transport & from pipelines cause pollution,
- HEP: blocks fish migration & heats up water
- Tourism: cruise ships causes pollution, roads & hotels can reduce biodiversity
- How has development affected the locals?
- Traditional peoples : Vuntut Gwitchin of Canada rely Hunting caribou, fishing,
- Many natives killed by newcomers diseases.
- Overfishing reduced number of fish for locals
- Young people forced to leave to look for jobs
- Traditional peoples : Vuntut Gwitchin of Canada rely Hunting caribou, fishing,
- How is development made more sustainable?
- National Parks:tourism whilst protecting the environment
- Fishing quotas
- oil pipes shut off valves to minimise oil spills
- Valuable resources attract development
