- Increasing
Why is mining difficult on Svalbard?
- extreme cold
- long hours of darkness in winter
- challenging sea conditions
- remoteness
What conflicts does Svalbard’s mining company face?
Conflicts with environmentalists about the impacts on the fragile environment.
How can scientific research cause environmental problems in Svalbard?
Construction of the associated infrastructure and increased number of visitors.

+ Provided jobs to boost local economy
+ growth of services
- Oil spills
- waste discharges from ships
- air pollution
What example of past climates occurred between 1550-1850?

Check pastpaper - goude
How has tourism benefited the lake district?
- benefited the local economy by £1.1 billion
- better public transport and roads
- 16,000 jobs
- multiplier effect
How has tourism negatively impacted the lake district?
- Footpath erosion
- Trampling/littering
- Congestion
- Seasonal jobs
- An increase in demand for housing has driven up house prices so local can no longer afford to buy homes where they grew up. Lots of which are being used as holiday homes.
Why is footpath erosion a problem in the lake district?
- Destroy vegetation
- Reduce infiltration
- Small streams may form increasing soil erosion
How is climate change affecting the lake district?
- Loss of indigenous plant species
- Increase in non-native species (food chains)
- Movement of habitats from lower to higher altitudes
- Increased rain (Flooding, soil erosion, pesticide run off)
- Increase in insect species
What are the key players for the lake districts future?
- Lake district national park authority
What threats does the Sagarmatha national park face?
- Climate change
- Tourism (over 37,000 visited in 2014)
What threats does tourism pose to the Sagarmatha national park?
- Footpath erosion
- water pollution
- waste disposal problems with tons of litter being left
- a greater demand for forest resources such as wood
- increase in demand for roads, hotels and lodges causing deforestation (less than 30% remains)
What is the main threat posed by tourism?
Litter, frozen faeces and gas canisters
