25
Medicine in rainforests
25% of medicinal plants and 2000+ anti-cancer property plants
26
Reasons for deforestation
Logging Mining Settlement growth Cattle ranching Road development Hydroelectric power Subsidence farming Commercial farming
27
Impacts of logging ( paid to cut down trees )
Provides resources - cuts down trees
28
Impacts of mining ( obtains minerals )
Provides resources Improves technology Generates money Scars landscape
29
impacts of settlement growth ( clearing space for housing )
Gives housing for locals Doesn't allow tree growth
30
Selective logging - rainforests
Plants as many trees as cut down Minimises soil damage Mimics natural processes More animals due to new growth
31
Education of deforestation - rainforests
Ensures those involved in the exploitation know the consequences Disencourages Prevents exploitation
32
Debt reduction - rainforests
Debt is wiped in exchange for protected rainforests Stops deforestation Forests remain intact
33
Adaptations of plants in rainforests
Buttress roots - support tall trees, transport water, increased SA increases O2 and CO2 exchange Lianas - grow towards canopy towards the light Drip tips - allow rain to drip off leaves Flexible based leaves - turn to face sunlight
34
Features of polar environments
High air pressure Sun rays have to travel further Temperatures below -50 Permafrost
35
Adaptations of a polar bear
Acute sense of smell Closable nostrils Oil based fur Large dimpled feet White translucent fur Layers of thick fur and fat
36
Features of a tundra environment
Temperatures to -20 Brief summers Precipitation in coastal regions Permafrost Infertile waterlogged soil Birds and insects abundant
37
Plant adaptations in the tundra
Shallow root system - allows plant to grow in the active layer and avoid the permafrost Grow in close proximity - each plant acts as a barrier to wind and ice Small leaves - conserve water and prevent loss from leaf surface
38
Transalaskan pipeline
Needed to reach oil store in Prudhoe Bay Zigzag to prevent breakage in earthquakes Flow can be stopped in 15 minutes if there’s a leak Can transport 1.4 million barrels of oil a day Could cause permafrost to melt and therefore pipeline is raised in stilts
39
Challenges in Svalbard

40
Opportunities in Svalbard

43
Tourism in Svalbard
Ship damage Risk of damaging sea life Underwater noise Oil spills
44
Methods to maintain Svalbard
Government action Protection Limit machinery Conversation groups International agreements Technology •Homes built on steel pilings Move buildings to safer areas
