8.2 resource use in society Flashcards
economic natural capital
- fossil fuels, timber, food crops, gemstones
- have economic value and can be sold on the global market
- no value in a society that doesnโt use money for its economy
aesthetic and intrinsic natural capital
- stream, mountains, meadow
- appreciation for natural beauty
- brings wellbeing and inner peace
- value simply because it is there
- subjective to the individual
cultural and spiritual natural capital
- famous religious buildings, ancient sites, monuments, spiritual places for indigenous people
- only valuable for certain people
environmental natural capital
- the environment provides all other capital
- different opinions on what should be done
natural capital and technology
- value of resources changing over time
- current devices useless in the future
non-renewable natural capital
- how long it takes to replace vs how fast we use it
- geological time scales to form, irreplaceable in our lifetimes, finite
case study
soil degradation: sub-saharan africa
- poor soil management, accelerated hunger crisis, more than 240 million africans impacted
- crop yields falling, more dependent on outside aid
- savanna being lost, impacting habitat for wildlife and tourism
- farmers dependent on agriculture for income
causes of soil mismanagement
- abandonment of traditional farming methods, soil not time to recover rapidly growing populations
- topsoil lost to wind and water erosion
- no money for fertilizers to replenish nutrients, more expensive in africa
solution
green revolution
- aid workers to teach farmers methods to improve agricultural productivity
- better road networks to travel to remote areas
- credit farmers to pay for better seeds and fertilizers
- better irrigation
- make fertilizers and seeds needed accessible and affordable, better roads
- combating corruption of officials trying to take funds for personal gain
renewable natural capital
living
- all living species
- use solar energy directly or indirectly to regenerate
- must be carefully/sustainably managed
- treated wrong can destroy and remove the source
renewable natural capital
non living
- renewable energy resources, remain unchanged no matter how much we use them, canโt be used unsustainably
- water resources, impacting the hydrological cycle, polluting bodies of water, over extracting from groundwater
- ozone, we donโt directly use it but we are managing it unsustainably causing depletion
tragedy of the commons
- over harvesting renewable natural capital to the extent it is no longer renewable
- individuals acting in their own self interest, not in the interest of the group
case study
collapse of the newfoundland cod fishery
- lots of cod
- small boats and traditional fishing methods, allowed replenishing of cod stocks, sustainable
- delicately balanced ecosystem
- technological advancement, trawlers, large nets, froze out at sea, not needing to return home as often
- government ignored warnings to reduce fishing quotas
- government supported big corporations to maximize revenue at the expense of local communities
- catching too many, cod catch declining each year, complete collapse in 1995
consequences
- still not fully recovered
- 42,000 people lost jobs
- small communities left as their livelihoods were gone
