biogeochemical cycles
Cycle of matter - the movement of elements between organisms, the atmosphere, and the earth’s crust.
- life + earth + chemical cycling
Carbon cycle
root respiration + animal respiration + human emissions = C02 = photosynthesis. organic life dies - decomposition - fossils/fossil fuels - human emssions - repeat (see image)
Nitrogen cycle
fixation - fixing bacteria - nitrifying bacteria - Assimilation or Dentrification - repeat (see image)
carbon budget
How much carbon humans can emit while keeping the global warming under a specific limit
planetary boundaries
- tipping points
- thresholds
- regime shifts
- resillience
9 planetary boundries that if we cross will move us into the anthroprocene.
tipping points = crossing thresholds tips to regime shifts (shit hitting the fan)
Thresholds = threshold of what will destroy everything
regime shifts = structural and functional change of ecosystem (amazon rainforest changes to savannah)
Resilience = how well boundarie can bounce back to how it was previously and recover
Antropocene
unofficial geological epoch marking the begining of significant human impact that can be measured in earths rock layer. Marks a new age where humans fuck up beyond repair and cause significant changes.
geological epochs (how are they formed)
long period of time characterized by great change, measured in rock layer of earth
common goods/common resources
- Open access and difficult to exclude access, for instance ocean
- no one owns them
- resources are finite. “Space”
i.e = ocean + fishing
Brundtland report/model
- big dick daddy of sustainable development
- 1987
- warned that shit was about to hit the fan
- developed guiding principles for sustainable development
- stressed maintaining economic development that doesn’t destory the planet
- “meeting the needs of the present without compromising the ability of future generations to meet their own needs”
- linked environment + development for the first time
tragedy of the commons
Individuals believe that it does not make a difference if they change because nobody else is changing, but everyone is not changing because they think nobody else is changing
logic of the commons
- Common resources are nonexcludable but rival
- people only think about themselves and they believe they their reduction of pollution is so little that they do not change anything
- Only think in short-term planning and not about the future
i.e = nobody is excluded from fishing, but all fishermen are rivals
GDP + GPI
gdp = Gross domestic product
- bad for measuring sustainable development
- measures uneconomic growth + economic growth
GPI = Genuine progress indicator
- social indicators, environmental indicators, economic indicators
uneconomic growth
Economic growth that is bad for the economy and society
- i.e = american healthcare system
doughnut model
Model that balances how we can meet our human rights whilst keeping the planet alive
innerboundary = social needs/human rights
Outerboundary = ecological ceiling
STAY IN THE FUKING DOUGHNUT
deposition
shit is depoisted
geological deposition = sediment over time is deposited to form a new layer of earth marking geological epoch
nitrogen deposition =
