exams Flashcards
terrestrial food systems influencing climate, and climate influencing them
meat diets - bad for envrionment
veg - soil degradation
adaption - water conservation
mitigation - localising food production
not sustainable, aiding climate change
two transformations of matter
evaporation condensation
two transfers of energy
chemical, radiation of heat
Hadley cell
four impacts of invasive species
intro to new disease
increase diversity
reduction in plant species causing a reduction in productivity
higher trophic levels
positive feedback loops for population growth
population increases
increase number of reproducing individuals
growth rate increase
negative feedback loops of population growth
occurs as they approach carrying capacity
limiting water availability, reduces growth rate
stabilising population
procedures carried out abiotic and biotic impacts of oil spill
- transcet or sampling scheme
multiple samples
oil concentration
light penetration
oxygen
mark release capture
lincoln index
total killed
point vs non-point pollution
point pollution - specified pollution in one (small or large) area - like an oil spill
non point is when it comes grom everywhere like GHGs
EVS
refers to world view and shapes the way an group percives envion issues
natural capital vs natural income
all of the things that hold value in an environment or given area
all of the things you can get
vs the value one thing has in an environment - like wood
what is the purpose of an EIA and what is it used for
helps decisions by providing information abt the environment and evaluating what solutions are the best
steps in EIA
- identify key issues
- document characteristics - biodiversity etc
- value systems of local population
- impacts on society or ecosystem
- review to make better chnages
EVS inputs and outputs
inputs - education, experience, media
outputs - decisions, actions, policies
