What are the three types of biodiversity?
Genetic
Species
Ecosystem
What are the three componenets of Sustainable Development
Environment
Social
Economic
What is the main driver for climate change?
The enhanced green house effect caused by excess greenhouse gases
Define renewable
It can be replaced as quickly as it is consumed
What are controlled variables?
List and define the four ecosystem services
Provisioning - Provides resources
Regulating - Air and water quality
Supporting - Nutrient and water cyling
Cultural - Recreational uses
Explain how to conduct a cost-benefit analysis
identify costs (financial, social and environmental)
identify benefits (financial, social and environmental)
Make a choice
List 4 greenhouse gases
Carbon dioxide
Nitrous oxide
Methane
Water vapour
list 3 renewable energy sources and 3 fossil fuels
solar, wind, hydro, tidal, geothermal
coal, gas, oil
When is an experiment valid?
When the data collected answers the aim
List five factors that effect Biodiversity
Mutation and natural selection
Inbreeding
Genetic Drift
Genetic Swamping
Extinction
Demographic Variation
Loss of keystone species
What are the four factors that are considered challenges to sustainability
Population
Food
Water
Energy
List three consequences of climate change
more extreme weather
rising sea levels
increased average temperature
Explain why a solar panel is more efficent than a coal fired power station in producing electricity
less energy transformations = more efficient
Explain the difference between the independent variable and the dependent variable
independent - what you change
dependent - what you measure
What is the difference between species richness and species diversity?
Richness is just the number of species where diversity also looks and the number of individuals of a species
List four key components of environmental management system
Risk identification and Assessment
Standards
Stakeholder engagement
Policies and procedures for monitoring and implementation
Name the three ways we measure and track climate change in the past and present
ice-core sampling
paleobotany
global air and ocean temperatures
describe two consequences for society when we reach peak oil
can no longer meet demand for fossil fuel
need to invest in infrastructure for renewables
when should you present your results as a line graph
when tracking a trend over time
List 6 threats to biodiversity
Habitat loss anfragmentation
Over exploitation
Small population (inbreeding)
Loss of symbiotic relationships
Bioaccumulation and Biomagnification
Climate change
Disease
Introduced species
List the 6 guiding sustaiblity principles
Conservation of Biodiversity and Ecological Integrity
Intergenerational Equity
Intragenerational Equity
Efficient Resource Use
User-Pays Principle
Precautionary Principle
Describe 3 ways that we can mitigate climate change
carbon sinks
reduce emissions
seek alternatives
Outline the three aspects of mine rehabilitation
mechanical - replace the soil
chemical - water, soil and air quality restored
Biological - biodiversity reintroduced
What five things should you include in your discussion?
the overall trend of the data
evidence of the trend
link trend to scientific concepts and understanding
Errors and evaluation
