| Question | Answer |
|---|---|
| Sustainability (def) | Used to describe developments that meet the needs of today, without compromising the ability to meet the needs of tomorrow |
| Ecological Sustainable Development (def) | Term which applies to every aspect of living in a sustainable way |
| Resource Conservation (def) | The protection and management of natural resources with a sustainable view, especially non-renewable resources. |
| 3 conditions of Sustainability | 1) Renewable resources should be used no faster than they are to be renewed 2) Non-renewable resources should only be used within the rate of substitution by alternatives 3) Wastes should only be produced within the ability ti process them |
| Two-fold Purpose | 1) To maintain a level of production for current human consumption 2) To ensure that both the earth's resources and its stock are not depleted, and will be able to meet the needs of future generations |
| Sustainability Priorities | - Aim to sustain things that are health functioning ecosystems and their species - They provide us with support services like food and oxygen - We wouldn't live without them |
| Sustainability in Australia | -Not considered to be sustainable - Farming practices cause erosion, salinisation, and acidification - Means that food production is not sustainable - Farming, mining, logging, urbanisation, etc are destroying biodiversity |
| Geosphere | All the sediments that make up earth's land - the collective term for the earth's atmosphere, lithosphere, hydrosphere, and cryosphere. |
| Biosphere | Regions of the surface and atmosphere of earth occupied by living organisms |
| Ozone depletion | the thinning of the ozone layer present in the upper most atmosphere |
| Environment | The surroundings or conditions in which a person, animal, or plant, lives or operates. |
| Salinity | The dissolved salt content of a body of water |
| 4 S's of environmental services - SOURCES | Providing services - natural products that can be used by humans for our use e.g coal for fuel |
| 4 S's of environmental services - SINKS | Regulating services - processes in the natural environment that absorb our waste e.g bacteria in soil breaking down human waste |
| 4 S's of environmental services - SERVICES | Supporting services - Things done for us by the natural environment that don't produce consumable resources e.g Forests -> absorbing carbon dioxide and producing oxygen |
| 4 S's of environmental services - SPIRITUALITY | Cultural services - Refers to the personal relationships that humans have with the environment e.g Deep connections over generations such as Indigenous australians ^ could also be just swimming |
| Different views of our world - Human centered | Egocentric : - Humans are the most important creature - everything else is important only t support our lifestyle Anthropocentric: - Humans are the most imprtant species - Humans are in charge of earth - We only use nature to support our lifestyle |
| Different views of our world - Earth centered | Ecocentric: - We should minimise our impact and preserve earth - Humans are no more important than any other species Biocentric:- Humans have a responsibility to use resources sustainably - We have as much right to exist as other species |
| Environmental management | Process of taking steps and promoting behaviours that will have a positive impact on how environmental resources are used |
| Issues relating to the physical environment | - overuse of fossil fuels create extreme levels of air/water pollution - mismanagement of resources has depleted supplies ^ compromised the ability of future generations to meet their needs |
| Issues relating to the human environment | - consumerist nature of australia means we are no among the biggest waste producers - modern technology and declining birth rates = population ageing rapidly - migration to australia continue sto shape cultural characteristics of our society |
| Environmental goals - Ecological integrity | aka Natural Capital - refers to the health and well being of the physical environment - view notes |
| Environmental goals - Social justice and equity | The more socially just/equal a society is, the higher the levels of social capital - view notes |
| Ecosystem Equilibrium | A state in which all forces in an ecosystem are balanced. Over long periods of time, the ecosystem remains stable and reaches an equilibrium |
| Endangered Species (effects on an ecosystem) | - extinction of large number of species threaten survival rates of other living things like humans -^ Bc ecosystems can become unstable and collapse |
| Endangered species (main causes) | - loss of habitat - over hunting - competition with invasive species |
| Environmental challenges | - endangered species - global warming - ozone depletion - salinity - deforestation |
| Challenges to sustainability (biodiversity) | - Between 17000 to 100000 species annually reaching extinction |
| Biodiversity | refers to the variety of living organisms in the planet and is measured by the number of species present in a particular ecosystem |
| Challenges to sustainability (biodiversity) - IMPACTS | - impacts natural environment and us humans - Ecosystems services such as food, and crop pollination are in decline because the plants and animals that sustain them are dying out |
| Challenges to sustainability (biodiversity: 5 main causes of the loss of biodiversity | § Habitat change such as deforestation § Over exploitation of resources such as fresh water § Pollution of land, water, air § The spread of invasive species § Climate change, brought by human activity |
| Stakeholder | A person, group or organization that has interest or concern in an organization. |
