Module 1: Finals Version Flashcards
characteristics of sustainability (3)
- it is defined by the problems that it addresses rather than by the approaches employed
- focuses on coupled human-environment systems, making it strongly interdisciplinary
- rooted in values and solutions differ depending on the values of different people
sustainability science (2)
- examines the impacts of human activities on the environment
- attempts to identify how human needs can be met without compromising the global ecosystems which we all depend on
what is driving the increase in human impact on our environment (2)
- major factor is human population growth
- patterns of consumption (excessive consumption by richer countries)
what fields are important in addressing the increase in human impact on our environment (3)
- academic
- political
- ethical
earth system science (3)
- focus on studying processes at the global scale with connection to human society
- embraces multiple disciplines in transcending disciplinary boundaries to treat Earth as an integrated system
- seeks deeper understanding of physical, chemical, biological, and human interactions that determine the past, present, and future states of earth
what can the rise in human population be linked to
- fossil fuels, Industrial Revolution, mechanization of agriculture that allowed additional billions to be fed
system
- collection of interdependent parts enclosed within a defined boundary
what is the Earth system comprised of
- sub-systems
what are the sub-systems of the Earth
- atmosphere
- biosphere
- hydrosphere
- lithosphere
- anthroposphere
anthroposphere
- sub-system of Earth that considers human impacts on environment
lithosphere (4)
- the cold, hard, solid rock of the planet’s crust (surface)
- the hot semi-solid rock that lies underneath the crust
- the hot liquid rock near the centre of the plant
- the solid iron core of the planet
hydrosphere
- all of the planet’s solid, liquid and gaseous water
biosphere
- all of the planet’s living organisms
atmosphere
- all of the planet’s air
what is Earth system science’s focus (3)
- interactions between ocean, atmosphere, living things, geological processes, land surface dynamics, and human systems
- processes that connect biological, physical, and human systems operating near the Earth’s surface
- how interrelationships between physical and biological systems impact each other and lead to changes
what are the main characteristics of earth systems science (ESS) (5)
- builds upon and bridges the scientific disciplines
- holistic model of earth
- contextual approach
- exploration and discovery of causes and effects at a global level
- identification of critical thresholds
cryosphere
- ice/snow
heliosphere
space surrounding earth, created by the sun
sustainability (2)
- the process of living within the limits of available physical, natural, and social resources in ways that allow the living systems in which humans are embedded to thrive in perpetuity
- human-centric topic
sustainable development (2)
- development that meets the needs of the present without compromising the ability of future generations to meet their needs
- this development will leads us to achieve sustainability
what are the 3 dimensions of sustainability
- social
- economic
- environment
social dimension of sustainability
- refers to values that promote equality and respect for individual rights
economic dimension of sustainability (2)
- refers to economic development and growth while encouraging and promoting protection of the environment by limiting risks posed by production
- recycling and use of renewable energy are fundamental
environmental dimension of sustainability
- commitment to protect the environment by reducing risks and measuring impacts
