Paper -1 Flashcards
What does the Environmental value system do?
shapes the way individuals see
environmental issues.
Ecocentrism
Minimum disturbance of natural processes.
Anthropocentrism
People as environmental managers of sustainable global systems.
Technocentrism
Technology can keep pace with and provide solutions to environmental problems.
Society
Society is defined as an arbitrary group of individuals who share some common characteristics such as location, cultural background, religion on value system.
For what is used the System approach
visualising a complex set of
interactions in a system.
System
A system is defined as an assemblage of parts and the relationships between them that enable them to work together to form a functioning whole.
Biomes
Biomes are groups of
ecosystems with similar climates
Systems may be…
Living, non-living, large, or small
Storages

Scale of a system
The scale of a system can range from a small part of a larger ecosystem, such as a tree in a forest, to, on a larger scale, the whole ecosystem.
Whatever their size, all these systems have
inputs, stores and outputs.
Emergent properties
features of a system that cannot
be present in the individual
component parts.
Reductionist approach
to a system reduces the complex interactions within it to their constituent parts, in order to study them;
Open system
An open system exchanges
both matter and energy within
its surroundings across the
boundaries of the system.
A closed system
A closed system exchanges
energy but not matter across
the boundaries of the system.
isolated system
An isolated system exchanges
neither energy nor matter with
its environment.
