1.1 Environmental Value Systems
What is an EVS?
An environmental value system
A ___ ____exchanges both energy and matter across its boundary while a closed system only exchanges energy across its boundary
Open System
-------- is defined as the useful energy, the work or output produced by a process divided by the amount of energy consumed being the input to the process.
What is efficiency?
__ is the use and management of resources that allows full natural replacement of the resources exploited and full recovery of the ecosystems affected by their extraction and use
What is sustainability?
A system may best be defined as __
What is an assemblage of functioning parts without inputs or outputs?
A value system that influences the way that we view the world.
(Any aspect of culture)
Language
Religion
Tradition
A ___ ____ is a hypothetical concept in which either energy nor matter is exchanged across the boundary
Isolated System
----- is a measure of the amount of disorder in a system
What is Entropy?
___ Is the natural yield obtained from natural resources
What is natural income?
Name an input to a closed system.
What is heat energy?
What is a technocentric view point?
A technocentric view point argues that technological developments can provide solutions to environmental problems.
Systems can we thought of as one of three types. The three being -- --- --
Open, Closed, & Isolated
------- of thermodynamics is the principle of conservation of energy, which states that energy is an isolated system can be transformed but cannot be created or destroyed.
what is the first law of thermodynamics
What are EIA's?
What is Environmental Impact Assessments?
What is an ecocentric view point?
An ecocentric view point integrates social, spiritual, and environmental dimensions into a holistic ideal. It puts ecology and nature as central to humanity and emphasizes a less materialistic approach.
--- occur when energy or matter flows and changes location but does not change its state
Transfers
-------- refers to the fact that energy is transformed through energy transfers. Entropy is a measure of the amount of disorder in a system. An increase in entropy arising from energy transformations reduces the energy available to do work.
What is the second law of thermodynamics?
An ___ model is used to estimate the demands that human populations place of the environment
What is an ecological footprint?
Name a major source of pollutants
What is:
Combustion of Fossil Fuels
Domestic Waste
Industrial Waste
Agricultural Waste
What is the world’s worst industrial disaster?
Bhopal Disaster (India)
A ___ ____exchanges both energy and matter across its boundary while a closed system only exchanges energy across its boundary
Open system
___ is reached when an ecosystem experiences a shift to a new state in which there are significant changes to its biodiversity and the services it provides.
What is an ecological tipping point in ecological reference?
When changing what we do seems too difficult
What is Inertia?
Describe pollution.
What is an activity, at a rate greater than that at which it can be rendered harmless by the environment, and which has an appreciable effect on the organisms within it.
