The biological science that studies how organisms interact with one another and with their environment
A set of organisms within a defined area that interact with one another and with their environment
Reliance on Solar Energy
The sun provides enerygy for photosynthesis, which provides energy for plants,which provide energy for non-plants
Large variety of organisms allows life to survive almost any condition. Also provides renewal of topsoil, pest control, air and water purification, etc.
Circulation of chemicals from environment into organisms and back to environment. Allows same materials to be used over and over
Materials and energy in nature that are essential, or useful to humans, classified as renewable and non renewable
The highest rate at which we can use a renewable resource indefinitely without reducing its supply
Natural Capita Degradation
Environmental degredation (e.g. destroying ecosystems, decrease in biodiversity)
Any presence in the environment of any agent at a level harmful to the health, survival, or activites of organisms
Output Pollution Control
Cleaning up or dilluting pollutants after they have been released into the environment
The amount of biologically productive land and water needed to provide the people in a particular area with an indefinite supply of renewable resources
Population x Affluence x Technology
Estimate of how much humanity is degrading the natural capital it depends on
Ecological Tipping Point
An often irreversable Shift in the behavior of a natural system (i.e. collapse in fish populations, premature extinctions, and long term climate change)
Change in human behavior hoped to come within this century, would involve reducing ecological footprint to live more sustainably
Humans learned how to grow and breed plants and animals for food, clothing, etc.
People unable to fulfill needs for food, water, shelter, health, and education, leads to environmental degredation, pollution leads to poverty, lack of hygene, premature deaths
We should manage the Earth for our benefit, but we still have ethical responsibility
Planetary Management World View
We are seperate from and in charge of nature, only exists to meet our needs and wants
Environmental Wisdom Worldview
We are a part of and dependent on nature, nature exists for all species, not just us
Four Basic Causes of Environmental Problems
1) Population growth
2) Wasteful and unsustainable resource use
4) Failure to include the harmful environmental costs and service goon on resource prices
Environmentally Sustainable Society
Meets current and future basic resource needs of its people in a just and equitable manner, without compromising the resource needs of future generations
Renewable Resources such as plants, animals, and soil provided by the earth's natural capital, not depleting or degrading the natural capital, and providing humans with adequate access to it for the forseeable future.
Getting people with different views and values to talk and listen to one another to solve environmental problems, trade off solutions
Scientific Law (law of nature)
A well tested and widely accepted description of what we find happening repeatedly in nature
Tentative (frontier) Science
Has not been widely tested or accepted yet so it id not considered reliable
How useful a form of matter is to humans as a resource based on availability and concentration
Second Law of Thermodynamics
Whenever energy is converted from one form to another, there is a loss of usable matter (lowers quality)
Positive feedback loop
Causes a system to move furhter faster in a certain direction (e.g. ice caps)
Negative Feedback Loop
(Corrective) Causes a system to start moving the opposite direction (e.g. thermostat)
Lack of response during a period of time between the input of a feedback stimulus and a response
