Ecosystem
-An area in which biotic and abiotic interactions and relationships
-Every action has a reaction
Sustainability
Balance within an ecosystem between action and reaction
Feedback loops
Measurement of action causing a reaction
positive feedback loop
feedback loop that causes a system to change further in the same direction
negative feedback loop
A feedback loop that causes a system to change in the opposite direction from
which it is moving
Sustainable development
Understanding and appreciation for future impacts within dev/
Instrumental value
The value which is based on the given role within the ecosystem
intrinsic value
Measure or value which is based on the aesthetic of within a system
What is environmental science?
A study between conditions or organisms and how those two groups maintain
that balance or equilibrium
4 Global Issues
, -atmospheric changes
-human population
-loss of biodiversity
-loss of viable soil
acid deposition
Sulfur oxides and nitrogen oxides, emitted by burning fossil fuels, enter the
atmosphere-where they combine with oxygen and water to form sulfuric acid
and nitric acid-and return to Earth's surface
combine with water
Acids become acids once they _____
NOx
nitrogen oxides and refined gasses
SOx
sulfur oxides, lower refined diesel & coal
HNO3
nitric acid comes from NOx
H2SO4
comes from SOx
Systemic acidic compounds of plants
-occur on a cellular level
-Cell pushes hydrogen ions out
Acid rain hits plants and is brought up from the soil...
-Doesn't break up the plant because there isn't enough hydrogen but it makes the
plant weaker (the plant changes color, wilts, shrinks up, and ultimately ends up
dying)
-The plant is trying not to absorb the hydrogen ions
Acid leaching definintion
