Environmental Value Systems
What are the three Environmental Value Systems?
Ecocentric, Anthropocentric, Technocentric
what is positive and what is negative feedback?
positive - amplifies the change and keeps it going in the same direction (bad)
negative - promotes stability and returns changes back to a state of equilibrium (good)
Energy __ and matter __
flows , cycles
What is a system?
interrelated parts and the connection between them that unites them to form a complex whole, a bunch of smaller parts that work together for a whole
What is the name of Ms. Lyons' dog?
Bay
What is an EVS?
a worldview that shapes the way an individual or a group of people perceives and evaluates environmental issues. Often influenced by cultural, religious, economic, and politics
What are the pros and cons of using models
advantages = modeling allows complex ideas to be simplified , can be a basis for discussion
disadvantages = can be oversimplified , can be interpreted differently by different people
Distinguish transfers and transformations
transfers move energy or matter from one place to another without changing it and transformations move energy or matter but will change the state or form during the process
Name 5 factors that impact stability
-nutrient stores
-frequency and intensity of disturbances
-trophic complexity
-Biodiversity
How many sisters does Ariel from the little mermaid have?
6
Define each EVS
Ecocentric (nature centered) - minimum disturbances to nature
Anthropocentric (people centered) - people are managers of the Earth
Technocentric (technology centered) - technology solves problems
Give an example of a positive feedback loop
Give an example of negative feedback
ms. lyons judge if it is a valid answer
example : (neg) predator / prey relationship
example : (pos) white supremacy
Distinguish between open, closed, and isolated systems and give an example of each
isolated system = dont let anything in or out and nothing is transfered example: the universe
closed system = system that let energy in and out example : the Earth
open system = system that transfers in and out both matter and energy example a pond
what is resistance and what is resilience?
resistance : recover after a disturbance
resilience : continues to function during a disturbance
What is the largest ocean on Earth?
Pacific Ocean
Explain the parts and symbols of System Diagrams
Stores/storages = boxes or rectangles
Flows = arrows
Inputs = things going into a system (arrows)
Outputs = things going out of a system (arrows)
what are the 9 boundries?
- biodiversity - freshwater use
- climate change - land systems change
- novel entities - biochemical flows
- ocean acidification. - atmospheric aersol loading
- ozone depletion
what are the four transformations
energy --> energy
matter --> matter
energy --> matter (photosynthesis)
matter --> energy (burning wood)
What is an Environmental Impact Assessment and how do they work?
a baseline study that is done before a development project is undertaken, they assess the environmental, social, and economical impacts of the project, predicting and evaluating possible impacts and suggesting mitigation strategies for the project
Basically they provide decision makers with information in order to consider the environmental impacts of a project
what are the names of the three main minions in the minion movie
kevin, stuart, and bob
To what extent do all EVS's care about what happens to the environment?
Ms. Lyons judge if that is in depth enough
distinguish between ecosystem goods and services with reference to a named ecosystem
ms lyons judge if that is a valid answer
What are the 1st and 2nd law of thermodynamics and why are they important for an ecosystem
1st law : energy is neither created or destroyed
2nd law : as energy changes form while flowing through a system, entropy (disorder) increases (energy degrades as it goes through a system)
Thermodynamics are important for ecosystems, as photosynthesis can only happen in the presence of sunlight, not in the presence of chemical energy or heat
define natural capital, natural income, and sustainable natural income
natural capital : natural resources that produce sustainable natural income of goods and services
natural income : the yield from the natural income
sustainable natural income : the yield from natural capital that can be taken without reducing the capital
What is the scariest animal according to dwight shrute?
box jellyfish
