Q

What is ecological economics? What do they try to do?

A

Discipline focused on sustainable development. Biodiversity valued. Conservative, preservative use of land. Like how the DNR enforces game and land laws.

Q

What is cost benefit analysis and why is it done? Why is it necessary to incorporate long-term gains? Why might leaders go into immediate reward rather than long-term?

A

-What produces the most monetary benefits while preserving the environment.
-It is good to look at the long-term impacts so we can see if there are going to be side effects
-So the leaders look good in the moment, or so they get more money.

Q

There has been interest developing in the East coast of the US for oil exploration-how might the precautionary principle be applied to this issue?

A

-The caution due to possibility of not having all the info available.
-i.e, there could be a species that could potentially be beneficial, like a bacteria that could help cure cancer, so we would suggest not drilling in order to preserve that

Q

**What is the opportunity cost of conservation programs?

A

-The loss of benefits to individuals or groups that would have been available from alternative courses of action. The opposite of what you could have done.
i.e. The possibility of ecotourism after logging and vice versa
-Resources cant be used by people
-Anything you couldn’t be able to do because of the money you spent on something else.

Q

What is the GPI and how does it differ from GDP? How has the calculation of these indices varied over the years? Why do they treat natural (or human caused) disaster differently?

A

-GPI: (Genuine Progress Indicator) Genuine impact of economy, good monetary increase. Doesnt always go up.
-GDP: (Gross Domestic Product) Market value, economic increase in country, only measures spending. Usually increases.
-People spend a lot during disasters (High GDP Low GPI)

Q

What is the EPI? What gives a country a higher score? How does economic stability relate to conservation efforts?

A

-Environmental Performance Index: Ranks countries based on how they protect the environment.
-Countries with higher per capita income generally rank higher on the EPI

Q

What is the fundamental difference between Direct and Indirect use value of a species?

A

-Direct: Consumptive/production values
-Indirect: Social, cultural, ethical, environmental value

Q

How is consumptive value different from a productive use value? How are each calculated/estimated? Examples?

A

-CV: Goods consumed locally, never made it to market, not bought or sold. i.e hunted game (replacement cost approach)
-PV: Value of resource harvested from the wild and sold in national and international markets. i.e raw sold materials (Price paid at first sale- cost incurred to bring it to that point)

Q

Why might it be important to provide a country with royalties or some other pay for the wild species collected in their territories and used to make new drugs, ag products, etc.?

A

Provides incentive for countries to conserve species
-Cyclosporin (medical mushroom, stole from countries, they sued)

Q

Why is ecosystem (primary) productivity important? How does the diversity of plants affect productivity or resistance to stress?

A

-It is the base of the food chain
-Carbon sequestration–produce O2 and absorb CO2 from atmosphere
-We depend on photosynthesis activity of plants and algae
-Plant productivity increases with diversity
-Increased diversity increases productivity, nutrient uptake from soil, insect diversity, tolerance of drought conditions and exotic species(fight invasives); decreased susceptibility to drought.

Q

How does terrestrial vegetation protect our surface waters? What can happen when its damaged?

A

-Helps fight erosion and runoff into bodies of water.
-Filter for surface water
-Erosion, landslides, water pollution, etc

Q

Why is sediment or silt a pollutant to aquatic organisms?

A

They can kill FW and marine organisms. They can also damage water supplies for humans

Q

Why should we be concerned with soil erosion

A

Could increase chances of flooding, water pollution and landslides

16
Q

How do trees help regulate climate? (local, regional, global)

A

-Local: Trees provide shade and important wind breaks
-Regional: Transpiration from plants returns water to the atmosphere, water returns as rain (lost vegetation =reduced rainfall)
-Global: Plants absorb CO2 for photosynthesis, may be important for reducing CO2 that contributes to global warming.

17
Q

How do natural communities contribute to waste treatment?

A

Marshes, swamps, mangroves, estuaries, and coastal shelf communities may process process toxic materials, pesticides, fertilizers, sewage, and other waste. Biological communities, mainly bacteria and fungi, may break down this waste

18
Q

Consider how wild species (that we don’t harvest) have value?

A

They could be pest control, seed distributors, pollinators, environmental monitors, indicator species, etc.
i.e bees that pollinate plants or birds that distribute seeds

19
Q

Larvae of mayflies are thought to occur in well oxygenated, relatively unpolluted, water. What might you call these organisms?

A

These species could be called indicator species. Another example is river otter in streams and rivers.

20
Q

What is ecotourism? Advantages and Disadvantages? How could it be a more “green” industry?

A

-When people pay to see exotic communities, rare species, etc.
-Advantages: Provides an economic argument to preserve diversity, may encourage habitat conservation or limited harvest of popular species, employment opportunities.
-Disadvantages: Damage to habitat, disturb animals, noise and light pollution, animal familiarity with humans.
-***

21
Q

Why is it dangerous for wild animals to become familiar and used to humans?

A

They would loose natural survival instincts. They could keep coming back, if anything bad happens the animal is most likely the one who gets killed.

22
Q

Why should you give yourself some recess time outdoors?

A

-Good for your health
-decreases risk of type 2 diabetes, cardiovascular disease, premature death, preterm birth, stress, and high blood pressure.
-Improves creative problem solving, ability to focus, memory by 20%, mood and self-esteem.

23
Q

What kind of scientific information do wild species provide us with?

A

-PCR (Polymerase Chain Reaction) developed using the DNA polymerase from bacterium thermus aquatus (endemic in natural springs)
-CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)
-Cas9: A nuclease that can cut SNA that matches an associated piece of RNA
