Quiz #8

Question 1

What are the 3 ecological footprint future scenarios? Describe 1 of them

Answer 1

• Nothing changes, business as usual, humans will continue to have a large ecological footprint, more than the earth can support
• Slow changes, moderate changes with a small buffer at the end of the goal. Humans lessen ecological footprint, but at a moderate rate
• Rapid changes, the highest change with the largest bufer at the end of the goal. The most reduction in human ecological footprint with the largest ecological buffer

Question 2

What are ecosystem services? Give an example.

Answer 2

Ecosystem services are benefits that ecosystems provide to humans that are hard to put an monitary value on and usually cannot be sold.
An example is air quality. It has a direct benefit and use to humans but it is hard to put a dollar figure on it

Question 3

What does the ecological footprint measure?

Answer 3

measruement of how human populations demand on nature

is derived by tracking how much biologically productive area it takes to provide for all the competing demands of people

Question 4

Define biocapacity

Answer 4

Biocapacity is the amount of biologically productive land and sea area available to provide the resources a population consumes and to absorb its wastes, given current technology and management practices

Question 5

When did the global overshoot begin?

Answer 5

1970

Question 6

Describe what an ecosystem process is and give an example

Answer 6

..are the physical, chemical, and biological processes that link organisms and their environment

four fundamental ecological processes are:
•the water cycle:•Does rain feed plants and recharge groundwater, or does it run off the land, causing erosion? Do springs and streams flow seasonally or year-round?
•the mineral cycle:•Are nutrients available to living things? Or are they locked in standing dead growth, or sunk below the root zone? Do they escape when plants burn or soil washes away?
•solar energy flow:•How much sunlight falls on green leaves and gets turned into food for the ecosystem? How much is wasted striking dead growth or bare ground?
•community dynamics (succession)•Do many species have fairly stable populations o

Question 8

List and explain at least 2 criteria that the highest quality projects must have to be considered a carbon offset?

Answer 8

Question 9

For what reason did interest and concern about the environment increase in the 20th century?

Answer 9
