Question 6

Question 1

What is an ecological footprint?

Answer 1

Productive land and water area an [individual, a city, a country, a region, or humanity] uses to produce the resources it consumes and to absorb the waste it generates

Question 2

What is GHA?

Answer 2

The unit for ecological footprint, Global hectares

Question 3

What is bio capacity?

Answer 3

Amount of land and sea available on earth to provide the resources to meet demand

Question 4

What do the variables in EF = D/Y stand for?

Answer 4

EF = Ecological footprint
D = annual demand of a product
Y = annual yield of the same product

Question 5

What do the variables in EF = (P/YN)YFEQF stand for?

Answer 5

EF = Ecological footprint
P = the amount of a product harvested or waste emitted (equal to D above)
YN= the national average yield for P
YF = yield factor
EQF = equivalence factor

Question 6

what is a Carbon footprint?

Answer 6

the amount of carbon (usually expressed in equivalent tonnes of CO2) being emitted by an activity or organization

Question 7

What are Fossil Fuels?

Answer 7

Oil and natural gas are formed from the remains of prehistoric plants and organism

Question 8

What is Carbon intensity?

Answer 8

the measure of greenhouse gas (GHG) emissions associated with producing and consuming a transportation fuel, measured in grams of carbon dioxide equivalent per megajoule of energy (gCO2e/MJ or gC/MJ)

Question 9

what is gC?

Answer 9

grams carbon

Question 10

what do the variables in I=PAT stand for?

Answer 10

Environmental Impact = Population X Affluence X Technology

Question 11

What do the variables in C=Coexp(rt)

Answer 11

C= carbon emission rate after tyrs(GtC/yr)
Co= initial emission rate (GtC/yr)
r= overall exponential rate of growth (yr-1)
