Exercise 2: Your
Ecological
Footprint
Before
doing this assignment, review the box at the top of page 16 in
Cunningham: “Measuring
sustainability and ecological footprints”
No matter how you feel about environmental issues and threats, the
simple
fact is that each of our lifestyles and consumption patterns does rely
on
natural resources and production systems that transform nature into
consumer
products, as well as create waste and pollution. One concept that has
evolved
to assess this impact is called the "ecological footprint": the
volume of land and resources appropriated to support a person, a
population, a
city, country, etc.
To get a feel for the way that individual and
collective
consumption affects land and resources, calculate your ecological
footprint. Go
to:
http://www.myfootprint.org/
and be sure to specify the units it uses to
express your footprint.
(1) If everyone on earth used the same amount of resources as you, how many earths would we need (given our current world population and level of technology)? (5%)
(2) What is your ecological
footprint: ________ (what units?) (5%)
(3) For the next part, you’ll have to play around with different answers to see how changes in certain categories affect the final footprint. Recalculate your footprint with changes in lifestyle and consumption to determine which three changes would bring about the largest reduction in footprint (e.g., fly less than 10 hours a year). You can see http://www.redefiningprogress.org/footprint/reducing.html for ideas (20%)
Describe each of the three changes and how much each changes the
final
footprint.
A.
B.
C.
(4) Reflect on these changes. Which
ones are easier and which ones are harder to make? Do
you have control over them as an
individual? Why or why not? Which require collective change and how
might these
be achieved? Write 1-2 well formed paragraphs answering these questions. (35%)
(5) Read through
the FAQ (frequently asked questions) about the
ecological footprint:
http://redefiningprogress.org/programs/sustainabilityindicators/ef/faq/
as well as the page
about methodology
http://redefiningprogress.org/programs/sustainabilityindicators/ef/methods/calculating.html
to answer the following questions in 1-2 sentences
each. (35%)
(a) Why does the footprint
calculator ask which country you live in?
(b) Why does it ask about climate,
and how does that affect the calculation of footprint?
(c) Why does the calculated
footprint decrease with additional number of people in the household?
(d) What five assumptions does the footprint calculator make? How reasonable do you think these assumptions are?
