What is an ecological footprint?
From: www.globallivingproject.org/footprint.html
The
morning alarm rings. You take a hot shower, brew up a cup of coffee,
read a bit from the morning newspaper and hop in the car to get
to work on time. Have you ever stopped to consider the total environmental
impact involved in each of these daily habits? The ecological footprint
is one technique to answer the question of how our lifestyle effects
the planet.
The ecological footprint was developed at the University of British
Columbia department of Community and Regional Planning by Dr. William
Rees and Dr. MathisWackernagel. It estimates how much of Earth's
productive land and sea is used to produce the food, materials and
energy that we consume and to assimilate our wastes. The ecological
footprint looks behind the scenes to really see what it takes to
make an alarm clock, a cup of coffee, our clothes, our home and
to operate our automobile. This gets complicated, especially in
our global economy where the products we consume originate from
all over the world.
As an example lets take a deeper look at that morning cup of coffee.
Land is needed to grow the coffee beans, for the processing and
distributing operations, to house corporate management and advertisers
as well as the downtown store. Additional forest land is needed
to absorb the CO2 resulting from all the energy burned harvesting,
processing and shipping the coffee. Somewhere on the planet land
was mined to make the metal for the machinery used in each step
of the process and for the chemicals used in fertilizers and pesticides.
Given that 6 billion humans are sharing all the biologically productive
land on this earth, each person has 5.5 acres as their personal
planetoid. You can think of this 5.5 acres as your virtual homestead,
spread around the world to grow your food, produce all your material
needs, including energy, and to absorb all your wastes. As population
doubles over the next 30 years, we will each be left with a 2.75
acre personal planetoid. Leaving sufficient habitat for the 25 million
other species on Earth brings this area down to one wise acre now
and half an acre in 30 years.
How much Earth is there?
- 126 billion acres
- Amount of Earth covered by low bio-productive oceans, deserts,
ice caps, and human settlement: 94 billion acres
- How much bio-productive land and sea exists? 32 billion acres
- Current human population: 6 billion
- How much exists per person today? 5.3 acres
- How much is available per person if we leave 80% wild for the
25 million other species on Earth? 1 acre
- How much do humans on average use globally ? 6.9 acres
Currently, Earth is ecologically filled with humans and as
one specie we overshoot Earth's bio-capacity by 30%!
It is only since the industrial revolution that resource use and
consumption has skyrocketed. The US was built on foundations of
frugality, yet today, North Americans are the world's greatest consumers.
If the world's people consumed as North Americans, we would need
four Earths! The link between consumer habits and global warming,
war, species extinction, and social injustice is lost amidst fast
paced advertising and a throw-away consciousness.
Before we can tell those in the so called "third world" to reduce
their population, we could gain respect and credibility if we first
got our own house in order and reduced our consumption. Simple mathematics
reveals that consuming four times the amount available per capita
(as is typical for industrialized nations) means that for each over-consumer
there needs to be three other people using one third of what is
available to them. Imagine the planet to be a pizza and you have
4 friends at the table. The pie is divided into quarters. If one
wants four times average (3/4 of the pizza), the other 3 need to
divvy up one quarter. With this understanding, it makes ethical
sense to only use our share.
Ecological Footprints Around The World
- United States - 24 acres
- Canada - 18 acres
- Switzerland - 12 acres
- Russian Federation - 11 acres
- World Average - 6.9 acres
- Mexico - 6.4 acres
- Personal Planetoid - 5.3 acres
- Turkey - 5 acres
- China - 4 acres
- GLP - 3.2 acres (summer) and 4 acres (winter)
- India - 1.9 acres
- Bangladesh - 1 acre
- Personal Planetoid (80 percent wild) - 1 acre
The reality is that Earth is ecologically filled, meaning that
everything we use beyond one acre is detracting from what another
person or species has to nourish their lifestyle. Looking at the
implications of such inequity is the heart of the GLP.
The power of ecological footprinting is that it helps us step
out of the context of a wealthy, industrialized, human centered
culture. We can use it to design a lifestyle, a business, or an
institution that is in alignment with our personal or collective
value system. The beauty of footprinting is that if 100 people designed
a lifestyle that was within their personal planetoid, we would see
100 unique solutions. Footprinting inspires us to play with our
creativity and calls on us to find ways of sharing Earth with other
humans and other species. The GLP is committed to developing practical
and philosophical tools that promote sustainable lifestyles applicable
to both rural dwellers and urbanites alike. What's your ecological
