Title: Ecological Footprint


1
Ecological Footprint
2
What is Ecological Footprint?
  • A way of measuring the demand humans put on the
    environment
  • The amount of space needed to support a persons
    activities
  • Can be used to measure one person or the
    population of a city, country or the world

3
How is the EF measured?
  • A table is used based on the amount of
    productive land needed to support human
    activities
  • Types of land include
  • Crop land (fruits, veggies)
  • Forested land (trees)
  • Pasture land (animals)
  • Energy land (energy source)
  • Degraded land (used to be productive)

4
Measuring EF
  • For example
  • For dinner you have a steak, baked potato (with
    butter and sour cream) and vegetables.
  • Therefore, you are using
  • crop land (for the vegetables and potato)
  • Pasture land (cow-for the steak and cow for the
    butter and sour cream)
  • Energy to cook the meal
  • Land is not just local-as we rely on products
    from all around the world
  • Remember, ALL human activities impact the land
    and leave an Ecological Footprint

5
What does this mean to Canadians?
  • The average Canadians EF is 4.27 ha/person
  • Canada is only part of the world-so we must
    consider the rest of the world
  • Worlds EF is 1.8ha/person
  • If all people lived like Canadians we would need
    2 additional earths
  • Fair Earthshare-equal amount of earth for the
    world population1.44ha/person

6
Sustainability
  • Sustainable development is development that
    meets the needs of the present without
    compromising the ability of future generations to
    meet their own needs.
  • World Commission on Environment and Development

7
Sustainability
  • If we continue to populate, consume products at
    our current rate and expect our economy to grow
    every year without replenishing we will
    experience Hardins Tragedy of the Commons
  • (Cartright, On the Threshold)
  • Evidence
  • Fish stocks (i.e. East Coast Fisheries)
  • Aquifers emptying (depleting at rate 20 times
    faster than replenishment)
  • Forests being cut down (1/4 of forests cut in
    last 40 years)

8
Steps to Sustainability
  • Shift values from excessive material consumption
  • Use technology to change industrial processes to
    reduce pollution
  • Use education and media to increase ecological
    awareness
  • Tax incentives for conservation and eco-friendly
    products
  • Develop laws holding business accountable
  • Improve efficiency and accessibility of public
    transportation
