3. INTRODUCTION
WE ALL DEPEND ON NATURE
• Through activities such
Drinking
Eating
Breathing
we exchange energy as well as matter
with the environment
 Basically we use
• Energy for heat and mobility
• Wood and timber for housing and
paper
• Food and water for living organism

4. INTRODUCTION
WE ALL DEPEND ON NATURE
 NATURE
• Absorbs our waste
• Climate stability
• Protect us from ultraviolet
radiation
• Sources of our lives as well
as our well being

5. ECOLOGICAL FOOTPRINTS
• According Venetoulis & Talberth
(2008), an ecological footprint is a
measure of the amount of productive
land required to support the lifestyle of
an
- Individual, a city, region or
Country.
• Production and service deliveries
make use of land, therefore have some
amount footprint.

6. ECOLOGICAL
FOOTPRINT
• Energy land
- Most energy production requires
burning of fossil fuels such as
coal, natural gas, oil etc. that
produces carbon dioxide (CO2)
- This Carbon dioxide requires
carbon sinks to effectively
absorb excess carbon dioxide
produced.

7. ECOLOGICAL FOOTPRINT
• Other activities of human that may have effects on the
natural environment comprise.
 Urbanization
 Deforestation
 Agriculture
 Transportation
 Nations also leave their imprint in the ecological set up.

10. National Footprint
 Many countries in the world today, are running
ecological deficits, with Footprints larger than their own
biological capacity (National footprint network,2016).
 In U.S for example, each person uses 4.5
hectare/person.
 The average for world-wide is 1.5hectare/person.
 If everyone were to adopt the lifestyle of U.S, we would
need 3 planets.

12. WHAT CAN WE DO?
SUSTAINABILITY
 Sustainability may be defined as maintaining well-being over a long, perhaps
even an indefinite period (Kuhlman & Farrington, 2010)
 Footprint assumptions
 It is important for humanity to live within the earth carrying
capacity
 A Change in our lifestyle to reduce effects pollution on
ecosystem.

13. WHAT CAN WE
DO?
• We should resort to other sources of
energy other fossil fuels.
• Moving towards solar energy would
reduce our footprint

14. WHAT CAN WE
DO?
• Using wind energy will be ideal for
reducing our footprint on the
ecology.
• Tidal energy will also be an ideal
for footprint reduction.
• The use biofuels instead of ancient
fossil fuel.
• Building very fast transportation
system
• The use of Catalytic converter to
reduce the production of harmful
gases. www.public.iastate.edu/~cfford/EcologicalFo
