Ecological footprints measure the amount of productive land and sea area required to support a population's lifestyle or consumption patterns. Activities like energy production, transportation, urbanization, deforestation, agriculture all contribute to ecological footprints. Many countries and lifestyles currently have footprints that exceed their own biological capacity. To reduce footprints and promote sustainability, alternatives to fossil fuels like solar, wind, tidal and bioenergy can be pursued along with more efficient transportation and reduced pollution.

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

plant

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
