this presentation is aimed to describe either population growth is a major factor in environmental change or somethings else is underlying in this phenomenon?

1. Is Population Growth: A Key Factor
in Climate Change?

2. Outline
 Population growth
 Causes
 Growth Rate at Global level
 Impacts
 Controversy
 Recommendations
 conclusion

Population Growth
Green House Effect

Climate Change

4. Population growth
An increase in the number of people that reside in
a country, state, county, or city. To determine
whether there has been population growth, the
following formula is used: (birth rate +
immigration) - (death rate + emigration).

5. Causes
Illiteracy and ignorance
 Radical beliefs regarding birth control.
 Desire of male child
Unawareness about the basic birth control
measures.
 Ineffectiveness of family planning
Advancement in technological innovations
eradicating many fatal illnesses.

6. Growth Rate at Global level
 World population 6.5 billion (2006)
 Today 7.203 billion (UNCB)
 Projected population 20 billion in 2055
 Death rate 6.9/1000

7. Impacts
 Urbanization
 Deforestation
 Increased use of earth resources (fossil fuels)

8. A Controversy
 Either population growth has devasting effect on
envirinment or lifestyle of people
?

9. Living style of people is problem in reality
 the world’s wealthiest 20% (i.e. the rich countries)
consume approximately 80% of the world’s resources,
while the rest of humanity shares the other 20% of resource
consumed
 In terms of historical emissions, industrialized countries
account for roughly 80% of the carbon dioxide buildup in
the atmosphere to date.
 Annually, more than 60 percent of global industrial carbon
dioxide emissions originate in industrialized countries,
where only about 20 percent of the world’s population
resides.

10. Ironic situation

11. In Developing Countries In developed countries
Comparison

12. Recommendations
 Need to educate people, specially women education
 Need to stop Urbanization by decentralizing
resources and life facilities in rural areas
 Need to used earth or environmental friendly
technologies and way of development
 More tree plantation

13. Conclusion
 The economic, political and technology choices have
a more important bearing on climate change than
“over population.”
