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