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 worldโs wealthiest 20% (i.e. the rich countries)
consume approximately 80% of the worldโs 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 worldโs 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
โover population.โ
