Causes of Overpopulation

Solutions to Overpopulation
Decline in the Death Rate:

At the root of overpopulation is the difference between
the overall birth rate and death rate in populations. If the number of children born each year equals the number of adults that die, then the population will stabilize.
Causes of Overpopulation
: Many people prefer to move to developed countries like US, UK, Canada and Australia where best facilities are available in terms of medical, education, security and employment. The end result is that those people settle over there and those places become overcrowded.
=> This gives rise to shortage of resources.
* It's making that place simply overcrowded.
5,993,945 of the Australian resident population were born outside Australia (in mid 2010 )
Causes of Overpopulation
Lack of Family Planning:
- Most developing nations have large number of people who are illiterate, live below the poverty line and have little or no knowledge about family planning.

- Getting their children married at an early age increase the chances of producing more kids.
Causes of Overpopulation
Better Medical Facilities:
After the industrial revolution, Technological advancement was perhaps the biggest reason.
- Science was able to produce better means of producing food, which allowed families to feed more mouths.
- Illnesses that had claimed thousands of lives till now were cured because of the invention of vaccines.
- No more people died
=> Became the starting point of overpopulation.
Depletion of Natural Resources
The Earth can only produce a limited amount of water and food.
They are cutting down forests, hunting wildlife in a reckless manner, and creating a host of problems.
Effects of Overpopulation
Degradation of Environment:
- With the overuse of coal, oil and natural gas, it has started producing some serious effects on our environment.
- Rise in the number of vehicles and industries have badly affected the quality of air.
-Rise in amount of CO2 emissions leads to global warming.
- Leading to the air pollution
Effects of Overpopulation
Conflicts and Wars
: Overpopulation in developing countries puts a major strain on the resources it should be utilizing for development. Conflicts over water are becoming a source of tension between countries, which could result in wars.
It causes more diseases to spread and makes them harder to control.
