World Population Day is observed annually on July 11th to raise awareness of global population issues. The world population is currently estimated at 7 billion people according to the UN. Overpopulation can cause issues like increased poverty, pollution, and depletion of resources. Pakistan has a high population growth rate due to factors such as lack of education and family planning programs. Methods to control population include contraception, reducing infant mortality, and in China's case, a controversial one-child policy. Controlling population is important for sustainable development.

10. What is overpopulation?

point of overcrowding, depletion of natural
resources, or environmental deterioration.
It is a major problem of developing third

world countries.
Pakistan has 2.54 percent of the world´s
total population which means that one
person in every 39 people on the planet
is a resident of Pakistan ..

11. Causes of over population in
Pakistan
 Lack of education
 High birth rate
 Desire for male child
 Early marriages

12. POPULATION CONTROL
 Human population control is the practice of
artificially altering the rate of growth of a
human population. Historically, human
population control has been implemented by
limiting the population's birth rate, usually by
government mandate, and has been
undertaken as a response to factors including
high or increasing levels
of poverty, environmental concerns, religious
reasons, and overpopulation.

14. Methods of population control
 contraception
 abstinence
 reducing infant mortality so that parents do
not increase their family size to ensure at
least some survive to adulthood.
 abortion
 infanticide
 emigration
 decreasing immigration
 sterilization

15. ONE CHILD POLICY IN
CHINA
 The most significant modern population control
system is China's one-child policy, in which, with
various exceptions, having more than one child is
discouraged. Unauthorized births are punished by
fines, although there have also been allegations of
illegal forced abortions and forced sterilization.
 The Chinese government introduced the policy in
1978 to alleviate the social and environmental
problems of China. According to government officials,
the policy has helped prevent 400 million births.

16. Reasons for its failure
 In 2010, it was announced that the majority of the citizens
initially subject to the policy are no longer of
reproductive age and it has been speculated that many
citizens simply disregard or violate the policy in more recent
years. The deputy director of the Commission stated that the
policy would remain unaltered until at least 2015.
 In March 2011, the Chinese government reviewed the policy
and expressed considerations to allow for couples to have a
second child.
 he US State Department, the Parliament of the United
Kingdom,and the human rights organization Amnesty
International have all declared that China's family planning
programs contribute to infanticide.

18. Effects of overpopulation
 Poverty
 Inflation
 Lack of employment Opportunity
 Rising levels of atmospheric carbon dioxide
 Global warming
 Pollution
 increased demand for resources such as
fresh water and food
 starvation and malnutrition
 consumption of natural resources faster than
the rate of regeneration (such as fossil fuel)

19. CONCLUSION
 Hence, it is concluded that over population is
a threat for the stability and strengthening of
any nation.
 So steps should be taken to aware the
people that if the families will be small than
they can enjoy their lives with all the
facilities and the next coming generation will
be healthy and organized due to the proper
attention of parents.
 Education should be promoted in small
villages and towns.
 Importance and advantages of small family
should be promoted in the newly married
couples and the girls who are about to get
married, because women health is also
affected with more children.

20.  So for a healthy family, healthy
mother and progressive society,
population control is the most
important aspect.
