Rapid population growth
causes,effects and scientific solution
1.1. Rapid population growth
• is the increase in the number of individuals in a
population due to higher birth rates and decreased
mortality rates.
• One of these has been the ability to save lives
and create a better medical treatment for all.
• A direct result of this has been the increased
lifespan and the growth of the population.
.
.

• It can result from an increase in births (fertility rate), a
decline in the mortality rate, an increase in immigration, or
an unsustainable biome and depletion of resources.”.
• World population in 2023 is 7billion,in 2030
8.6 billion and in 2050 reaches 9.8billion.(UN
world population data)

1.1.2 Various Causes of Overpopulation
1. The 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.
• Talking about overpopulation shows that while there are
many factors that can increase the death rate for short
periods of time, the ones that increase the birth rate do so
over a long period of time.

2 Better Medical Facilities
• .Following this the industrial revolution started.
• .Technological advancement was perhaps the biggest
reason why the balance has been permanently
disturbed.
• .Science was able to produce better means of
producing food, which allowed families to feed more
mouths
• . Besides, medical science made many discoveries,
thanks to which they were able to defeat a whole
range of diseases.

3 . Child Labor
• .It is no less than a tragedy that child labor is still
in practice extensively in many parts of the world.
• . As per the UNICEF, approximately 150 million
children are currently working in countries having
few child labor laws.
• .The children being seen as a source of income by
impoverished families begin work too young and
also lose the educational opportunities reflected,
particularly when it comes to birth control.

4 . Technological Advancement in Fertility Treatment
• With the latest technological advancement and more
discoveries in medical science, it has become possible
for couples who are unable to conceive to undergo
fertility treatment methods and have their own babies.
• Today there are effective medicines that can increase
the chance of conception and lead to a rise in the birth
rate.
• Moreover, due to modern techniques, pregnancies
today are far safer.

5. Immigration
• Many people prefer to move to developed countries like the US,
UK, Canada, and Australia, where the best facilities are available in
terms of medical, education, security, and employment.
• The result is that those people settle over there, eventually
making those places overcrowded.
• If the number of people who are leaving the country is less than
the number of people who enter, it usually leads to more demand
for food, clothes, energy, and homes.
• This gives rise to a shortage of resources.
• Though the overall population remains the same, it just affects
the density of the population, making that place simply
overcrowded.

6 . Lack of Family Planning
• Most developing nations have a large number of
people who are illiterate, live below the poverty
line, and have little or no knowledge about family
planning. Besides, getting their children married
at an early age increases the chances of
producing more kids.
• Those people are unable to understand the
harmful effects of overpopulation, and lack of
quality education prompts them to avoid family
planning measures.

7. Poor Contraceptives Use
• Poor family planning on the part of partners can lead
to unexpected pregnancies though contraceptives are
easily available in developed countries.
• As per statistics, 76% of women aged between 16 and
49 in Great Britain used at least one form of
contraceptive, leaving a quarter open to unexpected
pregnancies.
• Whereas a study by the World Health Organization
(WHO) shows that this figure drops to 43% in
underdeveloped countries, which leads to higher birth
rates.

1.1.3 Effects of population growth
• 1. Depletion of Natural Resources
• The effects of overpopulation are quite severe of
natural resource depletion.
• The Earth can only produce a limited amount of
water and food, which is falling short of the
current needs.
• Most of the environmental damage is because of
the growing number of people on the planet.

2. Degradation of Environment
• With the over use of coal, oil, and natural gas, it has
started producing some serious effects on our
environment.
• Besides, the exponential rise in the number of
vehicles and industries has badly affected the quality
of air.
• The rise in the amount of CO2 emissions leads to
global warming.
• Melting of polar ice caps, changing climate patterns,
rise in sea levels are a few of the consequences that
we might have to face due to environmental
pollution.

3. Rise in Unemployment
• When a country becomes overpopulated, it gives rise
to unemployment as there are fewer jobs to support a
large number of people.
• The rise in unemployment gives rise to crime, such as
theft, as people want to feed their families and
provide them basic amenities of life.
• 4. High Cost of Living
• As the difference between demand and supply
continues to expand due to overpopulation, it raises
the prices of various essential commodities, including
food, shelter, and healthcare.
• This means that people have to pay more to survive
and feed their families.

5. Pandemics and Epidemics
• Poverty is linked to many environmental and social
reasons, including overcrowded and unhygienic living
conditions, malnutrition and inaccessible, inadequate,
or non-existent health care, for which the poor are
more likely to be exposed to infectious diseases.
• Further, high densities of population increase the
chance of the emergence of new pandemics and
epidemics.
• Famine is typically associated with less-developed
regions, and there is a high correlation with poverty
levels.

6. Malnutrition, Starvation and Famine.
• When the availability of resources is scarce,
starvation, malnutrition, along with ill health and
diseases caused by diet-deficiency such as
rickets become more likely.
• Famine is typically associated with less-
developed regions, and there is a high
correlation with poverty levels.

7. Water Shortage
• Roughly 1% of the world’s water is fresh and
accessible.
• Overpopulation is a major issue that creates
immense pressure on the world’s freshwater
supplies.
• As per the study, the human demand for freshwater
would stand at approximately 70% of freshwater
available on the planet by 2025.
• Therefore, people living in impoverished areas that
already have limited access to such water will be at
great risk.

8. Lower Life Expectancy:
 is the average number of years of lifeaperson
whohas attained agiven age can expect to live.
• Therefore, lower life expectancy caused by the
booms in population is experienced by less-
developed nations.
• This causes a shortage of resources in these
countries resulting in less access to medical care,
freshwater, food and jobs, and ultimately in a sharp
fall in life expectancy.

9. Faster Climate Change
• Overpopulation forces larger nations, like China and
India, to continue to develop their industrial capacities.
• They now rank as two of the three largest contributors
to emissions in the world, other than the United States.
• According to 97% of the scientific community, human
activities are changing global temperatures. If more is
not done to reduce individual carbon footprints on a
wide scale, larger populations may speed these
changes up.

• 1.1.4 Scientific solution of population growth
• 1. Better Education
• One of the first measures is to implement
policies reflecting social change.
• Educating the masses helps them understand
the need to have one or two children at the
most.

• Similarly, education plays a vital role in
understanding the latest technologies that are
making huge waves in the world of computing.
• Families that are facing a hard life and choose
to have four or five children should be
discouraged.
• Family planning and efficient birth control can
help in women making their own reproductive
choices

2. Education for Girl Child
• Currently, over 130 million young women and girls around the
globe are not enrolled in school.
• The majority of these live in male-dominated societies,
particularly in sub-Saharan Africa and South and West Asia,
that does not give women equal right to education as men.
• Entrenched(unfairly) gender norms and child marriage further
disrupt their access to education.
• The girl who receives less education is more likely to have
children early and vulnerable to exploitation.
• Moreover, impoverished families are less likely to enroll their
female children in school.

3. Making People Aware of Family Planning
• As the population of this world is growing at a rapid
pace(progress), raising awareness among people
regarding family planning and letting them know
about serious after-effects of overpopulation can
help to control population growth.
• One of the best ways is to let them know about
various contraceptive methods available to avoid any
unwanted pregnancy.

4 Social Marketing
• Social marketing has already been started by
some societies to educate the public on
overpopulation effects.
• The intervention can be made widespread at a
low cost.
• A variety of print materials (flyers, brochures,
fact sheets, stickers) can be distributed in places
such as at local places of worship, sporting
events, local food markets, schools and at car
parks.
