Overpopulation

The six factors

Fertility rates

The death rate

a person can reproduce

The presence or absence of parental figures

The number of children per family

It's better to have two child because there would be less economic burdens

The initial age of population (Whether the population was old or young at the start)

If the population has a bigger demographic in one age group then that age group will effect the population

Migration

Immigration

Unchecked immigration into countries may lead to overpopulation to the point where those countries no longer have the required resources for their population. This is particularly problematic in countries where immigration numbers far exceed emigration numbers.

Falling Mortality Rates

the Industrial Revolution brought with it a revolution in the world of medicine. Scientific progress allowed us, from then onward, to overcome diseases that previously could only end in death. The invention of vaccines and discovery of antibiotics such as penicillin saved thousands of lives and were a key factor in unfettered population growth. As the number of annual deaths fell, while births remained constant, so the population increased.

Lack of female education

Better Healthcare facilities

Poverty

A lack of educational resources, coupled with high death rates leading to higher birth rates, result in impoverished areas seeing large booms in population. The effect is so extensive that the UN has predicted that the forty-eight poorest countries in the world are also likely to be the biggest contributors to population growth.

Child Labor

This can result in children being seen as a source of income by impoverished families. Furthermore, children who begin work too young also lose the educational opportunities they should be granted, particularly when it comes to birth control.

An increase demand for food, water, housing, healthcare, transportation and more

Ecological Degrade

An increase in population means more deforestation, increase in pollution, and more

Less Fresh Water

While there is plenty of water on the planet, it is very much a scarce resource. Only 2.5 percent of water resources are fresh water, and just a small fraction of that is available as unpolluted drinking water.

Farming

As the global population increases, more food is needed. Such measures may be met through more intensive farming, or through deforestation to create new farm lands, which in turn can have negative outcomes.

intensive farming is also considered a major contributor to climate change due to the machinery required. This effect will likely intensify if the population continues to grow at its current rate.

Eutrophication

Eutrophication causes the dense growth of plant life that consumes oxygen, resulting in the death of aquatic animals. Other major sources of eutrophication are industry and sewage disposal--both related to population growth.

Agricultural runoff is one of the main causes of eutrophication, the presence of excessive nutrients in bodies of waster, such as large pockets like the Dead Zone of the Gulf of Mexico. Worldwide, there are more than 400 marine 'dead zones' caused by eutrophication, collectively covering an area six times the size of Switzerland.

While there is plenty of water on the planet, it is very much a scarce resource. Only 2.5 percent of water resources are fresh water, and just a small fraction of that is available as unpolluted drinking water.

Degrade in Biodiversity

The effect of overpopulation on the world’s wildlife is also a major issue. As demand for land grows, so too does the destruction of natural habitats, such as forests. Some scientists warn that if present trends continue, as many as 50% of the world’s wildlife species will be at risk of extinction.

Increase in conflict

environmental disruption and overpopulation has the potential to trigger an increase in violence and political unrest. There are already wars being fought over for resources in the Middle East

Higher Risks of Pandemics

Many diseases have been causing issues for people, COVID-19 is one of these examples. These diseases are created in animals and passed onto people. Humans have begun to interact with animals more than normal because of overpopulation.

Less Freedom and More Restrictions

As population densities increase, laws, which serve as a primary social mediator of relations between people, will more frequently regulate interactions between humans and develop a need for more rules and restrictions to regulate these interactions.

Elevated Crime Rates

As human overpopulation drives resources and basic necessities, such as food and water, to become scarcer, there will be increased competitiveness for these resources which leads to elevated crime rates due to drug cartels and theft by people in order to survive.

Rising unemployment

a high number of workers exist for a limited number of vacancies and this seems destined to lead to high rates of joblessness in the future.

Rising Living Costs

increasing living costs in most countries. Fewer resources, less water, the packing of many people into confined spaces and a lack of money are provoking an increase in the cost of living whereby only a percentage of the population will be able to cover all their needs.

Technological Advances

high concentrations of people in urban areas also brings with it research and development in the quest for solutions to the population’s needs. An example is the popularisation of communication technologies and the generation, collection and use of Big Data for sustainable ends, as well as the emergence of Smart Cities adapted to ensure good living conditions for the increasing population.

Better Sex Education

A lack of sex education – or poorly-implemented education – has led to overpopulation issues in many countries. The issue is so pronounced that the United Nations Population Fund (UNFPA) is calling for improvements to be made, particularly in poorer areas of the world.

Better education will help people understand more about the potential consequences of having sex as they relate to child birth. It will also do away with many of the myths that surround the sexual act and introduce scientifically-proven methods of birth control.

Access to contraceptives

Access to birth control must go hand-in-hand with better sex education. After all, without it people cannot put what they have learned into practice.

The World Health Organization (WHO) states that 225 million women who are living in the developing countries would prefer to postpone giving birth but are not using any form of contraception. Many organizations, such as the American Congress of Obstetricians and Gynecologists (ACOG), also support improving access to contraceptives.

Change in Policies

Many nations offer rewards, whether in the form of financial incentives or increased benefits, to those who have more children. This may lead to some couples having more children than they otherwise would if they needed to worry about the financial consequences.

Family Planning

As the population of this world is growing at a rapid pace, raising awareness among people regarding family planning and letting them know about serious after-effects of overpopulation can help curb population growth.

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.

Responsible and Innovative Agriculture

From poorly managed small farms, overgrazing and logging to huge commercial farms that exploit local water supplies and encroach on natural habitats, the environmental impact of agriculture are huge.

Responsible farming techniques, education and pressure from consumers can go a long way to improving this. However, if we want to keep producing enough food for a booming population, we need to start thinking differently about food production.

Adjust to an aging population instead of boosting childbearing through government incentives and programs.
