Human Overpopulation: Its Causes, Effects and Possible Solutions

Updated on December 24, 2014

People have been searching and finding ways on how to control the population growth of organisms. In regard to this matter, people search for an efficient way on how to skyrocket population growth of “desirable” organisms.

This approach is not a way to exterminate “undesirable” ones, but to lessen and improve life with better desirable organism like crops and livestock’s. In seeking how to lessen unwanted organisms that is caused by undesirable genes, people find ways to eliminate diseases that may harm crops and damage properties.

Today, we suffer from “population explosion” which means the world’s population has been booming rapidly in unwanted numbers. Looking back in history, the world’s population in 3000 BC was estimated to be about 200 million, but now the world’s population had gone up to 7 billion.

Due to the abrupt population explosion, numerous problems have evolved. Human problems have been growing in an alarming fast rate which may result to “overpopulation”. This overpopulation deprives person's standard of living. Below are some of the widely spread issues:

Food Shortage

Since the population has been risings more mouths need to be fed, without an increase of food production it causes deprivation and hunger which means a smaller amount of food is intake by each individual. In this manner, families with higher numbers might suppress their food intake for more mouths need to be fed. In analogy, a family with three children will be getting more food that the members of a family of ten. The effect of this is:

  • Starvation – due to a shortage of food, more people will be hungry, especially those who are unfortunate in life.

Possible Solutions:

  • Feeding programs – is some situation, most of the people who suffer hunger are those who can’t afford and buy sufficient for their bodily needs. The government and other private sectors have been doing precautionary measures in solving and lessening its number.
  • Charity works – aside from feeding programs some kind-hearted people and organizations are making movements in helping the lives of hapless people.
  • Government support – helping farmers with irrigation and production of crops and livestock’s will increase food production that will terminate food shortage.

Malignant Diseases

Big population can lead to new viral diseases because of some unhygienic practices of a man like an improper disposal of garbage. Due to the high number of population, disease-carrier organism can diffuse and spread fast in overpopulated areas. Some of these viral diseases which are very contagious and are malignant:

  • Cholera
  • H-fever
  • Typhoid fever
  • Viruses (Flu, Ebola etc)

Possible solutions:

  • Government programsDOH (Department of Health) is one of the main departments which are responsible in health related issues of the country. They have various programs and movements in order to prevent widespread of disease in the country.
  • Proper hygiene – one of the simplest way to avoid disease- causing organism is to be clean and hygienic at all times. Washing your hands before eating, taking a bath every day and eating nutritious food are some of the few ways to prevent disease-causing bacteria and viruses. These practices will boost your immune system to avoid unexpected ailments.

Do you think that there will be a time where people have no more space to settle here on earth because of overpopulation?

High Prices

Food shortage and diseases are amplified by the fact that medicine, food and daily necessities have fluctuated very high. As a result, poor families cannot afford to buy it, causing them to be vulnerable from diseases and problems such as famine and low standard of living. In solving this problem and to meet man’s increasing demand, plenty of industries and business have been built. But because of this move, another problem has evolved – pollution. Effect of high prices of food to man:

  • Famine – because of high prices of foods, poor people are deprived of eating and cause hunger and starvation
  • Deprive living – due to high prices of commodity, life of man is slowed down.

Possible solutions:

  • Increase employment rate – increasing the rate of employment and at the same time increasing employee’s salary will lead to elevation of the standard of living of poor families and as a result they can now afford commodities even in high prices.
  • Eliminate hoarding and unscrupulous businessman – some problems are manipulated by man. Some establishments are dishonest and selling overprice products, often times they hoard products when its demand is high and its supply is also high, but sell it when the supply is low and the demand is high.

Pollution means the addition of particulate matters (substances) to the air, water and soil, which yield harm to man’s health and cause harmful effects to other life forms. Because of overpopulation more waste is generated each day. Below are some of the causes of these different types of pollution:

  • Improper disposal of waste – results to any form of pollution.

(a.) Dumping of sewage and throwing garbage’s in lakes, rivers and other bodies of water can cause water pollution which may harm the aquatic life. Some of these are because of oil spills and toxic materials that can lead to “biological magnification” – is the increase in the concentration of harmful substances to toxic levels as it moves higher in the food chain.

(b.)Industries manufacture products which are non-biodegradable, which last for years or even in a lifetime. These products include: detergents, plastics and other synthetic products.

  • Smoke belching vehicles/industrial emission - That releases chemicals into the air, which eventually cause air pollution. Air pollution is widely caused by vehicular emissions, which may affect man and might cause respiratory system. Industries also one of the major manufacturers of carbon dioxide, which may lead to air pollution.

Possible Solutions:

  • Proper waste disposal – Obviously, the answer in order to solve common types of pollutions is disposing garbage properly, which will prevent air, water and soil pollution.
  • Use of biodiesel and eco-friendly gasoline – We cannot eliminate and stop the emission of chemicals in the air; however, we can lessen it. By using renewable source of energy lessened the emission of carbon dioxide and other chemicals in the air. Using biodiesel as for example, lessen smoke belching vehicles.

Population growth is drastically rising rapidly, which affects the life of man. But because of these the developments in the field of medicine have risen – new discovery of drugs and antibiotics, most modern equipments have been invented and more techniques have been developed which prolonged the life span of people. Because of these developments; fewer children die from malignant diseases and many diseases have been cured. Some factors that decrease the size of the human population are:

  1. Accidents
  2. Wars
  3. Natural calamities
  • Floods
  • Earthquakes
  • Volcanic eruption etc.
  1. Starvation (famine, hunger)

But should we wait for these things to happen just to reduce population? “A big “NO” to this” We can do something in controlling population growth. One of the most responsible entities in controlling population is the government. They must provide:

  1. Adequate food supply
  2. Adequate housing facilities
  3. Medical attention
  4. Employment opportunities

As what I have cited above, these issues and problem must be controlled or as much as possible should be eliminated for it will cause harm to the lives of man.

      As a pro-lifer, I am very much for a greater spread of human life, and a much stronger natural flow of babies into the world. I am against the evil NWO criminal elitists imposing population "control" upon people, and also against the RAMPANT CONTRACEPTIVE PUSHING of this wicked era. Humans should want for the human race to grow naturally and freely, because the more abundant humans can become, the more people around to benefit.

      There are places all around to put people, and so it would be good for human populations to freely grow and for more places to become inhabited. Let more babies be born and let world population density freely increase.

      Hi Sheila: I know and i can sense that my friend. You are a christian and very spiritual christian, as what I have read on your hubs and profile. That surgeries are true, men can have vasectomies to remove theirs and for them not to yield again (lol) especially those who have already plenty of children, for women its tubal ligation.

      It's a choice but because of unexpected pregnancy and night stand and other earthly lust population keeps on growing.

      Ken: I would never want to decrease the population by abortion. Another idea I've heard thrown around is hysterectomies or vasectomies for those people who already have a set number of children. I wouldn't approve that either. People should always have the choice to have children. Education seems to be the way to go. Let people make wise choices based on the facts about over-population.

      Hello sheilamyers: Probably you have the point but decreasing the number of babies born? How? Are you trying to open up the abortion and misconception? Giving birth is a God's gift and we cannot force to lessen it the only way it proper education I guess but decreasing number of babies in a bad way is not good.

      Hello MercCipher: Yes, and still counting. I hope that time will not come when the world have already food shortage. It will really cause a bit outrage!

      Overpopulation won't be decreased by better medical care, providing food to the starving, and curing diseases. Those things mean all of the babies that are born will survive and the population will increase even more. I'm NOT saying we shouldn't do those things, just pointing out a fact. The only solution to overpopulation is a decrease in the number of babies being born and I certainly don't want the government supervising that. But what happens when the number of children decrease? It's been seen in some areas of certain countries. The average age of the population gets older and there is no one young enough to be working and paying taxes etc which means the retired people can't get their benefits and you're back to starving people even though you have a smaller population. I'm not sure where the middle ground is, but that's what we need to find.

      There's at least 7 billion people in the world and it keeps on growing. The world can't sustain so many people. Eventually, food and water shortages will take place and their won't be enough living space.
