Issues from Increasing World Population
The term “World Population” refers to the current human population of the world. There are 195 countries in the world today. The current world population is 7.8 billion as of January 2021. As research reveal that from the current 2020 population of 7.8 billion an increase of more than 25% is estimated to reach 9.9 billion by 2050.
Causes of Increasing Population:
Both domestic and global population rise is adding to conflicts over water, food, shelter, energy and wilderness, transportation infrastructure, school rooms, and numerous other problems, here are some reasons of overpopulation in the entire world.
- The Decline in The Death Rate
At the basis of overpopulation is the difference between the total birth rate and death rate in populations. The population will stabilize, if the number of children born each year equals the number of adults that die.
- More Hands to Overcome Poverty
Poverty is considered as the primary cause of overpopulation. In the absence of educational resources, coupled with high death rates, which resulted in elevated birth rates, that is why impoverished areas are seeing large booms in population.
- Lack of Family Planning
Most developing nations have a large number of people who are illiterate, live below the poverty line, and having no awareness about family planning. Besides, getting their children married at an untimely age increases the chances of producing more kids.
- Better Medical Facilities
Hi-tech advancement was perhaps the biggest reason why the balance has been permanently disturbed. Science was able to produce better ways of producing food, which allowed families to feed more mouths. Illnesses that had claimed thousands of lives until now were cured because of the discovery of vaccines. Combining the increase in food supply with fewer means of death tipped the sense of balance and became the initial point of overpopulation.
- Technology Advancement in Fertility Treatment:
It has become possible for couples who are unable to conceive to undergo fertility treatment methods and have their own babies, with the latest technological advancement and more discoveries in medical science. Today there are successful medicines that can increase the chance of conception and lead to a rise in the birth rate. Moreover, due to present techniques, pregnancies today are far safer.
- Higher Risk of Disasters and Pandemics
Many of the recent novel pathogens that have devastated humans around the world, including Ebola virus, COVID-19 and West Nile virus, originated in animals or insects before passing to humans. Part of the reason the world is entering “a period of increased outbreak activity” is because humans are destroying wildlife habitats and get in touch with the wild animals on a more regular basis.
- Agricultural Advancements
Developed revolutions and population explosions occur at the same time. There have been some foremost technological revolutions counting agricultural revolution which allowed humans with more access to food that leads to subsequent population explosions.
- Child Labor
It is no less than a tragedy that child labor is still in practice comprehensively in many parts of the world. As per the researches, approximately 150 million children are at this time working in countries having few child labor laws, the children being seen as a source of income for poor families.
Many people have a preference to move to developed countries, where the best conveniences are available in terms of medical, education, employment and security. The result is that those people inhabit over there, eventually making those places overcrowded.
- Problems Due to Overpopulation:
- Dreadful Conditions of Environment
With the overuse of natural gas, oil and coal, it has started producing some serious effects on our environment. Besides, the exponential rise in the number of vehicles and industries has badly interfered with the quality of air.
- Reduction of Natural Resources
The effects of overpopulation are quite severe. The first of these is the weakening of resources. The Earth can only generate a limited amount of water and food, which is falling short of the current needs because of cutting down forests, hunting wildlife in an inattentive manner, causing pollution, and creating a host of other problems.
- Rise in Unemployment
When a country becomes overpopulated, it gives rise to unemployment as there is smaller number of jobs available to support a large number of people. The rapid growth in unemployment results in wrongdoing, including theft, as people wish to feed their families and fulfill their needs.
- Faster Climate Change:
Overpopulation forces larger nations, to continue to develop their industrial capacities. According to 97% of the scientific community, human behaviors are changing global temperatures.
- Water Shortage
Fresh and accessible water is roughly 1% on this planet. Overpopulation is a major issue that creates huge pressure on the world’s freshwater supplies. As per the study, the human demand for freshwater would rise at approximately 70% of freshwater available on the planet by 2025.
- Conflicts and Wars
Overpopulation in developing countries puts a major damage on the resources it should be utilizing for development. Conflicts over water are becoming a source of pressure between countries, which could result in wars.
- High Cost of Living
The difference between require and supply continues to enlarge 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 carry on and feed their families.
- Increased Intensive Farming
With the enlargement of population over the years, farming practices have evolved to produce enough food mandatory to feed a larger number of people. However, this intensive farming methods cause damage to confined ecosystems and the land that may create problems in the future.
- Malnutrition, Starvation and Faming
When the availability of resources is scarce, starvation, malnutrition, along with ill health and diseases such as rickets etc become more likely due to diet-deficiency.
- Epidemics and Pandemics
Scarcity is associated to many ecological and social reasons, including overcrowded and unhygienic living conditions, undernourishment and inaccessible, inadequate, or non-existent health care, for which the poor are more likely to be open to the elements to infectious diseases. Further, high densities of population raise the chance of the emergence of new pandemics and epidemics.
