At the commencement of the 19th century, the cumulative world population spanned the threshold of one billion for the first time in the records of the homo sapiens. After then, growth standards have been rising exponentially, leading staggeringly very high peaks in the early 20th century and reducing down a little consequently. The cumulative world population approached 7 billion recently after 2010 and is assumed to touch 9 billion by the year 2045. Concerning each of the environmental hurdles facing the planet, today overpopulation is something that seldom slides under the radar.
Concerns like pollution, climate variation, and water deficiencies all appear to take priority, however, overpopulation is one of the chief contributors to various other environmental concerns. Overpopulation lays elevated demands on natural resources as well as land, leading to extensive environmental problems in enhancement to affecting global economies and living standards. The problem is combined with the challenge of rendering solutions for this difficulty and misinterpretation of the causes and consequences of the overpopulation.

What Is Population Explosion?
It indicates to the accelerated rise in the population of an area among human beings. Moreover, it is a situation wherein the economy is incapable of coping up with the growing demand of its current population.
Population Explosion Stats
The global human population increase amounts to almost 83 million yearly or it is 1.1% per year. The global population has raised from 1 billion in 1800 to about 7.774 billion in 2020. It is presumed to keep rising, and surveys have put the cumulative population at 8.6 billion by the mid-2030, 9.8 billion by the mid-2050, and nearly 11.2 billion by 2100.
The world population has been growing continuously following the edge of the Black Death, in the year 1350. The population began rising swiftly in the Western world at the time of the industrial revolution. The most notable rise in the world’s population has been since the 1950s, largely due to therapeutic advancements and improvements in agricultural productivity.
Population Growth Rate
The “population growth rate” is defined as the rate at which the number of people in a population rises in a specified period, represented as a part of the initial population. Population growth rate applies to the variation in population over a unit interval, usually represented as a percentage of the number of individuals in the population at the commencement of that particular period.
A positive growth rate symbolizes that the population is rising, on the other hand, a negative growth rate means that the population is declining.
A growth ratio of zero symbolizes that there remained an equal number of people at the commencement and end of the period—a growth rate may be zero indeed when there exist notable variations in the birth rates, death rates, migration rates, and age division among the two times. In 2017, the calculated yearly growth rate was nearly 1.1%. The surveys give the world yearly birthrate, mortality rate, and growth rate as 1.86%, 0.77%, and 1.09% sequentially. In the last 100 years, there has been an extensive quadruple raise in the population, due to therapeutic advances, lower mortality rates, and an improvement in agricultural fecundity which is made feasible by the Green Revolution.
The yearly rise in the number of prevailing individuals rose to 88.0 million in the year 1989, then gradually decreased to around 73.9 million in 2003, following which it raised again to nearly 75.2 million in the year 2006. In 2017, the human population rose by 83 million. Ordinarily, developed nations have witnessed a deterioration in their growth rates in contemporary decades, though yearly growth rates remain beyond 2% in poverty-stricken nations of the Middle East and Sub-Saharan Africa, along with South Asia, Southeast Asia, and Latin America.
In some of the countries, the population is decreasing, notably in Eastern Europe, largely due to low fertility rates, high death rates, and emigration. In Southern Africa, growth is decreasing due to a large number of AIDS-related losses. Some Western European nations might also encounter population deterioration. Japan’s population started deteriorating in 2005. This population growth is expected to reach all its boundaries in the upcoming years.
The Causes Of Rapid Population Growth
Until lately, birth rates and death rates were nearly the same, holding the population stable. People give birth to many children, but a considerable number of them died before the age of five. While the Industrial Revolution, a phase of history in Europe and North America where there were magnificent advancements in science and technology, the victory in reducing death rates was attributable to numerous circumstances: progresses in food stock and distribution, advancement in public health (water and hygiene facilities), and therapeutic technology (vaccines antibiotics and antimicrobial), along with increases in education and standards of living in many developing countries. Without these traits being in several children’s lives, they could not have survived frequent diseases like measles or the flu.
Mortals were capable to fight and remedy toxic germs that once killed them. Additionally, because of technology, individuals could create more and diverse kinds of food. Progressively, over a while, these developments and discoveries scattered everywhere the world, reducing death rates and increasing the quality of life for most people.
Specified below are some reasons responsible for population growth:
Food Production Distribution
The remarkable truth about the latest 15 decades has been the capacity of producers to enhance food production geometrically in various places. Agricultural practices have advanced in the United States in the latter two centuries. Enough of the world endured agricultural success, notably in the latest 50 years. Between 1950 and 1984, for instance, the volume of grain harvested globally has risen from 631 million tons to 1.65 billion tons. This signifies an increase of 2.6 times at a moment when the world population expanded by only 1.9 times. In more contemporary years, technology has created a wider variety of systems: unique kinds of seed, chemical fertilizers, pesticides, and more advanced machinations. The adoption of technology has made feasible the accelerated development of agriculture throughout the world. The application of pesticides, for example, was assumed to grow between 400 to 600% in the latest 25 years of the twentieth century.
Throughout the past 10 years, the world’s food generation has risen by 24 per cent, outpacing the scale of population increase. Nevertheless, this raise was not uniformly administered everywhere in the world. For instance, there in Africa, food production declined, while the population grew. And the world cereal generation dropped in 1993. However, most maximum specialists admit that there is no deficiency of food and that equal distribution should be enough to satisfy all requirements for them tomorrow. The shortage of money to purchase food is the obstacle of malnourishment. Poverty, in consequence, transposes the world capacity into national and local deficits. Within households, men and boys have a preference for whatever food is possible, while ladies and children, particularly girl children are the primary ones to experience malnutrition. Fewer resources are accessible to women, even though they are usually responsible for food supply.
Improvement in Public Health Facilities
People have concerns regarding enduring daily maintenance, such as satisfying basic needs: food, water, and housing. Prime, access to safe drinking water was associated with the incidence of pandemic illnesses such as cholera and child survival. Fewer than 50% of the population had admittance to safe drinking water before 1990. By 1990, admittance to safe drinking water had raised by 75 per cent. But between 1990 and 2000 the fraction of people having no access to safe water is predicted to develop. A growing number of nations both developed and developing are advancing the limits of sustainable water usage based on their renewable resources. Following, the necessity to give adequate housing raises as the population increases. More than half of the developing world’s population will be residing in urban cities by the end of the century. This increase surpasses the potential to accommodate housing and services for others. In some nations, locating a place to live is difficult, particularly for women. Some women and children are compelled to live in the poorest areas where they are subject to exploitation and abuse. The advantages of getting relieved of poverty, enhancing food supply, ending malnutrition, and rendering adequate housing correspond at all points with those needed for steady population growth.
Conquest of Disease
The most influential population account of the last century has been the conquest of infection. Scientists have discovered a magnificent deal about ways to counter and remedy various types of diseases. Thus, millions of people who would have fallen of disease a century ago are more probable to exist to old age. The most powerful means in the conquest of the disease have been enhanced knowledge about nourishment, vaccinations, better public health practices, and the advancement of new medicines. When growing children get sufficient of the right varieties of food, they are expected to live to be adults. In several countries, people know about proper nourishment for growing children and grown-ups. Regrettably, in many LDCs, the mortals lack the funds and skills that would enable them to utilize the knowledge about the nourishment they already possess. As a consequence, infant death rates and accordingly, overall death rates, persist high in several LDCs.
The second most influential factor is vaccinations. As far back as 1800, scientists comprehended how to employ vaccines to protect people from contagious diseases. The use of that consciousness has degraded the rate of diseases like influenza, smallpox, polio, and rubella in MDCs. Over, shortage of resources has hindered many LDCs from gaining similar use of immunizations to decrease the rate of communicable disease and death rates in their homelands. Furthermore, vaccines are yet not open for some diseases – malaria is the common obvious example and the biggest concern in LDCs.
Third, more reliable public health systems- the germ hypothesis of disease, discovered by Louis Pasteur in the 1870s showed that a person’s health was more a community problem. Sewerage discharged into a public water supply could cause disease everywhere in the area. With this knowledge, the sociology of public health was born. Today, public health agencies like waste treatment, water purification, vaccination, and nutritional education are well developed in MDCs.
Advancement in pharmaceutical science has, consequently, had a magnificent influence on the population of most countries of the globe. Nearly throughout death rates have dropped. At the corresponding time, birth rates, at least in the LDCs, have remained high. This succession of high birth rates and low death rates have commenced to the population explosion in many countries throughout the world.
The Industrial And Agricultural Revolution
The industrial revolution, as well as the agricultural revolution, had a significant contribution to the overpopulation concern. Considering the production of food along with the other goods grew quite due to the use of machines and the usage of fertilizers and pesticides, people were capable of raising more kids. Consequently, there had been an overpopulation spiral that has to lead to the emergence of a vast number of people dwelling on our planet currently.
Lack of Family Planning
Most developing countries have a considerable number of illiterate people, exist below the poverty boundary, and have limited or no knowledge concerning family planning. Getting their offsprings wedded at an early age raises the odds of producing more children. Those people are incapable to recognize the devastating effects of overpopulation and scarcity of quality education prompts them to shun family planning measures.
Strategies to Overcome Poverty
Nevertheless, when discussing overpopulation one should realize that there is a psychological element as well. For thousands of years, a very little fraction of the population had sufficient money to exist in comfort. While the rest of them dwelled in poverty and would give birth to a large number of children to make up for the high infant death rate. Families that have undergone poverty, natural disasters, or are solely in desperate need of more hands to work and this results to be another factor for overpopulation.
Impact Of Population Explosion On The Environment
The consequence of the overpopulation on the environment is definitely huge, however, the size of the population draws barely 1 viewpoint of this. In this respect, it can be helpful to retain in memory the mere I=PAT system: the eco-friendly footprint or results on the environment (I) can be considered as the product of the extent of the population (P), the accomplishment or consumption level (A for affluence) and the technology employed (T). The correlation between all of these factors is more complicated than the I=PAT system implies but in any case the footprint I of a population of 1000 people is, for instance, reliant on the number of people who drive a car rather than a bike, and of the emission of each car of the carrier line concerned.
The eco-friendly footprint of the overall world population has risen excessively in the past decades and the rise of the world population has certainly performed an influential part in this. The additional determinants in the I=PAT system have nevertheless played a comparatively more important role than the demographic determinant P.
If we are consequently concerned regarding the impact of the world’s growing population on the environment, we can do something about it immediately at an individual level by undertaking our personal overconsumption: it’s something that we can manage and it has a quick effect. In contradiction, we have an understanding of the population growth that it will proceed for some time haphazardly, even if people in underdeveloped countries would practice enough more birth control than we consider conceivable at present.
