Population growth is an environmental issue that has significantly impacted our world, leading to higher demands for individuals to live comfortably. The demographic gap between developed and developing countries continues to broaden. According to research, developing countries consumed ninety percent of the population growth during the twentieth century.11 Overpopulation in underdeveloped countries is assessed with current research to determine some of the factors that play a role in the growth of the current population. Policies and methods are discussed for population control along with biblical principles and scripture that instruct how to properly address these problems in the environment.
Trends that are historical within human population growth are assumed that the first humans who appeared on Earth between one and a half million and six thousand years ago, it can be estimated that between six hundred and one hundred billion have inhabited the planet at some time.11 There are an estimated seven billion human inhabitants, which is close to seven percent of all who have lived on this earth.11 In 8000 BC it was estimated that the total population was about five million individuals. When agricultural settlements had become widespread, in the beginning of the Christian era, the population of the world had increased. The estimation includes 200-300 million individuals and which have risen to about 500 million by the year of 1650 then doubled to one billion by the year of 1850, then 4 billion by 1975.11 In the year of 1999, the world population increased to 6 billion and continually increases today as the growth of the world also rises.11 The growth rate of the world is considered in terms of doubling time, which is the required time that a population doubles in size. From 8000 BC to AD 1650, the population doubled every 1,500 years, doubling took 200 years, the next 80 years and the next, 45 years.11 The population has increased significantly during the past half century. However, the population increase has been very unequal across regions, specifically in Africa and Southern Asia. These regions have experienced some of the highest population rates and include a majority of the world's individuals who are living in poverty.2 According to research, these regions contain about a 4 billion population increase in size between the years of 1960-2010.2 Overpopulation is an issue that the world deals with quite often and is considered a debate to some and whether or not it is considered a success.2 However, researchers believe that only an ecosystem that thrives can sustain and generate a large population.2 Population growth can lead to overpopulation causing conditions consisting of containing more individuals than this world can completely hold. The expansion of the population in specifically underdeveloped countries has caused some of the most problems that are very difficult to handle at times such as poverty, climate change and higher death rates.11
Before the Industrial Revolution, birth rates were in the 40-50 per 1,000 range in every society, while today the gap in birth rates have varied significantly specifically in Germany and Taiwan, among the lowest in the world, compared to the highest located in the West African nation of Niger.11 Most of the countries that are advanced are generally are characterized by low birth rates.11 However, there are countries that still remain underdeveloped. Underdeveloped countries are characterized as high production with very limited technology and diversity of activities compared to those whose economy contains higher capital investment and lands that are rich.10 Other countries that are considered as underserved are in South and Eastern Europe, Asia, African and Latin America compared to developed countries such as India, Australia, some parts of North America and Europe.11 It is essential to recognize the different features among each of these countries. The developments of each country varies based on its economic expense and applies and plays a role in its growth overtime. Population growth is one factor that is that is considered especially when researching and conversing of countries that are underdeveloped and the high statistical evidence is figured out by multiple factors. These factors are important when trying to realize the consistent population trends specifically within countries listed above and others as well. The growth rate is the critical factor is one way to determine what is happening to a population in particular.11 Ironically, it is possible that a country could have a birth rate that is high and still have a low growth rate if the death rate is also high.11 Throughout this research, there will be focus on assessing the population and its growth with challenges and potential growth in the future. Also, including the growth in these countries and other specific ones, and going through factors that have impacted its growth and economic and social throughout the underdeveloped nations and their trends that are derived from recent studies.
There is quite a steady rate with birth rates, and the growth rate have steadily increased. The growth of population rates of the underdeveloped nations it very evident that essential variances affect the economy and growth rates of the countries and its increasing rates. There are some places such as Africa, Thailand, Malawi, Indonesia and others that are overpopulated and underpopulated. Both of these play a role in impacting the economic development.11,14 These stated are considered to be overpopulated and seriously impacted by poverty and its lack of technology resources. The population explosion resolve in underdeveloped countries and with the cultural advances among prehistoric humans probably minimized the death rate to some degree, however, the consequences of cultural evolution we minor compared to cultural revolution.11 Mortality rates have declined what researches thought to have been due to the general rise in standard living, the increase of food supply and "the more settled mode of existence."11 These features are fairly demographic in detail and are present in economies that are unfortunately impoverished and rely on agriculture that are less likely to spread at a rate that compares to the population that is rapidly increasing and therefore, causing living standards to decrease even lower.10 Agriculture is essential in underdeveloped countries and is a part of the way individuals in underdeveloped countries live.
Alongside agriculture, other gains included improvements for instance, the control of infectious diseases and public sanitation, which resulted in the decline in death rates, specifically with mortality with infants and children.11 Although agriculture is important, in the twenty-first century, boosting agriculture production within a growing population has been a major problem that Sub-Haran Africa has faced.13 Malawi is one country in particular that is very populated and has an estimated fifteen million people, whereby eighty-five percent of the population lives in rural areas and derives its livelihood from agriculture.13 However, considering Malawi and other countries do not have much room to expand under cultivation, agricultural production must be greater than it already so that enough food can be produced for the population that is growing so rapidly. This remains important because farmers are unable to utilize and increase their production with the modern uses of inputs and have little access to capital and technology that is confronted by numerous small holders, which may lead to high fixed costs of technology that is new and will eventually lead to assets and incomes that are lower and overtime increase farm output and yields.13 With the help of industrialization, it has increased levels of income, health care that has made progress and high productions of food, which each of these factors have caused an increase in the growth of the population. According to research, three conventional objects of policies concerning industrialization are mainly to offer work for population growth and however in some instances for agricultural populations that are under-employed already, improve balance of payment situations and also raise the living standards that is done by increasing the per capita net national income.13 It seems as if the growth of the economy in the near future would supply a majority of capitalization that is invested to what is needed to be sustained for the world's population. The capitalization of a climate and soil combined experience and producers who are well-organized has led to commercial production and agriculture that is very efficient.10 Obtaining land rights, titles and certifications is part of the process to rule your land and obtain rights that are essential in making sure that farmers have the security to enable them to proper develop their agriculture. In many countries, the property rights and such does not exist and various farmers utilize the land the state usually owns.
