Without Earth’s limited resources, the human race would not be able to exist. Our planet supplies us with the food, air, water, and other necessary resources to ensure our ability to survive. Unfortunately, these necessities are not guaranteed to be infinite and could eventually become insufficient to human needs. As Earth’s human population increases, more and more resources are required to be used to ensure survival. I believe that human overpopulation is detrimental to the planet and equality among the human race.
Rich and developed countries, on the other hand, have sustained the limit of the population growth. Controlling the population means two opposite things, the effort to increase or decrease the number of people in each and every country. In countries which lack development and where a very high rate of poverty is present, control of the population is a necessity, and poverty has a direct relation to population growth. It cannot be automatically stopped or completely prevented, and when it grows, there are chances of high competition among the members of the population, leading to war or disputes between countries and thus, reducing the total number
Introduction Does human population growth affect our world? This has been an ethical dilemma for scientists for many years, and it seems they don’t have any solution to it yet. Human population growth has brought a lot of effect on our world, negative and positive impact. It depends on the environment of the specific area, for example, if an area is under populated, it will need population growth to have the man power in that area ( Aiex, 1994).If the area is overpopulated, population growth will be hazardous because there will have scarce resources in that particular area. In this essay, I will discuss two sides of the dilemma examining each position (pro and cons) critically.
World population has been increased significantly, while Earth resources are limited and food sources are in danger. In this regard scholars predicted that world’s population would be reached around 10 billion by 2050 and certainly food requirement would be increased more than 70% (Dyson, 2016).These statistical data imply that food sources are increased arithmetically, while population are enhanced geometrically, whereas there should be a balance between population and food supply (Brownell, 2008).To overcome food shortage, some attempts have been done around half century ago which led to green revolution. This paper, aims to have a look on this phenomenon, introduce it and assess pros and cons of it. In this essay, initially, we have a quick look on nature and evolution of green revolution. Secondly, pros and cons of this phenomenon would be discussed and then more holistic solutions for improving this process would be introduced as a real green revolution.
This striking growth was largely caused by an increase in the number of people living in the age of fertility and accompanied by significant changes in fertility rates, which increased urbanization and accelerated migration. These trends will have broader implications for generations. In this study, we will examine the causes and effects of rapid population growth and the studies that the United Nations has done for the solution of this problem. First, we will examine the reasons for the rapid population growth after the information on the regions where the population growth rate is high and the population is intensive, and finally the studies of the United Nations for the solution of the problem. Summary of World Population China and India: Most Populated Countries Sixty percent of the global population is in Asia (4.4 billion), 16 percent in Africa (1.2 billion), 10 percent in Europe (738 million), 9 percent in Latin America and the Caribbean (634 million)
Malthus said that the rate of population growth was much higher than the increase in food capacity needed for human nutrition, which inevitably creates a crisis. Malthus, who exemplifies the population growth in the United States, in particular, has suggested that if the population is released, the population will increase one time every twenty-five years. According to this, the balance between the population and the foodstuffs is deteriorating and the difference between population growth and sources must be
In the past century, the globe’s population has expanded rapider than ever in human history. Facing this population boom, scholars in the past few decades have discovered certain problems of overpopulation. Many of them put their focus on China, the country with the world’s largest number of population, which was having difficulties in development after the Cultural Revolution along with the massive, almost incontrollable large number of ever-growing population. To solve this problem, the Chinese government established the well-known one child policy, which played a huge impact throughout the past three decades. Although population growth rate has now been controlled, the problem of overpopulation is not yet resolved, and the policy has brought in many social and economic problems.
According to the UN’s calculations there are more than 7 billion people on the earth today when 200 years ago there were less than 1 billion. Populations have grown 3 times faster between the 1900’s and 2000’s (Ortiz-Ospina, E, & Roser, M, 2016) Rapid population growth is a cause for alarm because of many factors. The drastic increase in population could cause detrimental factors for societies and the world as a whole. Factors including environmental strain, governmental strain in producing services, cramped and unhealthy living conditions. A city or countries population can grow because of many reasons such as migration, increase in birth rates and decrease in death rates.
Population is a huge problem in the community todays. Population growth can be defined as an increase or decrease in the population size of living species including human beings and other species. Human populations are also subject to natural process of birth and death. Population is the heart the earth that run the entire globe. The country I chose was India as they have a vast amount of population in the country for various reasons.
