Overpopulation Research Papers Samples For Students

If there is one thing that is more dangerous than nuclear wars feared by many, it is overpopulation that can trigger not only wars, but also a variety of other issues. An increase in population puts strain on water and food, as the bigger number of people will require the satisfactions of their basic needs. To distribute sources available on the Earth on a fair basis, people have created social institutions and elaborated codes that regulate the amount of resources people can get, based on their contribution to social welfare and social usefulness. In other words, people receive financial retribution equivalent ...

Effects of Overpopulation in Our World Today

Overpopulation occurs when global limited natural resources fail in sustaining its population. The world's population has increased tremendously, and estimates suggest the world population will be six billion by the end of the 21st century and 10 billion by the year 2040 (Jakab, 2008). This expansion creates challenges and this research study seek to address the effects of overpopulation in the world today. Population growth affects natural resources negatively such as water and land. Since natural resources are scarce and limited, overpopulation will strain and drain them with consequences such as the extinction of species. As population increases space ...

According to the most recent available statistics, the earth’s population has passed 7 million. The debate over the threat posed by overpopulation has raged for decades and the true magnitude of the situation may not be known for some time. However, there have long been observable, measurable consequences to the environment, living space, replenishable food supplies and other basic resources. In Brazil, all of these problems are in evidence to varying degrees, but poverty remains the overriding factor. While it cannot be argued that overpopulation is the cause of myriad social and political problems, in Brazil it is ...

Introduction

Human activity on the natural resources causes threats to the land sustainability either directly or indirectly. This paper examines soil erosion, genetically modified grains and overpopulation as the main threats to land sustainability.

Soil erosion and how it impacts the global food supply

Soil erosion is the washing away of the earth’s topsoil by agents such as wind and rainwater, and it occurs mainly due to human activities. Agriculture is the primary cause of soil erosion. When people clear natural vegetation to create framing fields, the topsoil is exposed to erosion agents such as the wind. Deforestation is also a leading contributor of soil erosion. As people cut ...

Introduction

Overpopulation has become a global concern. In 1650, the world population stood at only 500 Million. The human beings had only been in existence for a period of a million years. In the next two hundred years the population doubled! Now the people were in the range of 1 Billion. After that the population growth was even more staggering. Within the next 80 years, the population had again doubled to 2 Billion people. It took almost forty years for the population to double again to four Billion. Clearly, the world has to deal with the situation because the resources that the population ...

Demography is one of the most important components of sociological knowledge, both theoretical and empirical. In empirical researches, the demographic component is lex non scripta! Today the main problem of the science of demography and all world community facing with – overpopulation of Earth. The subject of an overpopulation at first glance is rather clear and simple but not everything is so simple, and it is necessary to understand it. Usually, it comes down to several aspects: 1) the lack of space on the planet; 2) lack of resources; 3) lack of food; 4) global warming.
However, unfortunately, demographic ...

Human overpopulation presents one of the most pressing social, political and environmental issues in the modern world, dramatically aggravating the forces behind environmental pollution, global warming, mass extinction, loss of natural habitats and overexploitation of finite natural resources. According to McKibben (34), fresh water is the most important finite natural resource with no immediate substitute for most uses. Yet, this resource is being depleted at a higher rate than is being replenished. As the human population expands, the amount of fresh water available decreases, which puts the human species at a great danger. It is estimated that by 2030, ...

Introduction

China is the world’s most populous country. Its population comprises roughly 20 percent of the total world population. It is also a close second to the United States in terms of the size of economy and a close third when it comes to military size and even military technology sophistication. Over the past decades, the People’s Republic of China has slowly but surely gained strength to become a regional superpower, both in terms of economic and military benchmarks, especially when the fact that it is still being considered as one of the fastest growing economies not only in Asia but ...

A general move to broaden the security agenda occurred during the 1980s by expanding the focus from the security of the state or the nation to an alternative focus on the security of the people, or the global collective. The human security can be affected by economic welfare, environmental concerns, cultural identity, political rights, and military issues. In recent years, environmental degradation is increasingly being considered as a security problem by not just the environmental activists but also the security establishment as they have become more responsive to the idea. In late 1989, the journal of the International Institute ...

Abstract

Mental illnesses account for one of the oldest but least understood health issue facing the human race. The ancient Romans and Egyptians considered mental illness to be a manifestation of demonic possession. The same belief was carried on to the Middle Ages, as well as during the Renaissance. In America, this belief only changed in the last years of the eighteenth century. The belief that spiritual possession caused mental illness resulted in treatment procedures being inhumane. Most of these treatments involved the isolation of patients from the public. However, as people become enlightened, the modes of treatment changed, with ...

Introduction

The increase of human population is a grave issue that is growing by shocking geometric progression. Each day, about two hundred thousand people die but in the contrary, about four hundred and fifty thousand others are born (Jones, Schoonbroodt & Tertilt, 2011). Indeed, this indicates that there are about two hundred and fifty thousand new people to feed each coming day. However, it is very hard to support infinite population growth on a finite planet; resources are becoming scare with each coming day. In this regard, a debate has come up, which rotates around two basic questions: whether an increased population is bad ...

Analysis on the Globalization in China

Coast Fishery and the West Coast Salmon Fishery

Introduction
History has it that the East Coast also known as Northern cod was one of the largest fish hubs in the Northwest Atlantic. The term East Coast Fisheries, arose from the sailors who had found the fishing grounds on the Eastern Coast of Canada. The entire communities greatly relied on fishing for their daily activities (Shield 22). No one ever imagined that the fishing industry would near extinction. Canadians and foreigners who had found great resources, generated a lot of revenue from the exercise, and this led to overfishing. Although Shield (23) believes overfishing was the reason to ...

Malthusian Theory of Population

Introduction
Ever since it was first presented to public in 1798, the anonymous little tract “Essay on the Principle of Population” has profoundly influenced the peoples’ vision of population and other demographic, economic, and, more recently, environmental issues. Produced by Thomas Robert Malthus in the midst of Victorian England’s Industrial Revolution, the concept outlined an important and fascinating correlation between population growth and what was termed to be ‘subsistence.’ Author’s main argument was that population was expanded at ‘geometrical’ rates, when subsistence was increasing at an ‘arithmetic’ ratio exclusively. Malthus strongly believed the man’s ability ...

Introduction

The Rwandan Genocide of 1994 was one of the massacres that country witnessed in the course of its history. The genocide was responsible for the death of approximately 800000 Rwandans in a span of only three months. This death toll translated to about three quarters of the Tutsi community, which was a minority ethnic community in Rwanda. Ever since Rwandan’s colonization, ethnic composition played a significant role in shaping the political structure of the country. This implied that Belgium colonizers had a great impact on influencing the genocide that took place during 1994. With this regard, the principle cause of the genocide can ...
