“I would be absolutely astounded if population growth and industrialization and all the stuff we are pumping into the atmosphere hadn't changed the climatic balance. Of course it has. There is no valid argument for denial.” -David Attenborough
There has been a growing trend established with the growing population seen in hunger, warfare, and pollution: they are all rising. It is expected that earth’s population will rise to nine billion by 2050, and to ten billion by 2100. It can only be assumed that along with a higher population, more people will go hungry, more countries will go to war, and population will be the highest the world has ever seen. Pollution, hunger, and warfare have no exact date as to when they began. We do know, however, that these are concepts seen in humans, and can date back to when humans began, about 200,000 years ago. With more people, comes more litter and hazardous waste being pumped into the atmosphere, a rise in differing opinions, and not a sufficient amount of food to feed everyone. Pollution, warfare, and hunger are caused by a high global population.
With an increase in population there is bound to be an increase in warfare. One main cause of war is very diverse opinions, such as religion and cultural beliefs. More people will lead to raised amounts of varied opinions on such subjects, thus boosting warfare. The Korean War can be taken for example. North Korea was a communist country, trying to force South Korea to acquire the same form of government. South Korea, which clearly disagreed, fought back. Another prime example is the Philippines. They were controlled under Spain for 334 years, until in 1898 when the United States took it over in the Spanish-American war. A year later, the ...

In, The Population Bomb by, Paul R Ehrlich, he explains the problem of population increase, and how there are people everywhere! The feeling of feeling over populated. He talks about how if there are more people then there is more food that needs to be produced then ate. He explains on the rich people becoming wealthier and the poor are going to be even poorer and there is going to be a starvation. Population is doubling every year and how our energy is turning into
As small mobile groups of hunter-gatherers adopted a sedentary lifestyle, they mastered both agriculture and animal domestication. These small settled groups quickly evolved into cities and towns that encompassed the entire globe. Today the estimated population of the world is over 6.2 million people.1 As the population has grown, it has had several deleterious effects on the Earth. These include climate changes, the spread of diseases, declining food production, deforestation, and environment pollution (particularly air pollution). As people have become more conscious of these harmful effects, they have begun to devise strategies to combat this problem. Among the suggested responses include a switch to renewable energy, a call for zero population growth, and adopting sustainable agricultural practices.
Population growth affects the earth just as much as it does the people. With the population continuously growing at an alarming rate, earth can’t keep up with the resources needed to survive. Eventually we will run out of oil, land to build houses, and air. The reasoning behind running out of air is if the world is covered in houses, there is no room for trees – which supplies our oxygen. The factors effecting population growth are: fertility rates, life expectancy, migration, and death rates. More and more people are migrating to North America because of the high life expectancy, average fertility rates, low mortality rates, and of course, job opportunity. Even though population growth isn’t as high as it used to be, overpopulation can still
and is existing surely because of humans themselves- overpopulation. “Overpopulation is the problem” and causes other externalities such as pollution, deforestation, and a greater handful of biodiversity losses. In addition, overpopulation causes economic and political factors such as more consumption per person and the reduction of resources that can be provided per person. This contributes to the strain on ecological systems and the economic and population growth. With overpopulation, many resources become finite and an umpteen amount of ecosystems are being destroyed. Overpopulation relates to the impact of humans on pollution. Obviously with more human life, there is more necessity for jobs such as factories that give off fumes, automobiles, and the use for burning fossil fuels. In greater extent, this leads to an environmental factor in that it accumulates chemicals in food chains such as mercury, arsenic, and copper. It can lead to political problems as well, when trying to interact with other countries and stop the problem of global pollution and eventually endin...
Have you ever wondered why there are 7 billion living on earth today? According to Webster’s Dictionary, population is the total number of people inhabiting a country, city, etc. (Merriam-Webster). There are a lot of people in the world and the earth doesn’t seem big enough to sustain the growing population of the earth. Having this many people on earth is too much so something must be done about it because it can cause a lot of problems in many countries especially in less developed countries. There are many ways of making the world a better place and overpopulating is not one of them. Even with the knowledge of its history, causes and effects, it is still a topic that is a major concern today.
It is a known fact that the world population is increasing without bound; however, there is a debate if this increase is a good thing or if it will prove catastrophic. The article “The Tragedy of the Commons” by Garrett Hardin discusses how the ever-increasing world population will exhaust the world of its natural resources, and eliminate human’s capability for survival. On the other side of the argument is Julian L. Simon who wrote “More People, Greater Wealth, More Resources, Healthier Environment.” This article proposes the theory that with an increase in population, humans’s quality of life is amplified. One particular issue that they both mention and have drastically different views on is the future of agriculture and human’s ability to sustain it.
Humans have greatly impacted the global environment. Throughout the course of history, human populations have rapidly increased. Especially in Africa, these numbers have reached extraordinary proportions. Out of all the continents in the world, Africa’s population is increasing the most. The type of growth here is exponential. “Overpopulation is a condition when an organisms numbers exceeds the carrying of its ecological niche.” The growth rate of a population is equal to the birth rate minus the death rate. Therefore, for overpopulation to occur, the birth rate must surpass the death rate (Wiley). The current population of Nigeria is estimated to be 155,215,573. Most of the population consists of the younger generation. More specifically, 41% of the population is between the ages of 0-14. 56% of the population is between the ages of 15-64. However, only 3.1% of the population is 65 and over. This age group represents a very small part of the population. (CIA)
There is no longer any question that our world climate has changed (King, 2004). Over the last 100 years, "temperatures have risen by about 0.6 degrees Celsius and global sea level has risen by about 20cm" (K...
For these reasons, global warming stands as one of the most daunting policy issues facing our world today. This is compounded by the debate over the very existence of climate change. While countless sources of empirical evidence testify to the very real presence of climate change the world over, considerable denial of the phenomenon still exists. The argument has been made that evidence about climate change is a gross overstatement, or in some cases, a complete fabrication. Despite the evidence to the contrary, many interest groups with considerable political clout have successfully perpetuated the argument that documented changes in the environment are a product of natural cyclical changes in climate, and are not associated with human activities. However, even the acceptance of this particular brand of reality is no grounds for the disregard of environmental consciousness. Even if one accepts the premise that recent climate change is not resultant of human activity, the rationale behind environmental conservation remains ...
Human population growth is becoming a huge issue in our world today. The population is increasing rapidly. The reason that it is becoming a concern is because it has affected the economic, environmental, and social aspects of our world. In the film Frontline: Heat, we can see how there might not be a future for our planet unless we are able to reduce the emissions and make our world a safe place. Not only for the present but also for future generations so that they are able to live long and healthy lives.
Human population growth is the leading factor we have in place to sustain a more perfect ecosystem for future generations. Over development has led to extinction, habitat loss and climate change that scars the Earth and will never be recovered again. According to the Center for Biological and Diversity we are adding 227,000 more people on top of the 7 billion everyday which is causing species to disappear 1,000 to 10,000 times faster than the rate of natural selection. It is time we get over our greed, religious biases and having more children equal’s more money mentality. The Earth and its ecosystem should be protected by every individual to keep it as pristine as the day they were born to pass off on future generations to inherit.
Our world is too small for our ever rapidly growing population. One day resources will run dry and vanish, which will bring death and loss to all nations on this planet. Many researchers and scientists have confirmed that the population will reach 10 billion by the end of the century and will continue to stream upward. There are many different ways in trying to decrease population to contain global warming and assist our environmental changes. The only way to steadily succeeding, families must be the regulators of their fertility and future. Environmentalism can head in a negative direction, which may result in population control and even anti-immigrant policies. Can the developing effort of ‘population integrity’ protect our world while recognizing birth moralities?
Globally, the growth rate per person of the human population has been declining since its increase in 1962 and 1963 which was at 2.20%. In 2009, the estimated annual growth rate was 1.1%. As of now the population of the world is at about 7,211,021,348 humans, which has gone up 4 billion people since the 60’s. Most of this growth is coming from the countries in high poverty. Rise in human population can cause problems such as pollution and congestion; these might be resolved or worsened by technological and economic changes. Over the last 100 years we have seen a fast increase in population due to medical advances and massive increase in agricultural productivity. The major fear is that high population numbers are putting a burden on natural resources, food supplies, and more.
One of the problems facing our world is population. It began about ten thousand years ago when the humans settled and began farming. The farming provides more food for the people thus making the population grow. Now we are about 6 billion in population and in a few years we will be around 10 to 11 billion. Therefore, our population will almost double in size. This means that we will need more food to support us. A study in 1986 by Peter Vitonesk, a Stanford biologist, showed that the humans are already consuming about 38.8 of what is possible for us to eat. Thus, if the population keeps increasing, the percentage will increase also, making us closer and closer to the biophysical limits. By studying the earth's capacity, Dr. Cornell, another biologist, believes that we are already crowded for this would. He believes that our world can only support two million people. Not only this, but population can cause complicated problems to the countries with very high population. These countries will need more schools to educate its people, they will need more hospitals and public health to take care of their people, and they will need more water and more soil for farming to feed all the people. In order to solve the population growth problem, the people should be educated. Once the people are educated they will be aware of the problems they ca...
The reduction of the Earth's resources has been closely linked to the rise in human population. For many thousands of years people lived in relative harmony with their surroundings. Population sizes were small, and life-supporting tools were simple. Most of the energy needed for work was provided by the worker and animals. Since about 1650, however, the human population has increased dramatically. The problems of overcrowding multiply as an ever-increasing number of people are added to the world's population each year.
