Essay on The Earth's Carrying Capacity for Humans

Population Growth is an issue that exists in today’s world that needs to be confronted before it becomes out of hand. The population itself has reached overwhelming numbers making it a problem that could turn to be dangerous. The amount of humans that the earth can support or the carrying capacity is slowly rising but at a much slower rate than the population growth rate. The increasing growth rate has its negative effects environmentally, agriculturally, socially, and economically and also has its positive effects nationally, and economically. The government is brainstorming and trying to come up with ways to decrease

Overpopulation, pollution, global warming, climate change, genetic modification, ocean acidification, water/soil pollution, deforestation, acid rain, and ozone depletion are among some of the main factors that have a negative impact on the planet. Overpopulation is one the most concerning environmental issues currently. Overpopulation is defined as the human population of a specific area exceeding the carrying capacity. Overpopulation can occur from an increase in births mainly or a decline in deaths. Also, other factors that affect overpopulation can be an increase in immigration or a depletion of resources. It was stated by the United Nations that the worth has a total carrying capacity of somewhere between 4 and 16 billion. Currently we hold over 7 billion humans on Earth. As of 2017 the UN has increased their population predictions to 9.8 billion by 2050 and up to 15 billion by 2100. Pollution we hear about every day.

The cause of human overpopulation is birth rates. The high amounts of birth rates are causing overpopulation to grow each year. Research shows in the year 2030, the population is expected to reach 8.5 billion people and 9.7 billion people in the year 2050. Developing countries is straining the already scarce resources. Intensive agriculture practices damage the environment through the use of chemical fertilizer, pesticides, and insecticides. As the population expands further, many natural resources such as fossil fuels, water, and forests continue to plummet. Lessening population will definitely solve many problems such as poverty, species becoming extinct, food shortages, water and air pollution, and even lower crime rate. High birth rates can be solved by spreading awareness, educate people about overpopulation, and increasing accessibility to birth control.

In October 2011, the United Nations announced that the world's population had reached 7 billion. By the year 2050, the UN predicts that the population will increase to about 9.6 billion. Our rapidly growing population has many concerned about whether or not the Earth can sustain more than 7 billion people. Many people are worried about what the human carrying capacity is and what will happen if we exceed that. Others believe that we will continue to be able to support population growth through innovations in technology. Erle C. Ellis, a professor of geography and environmental studies, holds this belief and presents it in his article "Overpopulation Is Not the Problem".

Thesis: The topic of human population growth is an important issue due to its impacts upon people in developing countries, economics, religion, food production, and the environment; without any limitations, population growth can lead to negative consequences, such as famine and environmental destruction, or even positive outcomes, such as potential economic growth.

There are more than seven billion people on Earth now, and about one in eight of us don’t have enough food to eat. So, with a projected nine billion people by the year 2050, how many people can the Earth support while maintaining a healthy population? Population changes are due to the relationship between births and deaths. If the number of births equals the number of deaths then the world’s population will remain the same, but if births exceed deaths, population growth will occur. Early in history, population was slowly growing because of high death rates related to wars, famines, and poor medical services. With advances in

The article by Dennis Dimick brings up some very good points about the increasing population. He states that with our current population of 7 billion people, we currently do not have enough food to eat. With the population increasing day-by-day, we will face more shortage in the future. He also brings up the issue of natural resources. We are currently using so much natural resources that we will run out very soon. The use of natural resources tend to increase with increase in social standing (wealth).

It is obvious to see in today’s society that the world has changed so much compared to the last decade and the many years before that. As time moves forward, the human population also grows along with it. And as the population steadily increases, the environment also deteriorates and becomes heavily impacted by the negative effects of overpopulation. Humans are the main cause behind every damage inflicted upon the world. With the rise of overpopulation, along with the countless number of humans already existing, the world will inevitably suffer severe damages. The world, without a doubt, would be so much better off with a limited number of humans as more would only bring it its demise faster.

Overpopulation can damage or even destroy the environment. The need for resources will grow with the population, but natural resources will not be produced at a fast enough pace. Man may try to produce the resources they need themselves but will there be enough space? According to Young the average person needs a minimum of 100 square feet to feel comfortable in a living space (“How Much Space Do You Really Need?”). Using the estimated population size of 2050, human living space will take up 43.8 billion square feet. Assuming most of these people live in apartment buildings so there is room for farming. Farms will need to switch out crops every year to slow down the process of soil degradation.

In biology, it states that when life is pleasurable and resources are abundant, life will begin to grow exponentially until space and food become scarce. At that moment the population of whatever creature will even out and remain stable. However, in nature, land and resources are limited, so all forms of life are in a constantly competing for survival. Adaptability and evolution helps the lucky certain creatures with new skills or traits that will aid them to become fit and reproduce. With the early humans, their numbers began to grow dramatically due to their involvement in agriculture to produce their own food in vast amounts. Then, as man's tools and farming techniques were developed to produce more food, the human population grew dramatically, again. This allowed a civilization to trade

Every population has shifts in it’s growth rate, it’s part of how natural ecology works. However, when a population experiences an exponential growth, measures must be taken to control the growth. One of the most notorious examples of this is China; with its one child policy, China was able to bring control back to it’s large population. Subsequently, there was a decline in the economy and relative personal net worth due to not only the rise in population, but also due to the government’s attempts to control it.

Over seven billion people live on the planet Earth. That is four billion more people on Earth today than around 57 years ago (Smith 1). Over time, humans have had many technological advancements which increased the rapid depletion of renewable and non renewable resources such as water, food, and space. This, causes scientists to believe that the more people on the earth, the more we are going to run out of our resources. Although, many believe that Earth is quickly reaching its carrying capacity from the depletion of resources, that capacity is not within reach because the Earth has enough resources to sustain a much larger population than what is prevalent today.

Each year the number of human beings increases, but the amount of natural resources which to sustain these populations,

The topic of overpopulation has different perspectives regarding whether or not it is happening as well as its apparent effects of both the environment and its inhabitants. The idea of human overpopulation being a problem most clearly begins around the time of Thomas Robert Malthus’ publishing of An Essay on the Principle of Population as It Affects the Future Improvement of Society, with Remarks on the Speculations of Mr. Godwin, M. Condorcet, and Other Writers. In his writing, Malthus describes how the growth of the human population will always outgrow the resources required to maintain it. “The increase of population will take place, if unchecked, in a geometric progression, while the means of subsistence will increase in only an

In this day and age, our world is being consumed by the rapid growth of the world’s population. From the beginnings of time with cave men thousands of years ago up until the Industrial Revolution, the number of people living on this planet never passed a billion, and was always growing at a slow pace. When the Industrial Revolution hit the population skyrocketed to over 7 billion people. The growth of population has not slowed down since then, and more technological advances are popping up everyday to help balance the rapid growth. The amount of people in the world is literally growing each and every day. As the population grows we put more demands on our planet to provide for the billions and billions of people inhabiting it. The world
