The growth of the human population has been strikingly apparent that the rate of growth has been much steeper than recent times. The earlier Homo sapiens were vegetarians and gathers they hunted and fished for food. With increased knowledge humans learned how to farm, domesticate animals and used irrigation to meet their needs. The knowledge of water and sewer conditions along with better medical care and agriculture made life easier. Earlier man did not have these factors and the population remained stable, for over thousands of years.
The Toba super volcano is believed to have caused a massive environmental change. Creating a bottleneck of the human population that “occurred about seventy thousand years ago.” (Wikipedia, para. 1) This caused the population of man to decrease considerably and in turned the species that existed at the time became non-existent. This super volcano was the largest natural disaster at that time. “The exact geographic distribution of human populations at the time of the eruption is not known, and surviving populations may have lived in Africa and subsequently migrated to other parts of the world.”(Wikipedia, para 1) The population after the super volcano would have remained the same until the induction of agriculture. With the knowledge of agriculture, irrigation, and hunting the population thrived and grew.
A string of plagues created a decline in the population of humans. For example the Black plague would cause the termination of the European population killing an estimated 75 up to 200 million people towards the end of the 14th century. Another limiting factor would be bubonic plague it happened in the 14th century, and one fourth of the population was killed. Other factors are war,...

The Black Death caused the depopulation of about 1,000 villages in England. (Janis 2) In one case, in Alexandria, Egypt, the first two weeks of the plague 100-200 people died each day. Soon after, as many as 2,000 people died each day and the number increased each week. During this time, the Roman Catholic Church lost some influence on its people.
For instance, the human population trebled from about 1000-1350 and main reason is due to migrations (Davis, 245). Civilizations such as Vikings, Saracen, and Magyar migrated to Northern Europe and France (Davis, 250). Hence, the area of northern Europe and France was open and deserted and fully of resources such as food, animals and spaces (Davis, 250). Therefore, due to the affluent of quantity resources, this cause an attraction and driven a massive of people and civilizations to migrated in northern Europe and France. As results, there were increases and spread of population rapidly that filled the spaces and by 1300-1350 Europe was closed and the frontier was gone (Davis, 250). Furthermore, the drastic increased of human population in northern Europe and France led into a crisis of an economic and agricultural causing drought and poverty. Reason being there was a limitation and regulation. Limitation at some level of scarcity of one or more resources such as food, transport or space and regulation that brings the population to the limits set by the environment (Davis, 249). The increase of human populations totally occupied the deserted space and demands a higher quantity of food supply, in which creating a limitation and regulation in the population. For example, the pressure for land resulted in restriction of the use of forests, decrease in the size of the farms,
Is it right to think that population is a threat to the global environment? Is there indeed a direct correlation between population and environment? Is there such thing as overpopulation and who has the power to say that there is what they called overpopulation? These are some of the questions that are running through my mind. Now, in response to the question “Is limiting the population growth a key factor in protecting the global environment?” I with all conviction say no to that. I believe that it is the behavior of the people and not the population growth itself that affects the environment.
The appearance of the Bubonic Plague in Europe in the 14th century was the cause of a disastrous period of change in European culture and lifestyle. The Bubonic Plague ravaged Europe, killing over 60 percent of the population and is the cause of a series of political, economic and social upheavals. The effects of the plague on the decimated populations in Europe was the cause of a mass questioning of the effectiveness of political and religious authority leaders, a dramatic shift in the wealth of the lower class, and increased persecution and discrimination of Jews and other outlying groups in society.
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.
...lted in the decline of businesses. "The labor shortage was very severe and consequently wages rose. Because of the mortality, there was an oversupply of goods and prices dropped. Between the two trends, the standard of living rose, for those still living. Farms or entire villages died out or were abandoned as the few survivors decided not to stay on" (Knox). "The once positive outlook people had on the life of the thirteenth century had perished along with the many lives the plague took along with it" (Rowling, 188).
There were major shifts in human development over different times of human existence, two of
The human population growth rate is an alarming issue that brings with it irreversible consequences, that will likely effect the way of life for future generations to come. With the serious incline in population statistics comes catastrophic processes such as global warming and deforestation that have major ‘knock on’ ramifications. It’s issues such as these that need to be considered when we think about the growth of the human population, and we must take into account why these issues are occurring. We must also explore the options available to us that may assist in limiting the problems, or eliminating them all together, to provide a better place, not only for us in existence now, but also those who will walk this earth in the future decades and centuries to come.
Human Impact on the Environment Introduction = == == == ==
Fewer people mean fewer demands on the environment. With growth in human population, the grasses and animal populations humans used for sustenance did not have time to recover, which turned into humans using the earth's natural resources in an unsustainable manner (class discussion 02.14.03). Humans living in agrarian society do not necessarily use the environment's resources in an unsustainable manner, but the greater the population density, the more land will be needed to support that population in a sustainable manner. As resources become more and more scarce, field owners will be less willing to let land lay fallow (class discussion 02.21.03). Humans then found a "tech fix" with the development of agriculture and the domestication of animals.
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.
Around 60,000 to 70,000 years ago the human population nearly became extinct. The population went from around 2 million people to only around 3,000 people. Scientists think this was thanks to the combination of a super-volcano erupting and the ice-age.
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?
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.
