Essay Population Growth, Industrialization, and the Environment

2,000 years ago the world, in terms of population, was only the size of the United States of America, 300 million people. Today, the world’s population is at seven billion and counting. If the population rose at a steady rate from year 0, we would’ve reached 1 billion people by about 210 A.D. This, however, was not the case. We reached 1 billion people in 1800 A.D, which means that there had to be very odd growth periods for the population as a whole REWORD ME. From 0 to 1000 A.D. the population only rose about 10 million people, “and well into the second millennium, [the population] grew less than 0.1 percent each year” [1]. However, from the year 1800, with 1 billion people worldwide, to 1930, the world gained another billion people. We then reached three billion people in 1960, five billion in 1987, and 7 billion in 2013. One can clearly see that once we entered the 19th century, the world’s population started growing like a 14 year old boy going through puberty; rapidly, and without any warning. One thing that can explain this growth is called the Demographic Transition.The Demographic Transition is a theory that explains the growth.

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

The human population rate has changed throughout the ages. By looking at the table we were given the human population has increased heaps from 2000 years ago. If we look at our ancestors they lived with a small existence but this has changed as we have developed and there is more agriculture in this world. Population grew very slowly in the 1000 A.D. also decreased after the Black Death causing large numbers of people wiped out. Then in the 1800 A.D. the industrial revolution came, soon living standards were raised and there was food shortage with the population. In 1927 medicine was introduced this meant that there was increased life expectancy, so the human population grew more. There was more advantages from agriculture, medicine and sanitation

Industrialization and urbanization advanced many aspects of life in the United States at the turn of the 20th century. Emerging technologies in a post-war America in addition to ready resources and a work force were integral to these advancements. Improvements in already existing institutions such as companies allowed the expedition of material goods and journalism. Steel was a primary be resource for most foundations during this era, while newer forms of energy were adapted for contemporary use. These new developments created new means of expansion and living both nationwide and for cities. Industrialism also served to standardize prior methods of transport, such as the locomotive.

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.

Compare predictions for human population growth in developed countries versus developing countries. Why is it difficult to predict the growth of Earth’s human population? Why should population growth be predicted?”? What will happen if there is exponential human growth?

Forests have been cut, crops planted, pastures seeded, and urban areas paved. One of the most troubling consequences of human modification of ecosystems is an ongoing loss of species and therefore a loss of biodiversity around the world. The current extinctions have a human cause: habitat loss (such as clearing of tropical rainforests); the introduction of invasive species; unregulated hunting and fishing; and pollution of water, air, and

As the human race continues to grow older the population starts to grow. Population growth is a change in the size of a population over time, depending on the balance of births and deaths over a period of time. For the world, population grows when the amount of births exceeds the amount of deaths. As shown in figure 1, the world’s population grew very slowly until about 1750 that is when the population growth started to increase rapidly. Figure 2 shows the growth of the global population from 1950 onwards, it also shows the projected population growth up to 2050. The global population is estimated to rise to approximately 9 billion people by 2050.

According text one, Population Trends between the years 1700, to an estimated 2100 as the years go on, the global population size continues its rise. For example, in the data it can be seen that the global population went from .68 billion individuals in 1700, to a predicted 9.46 billion by 2100. Also, the life expectancy increased from 27 years in 1700, to a predicted 81 years by 2100. (Ronald Lee,

While it may be observed that the exponential rate of growth is slowing, the world population is still growing rapidly. Perhaps the biggest concern is not the actual population increase but the distribution of the growth (Wilson, Population).

The human population is growing rapidly, and Earth doesn't have enough space for it. In 1967, Earth had a population of 3 billion, and only about 50 years later, that number had doubled into 7 billion. There are many reasons why our population is increasing so fast, in so little time, but I'll only go over two. The first, and foremost the most recognised reason, is the birth to death rate ratio. Every minute there is almost twice as many births then there are deaths; 200 births to 100 deaths. There is an estimated 350,000 born every day with only 150,000 deaths, making there 4 births every second and 2 deaths every second. Overwhelming right? Well the second reason which goes hand in hand with the birth to death rate, is, over the last few hundred years, we have become more intelligent, and more self aware. Our knowledge on medicine has grown like no other, and our life expectancy has grown with it. With many more factors modifying our population rate, these two show it best. We are living longer and having more babies, but soon we’ll need to stop.

As time goes by, the human population increase every year. This also means an increase

According to the lecture, “If the birth rate is higher than the death rate, then population growth will be exponential.” What sets us apart from history is the fact that our death rate has greatly decreased due to our ability to fight leading causes of death. In historic times, the average projected age of survival was far lower than it is now due to the lack of knowledge on how to deal with and prevent different diseases. As time passed, humans began to learn more about medicine and treating sicknesses, but this was a slow and steady process. Plagues like the Black Plague during the 1300s killed off millions of people in Eurasia, preventing the population from growing exponentially. Couple with war and crime that was at its peak during the 1940s, the population did not have room to grow up. But as time continued, the rate of war and crime decreased, leading to one less reason of death to worry about. Famine was also a huge cause of death during 1870 but begins to decrease in 2010. The combination of the decrease in causes of death that stems from the better technology to deal with diseases, less wide-scale wars, less famine, and the continuous birth of new live caused the population to seem rapidly grow from around the 1950s onwards (this makes sense as it was right around the end of WWII, the last major war to affect the entire world). The migration of people and intermixing

The expansion and development in all of the earth’s climate zones and habitats, as well as modern agriculture’s ability to grow more food for each unit of farmed land, play an important role in the population growth. Socioeconomic factors such as, healthcare, culture, family structure, marriage and social status also influences population growth, are contributors to population size increases through birth rate, as well as, decreases through the death rate. This imbalance of population equilibrium is a result of improved sanitation and health care, and the development of antibiotics and vaccines for the control of infectious diseases ultimately resulting in population death rates dropping.

billion in 1900 to over 6 billion in the year 2000 (Haugen, sec.2). This expediential population
