Effects Of Exponential Population Growth

Over the past years, there has been an exceptionally large national increase which has caused several population issues. These issues include: homelessness, deforestation and more fields being used to make space for shops and houses disrupting the biodiversity growth. Problems like this are caused when there is an abnormal increase in the birth rate where more babies are born; this is also known as a ‘baby boom’. This can occur when nations have more children as a whole and events like this normally takes place after an achievement – an example being when we won the World War Two. The country was relieved that the fighting was over so their instantly celebrated which is why more children were born. In the last 50 years alone, the population has doubled showing just how fast the population is actually growing and even though it may seem fortunate that there are less recorded deaths, this makes the Economical

The human population is growing at an exponential rate. It is expected that the human population is going to increase to 9.6 billion by 2050, compared to 7.2 billion in 2013 (Porter). Because of the increasing human population, the rate of food production increases causing food waste produced to rise as well. Food consumption has decreased to less than a quarter of what was consumed in 1961 for people living in developing countries (Porter). These statistics are important to highlight because according to the United States Environmental Protection Agency, most landfills are made up of food waste which is causing the emissions of greenhouse gasses. The Environmental Protection Agency also states that cows produce one of the most dangerous greenhouse gas known as methane. Methane is 21 more times stronger than carbon dioxide. The reason why this needs consideration is because beef is the most consumed meat compared to other meats such as chicken, which has less greenhouse gas emissions. Countries with the most greenhouse gas emissions come from great financial economies in which citizens are privileged with what they eat. The increasing rate of releasing emissions by food waste can be dramatically slowed down by, using systems that convert food waste into a source of renewable energy, implementing policies that limit the amount of food waste in each country, and having governmental officials influence citizens to take into consideration the amount of food waste they produce.

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?

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.

The Global human population increases growth amounts to around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012. It is expected to keep growing, and estimates have put the total population at 8.4 billion by mid-2030, and 9.6 billion by mid-2050. Many nations with rapid population growth have low standards of living, whereas many nations with low rates of population growth have high standards of living.

The human population has been growing rapidly for centuries. What is happening and, most important, what will happen to all of us and our planet if this continues? One of the most important properties of living things is that their abundances change over time and space. This is as true for our own species as it is for all others, including those that directly or indirectly affect our lives. for example, when providing our food, or materials for our shelter, or causing diseases and other problems. It is safe to say that human populations, like that of the United States, grow at an exponential rate, which means that the annual growth rate is a constant percentage of the population. The danger that the human population poses to the environment

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).

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

In this lesson, we are going to discover why populations do not continue to grow at unlimited rates, and what ecological factors limit population growth. We'll also discover how humans factor into population limits.

You would expect to see a species growing at an exponential rate when a population has a constant birth rate through a period of time and it is never limited by food, disease, or space. WIth an exponential growth the rate of birth of a species alone can control how fast, and in some cases how slow, the population grows. A population will increase its rate and reach its maximum potential if it is filled with limitless amounts of resources. The numbers would start of slowly then pick up as quickly as the new individuals are added to the reproductive pool. Once they enter the pool the rate of growth will continue to increase over time.

a) At the current world population growth rate, I believe there won 't be sufficient resource to help support this rate due to limited resources such as water, farming area, housing, etc with our current technology. However, I do believe that after a breakthrough in technology, there would be more population growth in the world, but would slowly come to a point where it simply can’t sustain any more and this cycle would go on until technology stops advancing. It is difficult to maintain this at a constant rate without decreases at any point with the expanding number of people while Earth has only finite resources. Theoretically though, if we were to able to constantly increase efficiency with our land space, and colonize other planets, the population of the human species would always increase.

Exponential population growth means in the population at a constant rate over a unit of time. It is called exponential growth because the population is multiplied in geometrical ratio. The last 100 years have seen a massive increase in the population, due to medical advances, lower mortality rates, and an increase in agricultural productivity.

For quite some time, the world has experienced exponential growth in a number of areas. Population, industrialization, the world economy, and human consumption of resources all are growing exponentially. When any quantity is growing at a rate of, for example, 10% per year, it takes 7 years for the quantity to double. From 1930 to 2000, the money value of world industrial output grew by a factor of 14—an average doubling time of 19 years (Meadows, "A Synopsis: Limits to Growth: The 30-Year Update”). Had the population stayed constant, the material standard of living would have increased by the same factor, however due to population increases, the per capita output increased by only a factor of 5 over the same period.

Population growth has become a controversial topic for most countries in recent decades. According to some data from parliament of Australia, the majority of Australians would appear to prefer a lower immigration intake than prevails at present. Advocates of population growth consider that increasing population is positive to a country. R.A.(2010) states that we would see rising real incomes as slower population growth leads to slower growth in consumer prices,but that is obviously not inflationary. On the contrast, opponents of population growth evidence that increasing population may result in some social issues. This essay will argue that there are some large negative impacts on a country due to a large population growth, including environmental sustainability, living standards and economic stress.
