Examining the relationship between population sizes and carbon dioxide emissionsThe world’s population has constantly been increased from 3 billion to 7 billion people in the last few decades.
The planet is predicted to have another 3 billion humans by 2050. This rapid population growth on a global scale will have certain negative implications. This includes limited resources, such as food, water and housing, and also a greater impact of pollution of the planet.At the same time, there has been an increasing concern about increasing levels of carbon dioxide in the atmosphere. Scientists tell us that this comes from humans and their irresponsible actions that is as well causing global warming all around the world. Whether there is a link between population growth and a nation’s carbon emission rates was sparked by the growing issue of global warming, there is a link between atmospheric carbon dioxide levels and climate change indefinitely.This investigation will attempt to discover whether there is any link between a nation’s population and the amount of carbon emissions that it produces yearly. If there is a link, then countries producing larger quantities of carbon dioxide should begin to consider finding methods to reduce the amount that they release into the atmosphere by attempting to cut their emissions on an individual level, thereby reducing their overall emissions.
If this occurs then, over time, slowing the process of global warming might be successful as well.IntroductionThe purpose of this task is to gain perception as to whether a nation’s population has an effect on the yearly amount of carbon emissions produced. Data has already been collected from other sources as secondary research and will be used in this assignment.
In order to make the assessment as accurate as possible, more than one source will be used to obtain data, in order to avoid any biases that the data collector may have had or any inaccuracies that may have appeared in their work.Through finding connections between a country’s carbon dioxide emissions and its population size it can become easier to predict changes that will occur in the environment over the next several years. This is important as environmental damage may be able to be reduced, and more forms of sustainable energy may be introduced if it becomes clear that population growth leads to greater carbon dioxide emissions.The 10 most and the 10 least populated countries have been chosen for this assessment, so it is logical to use the nations that rank as the most and least populous countries as a basis for the rest of the assessment. Overall, through this assessment it will be possible to establish whether the amount of carbon dioxide released by a country is linked to its population, and so find out if the ways to solve the problem of global warming should be linked to reducing the emissions from each individual. Data that will be used in the table of results is a measure of a country’s total carbon emissions, and the calculations shown in the next table are measures of carbon emissions per capita.Research QuestionDoes a country’s population impact on the amount of carbon emissions it produces?HypothesisA country’s population does affect the amount of carbon dioxide that is released, as each person will be using energy that is produced with the release of it.
MethodSelect countries to examine that will make the assessment as wide-ranging as possible. (Use the 10 most populous countries and the 10 least populous countries.)Collect raw data from the countries selected by population size and carbon emissions.
(Use the online sources Gapminder, NationMaster and Index Mundi for reliable data.)Collate this raw data into a table for further analysis. Rank countries in order of population size.Create graphs to display information more clearly (for example, Venn diagrams) as the results will be easier to assess.VariablesIndependent – The population sizes.
Data on this will be obtained from more than one source to make the assessment as accurate as possible.Dependent – The carbon dioxide emissions per year.Controlled – The sampling strategy and the year from which the data has been collected.ResultsPopulation size rankingsCO2 emission rankingsHighestLowestHighestLowestChinaVatican CityChinaAzerbaijanIndiaTokelauUSAColombiaUSAMontserratIndiaNigeriaIndonesiaTuvaluRussiaChileBrazilAnguillaJapanRomaniaPakistanSan MarinoGermanyTurkmenistanNigeriaGibraltarIranPhilippinesBangladeshLiechtensteinSouth KoreaBelgiumRussiaMonacoCanadaArgentinaMexicoSint MaartenSaudi ArabiaKuwaitCalculationsCarbon dioxide emissions per human.DiscussionThis study showed that there is a link between population size and carbon dioxide emissions, but I noticed that the amount of carbon emissions people emit on an individual level were also generally higher among the countries that are more urbanized.
This applies to India and Bangladesh in particular, as they are still in the process of becoming developed countries and so have an increasing rate of urbanization. They are also nations that are responsible for the mass production of certain goods in factories, and therefore also release copious amounts of carbon dioxide. As they are still in the developmental process, laws may be less strict on issues that encourage factories to use environmentally friendly materials in their production processes.Despite population size impacting carbon dioxide emissions greatly, there are other factors that should be considered. The developed countries in the first diagram that have both a large population and are responsible for releasing copious amounts of carbon dioxide into the atmosphere may do so as the people are more likely to have a larger income and so can afford to spend more on things such as petrol, heating and electricity, all of which depend on fossil fuels and can add to the amount of carbon dioxide emissions a person produces.
With the first Venn diagram, there is a combination of developed and developing countries and this is also seen in the second Venn diagram. This can also imply that population is not the only factor impacting carbon dioxide emissions on a national scale. Countries such as Iceland and Greenland have access to hydroelectric power, which does not release carbon dioxide, and so regardless of their population size, the amount of carbon dioxide they emit tends to be very low.However this is not the case in areas such as Andorra or Suriname, whose low level of carbon dioxide emissions may be a result of the high rural populations. Such countries generally have less household use of fossil fuels being burned through electricity, which reduces the level of carbon dioxide emissions overall.
