Carbon dioxide is the most common greenhouse gas contributing to climate change. Scientists have seen a measurable increase in the amount of carbon dioxide in the atmosphere in recent decades. There is considerable consensus within the scientific community that this increase is due largely to human activity. Actions such as driving long distances to work, taking frequent flights, and living in a large home can lead to large amounts of carbon dioxide emissions. One way of measuring these emissions is through carbon footprints. A carbon footprint is an individual’s aggregate carbon emissions across various aspects of their life. Once an individual can see quantitatively the size of their carbon footprint, and compare these results to peer, national, …show more content…
Rather than living in a northeastern exurban setting, I plan to live in a city in a warm climate. I plan to live in an apartment much smaller than my current house, which should reduce the amount of electricity and heating oil I use. Additionally, living in a city will allow me to rely more heavily on public transportation, perhaps so much so that I would not need to own a car. I would like to live in a bike friendly city that would further reduce my carbon outputs. One figure that remained the same, rather than declining, was flights. I still expect to travel frequently in the future, but hopefully the cut downs in other aspects of my life will make this carbon indulgence less egregious. Compared to national averages, my current carbon footprint is quite large. In fact, based on the data from 2014, it is 15.8 metric tons more than the national average(Europa). When the scope is widened to include the whole world, my current emissions seem even worse. The world average is 4.936, which is significantly less than my 32.30 metric tons of emissions (Europa). However, if I adjust my habits and lifestyle as I hope to in the next five years, my emissions will be below the national average and only slightly above the world
One starting point to reducing the amount of greenhouse gases that you release is to find your carbon footprint. The carbon
Pollan even agrees that becoming friendlier to the environment may seem like a bit too much. Scientists may even show that it could even be too late to save the planet from the climate change. One NASA climate scientist, James Hansen, began warning about global warming 20 years ago. According to Hansen, the amount of carbon we are emitting is going to change the world as we know it. Scientists have seen the climate change affect the world on a grander scale as of today and we are seeing ice caps melt at both poles. The sunlight that used to reflect off of the ice back into space is now being absorbed into the soil and creating a warmer environment. This is causing global warming to occur faster than most scientists predicted. There are ways to possibly slow down the carbon footprint each person is leaving on the world. By growing a garden and even making some of your own food can lessen the carbon footprint each person
Canada; known for peacekeeping, multiculturalism and having one the largest ecological footprints in the world. What is an ecological footprint? The ecological footprint is a measurement of the amount of greenhouse gases produced by the activities in a person's daily life. One main source of greenhouse gas is burning fossil fuels. That includes the gas in a person's car and the coal burned at the power plant. Scientists have concluded that humans are producing more greenhouse gases than ever before. These gases trap heat in our atmosphere, causing our planet to warm up and changing our climate. The ecological footprint, therefore, measures the amount of potential impact a person's daily life has on the environment. By reducing the amount of greenhouse gases produced by people's lifestyle, they can reduce the footprint and help slow climate change on Earth. Canadian's are starting to get accustomed to using a surplus amount of energy when it is never needed and throwing garbage on the ground because the trash can is too far away for them reach. Canadian's are also using up the little natural resources left on this planet for sustainability. Crops, oil, trees are being used so much, that there might not be enough for the future generations. Canada must realize that this is a situation that must be taken seriously and that must be executed properly by meeting the social, environmental and economical standpoints. To reduce the ecological footprint and to regain sustainability, there are many things Canadian's can do to change the current situation. Ecological footprints can be reduced by using alternative energy sources, reducing energy consumption and by using cleaner transport to reach destinations.
The entire world contributes to the carbon emissions but there are ways we can use less gases to help decrease the amount we use. One way is carpooling. Carpooling can help decrease the amount of carbon emissions we make by having less cars on the road to make carbon emissions. Carpooling also saves you money. Other ways are using alternative fuel sources. Some alternative fuel sources are biodiesel, ethanol, hydrogen etc. There are also cars that use other things like electricity or less fuel. These can be cheaper than just petroleum and less harmful to the environment. “HEVs [hybrid electric vehicle] typically achieve better fuel economy and have lower fuel costs than similar conventional vehicles. For example, the 2016 Honda Civic Hybrid has an EPA combined city-and-highway fuel economy estimate of 45 miles per gallon, while the estimate for the conventional 2015 Civic (four cylinder, automatic) is 35 miles per gallon” afdc. In this day and age we are getting better at carbon emissions and fuel usage but we have a long way to go to achieve almost no carbon emissions, if that will ever
In conclusion, it is critical to understand that current human activities are accelerating climate change and that the future human activities will affect their trajectories. Because fossil fuel based energy source produce a lot of heat trapping pollution, small changes to our daily activities will reduce human contribution and human behaviour. With these small changes children will be at risk to the exposure of atmospheric carbon dioxide produced by the use of fossil fuels.
There is no hesitation when it comes to whether humans impact the global environment. However, it is questioned in whether human’s ecological footprint is either negatively or positively impacting. In clear perspective, humans share from both sides and their ecological footprint is noted towards whether it will benefit or harm the environment around them. Topics such as overpopulation, pollution, biomagnification, and deforestation are all human impacted and can harm the environment, but some include benefits into helping the world around us with solutions to their problems.
Carbon footprint can be defined as the amount of greenhouse gases an individual produces at a time through diverse activities. A person’s carbon footprint is the sum of all emissions of carbon dioxide (CO2), which were induced by an individual’s daily activities for a given time frame. CO2 is one of the many greenhouse gases that are responsible for causing global warming which we are currently experiencing today. Carbon footprint is an extremely powerful tool which we can utilize to understand the impact that our personal activities have on global warming.
Carbon dioxide or CO2 is known to be one of a number of gases that are astonishingly transparent to the visible light that falls on the Earth from the Sun, but it absorb the infra-red radiation that emitted by the warm surface of our Earth, to prevents its loss into space. Moreover, CO2 has varied considerably and this affected the Earth’s temperature. Most common source of this CO2 is known as the fossil fuel. Fossil fuels are primarily coal, hydrocarbons, natural gas, or fuel oil that formed from the remains of the dead plants and also animals. The burning fossil fuel that has been created by humans is the largest source of emissions of the carbon dioxide.
One of the most compelling and difficult environmental problems society faces today is climate change. People do not realize how much the environment has changed for the worse in the last ten years, until they are told that the last two decades of the 20th century have been the hottest in the last 400 years, according to climate studies (Conserve Energy Future). Today, the carbon dioxide levels have reached 396.81 parts per million (ppm). “Carbon dioxide (CO2) has also increased over the last 100 years-- from about 300 ppm to 370 ppm. Interestingly, the majority of these additions have occurred in the last 50 years, when temperature increases have been the slowest” (geocraft).
Every day the world around us is changing ever so slightly in many different ways. Humans can affect the environment through our day to day lifestyle without even noticing the change. An ecological footprint is a measurement of how much a person uses the environment around them to live their life. This given measurement can help one to see their impact on the earth. It is an important tool to understand what actually a human does to change the habitat near them. My ecological footprint results gave me a perspective of how my daily life can impact the world I live in, as well as, how I as an individual can change my actions to make less waste on earth. It is also useful for each person to know their own ecological footprint since no one live

The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.
In their view of the future these individual Ecological Footprints will be tracked as closely as the stock market, ensuring that buildings, products and cities are projected to have a one-planet Footprint, and where humans take care to live within the renewing means of our planet. T...
My ecological footprint is 4.4 Earths to provide enough resources for the population. It would use 19.4 global acres to support resource productivity. It would produce 19.6 tons of carbon dioxide.
Human activities add to the levels of these gasses, causing more problems. “Automobiles, heat from homes and businesses, and factories are responsible for about 80% of today's carbon dioxide emissions, 25% of methane emissions, and 20% of the nitrous oxide emissions.” (3) The increase in agriculture, deforestation, landfills, industrial production, and mining contribute a significant share of emissions also. These gases that are released into the atmosphere are tracked by emission inventories. An emission inventory counts the amount of air pollutants discharged into the atmosphere. These inventories are important in studying the affects of global warming on the Earth.
