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
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
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
One starting point to reducing the amount of greenhouse gases that you release is to find your carbon footprint. The carbon
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.
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).
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.
A human’s every day life consists of using and consuming resources that produce waste. Seeing an increase in population, means seeing an increase in waste. In order for future generations to be living in as little pollution as possible, it is important for current generations to under stand the impact they are having on the environment. An ecological footprint is a good tool to calculate this; it measures supply and demand. It measures the area of biologically productive land and water required to produce the goods consumed and to assimilate the waste generated in one year. In simpler terms, it is the amount of environment necessary to cancel out the production of goods and services necessary to support the lifestyle you live. I believe that

Although it is hard to completely erase the damage and negative effects of global climate change, it is never too late to start improving our everyday lives to help benefit the planet we live on. Small changes like a light bulb, installing solar panels on a house, or even recycling a bottle of coke can help reduce the size of individual carbon footprints. It is also beneficial if one has enough money to indulge in an electric car. Perhaps in the future electric cars and biofuels will be the only options for driving creating a healthier planet to live on. In the future, electric cars and solar panels should become more affordable for the average person to purchase since they are currently too pricey.
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.

The way I live compared to a few classmates of mine, I have the most impact on the earth. As well as compared to my whole class I would say that I change the environment more than an average person would. For example my total footprint according to the ecological footprint quiz I took is about 28 acres. With the results that it had given me I suspect that my actions of using a lot of services and the way I use my transportation, are the most impactful way I affect the earth. The reason my mobility on the quiz is one of the highest percentages from the categories is because I drive a good amount, and on top of that I have truck that does not get good gas mileage which in results give off more emissions to pollute the air. I was not surprised with my ecological footprint because I knew I impacted my environment greatly, but did not know the exact or estimated amount. In comparison to my classmates I also was not surprised that we all affected the earth greater than an average person because I knew that I did, so it led me to think that there were people who in similar amount affect the
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.
