Introduction
The biogeochemical cycles of carbon simply refers to the biological, geological and chemical processes that release and absorb carbon and carbon’s movement through our environment. The natural cycle of carbon is governed by environmental conditions and simultaneously governs the environment.
Human alteration of the terrain and ecosystem to serve agricultural, industrial, housing, transportation and other purposes affects the way that soils, sediments, seas, plants and animals undergo the processes that regulate the relative prevalence of carbon in different states and compounds. Aside from disturbing natural processes that balance the distribution of carbon, human activity releases carbon—particularly as CO2 gas—in the atmosphere

My red meat intake is already limited by my budget, but I would struggle to keep it out of my diet if it were more accessible. Dairy, however, is a significant part of my daily diet. It can be cost effective and beneficial to replace dairy milk with a soy or cashew milk. These often have less calories and greater nutritional value than the nonfat dairy that most of us ingest. These two groups contribute one third of the US’s food-based carbon emissions, according to The Nature Conservancy, making it well-worth revisiting your meal plan. Making a point of trading chicken for beef in your own kitchen is a good choice when you’re making dinner for two, but I frequently cook for groups. Making the change can make my get-togethers a little more environmentally conscious—and more affordable for me and my environment.
Conclusion
The carbon cycle will never return to its pre-industrialization state, but the intensifying effects of carbon emission can be halted and even reversed through long-term reduction of carbon-releasing activities. Regulations on industrial practices that put off carbons are a large and significant step, but facilitating change on the individual and/or household level can be exceptionally impactful.
Seemingly insignificant lifestyle changes can seriously reduce our individual contribution to carbon levels in our atmosphere and in our oceans. These changes can be fiscally wise and even have a significant and immediate positive impact on human
Pollution is a major problem for all of us. People need to recognize this situation so we can start making a difference to this problem. In order to start making a difference, the federal government should increase gasoline tax by one dollar a gallon. Fifty percent of this dollar will go towards public transportation, since passenger cars and trucks are a major contribution towards air pollution, according to the United States Environmental Protection Agency, E.P.A (10/4, http://www.epa.gov/autoemissions/emsns.html). Due to the expected increase after this is put forth, the remaining fifty percent of the dollar will go towards safety on these transits. When public transportation increases, air pollution will decrease, which will lessen the harmful health risks towards the environment.
...s per gallon. Carpooling also saves fuel not to mention your wallet. If you have empty seats in your vehicle, carpool with co-workers and alternate who drives and who pays for gas.
Carbon dioxide disturbs ecosystems candidly, both positively and negatively. On land it increases growth in various trees and plants, an influence occasionally called ‘CO2 fertilisation’. Absorption of CO2 into the oceans triggers ‘ocean acidification’, obstructing shell formation by organisms like corals and affecting coral deterioration or
For example, rail modes of transportation may be used to transport large amounts of freight long distance if the railheads are available at both origin and destination. This eliminated the use of semi-truck that create the same amount of emission as one train. One trains can move over 100 containers, while one semi-truck maybe only can move two or three at the most. The environmental effected mode in this situation is train of course. One of most environmental impacted modes of intermodal transportation is over the road truck. The industry aims to reducing emission from the surface mode of truck by increasing the use of alternative fuels and use of less pollutions modes such as carpooling and route sharing. Today’s consumers is having a hard time avoiding products manufactured and transported overseas, as economic globalization moves more goods from factories to major markets throughout the world (Corbett, Winebrake J. 2007). The push by the consumer for goods coming from location has a great effect on emission and global warming. The consumer may not even understand the impact they personally have on the world
Generational conflicts, political strife, environmental regulations, stakeholders in big oil, and many more hurdles affect the push to fully sustainable economies around the world and even here in America. In a world where coal, oil, and natural gas are limited, countries are gobbling it all up as fast as they can before other poorer countries come on the grid. Even though America and other countries gobble up these resources the life of the people is still a struggle to meet basic needs. Sustainability is an intermingling of resource use and protection of the “quality of life”, it is met by using resources sparingly and by recycling or reducing the use of other non-renewable resources to provide for our immediate need, but also to conserve and protect the needs of the next generation and to improve the quality of all the lives to come.
When people burn fossil fuels to accumulate and produce energy a substance called carbon is produced. Carbon is released into the air in a form known as carbon dioxide. Carbon moves throughout the biosphere on the planet as it is recycled and reused. Carbon exists in the earth’s atmosphere in two common forms which are methane and carbon monoxide. These gases absorb and retain heat in a process known as the greenhouse effect. The Planets natural greenhouse effect makes life possible by regulating our temperature. It turns out that adding too much to the greenhouse effect can have horrible consequences on the environment. Each year, five and a half billion tons of carbon is released by burning fossil fuels and of that three billion tons enters the atmosphere. The remaining carbon usually gets absorbed by the oceans.
The world in which we live in at the moment has become poisonous. It has been poisoned by the human species’ daily survival activities. Humans around the world have taken for granted the daily impact that we have on the natural world. It all boil down to each and every breath that we take. Each and every breath that we exhale releases poisonous chemicals into the atmosphere. Until when our existence becomes absent, the world will remain poisoned.
However, the overall observations would remain accurate. Although the Sedan car must travel 120hrs and 21mins (refer to Table 1), it has the lowest fuel cost, fuel consumption, CO2 emissions and requires the least number of trees to offset emissions. Therefore, out of the vehicles analyzed, the car would least harm the environment for a Halifax to Vancouver trip. Through conclusions made, people can make better decisions that will reduce CO2 emissions and harmful effects to the earth to prevent serious consequences and keep the earth safe for future generations, plant life and
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
Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.
The most destructive human contribution to climate change is fossil fuels combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbons levels in the atmosphere cause an imbalance in the earth’s energy. This is because the gases alter solar radiation and thermal radiation which regulate the earth’s energy. Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57 % of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver,
Humans and animals breathe out Carbon Dioxide, often referred to as the greenhouse gas, as a waste product. Plants take in this CO2 and use it to make food. This is called photosynthesis. During this process oxygen is released which is then breathed in by humans and animals. This procedure is repeated over and over and a natural balance is obtained. However this natural balance is disrupted by human activity. People of the world are putting more than 5.5 billion tons of CO2 into the atmosphere every year. 75% of this is caused from the burning of fossil fuels. These fuels are burnt all the time to run factories, power plants and vehicles. The main sources of CO2 emissions are electric utilities, residential buildings, industry and transportation. The other 25% is induced by the destruction of the world's forests. The reason for this is that there are less trees and plants to take in the CO2 but there is just as many, if not more, humans and animals to breathe it out.

Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. The greenhouse gases are carbon dioxide, methane, and nitrous oxide. “Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, and wood are burned.” (2) The gases help to warm the surface of the Earth. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperature of the earth would be considerably cooler. “Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability.” (3)
Today talking about environmental issues lately to be like a common topic discussion until people take it for granted. However, the world facing a complex environmental problems related to each trouble that connected to one another and come out with greater impacts to the environment and humans. This is because the effects of environmental only can be seen in long term period rather than immediately result show up. Environmental issues must become one of the controversial matters in the society in order to make people know the truth what the world currently facing. There were a lot of environmental disaster happened such as climate change, global warming, various of pollutions, earthquake and etc. the rise of environmental issues begin with this urban development occur through several countries following with the technologies equip along. For sure, development will cause a huge negative impact to the environment if it deals without a care. Besides, the environment is the place in the ecosystem to hold and use in finding resources to continuously survive in this world. Thus, the finding and digging for the resources which happening extensively without preservation will not restore the surrounding similar with before. But then, the change cannot be refuse and people need to take an action to save the threaten the world and the ecosystem from being extinct. If each country has own output in causing an environmental problem, then consider the world to hold all the damage occurred. Exposing the effects of environmental issues throughout the world, make people realize the important to take care the environment.
