The Effects Of Carbon Dioxide Environmental Sciences Essay

The Effects Of Carbon Dioxide Environmental Sciences Essay Carbon dioxide is a simple mixture of exactly what it sounds like; one part carbon with two oxygen atoms attached to it. Carbon dioxide is in a gaseous state at normal temperatures and its chemical equation is stated as CO2. The gas originates from many different sources around the globe. Some of the most common and highest producers of CO2 are: fossil fuel combustion, iron and steel production, natural gas refinery systems, and the manufacturing of cement. The burning of fossil fuels is the largest single producer of CO2 gas. Many people associate this with the internal combustion engine which powers the modern automobile. In fact, the largest producer of carbon dioxide, in the United States, within the fossil fuel combustion group is the generation of electricity (EPA). Transportation comes in second place in the United States for CO2 production levels. This includes the burning of gasoline, diesel fuel, and many other petroleum based fuels. Although the burning of fossil fuels hap pens to be the largest source of CO2 there are also natural causes of the gas within the atmosphere. The breathing of animals, volcanic eruptions, and release of CO2 from the ocean, which happens to be a large carbon sink (meaning that it stores mass amounts of carbon), are all natural causes of carbon dioxide. One of the great parts about our Earth is the natural way it can clean itself. Carbon dioxide is a naturally occurring gas within our atmosphere. Due to this naturally occurring substance there is a natural way for decreasing the levels of CO2. The processes that absorb and consume carbon dioxide consist of the natural photosynthesis process in which plants/trees use the suns energy and convert it into food. During this process carbon dioxide is drawn in through the leaves and stored within the main mass of the plant/tree. The carbon is then drawn into the soil through the roots of the agricultural crop or tree. This is natures way of drawing the carbon dioxide out of the air and into the ground where it can be stored. Although the plants have temporarily removed the CO2 from the atmosphere the substance still exists and can be re-released into the atmosphere through a tilling process of the ground or digging up the soil. Even though the carbon dioxide is being released into the air again this is how nature self regulates the CO2 on its own. With naturally occurring carbon dioxide levels this process works great. However, it cant completely compensate for human generated carbon dioxide levels which are produced today. The CO2 emissions today are higher than natural amounts due to the burning of fossil fuels as previously mentioned. These increased emissions due to fossil fuels burning can be reduced and battled in order to try and keep the CO2 levels at a manageable amount instead of becoming out of control as the current trend is currently working toward. Technology will help us to develop machines and devices to reduce the emission of carbon dioxide from the burning of fossil fuels. However, currently we do not have the technology to completely eliminate the gas from our emission list. In order to reduce CO2 emission levels action must be taken to enhance a device in the exhaust of modern machinery. New technologies could also be introduced to various other parts of the combustion process in order to make it more efficient. The more efficient a combustion process is, less fuel will be needed and therefore less CO2 will be produced from that running engine. A great way of reducing the carbon diox ide levels would be to switch over to a different type of fuel energy in order to receive the same amount of work time, or more, with less maintenance. One method of reducing CO2 levels is to use Carbon sequestration. This process involves capturing the exiting carbon dioxide and storing it underwater or underground in order to reduce the CO2 levels in the air. It is a very costly process but it is an option available for reduction of carbon dioxide (Zactruba). The industrial revolution was a major improvement for the world. During this time there werent any regulations on carbon dioxide levels emitted from production plants. Therefore plants back then were producing large amounts of CO2 and nobody thought anything of it until testing was done at a later date. Cars built during this time period were not fitted with emissions sensors and parts due to the lack of requirements for the emissions gasses and the lack of technology during the time. Levels of various different gasses are tested every so often and in 2005 the CO2 levels were tested and the results showed an increase of 35% over the levels tested before the industrial revolution hit. This proves that the industrial revolution along with current fossil fuel burning has produced mass quantities of CO2 and placed the gas into the atmosphere (EPA). The increase in carbon dioxide in our atmosphere is said to have been a contributing factor to the global warming effect. CO2 is named a greenhouse gas along with other gases such as methane and nitrous oxide. These retain heat and emit it at the same time. This causes a long term warming effect with increases in concentrations of the gases. Major increases in the amount of carbon dioxide will lead to this heating effect. With no mass effective way to decrease the amount of CO2 in the air it will be hard to reverse this effect unless a different form of combustion and transportation is developed. With new and emerging technologies it can seem feasible to create a device or vehicle that doesnt emit carbon dioxide through the exhaust of the vehicle or the process of creating the fuel needed to move the vehicle. This technology sounds amazing and revolutionizing. However, it has not yet been fully developed and no promises have been made toward it either.

Good or Evil :: essays research papers

Good or Evil? The topic of this journal, is one that has caused much debate for a long time. Are we inherently good or evil at birth, or are we nurtured to be so? Many people believe that we have a natural tendency to be evil. Others think we are born good. To make thing a little bit clearer, I will give my definitions of what â€Å"good† and â€Å"evil† mean in this journal. â€Å"Good† as explained later, means â€Å"obeys rules and ethics of society over several centuries†. â€Å"Evil† means, â€Å"deliberate, or ignorant actions against rules of society†. Personally, I think that we are born impartial to either side, and it is our experiences, and the things that are impressed on us as we grow up. If a person were to grow up with no influences, then they would be pulled to what we see as evil, such as smashing a little RC car because it almost tripped them, which, if we didn’t know it was wrong, we would probably do so also. Another example toward my theory is that if you made two clones, and sent them down two paths, one to a rich family, and the other to a lower class family, at birth these two people are the same, and at death, they are entirely different. They could have been exactly the same, however, because of their upbringing, and experiences, they are entirely different people. An example not unlike my previous one would be my sister and I. We are twins, yet our interests are different, because we have perceived events differently, and we have had different influences in our lives. Even though she is a girl, and I am boy, I still believe if we had had the same experiences each other had, we would balance out to have relatively the same personality. Some people add to the theory I believe in. They say that what I say is true, however, they think that certain things are wired into the brain during creation, so two clones could be the same, (They both are genetically programmed to love a type of animal) but one likes dogs, and the other flying squirrels.

Black People and James Baldwin

Deborah Lee Period 1 May 28,2012 Supplemental Reading Assignment A. The theme of Baldwin’s essay is equality. He establishes this theme in his essay with the juxtaposition of a poor white man and a black man. In this essay, Baldwin speaks of how â€Å"People are continually pointing out to me the wretchedness of white people in order to console me for the wretchedness of blacks. He says that people say that being black is not that bad because there are white people in the same situation and that there is still hope for the black because of people like Frank Sinatra and Sammy Davis but it is still not something â€Å"to be regarded with complacency† because the situations of Frank Sinatra and Sammy Davis are just rare. Equality in America at the time was possible with â€Å"determined will,† but still very rare. Another way James Baldwin established the theme of equality in this essay was when he mentioned the projects, more specifically, Riverton.Baldwin establi shes this theme of equality through mentioning Riverton for Riverton was a physical representation of the inequality of blacks and whites in America back then. Baldwin said, â€Å"The people in Harlem know they are living there because white people do not think they are good enough to live anywhere else. † There was going to be no equality if people were told to live in certain places because of their color. Baldwin also makes this theme extremely clear when he says, â€Å"Negroes want to be treated like men. † B.The tone of the essay, Fifth Avenue, Uptown: A letter from Harlem by James Baldwin and the tone of the poem, Theme for English B by Langston Hughes are similar. They are similar for both authors show that there is hope for equality through the tone of each text. In the poem, Theme for English B, Hughes says â€Å"You are white — / yet a part of me, as I am a part of you. / That’s American. † Hughes expresses that although he may be the onl y black person in his class, he is still American like the rest of the class and should be considered equal.The tone of the essay and poem is different from the poem Incident by Countee Collen. This poem’s tone is complete opposite from the other poem and essay for Collen uses more of a doubtful tone. This poem is more about just being sad and bothered that blacks and whites are not equal instead of being hopeful for the equality of the two races that is soon to come like the other poem and essay. C. The perspectives on race in these texts are different than in To Kill a Mockingbird for in To Kill a Mockingbird, Atticus believes that there is good and bad in everyone and that nobody should be hated or claimed as all bad.In the book, Scout asks Atticus if it is okay to hate Hitler but Atticus says that you shouldn’t hate anybody, no matter how bad they are because there is a good side to them. This shows that Atticus’ perspective on race is different from the aut hors of the poems and essay for the authors believe that the whites are bad people because blacks and whites are not equal. While Atticus is just like the authors for he wants equality between black and whites, his perspective is different for he believes that this equality will be brought once the good side comes out of the white people.

As the company continues to use the machine over their five year period the net cash flow increases up to over one million dollars. The positive values of cash flow over each year implies that there is good potential for profit to be made from the investment in the new machine. The terminal cash flow will indicate the actual value of the machine after five years. This is important when it comes to the resale of the machine. The book value of the machine after five years is twenty five thousand dollars and the actual value is about nine thousand four hundred eighty nine dollars. There is a huge difference in the book value and the actual value. This will need to be considered when determining whether or not this is a good investment depending on the importance of the return on investment from the resale of the machine.
