Global Warming

...GS1140.U2.HO4 Richie Lowther (20289041) The Connection between Global Warming and the Hole in the Ozone Global Warming and the Hole in the Ozone are two topics that are highly debated in the science community. After researching both phenomena I feel that yes, both are somewhat closely related, but I don’t feel one is the main cause. As far as the two producing the same effect, I believe they are somewhat creditable. The Hole in the ozone is caused mainly by CFC’s (chlorofluorocarbons) which is mainly found in aerosol spray cans and other man made pollutants. The two chemicals in CFC’s that are the worst to the ozone are chlorine and bromine and are to be considered potent to greenhouse gases. The two chemicals are not found in the higher atmosphere and not considered the main cause of the hole in the ozone. The ozone hole permits more ultra violet radiation to reach the earth’s surface and in turn could cause more radiation to be reflected. Global warming is caused by the increase of the atmospheric concentration of gases that trap the infrared radiation close to the earth’s surface, mainly carbon dioxide (CO2), methane (CH4), and water vapor. Although CFC (the molecules that destroy ozone) and ozone its self are greenhouse gases, their concentration in the troposphere (the lower layer) where we live is normally low. In my conclusion between the connection of both phenomena, the problems and risks of the greenhouse effect relates to human influenced climate......

CFC manufactures stoneware and fine china tableware which contributes part of tableware product line under Claytan Group. The company intends to invest in China as part of its international expansion project. The cultural distance between Malaysia and China is small. Based on Hofstede’s Value Dimensions Framework, China has almost similar cultural dimension compared with Malaysia. Malaysia is a collectivism society whose give priority to the goals of the group than personal goals. Besides that, there is high power distance between society members. Cultures that are relatively collectivistic generally have higher power distance. Both Malaysia and China has weak uncertainty avoidance. Collectivistic felt that uncertainty is a normal feature of life and each day is accepted as it comes. CFC will expand the production plant to China as a wholly owned subsidiary under the CLAYTAN Group due to cost-reduction motive. The implementation of minimum wage rate system in Malaysia, lower transportation cost, and the form of China-ASEAN Free Trade Area (CAFTA) induce the company to expand its production plant to China. China and Malaysia categorized under high context communication style. However, certain degree of adoption is still needed. In term of negotiation, collectivism society such as China and Malaysia are more concern about in-group. The high power...

...way we are finding out how the ozone is depleting is through many observations of computer models and of the atmosphere. We can also introduce chemicals and other substance reactions in a laboratory environment to study what it does to an atmospherically setup like the earths. Through all of these studies we have found that certain chemicals and there are several in particular that increase the rate of depletion in the ozone but the biggest leader in the depletion of the ozone is Chlorofluorocarbons or CFC's and we will get into that later. An example to show how we are losing the ozone layer in our troposphere is a river. A river usually flows at the same level just as the ozone is moving around but remains at the same level. Once mankind starting introducing these chemicals and other elements into the atmosphere it is lowing the level of ozone before it can be remade again. This is where we are seeing a loss in our ozone and a rise in projects to slow down the emission of CFC's and other things harmful to the ozone. We will now get in depth with the reasons why ozone depletion is happening on earth. The ozone is divided into several different layers that are spread across the troposphere and the stratosphere. The troposphere...

...Garbis Chekerdjian 14/3/11 Mrs.Chalhoub English 5 Paragraph essay The Effect of Global Warming The earth was created 4.5 billion years ago and it survived the ice age, the floods, the earthquakes… Will it survive Global Warming? Global Warming is harmful to planet earth and humans! First, CFC’s destroy the ozone layer and UV and infrared rays will kill humans. Second, air pollution will heat up and all the icebergs are going to melt and cities are going to flood. Finally, a lot of humans and animals are going to die. CFC’s is a kind of gas that comes from deodorant, A.C., fridges, microwaves… When the CFC gases enter the atmosphere, they destroy the ozone layer. And because of that UV and Infrared rays can enter the earth and harm human beings. When a ray touches the human skin the human may get skin cancer or any other disease to the skin. So, we have to stop using microwaves, A.C., fridges and deodorant. Another example of global warming is air pollution. When cars and factories and machines pollute the air, the planet will get warmer because of the gases. When the earth will get warm the icebergs from the poles are going to melt this will affect the golf stream. When the ice will melt all the cities and towns near the sea will flood. And a lot of people are going to die because of the water. And finally a lot of the animals and the humans will die. The animals like the polar bear will disappear because when the......

Harvard Business Case

...and overhead costs at their peak, Dixon is in charge of implementing positive changes in her department. For one of her first moves she appointed Larry Williams as head of the new Overhead Reduction Task Force. This task force is being formed to decrease overhead costs by 20% in the next four months while also increasing sales. External Factors Affecting CFC There are three main external factors that are influencing the overall sales production in this case. First off, one of CFC’s major competitors introduced a new household coffee maker that sold at the same retail price as CFC’s coffee maker, but CFC did not have the same innovation incorporated into their product. Secondly, another main competitor of CFC launched a new and improved microwave oven, which severely hurt Countertop’s sales of the same product. CFC’s product line still has not made a comparable substitute for this newly designed microwave oven. Finally, competitors’ pricing of the kitchen products was 10% lower than CFC’s pricing for the same products. CFC believed that these competitors would eventually have to increase their price to cover their actual product costs (which wasn’t the case in this situation), therefore, they kept their prices constant hoping to regain customers eventually. General Internal Factors Affecting Sales Depreciation There are not only external factors contributing to the overall decline in sales in regards to CFC, but also internal factors that play a key role as well....

Mother Nature

...THE IMPORTANCE OF PROTECTING NATURE Nature is God’s greatest boon to mankind.  Nature is the mother of all creations on our earth.  The air that we breath, the water that we drink, the food that we consume, the furniture that we use, etc. are all gifted by Mother Nature.  If not for nature life on earth would have been unimaginable. The bright sunshine, the beautiful mountains, the showers of rain, the tamed and wild animals, the gems and the jewels, the paper on which we write all are the presents of Nature.  We as humans owe our very existence to Mother Nature but seem to disregard this inimitable fact and do not pay any respect to her instead we indulge in polluting and destroying our environment.  Today, people uproot & trees for furniture but forget to plant a new sapling in its place.  The tragedy of modern day existence is people are enjoying luxury items such as cars, air-conditioners refrigerators, etc. failing to realize that they are polluting the ecological balance of our earth.  Today’s generation seems to have no moral responsibility towards nature. The ecologists, scientists and environment activists all over the world have realized the need for protecting nature and its natural resources.  The major problems that our earth is struggling are with pollution, population, depletion of mineral resources, global warming, extinction of various species of animals and cutting down of forests. Our beautiful earth is turning into a defaced, ugly surface......

...was bullied by burgeoning environmental groups (who were concerned about “how many trees it takes to make paper” ) into switching from paper packaging to Styrofoam containers. These containers are what McDonald’s soon came to call (apparently without irony) “clam shells.” Clam shells were not McDonald’s first choice. But Styrofoam is an exceptionally good insulator and so McDonald’s acquiesced to this environmental strong-arming. Shortly thereafter, near the end of the 1980′s, environmentalists came along again and attacked McDonald’s use of polystyrene (the technical name for Styrofoam), because in order to make polystyrene, chlorofluorocarbons (CFC’s) are required, which chlorofluorocarbons purportedly poke holes in the ozone. So out of the goodness of their hearts, the suppliers of McDonald’s clam shell stopped using CFC’s in their manufacturing process. This wasn’t good enough, however. The clam shell came under fire again, this time for other things: It doesn’t “biodegrade” in landfills, environmental groups said — though, in fact, next to nothing, no matter how “organic,” biodegrades in landfills, because biodegrading requires oxygen, which compressed trash does not have. Another reason they gave: plastic and polystyrene “take up a great deal of space.” (Untrue.) Yet throughout this whole fiasco, McDonald’s was completely compliant. They even embarked upon the suggested polystyrene recycling program. Pressed, however, by the Environmental Defense......

...Consequently, sea levels are expanding, glaciers are melting, cloud forests are desiccating, and nature is scrambling to keep pace of the environmental change (Hansen, 2016). Scientist have discover that mankind have caused the warming of the earth in the previous decades past due to the releasing of heat-trapping emission as we produce energy for today’s way of living. These heating agents are currently changing the normal cycle of climate change that all living creatures and plant life must be dependent on. The carbon dioxide we emit in the atmosphere currently will accurately regulate not only our climate future but also the future for generations to come. The primary objective is to control global warming by restricting the release of CFC’s gases into the atmosphere. We as the...

Entropy describes the chaos that is brought forth when energy transforms. 6. I believe that yes the term carrying capacity can apply to both the ecosystems and human beings. The definition is explained in the book using human population growth. But I also believe that many ecosystems can destroy themselves with over population so in order for them to survive they need a equal “birth” rate and death rate. This carrying capacity would allow an ecosystem to survive. 7. CFC’s are Chlorofluorocarbons. They are used in refrigerators, aerosol, and air conditioning. They have to do with the ozone hole because they are one of the main causes of it. Over the years uses of CFC’s started to grow and with it the hole in our ozone. 8.

Atmospheric Issues

... Brian Taylor Ozone Depletion The atmospheric issues that we are facing are now becoming more of a major problem now more than ever. The biggest major issue I believe we are facing is ozone depletion and it is depleting at an alarming rate. We now have major holes where the ozone molecules have been ripped to shreds by chlorine and bromine. (National Geographic) The biggest ozone hole is over the Antarctic which has been getting bigger since the mid 80’s. The biggest contributor of producing these deadly chemicals, are the industrialists that use aerosol sprays that contain the chemical chlorofluorocarbons (CFC’s). The government has recently within the last 16 years started to face this on- going problem and banned CFC’s from being used. This reduced the percentage rate of the chemical chlorine but experts still say it will take another 50 years for that chemical to balance itself back out. Even so the damage has already been done and the ozone molecules will not heal which means our earth’s protective layer will never be rebuilt. All we can do now is do everything we can to save what protective layer we have left, by reducing the amounts of the chemicals used to kill our ozone layer dramatically. The problems that ozone depletion is causing, is deadly radiation which causes cataracts and skin cancer, which is on the rise as well. It not only hurting humans though, it is also Affecting animals and......

Some air pollutants lead to asthma where chemicals in our bodies make the muscles constrict and effects the skin pores for airways. It makes the airways very small and can cause coughing, wheezing and general breathing problems. Asthma is one of the major diseases in the world. Secondly, skin cancer occurs due to the ultra violet radiation from the sun. The pollutant air is known as chlorofluorocarbons (CFC) do major damaged to our environment. The CFC combines with the earth’s upper atmosphere of ozone layer. The ozone layer protects the earth from the ultra violet radiation of the sun. The CFC’s gas molecules transfer and destroy the ozone layer and cause the skin cancer. So, skin cancer is another disease contributed to air pollution. Thirdly, air pollution also causes acid rain on the environment. Factories, power plants and automobiles release contaminating particles into the atmosphere which is fall to the earth in the form of rain that called acid rain. Acid rain can destroy plants. Flowers and trees. The rain polluted air flows into lakes from which animal drink. Animals and marine life can be destroyed by the acid rain. Buildings are also affected by the acid rain.

Global Warming

...In today’s world, there is a drastically increase in manufacturing industries due to the increased knowledge of mankind. Modernized machinery and equipment and the glory of one mankind to become rich forces him to endeavor in this historical event. Due to the fact that a human is more concerned only by getting the best out of the environment, the environment at the end suffers. Gases that include methane (CH4) and nitrogen oxide (N2O) are emitted into the atmosphere during these industrial processes hence there is the depletion of the ozone layer resulting in the so called ozone hole. Thus the essay below would highlight more on human’s impact on the atmosphere and later effects of the ozone hole which in turn affect them. Albarca J.F (2000) notes that an ozone layer is a belt of ozone gases which is located at about 15 to 50km above the earth surface. This layer blocks harmful ultraviolet (gamma and alpha rays) part of the solar radiation from reaching the earth surface which will in future cause nonmelanoma skin cancer. Ozone depleting substances like chlorofluorocarbons thin this ozone layer resulting in a large area having half or less ozone than normal to appear hence the term ozone hole. Handwerk (2000) elaborate that the ozone is created naturally when oxygen molecules high in the atmosphere get broken by sunlight into two free oxygen atoms. A free atom can then bond with an unbroken oxygen atom and ozone is born. Ozone depletion happens when an ultraviolet light......
