Global Warming Essay Example for Free

Global calefacient EssayGlobal Warming is an issue that concerns almost e trulybody worldwide it is the primary ca put on for the erratic and sometimes devastating wear that is go through around the world. Global warm is causing the deepen in sea level which in delibe judge make waters the flooding of coastal atomic number 18as and aras with low elevation. Is worldwide warming really happening today? Scientists with the United Nations environmental Program (UNEP) believe it is so (Mank, 2005). It is indisputable that there has been a rise in the concentration of nursery gases (GHG) in the atm during the last century, which scientists think may be one of the causes of global warming. The climate tilt however is not a direct result of the rise in greenhouse gases. Will global warming spell doom for our world? Scientists believe this to be so. Much depends on what actions we take instantly and in the coming years. Meteorologist Jagadish Shukla of the University of Mary land found out that deforestation would cause rainfall in the virago River to decline by more than 26 percent from the current 2. 5 m. to intimately 1. 8 m. a year (Bellamy Gifford, 2000). At the same time, the burning at the stake of fossil fuels, particularly coal and oil, produces sulfur dioxide and nitrogen oxides which atomic number 18 violent to the atmosphere.Findings show that a atomic number 53 smokestack may produce as much as 500 tons of sulfur dioxide a day. When these gases combine with oxygen and moisture, sulfuric sulfurous and nitric acid is formed. The rain leave carry the acids to the ground (acid rain) which may cause the depletion of calcium and magnesium in the tarnish, elements infallible by plants for the validation of chlorophyll and wood, or it may cause the release of aluminum in the soil, which are poisonous and stooge fine-tune the roots of trees (Carwardine, 2000).This study intent to (1) k nowadays the effect of global warming worldwide t hus knowing the global warming and doomsday and (2) widen our knowledge about the ozone slayer and do the humans are the reasons of causing global warming or if its just a inherent process that the earth goes through. II. Literature Review Ozone is an unstable oxygen that occurs naturally in the atmosphere (also called equal region), the upper portion of the atmosphere above 7 miles where clouds are rare.The ozone layer absorbs the dangerous ultraviolet-B (UV-B) rays while it allows the necessitate safe light to pass through. Though easily broken down by other(a) gases in the stratosphere, it is constantly being rep distributeed by the suns rays. However, man is destroying the ozone layer which serves as a defensive umbrella against the suns harmful rays. In fact, the ozone layer is destroyed faster than the suns rays can produce it. It is being destroyed by industrial gases like CFCs (Johnston, 2000). CFCs was discovered by doubting Thomas Widgley Jr., a chemist working at t he Frigidaire Division of General Motors but were discovered hazardous in 1974only after 44 years of use, apply as coolants in refrigerators and air conditioners and spray can propellants in spray cans, medical sterilizers, cleaning solvents for electronic components and raw materials for making plastic foams such as coffee cups. CFCs are estimated to account for 14 percent of global warming. It is dismaying to know that ozone depletion can be found in the south (Antarctica) and north (Greenland) poles (Dolan, 2006).According to British scientist Joe Farman, 40 percent of ozone depletion can be found in the South Pole. At the South Pole is a huge vortex with clouds represent of tiny ice particles, giving chlorine millions of tiny spaces through which it can perform its deadly dance with ozone as yet faster (Simpson, 2000). Both holes at the poles are seasonal, opening and closing each year. In the northerly hemisphere, a more populous region, ozone depletion rate is between thre e percent and seven percent for 17 years, as compared previously to only three percent for100 years.On the other hand, what are the effects of Ultraviolet-B rays to human beings and the ecosystem in general? To humans, they can cause skin cancer and cataract and damage the immune system. To the ecosystem, they can kill planktons (basic element of the ocean food chain), destroy plant heart and crops and change global wind and weather patterns. In 1978, Canada, Sweden, the United States and other countries banned the use of CFCs in aerosols. However, other uses of CFCs were found, effecting an increase in its production. The US still uses one-fourth of the worlds annual supply of CFCs (Turner, 2000).However, in September 1987, 24 nations cooperated for the start-off time to solve this environmental problem and passed the Montreal Protocol. The agreement issued a call for developed nations to givingze the use and production of CFCs while cutting 50 percent of use and production by 1 999. Still, the CFCs currently move up through the troposphere will take seven to 10 years to drift up to the stratosphere. The troposphere is the portion of the atmosphere that is below the stratosphere, extending outward about seven to 10 miles from the earths surface (Bellamy Gifford, 2000). III.Methodology In order to accomplish this study, the researcher used two different methods to make the investigation more informative, accurate, and successful. excursion from gathering information through internet, the researcher gathered information through statistics, charts, and observation. IV. Results and analysis During the earliest times, the life-styles of our ancestors were very simple. The air they breathed was clean. The streams were clear and free of harmful organisms. They used natural fertilizers for their agricultural crops. The surroundings were free of household throwaways.Today, there has been a tremendous growth in science and technology. Such advances have brought ab out changes in terms of new products, improved equipment, and more effective methodologies. Unfortunately, this same technology which made life easier for us produced wastes which are now affecting the quality of our surrounding, air, water, and land. Factories and motor vehicles send tons of pollutants into our air. Excessive air pollution poses a danger to our health and environment. It can likewise cause stunted growth and even death to our plants.Out streams are polluted by discharges from industrial plants that use chemicals. Garbage and sink wastes are carelessly thrown in our surroundings. Synthetic fertilizers and insecticides pollute our land and farm products (Johnston, 2000). At the same time, the burning of fossil fuels, particularly coal and oil, produces sulfur dioxide and nitrogen oxides which are hazardous to the atmosphere. Findings show that a single smokestack may produce as much as 500 tons of sulfur dioxide a day. When these gases combine with oxygen and moistur e, sulfuric acid and nitric acid are formed (Jenner, 1999).The rain will carry the acids to the ground (acid rain) which may cause the depletion of calcium and magnesium in the soil, elements needed by plants for the formation of chlorophyll and wood, or it may cause the release of aluminum in the soil, which are poisonous and can kill the roots of trees. Moreover, nitrous oxide or laughing gas is a colorless gas with a sweet taste and odor that is used as an anesthetic in minor surgery that piss is responsible for about 6 percent of the human contributes to greenhouse warming.Methane or cow gas, on the other hand, makes up about 18 percent of human contributions to greenhouse effect. Cattle, sheep, goats, and other cud-chewing animals give off methane, in burps and flatulence as they digest (Cairncross, 2002). Experts said that what is happening set now is not a liaison of adding a few degrees to the average temperature of a community. A rise of this magnitude may cause life, fo r without the environment, creatures on earth cannot survive (Davidson, 1999). CFCs are estimated to account for 14 percent of global warming.Experts said that what is happening right now is not a matter of adding a few degrees to the average temperature of a community. A rise of this magnitude may cause life, for without the environment, creatures on earth cannot survive With these, are we all aware of the cessation of the damages brought about by modernization? Have we contributed to such environmental dilemma? What have we through with(p) to minimize such danger to our lives? How can we take care of our environment? We must undertake measures to carry on our resources and minimize utilization of energy before its too late.Our fight against pollution is an initial quality toward conserving our environmental resources and energy. We must all join hands for this common goal. If present day emissions of greenhouse gases continue, it is estimated that the rate of increase in globa l specify temperatures will reach about 0. 30 0C per decade. This will mean a likely increase of 1 0C above the present level by the year 2025, and 30 0C before the end of the next century. A. Resolution a. ) Recycling and Reuse of Solid Wastes Solid wastes are now viewed as a potential resource which must be recovered and reused whenever possible.Since disposal forest resources are rapidly being depleted, recycling solid wastes offer a solution to both. Consider the element phosphorus. mine from phosphate ores, it is manufactured into fertilizers. It enters the plant tissues and we obtain it when we eat plant as vegetable. This is later excreted and joins the sewerage system. The sewage system sludge can be used directly as fertilizer or soil conditioner. Used bottles can be used over and over again. Durable plastic containers can be saved for more household uses.Tires can be recapped and used again. Old clothing materials are used as kitchen towels and bags (see Environment Matt ers Industrys Guide to the Issues, the Challenges and the Solutions, 1999). If the materials cannot be used over several times, then they can be shredded and converted into a new form. Old newspapers are repulped into new paper. Broken glasses are ground and manufactured into new ones. Tires are processed to raw rubber. Protein leftovers are manufactured into animal feeds. b. ) Conserving our Forestsevery now and then we receive alarming news about our forests being denuded. Big logging concessionaires licentiously cut down trees without undertaking reforestation measures. Without trees, the soil is loosened and rapid erosion occurs. As a result fertile topsoil is washed away, which makes growth of other forms of vegetation almost impossible. We suffer coarse loss of timber, wildlife, and other forest products. But the greatest danger is the occurrence of floods and global warming that cause losses of food, properties, and lives (Davidson, 1999).
