Out line : Air Pollution’s Effects.
Specific Purpose : To inform my audience about effects of air pollution.
Central Idea : There are three effects of air pollution which are it
damages the natural environment ,atmosphere and
human.
Introduction :
I. Pollution Crisis is a major problem all around the world. It has adversely affected the lives of millions of people and caused many deaths and health disorders.
II. The air pollution is known as a substance in the air that can harmful to every living creature on the planet.
III. Air pollution is responsible for major health effects. Every year, the health of countless people is ruined or endangered by air pollution.
IV. Actually, there are many effects from air pollution, but today I would like to inform you about only three of them.
น วิกฤตมลพิษเป็นปัญหาสำคัญทั่วโลก ได้ส่งผลกระทบต่อชีวิตของผู้คนนับล้านและก่อให้เกิดการเสียชีวิตจำนวนมากและผิดปกติของสุขภาพ.
ii มลพิษทางอากาศเป็นที่รู้จักกันเป็นสารในอากาศที่เป็นอันตรายต่อสิ่งมีชีวิตทุกบนโลกสามารถ.
iii มลพิษทางอากาศเป็นผู้รับผิดชอบต่อผลกระทบต่อสุขภาพที่สำคัญ ทุกปีสุขภาพของผู้คนนับไม่ถ้วนที่มีการทำลายหรืออันตรายจากมลพิษทางอากาศ.
iv ที่จริงมีผลกระทบมากจากมลพิษทางอากาศ แต่วันนี้ผมอยากจะแจ้งให้ทราบเกี่ยวกับการเพียงสามของพวกเขา.
( transition: Let’s start with the first effect of air pollution.)
Body :
I. Air pollution is effected on natural environment and it would cause environmental problems.
A. The increase amount of polluted air will make the acid rain.
1. Acid rain is the rain that forms by water molecules in the atmosphere reacts with sulfur dioxide and nitrogen oxides to produce acid rain.
B. When acid rain occurs, it would cause many effects.
1. The acid rain could make great damages to ecosystem.
2. It’ll destroys habitats of many animals because many tree were dead.
3. Acid rain polluted water and kills many aquatic animals.
(transition: now, let’s move to effects of air pollution on atmosphere.)
II. Air pollution has a lot of effects on the atmosphere.
A. Air pollution destroyed ozone layer in the atmosphere.
1. When ozone layer is destroyed. The greenhouse effect would happen.
2. With less ozone layer, our earth will be hotter because air pollution effect more impact to global warming.
B. Air pollution also has negative impact on climate change.
1. The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather or climate occurs in this layer. The air pollution cause the climate to occurs in unsuitable time.
2. Different occur time of climate that cause by air pollution would make the crops dead and insufficient of water resources.
(transition: now we already know about effect of pollution on atmosphere let’s move to the effect on human.)
III. Air pollution has a lot of effects on human, especially on human health.
A. 2.4 million people die each year from causes directly connected with air pollution.
1. It is estimated that 1.5 million deaths per year as the result of indoor air pollution compared to little less than one million deaths per year caused by outdoor air pollution.
2. These air pollutions were from cars or vehicles that release pollutants in form of smoke.
3. When humans breathe in the smoke. It will effects their health directly and may cause some diseases.
B. There are many diseases that cause by air pollution.
1. Chronic Obstructive Pulmonary Disease (COPD) is a disease spreading quickly due to increases in levels of air pollution.
2. asthma may not be directly caused by air pollution, asthma attacks can be irritant by high levels of air pollution. The health condition asthma can also be caused by air pollution. A pollutant such as sulfur dioxide causes the constriction of smaller airways in the lungs and makes breathing harder even for healthy people.
Conclusion :
I. As we have seen, air pollution is really dangerous and affected our earth.
II. Its effects harm our health, it caused a lot of diseases. Air pollution harms our environments too.
III. In my opinion, I think we should do something to protect our Earth from air pollution, which will make our life better.
