assalamualaikum and hello to all fantastic group members...
actually, i want to thank to all of you about today presentation.
i know we do not do very well in our group presentation today, but in my opinion, we do well in the other ways, that is in our team cooperation and spirit.
we do discussion, give suggestion and opinion about what and how we want to do for the group presentation. think about it...
although sometime we have a different suggestion and opinion about each part, but we discuss again by together to make sure we can get the true point or supporting detail to support that part. lastly, we got the true ones...is it right...?
actually, what we had done today is our own mistake and it is under our own responsibilities because we do not prepare ourself early...we do the last minutes preparation...huh...
thats all what i want to say about our group presentation. if you all have anything to add in, please comment my post to give your opinion about our group presentation...

before i forgot, please make sure all of you log in to our blog to give your comment to all the topic or title...actually, we must do discussion in our blog also...
then, to fathi, please make sure our final draf are ready...we try to submit it by this wednesday...okay...

annauncement.

assalamualaikum and hi to all my group members.
please prepare your own power point based on your own point to present it on monday, october 20.
after do the power point please email it to fathi adha. we combine our power point slide to become 1 folder.

ways to overcome air pollution

We have the effects of air pollution and so on. Know here we will talk about way to overcome air pollution. Everyone can play a part to reduce air pollution. There are many ways to overcome the air pollution such as reduce vehicle emissions, reduce industrial emissions, reduce emissions from power stations, use renewable energy, and reduce the use of chlorofluorocarbon (CFCs). (http://library.thinkquest.org/C0111401/dealing_air_pollution.htm).

First way to overcome air pollution is reduce vehicle emissions. This can be done by installing catalytic converters in every car so that the amount of toxic gases released is reduced. A more effective way is to reduce the number of vehicles on the road. For example, in Manila, the government has introduced regulations such that on different days, only cars with certain number plates can be driven. Another way is to encourage the public to take public transport. We can choose to take public transport to reduce air pollution. (http://library.thinkquest.org/C0111401/dealing_air_pollution.htm).

The second way is more to industrial and the governments responsible. They must reduce industrial emission to overcome air pollution. Industries can reduce the amount of air pollutants they release by installing scrubbers, which are capable of removing up to 90 % of sulphur dioxide from waste gases. (http://library.thinkquest.org/C0111401/dealing_air_pollution.htm).

Other than that, we also need to reduce emissions from power stations. This method concerns us, consumers of electricity, greatly. If electricity is used, less fossil fuels have to be burnt, and less air pollution would be emitted. We can do our part to reduce air pollution by conserving electricity at home, at school and at work. (http://library.thinkquest.org/C0111401/dealing_air_pollution.htm).

We also can use the renewable energy to overcome the air pollution in our country or world. Renewable energy such as wind and hydroelectric, does not pollute, unlike traditional sources of energy that depends on the combustion of fossil fuels. (http://library.thinkquest.org/C0111401/dealing_air_pollution.htm).

Last but not list to overcome air pollution is by reducing the use of chlorofluorocarbon (CFCs). The effects of ozone depletion are disastrous. Chlorofluorocarbons or CFCs is the gas that is responsible for ozone depletion. By reducing the emission of CFCs, we can significantly slow down the rate of ozone depletion. Use 'green' products which utilizes ozone-friendly in places of CFCs. (http://library.thinkquest.org/C0111401/dealing_air_pollution.htm). Beside that, we can place the CFCs to Hydrochlorofluorocarbons (HCFCs) to overcome the air pollution.

first draft outline.

1.0 Introduction

The title of this paper is air pollution. In this paper, we will discuss the definition, causes, effects and ways to overcome air pollution.

1.1 Definition

. Human introduction into the atmosphere of chemicals, particulate matter, or biological materials that cause harm or discomfort to human or other living organism, or damage the environment.

2.0 Sources of air pollution.

2.1 Carbon dioxide

2.2 Sulfur and chlorofluorocarbons (CFCs)

2.3 Chlorofluorocarbons (CFCs)

2.4 Smog

3.0 Causes/contributing factors

3.1 Natural phenomena

· Volcanoes, forest fires, dust storms.

3.2 Human activities

· Using aerosol cans, personal vehicle and commercial vehicles, factories activities (radioactive)

4.0 Effects

4.1 People

· Cause short-term such as eye and throat irritation.

4.2 Animals and plant-life

· Such as sulfur dioxide, nitrogen oxides, ozone

· Cause direct damage to leaves of crup plants.

4.3 Health

· Difficulty in breathing, wheezing, caughing and aggravation of existing respiratory.

4.4 Biodiversity

· Example, prolonged exposure of the vegetation.

4.5 Acid Rain

· The phenomena accurs when sulphur dioxide and nitrogen oxides from the burning of fossil fuels.

5.0 Ways to overcome

5.1 Use energy efficiently and switching to alternative energy sources.

5.2 Decrease using vehicle on the road.

5.3 Avoid open burning.

5.4 Replant trees and avoid purchasing products.

6.0 Conclusion

The aspects that were discussed in this paper are definition, sources, causes, effects and ways to overcome air pollution.

We must avoid or decrease the air pollution and the other pollutions to make our life better. We should do cooperate to solve this problem because we need to breathing in the fresh air.

AIR POLLUTION...

1. DEFINITION
-Human introduction into the atmosphere of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the environment.
-As the presence in the outdoor atmosphere of one or more contaminants(pollutions) in quantities and duration.

(edited by David H. F. liu, Bela G. Liptak, Lewis Publisher, 2000)

2. SOURCE OF AIR POLLUTION
-various locations, activities or factors which are responsible for the releasing of pollutants in the atmosphere. This source can be classified into 2 major categories which are:
(a) Anthropogenic source (human activities)
* mostly related to burning different kinds of fuel

(source: http://en.wikipedia.org/wiki/air_pollution)

(b) Natural sources
* large areas of land with little or no vegetation
* smoke and carbon monoxide from wildfres.

(source: http://en.wikipedia.org/wiki/air_pollution)

3. CAUSES OF AIR POLLUTION
(a) Energy consumption
* the burning of fossil fuels to produce electricity or to power transportation vehicles.
(source: http://answer.yahoo.com/question/index?qid)

(b) Acid rain
* significant air pollution problem that affects rural, suburban and urban areas that are down-wind of major industrial areas.
(source: http://answer.yahoo.com/question/index?qid)

(c) Global warming
* happening now and affects everyone.
(source: http://answer.yahoo.com/question/index?qid)

4. EFFECT OF AIR POLLUTION
(a) Peoples, animals and plant-life
* can cause short-term effects such as eye and throat irritation.
* such as cancer and damage to the body's immune, neurological, reproductive and respiratory systems.
(source: http://answer.yahoo.com/question/index?qid)

(b) Childrens
* due to their size and the fact that they are in the process of developing are at greater health related risk.
(source: http://answer.yahoo.com/question/index?qid)

(c) Atmospheric effects
* changes in urban climatological characteristic
* increased frequency of rainfall and attendant meteorological phenomena.
* global warming.
(cource: edited by David H. F. liu, Bela G. Liptak, Lewis Publisher,2000)

(d) Effects of topography on air motion.
* micro and mesoscale air motion near point and area sources.
(cource: edited by David H. F. liu, Bela G. Liptak, Lewis Publisher,2000)

5. HOW TO SOLVE
(a) Using energy more efficiently and switching to alternative energy sources.
(b) Decrease using vehicles on the road.
(c) Avoid open burning.
(d) Using Hydrochlorofluorocarbons (HCFC).
(e) Recycle newspapers, aluminiums, and other materials.
(f) Replant trees and avoid purchasing products.
(source: http://healthandenergy.com/air_pollution-causes.htm)

6. CONCLUSION.
-Air pollution is one type of pollution in the world. We must avoid or decrease the air pollution or other pollution to make our life better. We must cooperation to solve air pollution because we need to breath in the fresh air.
