Before 200 years ago people ware afraid of wars, famines and epidemics. But today they afraid of a new dangerous like dryness, illiteracy and pollution.

Because of huge increasing in number of factories such as cement and cooper foundries factories, especially that release CO2, the air pollution becomes the most dangerous which humanity is facing today.Every day factories release a large mount of poisonous gases and fumes in the air.

These fumes contains many substances like ammonia and carbon monoxide plus many of toxic trace metals (nickel, selenium) that they consider harmful for habitat and health, because it decrease the amount of oxygen in the air raising our blood pressure and heart pulse so high which lead to shortness of breath and diseases. So factories give us a successful economic but give us also air pollution to. That we can avoid it by using natural powers like water and sun to run our factories.

The big problem is the big source of pollution which comes from the most benefit things and no one can think about the world without these automobiles which help humankind to decrease the time and effort. After all of these problems which must solved there are many solutions on many levels but every thing must start with person because the person can do many things right now to decrease harmful on air.

National organization can make air pollution publicity problem and let people be part in solving this problem.

Thanx Qroooah.. ...

U know wht...

In Australia and because of pollution ,a hole founded in ozone layer so harmful radiations coming from the sun pass threw this hale causing skin cancer to the people living in that country..

So It's really so dangerous & we have 2 face this problem..

&
Hand by hand..We can Get rid of It...

hello every body ........

nice subject ........Air pollution

the tempetreture is encreasing every day ...so that leads to (global worming)...Global worming appears because of humen skills and manifactureing

cars,planes ,factories and... all of them produce pollution ....so scientisits are worred about this problem

i thinks the possible ways to protect out environument we have to :
use environmentally cars and planes also factories .......for instance Solar power is good alternative of oil coz one day the oil will disappear from our life.

what do you think about humen them selves shall they learn how to use these machines and how to deal with polluted things ??? -

In my opinion the first huge cause in the transportation
In the golf countries most of people are driving their own car and don't use and public transport such as bus
so the percentage of the smoke will increase faster and faster
and that will cause ice melting

Thanks a lot

ولد البـــدو · 23 أكتوبر 2011، 12:41

ok members nice opinions

??could you guess some solutions for this problem

توب فاشين girl · 29 أكتوبر 2011، 16:33

The soulations are:

Reduce driving cars
Using bus as much as you can
Use alternative source insted of fossil fuel
Reducing emissions of industrial gases

These soluations that I have

hi sis

nice topic for discussion n

What are the common causes of air pollution?

i think factories and cars

How we can protect our selves from it??

by using filter filtering of smoke from factories and cars
also increasing number trees

How we can save our environment from air pollution?

to be honest i dont think there is a way to protect environment from air pollution

we can reduce it but safe it it is impossible with the development taking place in the word

for example

all words was using gas R22 and R12

but this type of gas harm for air and ozone layer

so now they are using R124A
its better and less damage for air and ozone

so they have to reduce damage and effect but they can safe it 100%

thanx my sis for great topic

keep it up

cheers

nice suggestions

what do you think about the uses of solar car??

and decreasing the use of gazline and also produce pollution by cars

do you think its good alternative from cars ??

but think about the disadvantages [ATTACH=CONFIG]77310[/ATTACH]

firstly i want to thank u my sis for this topic
i think the discussion is good way to improve our lang

>>
yes sis u right the air pollution is common in Oman
>>
the common causes of air pollution is a cars
we note the number of cars in oman is very high
i think that every family in oman has at least 4 cars

to protect our selves from air pollution ti think

we have avoid jam places, and industrial places

to save our environment we have to work hard to reduce use cars

[h=2]Air Pollution[/h]
How Do We Cause Air Pollution?
We cause air pollution directly through our use of electricity, fuels, and transportation.
We also cause air pollution indirectly, when we buy goods and services that use energy in their production and delivery. Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles.
Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result. Using carbon dioxide as an example, the average family in the United States causes air pollution in the following ways:

How Much Air Pollution Do We Cause?

An average family in the United States causes the following amounts of air pollution each year:

[TABLE='class: MsoNormalTable, width: 413']
[TR]
[TD='width: 272']Climate Change Pollution (CO₂) = 85 Tons
Ozone-Causing Pollution (NOx) = 325 Pounds
Acid Rain Causing Pollution (SO₂) = 411 Pounds
Small Particulate Pollution = 43 Pounds
Toxic Lead Pollution (Pb) = 1.2 Ounces
Toxic Mercury Pollution (Hg) = 0.04 Ounces
[/TD]
[TD='width: 135, bgcolor: silver']

And each year, the average individual in the United States causes the following amounts of air pollution:

[TABLE='class: MsoNormalTable, width: 413']
[TR]
[TD='width: 272']Climate Change Pollution (CO₂) = 27 Tons
Ozone-Causing Pollution (NOx) = 102 Pounds
Acid Rain Causing Pollution (SO₂) = 129 Pounds
Small Particulate Pollution = 14 Pounds
Toxic Lead Pollution (Pb) = 0.4 Ounces
Toxic Mercury Pollution (Hg) = 0.01 Ounces

Health Effects of the Pollution We Cause

Exposure to emissions of lead, mercury, sulfur dioxide, particulate matter, carbon dioxide, and ozone-forming nitrogen dioxides are hazardous to public health. Toxic compounds, like mercury and lead, poison organ systems and can lead to brain damage and death. In parts of the country where lakes and waterways have been contaminated with mercury from electric power plants, fish are no longer safe to eat because they, too, are contaminated with heavy metal pollutants. Other pollutants, like ozone and particulate matter, cause respiratory and other health problems, particularly in children and the elderly.

Environmental Effects

Climate change on a global scale has been attributed to increased emissions of carbon dioxide (CO₂), a greenhouse gas. A global average temperature rise of only 1C could have serious implications. Possible consequences include melting of polar ice caps; an increase in sea level; and increases in precipitation and severe weather events like hurricanes, tornadoes, heat waves, floods, and droughts. Indirect effects include increases in infectious disease, weather-related deaths, and food and water shortages. All these effects put a stress on ecosystems and agriculture, and threaten our planet as a whole.
Other atmospheric effects of air pollution include urban smog and reduced visibility, associated with ozone-forming nitrogen oxides and volatile organic compound emissions. Sulfur dioxide and nitrogen oxides combine with water in the atmosphere to cause acid rain, which is detrimental to forests and other vegetation, soil, lakes, and aquatic life. Acid rain also causes monuments and buildings to deteriorate.

Economic Effects

The effects of air pollution on human health and the environment have economic impacts. According to the Healthy People 2000 report ^[5], each year in the United States:
The health costs of human exposure to outdoor air pollutants range from $40 to $50 billion.
An estimated 50,000 to 120,000 premature deaths are associated with exposure to air pollutants.
People with asthma experience more than 100 million days of restricted activity, costs for asthma exceed $4 billion, and about 4,000 people die of asthma.
The Environmental Defense Fund (EDF) article, "Why is it Better to Buy Green Electricity?"^[1], states that acid rain causes $6 billion a year in damage to crops, forests, lakes, and buildings. The potential economic impact of global warming is estimated to be in the billions of dollars. While green sources of electricity may cost more, they do not incur the external costs of traditional fossil fuel-based generation. The EDF article states that:
"Increasing reliance on green sources reduces financial risks such as future regulations, taxes on greenhouse gases, and price fluctuations associated with fossil fuels. Green resources increase U.S. energy self sufficiency, and thus economic security, by reducing reliance on fossil fuel imports. They also help reduce current rapid depletion of natural resources.
Green resources are a good source of jobs and income because they rely on local labor, land, and resources. Rural communities would probably benefit the most from renewable energy development, as wind and biomass energy production is likely to take place in rural areas."

What You Can Do

There are many actions people of all ages can take to reduce their emisisons. To learn more, read the checklist of things you can do in your home and in your school in the Cleaner and Greener Program's "Guide to Air Pollution and the Emissions We Cause." If we all work together, we can make the world a cleaner and greener place to live!
