Introduction to the importance of a healthy respiratory system

The respiratory system is a biological system consisting of specific organs and structures used for the process of respiration in an organism. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment, which means the quality of the air can have significant effects on our respiratory system. As air moves into our lungs, harmful substances in the air may enter too. These harmful substances can cause disease or even death.

The air pollutant may also include:

Types of air pollutant
Source
Damaging effects
Tar
Cigarette smoke
Causes lung cancer
Nicotine
Cigarette smoke
Causes addiction to smoking
Carbon monoxide
Cigarette smoke, car exhaust
Reduces amount of oxygen in the blood
Sulphur dioxide
Industry, vehicles
Damages lung tissues
Hydrocarbons
Industry, vehicles
Causes cancer
Nitrogen oxide
Industry, vehicles
Interacts with hydrocarbons to form haze
Haze
Industry, vehicles, open burning
Causes breathing difficulties

Effects of the air pollution to our respiratory system

Lung cancer
-Is a disease characterized by uncontrolled cell growth in tissues of the lung. If left untreated, this growth can spread beyond the lung in a process called metastasis into nearby tissue or other parts of the body. It is caused by the carcinogens such as tar in the cigarette.

Asthma
- is a common chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction and bronchospasm. Common symptoms include wheezing, coughing, chest tightness, and shortness of breath.

Ways to improve the quality of air

Improving indoor air quality
No smoking at indoors
Make sure there is a steady supply of fresh air.
Minimize air conditioning use
Keep carpets and floor dust free
Maintain a low humidity to prevent mould growth.
Improving outdoor air quality
Plant more tree
Walk, ride a bicycle, car pool or use public transportation.
Keep the motor vehicle well maintained
Use a fuel-efficient vehicle.
Implement laws and regulations to control air pollution.

Ways to maintain the quality of air

Look for the most efficient, lowest polluting model or even a zero-polluting electric car.
Prevent open burning
Install catalytic converter in the car exhaust
Use more public transport
Try to use the newest car and engine
Turn of the lights and other electrical appliances there are not in use
Choose he energy efficient appliances when buying new ones
Do not smoke
Reduce, reuse and recycle
Car-pool with your friend

Air pollution is very harmful to respiratory system. Besides, it also brings to many problems, such as ozone layer of the earth being destroyed, falling of sour rain and so forth. One of the factor is smoking. Smoking is known as a portable air pollutant. It is not only harmful for you but to the environment and all of us. Besides smoking, we should walk and cycle more and reduce the usage of automobiles. According to a research on Malaysian, 1/3 of our people suffer from obesity. It is not only better for our health but also save our environment. So, let’s quit smoking and walk more.
The air pollution is not only cause by the emission of gases and cigarette smoke, it is also cause by the quarries, military weapon test including nuclear bomb and also farming. The methane is a type of greenhouse gas which cause the larger effect compare with the carbon dioxide (20 times greater impact over 100 years) and causes degradation of ozone layer that emits by the animal husbandry. Moreover, it will also cause a domino effect to the global warming. The faster the ice melts in poles that cause by global warming, the more methane is release form underground due to the rotting of the dead plants and animals.
In conclusion, to maintain our healthiness of our respiratory system, we should stand up together to fight the air pollution with the government and NGOs. It is not only their responsibility in maintaining the air pollution, it is also ours. We should also educate the younger generations to take care and protect our environment.

Together, let’s keep the world peace, no wars and go green, go vegetarian!
