Today I thank everyone present here. Today I want to talk with all of you about the problematic situation of Air pollution and its reasons.
At first we have to know that what Air Pollution is.
It is the presence of substances in the atmosphere that are harmful and hazardous to the health of humans and other living beings and also one of the main causes of damage to the climate.
For the humans, air pollution results in inhalation of harmful gases and cause of many respiratory and pulmonary diseases. Some of these gases are (such as carbon monoxide, sulphur oxide, methane, ozone etc.)
The main causes of Air pollution:
The main causes of air pollution can be depicted as our craving for the modern lifestyle which is causing great harm to the Mother Nature. In the last few decades the use of various types of motor vehicles has increased a lot. The emission of the harmful gases and dust particles causes great harm to the environment. These harmful substances increase the ppm level very fast. These are playing a great part in causing damages of our healthy life.
Another problem can be pointed out as the production of harmful smokes and poisonous gases of the various chemical factories. The rapid increase in the use of air conditioners can also be seen as a great threat to our environment and healthy lifestyle. Human practice of fossil fuel in various places can be another cause of the production of some air pollutants.
The air pollutants have adverse effects on the ecosystem of any living being. The natural pollutants can come from the volcanic eruptions, which creates various harmful gases and particles.
Another air pollutant like ammonia can be emitted mainly by agricultural wastages.
The effects of Air pollution:
The harmful gases and particles as presented in the air are inhaled by the pregnant women cause’s great damages to their unborn child. These can be resulted in the frightening respiratory diseases of the newborn children than the other children.
Another man-made disaster like the cutting of trees and plant also harms the balance of the nature cause us to live in a polluted environment. This deforestation harms greatly the Ozone layer resulting in the devastating process of global warming, which leads to the destruction of the natural cycle.
The pollutants are also the cause of acid rains which becomes a fatal danger for a great number of animals and the marine creatures.
The disease like asthma becomes an illness of some of the children from their birth.
Nature is the greatest treasure of all living beings, it nurtures us like our mother. But if we want our next generation to live healthily and happily we have to take great care of our mother nature.
We have to stop the practice the cutting green trees and plants in order to stop the pollution.
All humans have to use the vehicles like cycle as much as possible to decrease the emission of the harmful gases.
Therefore let us try our best to make our nature healthy for ourselves.
A Speech On Cause And Effect Relationship Of Air Pollution
Air pollution is any physical, chemical or biological change in the air. It is rather the contamination of air by harmful gases, dust and smoke which severely affects plants, animals and humans.
There is a balance of gases present in the atmosphere. A little increase or decrease in the composition of these gases is harmful to survival. This imbalance in the composition of gases has resulted in an increase in earth’s temperature, which is known as global warming.
There are two types of pollutants in the air.
Primary pollutants are those that directly cause air pollution. Sulfur-dioxide emitted from industries and factories is a primary pollutant.
Secondary pollutants are formed by the mixture and reaction of primary pollutants. Smog, produced by the intermingling of smoke and fog, is a secondary pollutant.
There is visible and invisible air pollution as well. The smog that is seen lingering over a city is a good example of visible pollution. Whereas invisible pollutants are not as noticeable, but they can be equally deadly. Examples of invisible pollutants include nitrogen oxide, sulfur dioxide, carbon monoxide, etc.
There are many causes responsible for air pollution.
1. Fumes released from vehicles:
The major source of air pollution is vehicle exhaust fumes, which releases high amounts of carbon monoxide. Hence there is no surprise that carbon monoxide happens to be the largest air pollutant in the United States.
Each day millions of vehicles are operated, all of them leaving its own carbon footprint on the environment. This is why electric vehicles are in a rise in the automobile marketplace as people want to rely less on fossil fuels to power their cars, leading to less toxic emissions into the environment.
2. Power plants run by fossil fuels:
Fossil fuels also create a big problem when they are burned for energy in power plants. Chemicals such as sulfur dioxide are released during the burning process, which goes straight into the atmosphere. These pollutants react with water molecules to build up something called ‘acid rain’.
3. Exhaust from industrial plants:
Like the vehicles the exhaust from the heavier machinery located inside big factories and industrial plants also emit pollutants into the air.
4. Construction and Agriculture:
Daily dirt and dust released into the atmosphere from excavating and demolition type construction activities. Ammonia, a frequent by-product produced from agricultural activities is one of the most dangerous gases in our environment.
5. Natural Causes:
Volcanoes, forest fires, and dust storms are natural events create good amounts of air pollution into the environment.
Some of the effects of air pollution are –
1. Global Warming.
Air pollution accelerates the rate of the depletion of the Ozone layer. Global warming means increased temperatures Earth experiences. These higher temperatures lead to the melting of the polar ice caps and icebergs, which increases sea levels.
2. Respiratory and Heart Concerns.
Air pollution causes irritation in the eyes, lungs, nose, and throat. It creates respiratory problems and worsens conditions such as asthma and emphysema.
When humans are exposed to air pollution on a daily basis, they become at higher risk for cardiovascular disease.
