The mixing of gases or particulate matter harmful in the air causes air pollution. Air pollution is not only dangerous for our health, but it also spoils our environment.
Reasons of air pollution
The air around us can be polluted in many ways. The smoke from the factories also pollutes the air. That is why it is harmful to our health. Burning firecrackers on Diwali also contaminates the air.
Smoke consists of very small carbon particles, which sit on the leaves of plants and disrupt the processes of photo-synthesis and respiration. If these particles of dust and carbon enter the human body, then it causes respiratory diseases like tuberculosis (TB), bronchitis.
When sulfur dioxide is found in rainwater, it becomes acidic. And thus acidic rain occurs. Acid rain damages plants and buildings and causes skin diseases in animals.
Chlorofluorocarbons, which are used in the refrigerant's fluid and aroma sprays, also contribute to air pollution. These react with the ozone of the air and eliminate it and due to this, holes have started to form in the ozone layer. Large amounts of the sun's ultraviolet rays reach the Earth through the holes in the ozone layer, which damages plants and causes skin cancer in animals.
When the amount of carbon monoxide and carbon dioxide in the air increases, the air retains more heat inside itself. Due to this, the average temperature of the earth starts increasing. This process is called global warming.
How can we prevent air pollution?
Once the balance of nature deteriorates, it becomes very difficult to improve it. So we should stop air pollution. We can save the air from getting polluted by the following ways:
- Plant trees wherever possible.
- Polluting industries should be kept away from the city.
- Use only those things which do not disturb the environment.
- Put air filters in the chimneys of the industries.
- Use of compact, compressed natural gas in vehicles.
- Take proper care of the machines so that they do not spread too much pollution.
- Stop using chlorofluorocarbons.
