Air pollution is one of the major challenges faced by humanity in recent times. In simpler terms, it can be defined as the mixing of external harmful gases and particles in the atmosphere. Such dangerous gases mix with the air we breathe, which ultimately passes into our bodies through inhalation and causes respiratory disorders and death.
Have you ever heard the term ‘pollutants’? Pollutants are the substances that cause pollution. There are mainly two types of air pollutants – one is the primary pollutant, and the other one is the secondary pollutant. Primary pollutants are the substances that directly cause air pollution. For example, Sulphur dioxide discharged from industries. It requires no other substance to react and produce pollution. The secondary pollutants are the substances formed by the combination and reaction of the primary pollutants. We are all familiar with the substance – ‘smog’, right? Smog, formed by the mixing up of smoke and fog, is a perfect example of a secondary pollutant. To eradicate air pollution from our planet, we have to control the production of pollutants. For our better future, let’s join hands – to limit the release of greenhouse gases into the atmosphere, avoid unwanted plastic usage, stop using personal vehicles to travel shorter distances, use clean energy resources like wind, solar, and geothermal energies, manage industrial wastes effectively, minimise the use of fire products, try to follow the three R’s – Reduce, Reuse, and Recycle, and conserve and plant more trees. Other than all these, there are numerous measures that can be taken to reduce air pollution. The foremost thing is to be a responsible human being. Realise that protecting our home is never a duty but our responsibility.
‘Air Pollution in Delhi’ has been a grave concern for a long time now. But still, there has been no solution to this problem. Delhi is considered one of the most polluted cities in the world. According to the World Health Organisation (WHO), Delhi has been ranked as the world’s worst pollution hotspot. The magnitude of pollutants present in the ‘Capital of India’ is massive. Contaminated air present in the atmosphere is causing devastating impacts on the health of the individuals and the environment. It is shocking to perceive the truth that the quality of air in Delhi is six times more polluted than the quality of air that is safe for human beings.
Do you know which are the 30 worst polluted cities in the world? It is really shocking to find that nearly 20 cities on the list are in India. Population explosion is one of the major reasons responsible for air pollution. As per the records, the number of people living in cities has increased dramatically over these years. There is a rise of about 25 per cent in the total population, making it hard for the nation to control pollution. Some of the main sources of air pollution in Delhi include the exhaustion of gases by vehicles, open waste mismanagement and burning, discharge of wastes from industries, combustion of fuels for cooking, etc. Apart from all these above-mentioned sources, the smoke and contaminants discharged during a public festival is also a major contributor to air pollution.
COVID19 pandemic has taught us many lessons in our lives. One such lesson is that it made us realise that the intensity of pollution can be controlled if people are ready to act responsibly for preserving nature. So let us plan and act together for a better future.
Air pollution causes an imbalance of gases in the atmosphere, and global warming is one of the aftereffects of such loss of balance. As we all know, our atmosphere is well balanced with different gases in it. A slight variation in the arrangement of these gases is enough for the disintegration of the balance of our ecosystem. Greenhouse gases act as pollutants and result in the contamination of the air. It traps the heat produced by the sun inside our planet and ultimately results in the global temperature rise.
Other than global warming, the catastrophic effects of air pollution include acid rain, depletion of the ozone layer, loss of ecosystem, respiratory diseases, increase in infant mortality rate, extinction of wild species, drought and so on. So the responsibility to maintain the balance of a certain percentage of gases in the atmosphere is ours. For our survival, it has to be controlled.
“Polluting the air is even more foolish when it is done through a fire that is fuelled by the trunk or branches of a tree.” These are the words said by Mokokoma Mokhonoana, an author from South Africa. It’s high time to stop our irresponsible behaviour towards our mother nature. So let’s join hands for a fresh and safe future.
