"Air pollution happens when solid and liquid particles—called aerosols—and certain gases end up in our air. These particles and gases can be bad for the planet and people's health. Any particle that gets picked up into the air or is formed from chemical reactions in the air can be an aerosol. Many aerosols enter the atmosphere when we burn fossil fuels—such as coal and petroleum—and wood. These particles can come from many sources, including car exhaust, factories, and even wildfires. Most of the air pollution takes place due to the burning of fossil fuels such as coal, oil, gasoline to produce energy for electricity or transportation. The release of carbon monoxide at a high level indicates how much fossil fuel is burned. This also emits other toxic pollutants in the air. Industrial activities emit several pollutants in the air that affects the air quality more than we can even imagine. Particulate matter 2.5 and 10, Nitrogen dioxide, Sulfur dioxide, and carbon monoxide are key pollutants that are emitted from industries that use coal and wood as their primary energy source for the production of their goods. The use of toxic products also called Volatile Organic Compounds (VOCs), inadequate ventilation, uneven temperature, and humidity level can cause indoor air pollution. Climate change is not just increasing wildfire but also spiking air pollution. Burning stubble and farm residue is also a major contribution to wildfire. It causes increased PM2.5 in the air which collides with other harmful substances like chemical gas and pollen creating smog. Smog makes the air hazy and people find it difficult to breathe. When the car burns gasoline, it emits pollutants in the air which is as harmful as smoking 10 cigarettes a day. Your vehicle emits carbon monoxide, hydrocarbons, nitrogen oxide, and particulate matter. When vehicle pollution is high in the atmosphere, it creates a hole in the ozone layer contributing to smog and causing various health issues. During the clean air act movement, the Central Pollution Control Board (CPCB) registered the highest number of air pollution complaints in the Delhi NCR due to construction pollution and demolition activities. With the rise of population in the city, construction and demolition is a part of the ever-going development phase of the national capital. Several construction sites and raw materials such as bricks and concrete cause haze and foul air which is hazardous for people especially, children and elderly citizens. At the rate with which air pollution is increasing in the country, immediate action has become an absolute necessity. Not only does it affect human lives but also causes havoc in nature."
