Smog also contribute as one of the major outbreak for environmental deterioration.

Smog is also known as a photochemical haze which is caused by the action of solar ultraviolet radiation on atmosphere polluted with hydrocarbons and oxides of nitrogen especially from automobile exhaust. Smog is a devastating problem especially due to the fast modernizationIt is caused by chemicals, automobiles, industrial waste and vehicle’s exhaust fumes and much more. It is formed by the interaction with sunlight with different types of chemicals in earth’s atmosphere.

Smog is hazardous in so many ways. It’s a notable threat to mother earth and every being living on it. These toxic fumes may increase the air concentration and lead to numerous undesirable health effects, economic, environmental destruction .When a town or a city is covered in smog its consequences are faced there and then. Dense smog is liable for decreasing UV radiation greatly, which means damaging the ozone layer thus acting as harmful rather than being a safety as ozone is a layer in atmosphere preventing the UV radiation from sun on the earth.

We should lessen the use of products that release high levels of VOCs. For example, use low-VOC paints.Drive less. Walk, bike, carpool, and use public transportation whenever possible. Avoid gas-powered yard equipment, like lawn mowers and prefer electrical appliances. We should Fuel up during the cooler hours of the day either late night or early morning. This prevents gas fumes from heating up and producing ozone. These slight changes will lead to a major positive change.

Unfortunately Pakistan is one of the county facing this immense problem. Lahore and other areas of northern and central Punjab are usually encircled by a thick layer of smog with sunshine becoming totallyimperceptible as haze spread over the sky.

The Punjab capital is ranked the second most polluted city in the world, according to Air Visual, which records air pollution levels across the globe in real time. The issue of smog started in 2006 and it is increasing since then.
Whereas Karachi is the seventh most polluted city in the world with an AQI of 167 and is classified as ‘unhealthy’.

Hence it is necessary to take measures regarding the increase in environmental degradation caused by polluted air.
