Pakistan’s second largest city Lahore has once again topped the daily ranking of the most polluted cities in the world, leaving authorities scrambling to fight the environmental crisis.Lahore, capital of Pakistan’s Punjab province and home to more than 11 million people, repeatedly replaced New Delhi as the world’s most polluted city in November. Even though they have sealed over 500 industrial units and imposed heavy fines on smoke emitting vehicles and brick kilns,” said Amir Farooq, the official in charge of fighting pollution in Punjab.Air pollution in Lahore is nothing but a failure of the government,” the city is producing the same amount of pollution every single day throughout this year and unfortunately government agencies’ action in the winter season is nothing but a “panic response”. However yet, the current situation in Lahore is most alarming, with its fine particulate count repeatedly rising well above 40 times the World Health Organization’s air quality guideline values. The solution is beneficial but effortable by trees through this method. Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark. Because of the relationship between the trees and air pollution is a complicated one. Particulate matter suspended in polluted air tends to settle onto leaves, and certain gases including nitrous dioxide (NO?) are absorbed by leaves’ stomata, filtering the air and reducing pollution levels slightly. But trees and other vegetation also restrict airflow in their immediate vicinity, preventing pollution from being diluted by currents of cleaner air. In particular, tall trees with thick canopies planted alongside busy roads can act like a roof, trapping pockets of polluted air at ground level. To reliably improve air quality, city planners need to give careful consideration to how trees are placed.
