Sixty to seventy percent of children in Bengaluru who breathe poor air get lung diseases.

The “Silicon Valley of India,” Bengaluru, is still praised for its lush vegetation. Due to the cold climatic condition throughout the year it was formerly known as “air-conditioned city. 

Environmentalists, however, worry that poor air quality has put the much desired city in great risk. According to experts, Bengaluru’s air quality is not being monitored properly. They indicated that between 25,000 and 30,000 trees have been felled in Bengaluru over the previous five years. Therefore, the vegetation that would filter out the dangerous components from air is lost.

A.N. Yallappa Reddy, an environmentalist and former bureaucrat, told IANS that Bengaluru has some of the worst air quality in the world. About 60 to 70 per cent of kids have lung-related issues. They are given steroids, making them more prone to diseases like diabetes and obesity. No one is bothered about these developments. It is also not in the government’s agenda, and concern is also not seen,” he said.

Prakruthi Prasanna, who runs Sustainable Environment Development Trust (SEDT), which planted 16 lakh plants in Bengaluru, also told IANS that the quality of air in Bengaluru is not at all good.

“New Delhi emits 14,000 tons, and Hyderabad records emission of 2,400 tons of Co2 per day. Thanks to the greenery left in Bengaluru in the form of the Cubbon Park, the Lal Bagh botanical gardens. It is 1,400 tons per day in Bengaluru,” he stated.

“There is a plan to give readings of air conditions at every traffic signal in Bengaluru. The indicators are being installed. People would come to know the levels of oxygen and carbon dioxide at the junction. An App is being readied in cooperation with the Karnataka State Electronics Development Corporation Limited (KEONICS). It will give an analysis of the damage the existing air conditions can cause,” Prakruthi Prasanna explained.

The sensors have to be adapted to indicators, and in two to three months, it will be operative if everything turns out as planned, he said.

Yallappa Reddy expressed his concern that equipment which gives readings has not been installed where people’s movement and vehicle traffic are high. The entire forecast depends on three to four computers.

They won’t be able to give a proper assessment. The air quality of Bengaluru is affected by vehicular traffic and building construction as well as garbage burning, he added.

All these would cumulatively act on Solid Particulate Matter (SPM). The Particulate Matter goes into the lungs and won’t come out and create respiratory issues. It will also lead to bronchitis and even lung cancer,” he said.

He explained that the government could bring about stringent laws and punishments to stop the burning of garbage and littered leaves. The rules should also be framed to regulate building construction. However, polluters enjoy immunity, and the authorities do not care about the health and social impact, he opined.

The upcoming Deepavali festival will definitely push the air quality in Bengaluru to a new low. People have money, and very costly crackers from China with deadly chemicals are in the market. But, the government seems to be not so bothered, explained Yallappa Reddy.

“The crackers are not necessary. Diwali is a festival of lights, celebrated through lighting diyas, not by bursting crackers. The tradition of burning crackers has been systematically pushed by China. Green crackers are made with the same chemicals. The government should come forward to impose a 100 per cent ban on the bursting of crackers,” Prakruthi Prasanna said.

T.J. Renuka Prasad, a retired professor of geology and co-ordinator of Bio Park in the Jnanabharathi campus, said the Pollution Control Board findings and forecast seem to be doubtful. The concerned department would always give a rosy picture.

Bengaluru city has had allergic elements from the beginning. With the erosion of greenery, it has increased now. The growth of the I.T. industry has added 60,000 to 70,000 pickup and drop vehicles in Bengaluru. Adding to this, a single person driving a car has become a matter of prestige, he explained.

Professor Renuka Prasad said Bengaluru was known as an air-conditioned city earlier. “Our houses didn’t have fans, not about affordability, but the weather in Bengaluru was so good. The air quality is affected by chemical disposal in water bodies. Once the water evaporates, it enters the air and enters our bodies. The chemical input is increasing day by day, which is a concern. The chemical output is either going into the ground or evaporating; both are hazardous,” he said.

Due to the aggressive planting and raising of greenery in the Jnanabharathi campus of Bengaluru University, the temperature on the campus is less than Bengaluru by two to three degrees at any point in time, he explained.

“The first stream order has gone, and second, third and fourth stream orders are vanishing; polluted water is entering storm water drains directly. These stormwater drains are also encroached upon or reduced,” professor Renuka Prasad said.
