Pushpa Gujral Science City celebrated World Ozone Day by organising a webinar on Good Ozone vs Bad Ozone. Around 150 school students from all over the state participated through virtual mode. Dr Umesh Chandera Kulshrestha, Dean, School of Environmental Science, Jawaharlal Nehru University, New Delhi, was the key speaker at the occasion. He delivered a special talk on Good Ozone and vs Bad Ozone. He said the ozone occurs in two layers of the atmosphere. The layer closest to the Earth’s surface is the troposphere. Here, ground- level or “bad” ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation. The stratosphere or “good” ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the ultraviolet (UV) rays. — TNS

The Tribune, now published from Chandigarh, started publication on February 2, 1881, in Lahore (now in Pakistan). It was started by Sardar Dyal Singh Majithia, a public-spirited philanthropist, and is run by a trust comprising five eminent persons as trustees.

The Tribune, the largest selling English daily in North India, publishes news and views without any bias or prejudice of any kind. Restraint and moderation, rather than agitational language and partisanship, are the hallmarks of the newspaper. It is an independent newspaper in the real sense of the term.

The Tribune has two sister publications, Punjabi Tribune (in Punjabi) and Dainik Tribune (in Hindi).
