What is Offsetting improvement In Air Quality During Lockdown?
Coronavirus has cast a worldwide gloom by causing severe harm to health and the economy. To slow the spread, all over the Countries have been lockdown. The biggest coronavirus lockdown in the world is happing at the time in India, there isn’t any flight, no trains, no taxis, and very few essential shops are opened.
On March 24, 2020, the prime minister of India Narendra Modi made an announcement that India would be under lockdown for the next 21 days. The Intention was very clear that He doesn’t want the virus to enter in more than 1.3 billion Indians. Despite it, we haven’t seen the “Flatten curve” of coronavirus cases.
But in the meantime, the 21 days lockdown has shown something else, something amazing, India’s notorious air quality. The speed of the change has surprised not only us but even experts, who have said that it is proof that dramatic improvement in air quality could be obtained.
Days after the lockdown started on March 25, the level of particle pollution (considered to be harmful to health) fell around 60% in New Delhi (The capital of India). According to DTE, In Delhi NCR, the average level of particulate matter size daily is less than 2.5 Micro (PM2.5) and NO2 decreased rapidly form pre-lockdown.
Normally, Delhi is called one of the most polluted cities in the world. At the time people are staying at home, they go out only when they need essential stuff, which is why pollution has reduced and people can see the blue skies, moon, and stars without the usual barrier of smog.
