Answer:
1. Improvement in air quality
New Delhi was ranked as the most polluted city in the world by WHO in May 2014. The usual air quality of India’s national capital according to the air quality index used to be 200. When the pollution level hit its peak, the pollution level soared to 900 and sometimes, off the measurable scale.
While 200 itself is 25 percent above unsafe level as deemed by World Health Organization, but as Delhi’s 11 million registered cars were taken off the roads and factories and construction were ground to a halt, AQI levels have regularly fallen below 20. The skies are suddenly a rare, piercing blue. Even the birdsong seems louder.
In the capital of New Delhi, government data shows the average concentration of PM 2.5 plunged by 71 percent in the space of a week -- falling from 91 micrograms per cubic meter on March 20, to 26 on March 27, after the lockdown began.

India Today got talking to a CPCB scholar who is involved in the Clean Ganga project when asked about the rapid improvement in the water quality of Ganga water in Haridwar the source said that "the major pollutant of the river water was Industrial and Municipality wastewater."
