How are rivers benefited by lovkdown explain in 150-200 words..please help me!!

Answer:The Hindon, the Yamuna, the Ganga...all of them in the Ganga basin, usually these rivers receive heavily polluted industrial discharges, but as industries have come to a halt in India, their water quality is showing signs of improvement. India started a nationwide lockdown on March 24 in order to prevent the spread of COVID-19, to last 21 days.
Water quality in the Ganga shows a 40 to 50 per cent improvement, according to Dr. PK Mishra, professor of Chemical Engineering and Technology at the Indian Institute of Technology (Banaras Hindu University) in Varanasi, Uttar Pradesh, reports the Business Standard.
Locals in Kanpur and Varanasi have observed water quality improvements, though water levels in the river are low. They expect the Ganga to look clean once the water levels are higher.
The current situation is an opportunity to assess the impact of industrial pollutants on the river
Similarly, the waters of the Yamuna River, a tributary of the Ganga that flows through Delhi, also look more blue than ever. Although the relief is temporary, lessons may be learned from it. The Central Pollution Control Board (CPCB) will be doing a study on the change in river water quality, informs the Times of India.
A 22 km stretch of the Yamuna that flows through Delhi, less than 2% of its total length, accounts for 76% of the pollution in the river. Although industries are required to be connected to a common effluent treatment plant, last year the Delhi State Industrial and Infrastructure Development Corporation fined 910 industries for direct discharges into drains that flow into the Yamuna River.
The current situation is an opportunity to assess the impact of industrial pollutants on the river, in contrast with the impact of untreated sewage which currently continues to be discharged into surface waters.
Answer:
No one was sure that there would be a day when they would see, at least in this lifetime, nature recovering after a fallow due to excessive pollution including dumping of industrial and domestic waste, irresponsible chopping of trees, and every possible abuse. But, the lockdown has turned the tables. Not just the skyline is becoming clearer with each passing day, the rivers are visibly purer, and the once endangered flora and fauna is now coming back to life. Here’s a glimpse of how the Earth has healed itself amid the lockdown.

Our Lifelines — Rivers
You can see the surface of river Ganga, which could not be cleaned despite spending crores of rupees is now cleaner than ever as reportedly none of the industrial waste is being dumped in it. According to a report in HT, Ganga may be cleaner today, than it was in 1986 — the year when efforts to clean the river were first launched. And, a similar case is with Yamuna. Due to a blanket reduction in industrial pollutants, and increased discharge of water from Haryana to Delhi, a cleaner Yamuna is visible these says. Both the factors have increased the self purification capacity of the river.

Clear skies, and clearer skyline
With absolutely limited movement of vehicles on the roads, most of the metro cities in India are breathing in much cleaner air with relatively safer levels of pollutants to deal with, as compared to the time before the lockdown. Metro cities have reported ‘satisfactory’ AQI, and those who had been battling smog in Delhi-NCR can vouch for it anytime!

Feathers flock together
The news of pink flamingoes return in huge numbers to Mumbai beach is certainly something to rejoice about. The reduction in intensity of human activities at and around the city is being touted as a major reason for the possibility of flamingos to flock the city in such large numbers. The Bombay Natural History Society has stated that their number is 25% more than it was in the last year.

A Himalayan view
People in Jalandhar can see Himalayas from their roof top, for the first time in decades! The lockdown has cleared the air pollution to the extent that people in Punjab could catch a sight of Himalayas from some of its cities. The Himalayan range is more than 100 miles away from Punjab, and when spotted, its sight left many in awe!
