Lockdown Affects Nature: Is COVID-19 Lockdown helping nature?

Lockdown is a measure to control COVID-19 but it controls pollution by limiting emissions of carbon, sewages, poisonous gases this leads to restore the nature. Lockdown applied in more than 200 countries especially, in the countries contributing major industrial share of global production.

Like US,China,Japan,Germany, Europe countries.. Huge industrial shut downs, less traffic in all the ways road, water way  aviation became advantages to nature restoration. All the international flights, domestic flights not allowed to fly. There is no goods transports except essentials as a result fuel consumption became less.
Is nature bouncing back?
Due to less carbon emissions, greenhouse gasses emissions, sewage enters in to water bodies like ponds, canals,rivers and sea. All these activities leads to decrease in global warming, Ozone layer healing, significant decrease in air pollution.

In very rare situations these type of global leads to new breath to the nature and man kind. By keen observation of history after every crisis, decrease in emission of Carbon dioxide(CO2), Nitrogen dioxide(NO2), chlorofluorocarbons(CFC), carbon, carbon monoxide(CO), methane(CH4).... For example the following 3 crisis situations we can find that

• After world war 1 and 2: Industrial infra structure collapsed globally and for some period was like lockdown, to restart the factories and few years latter carbon emissions started increasing. 
• During Soviet Union Collapse: During this world faces recession and industrial sector became inactive and emissions decreased for short while, again started increasing.
• During global financial crisis 2008-09:  Carbon emissions decreased to 1.4% after 9 years i.e: by 2018 increased to 16%.

There are so many pollution control measures like

• Anti pollution acts,1974 water pollution control act,1981 Concerning protection against pollution & Concerning waste, etc.
•  Global environmental movements, 
• Paris agreement on climate change and to control green house gases and carbon emissions, violated by US

All these actions have never given an expected results,but coronavirus lockdown is giving us Unintended Benefits for healthy climate.
Global emissions - Case studies:

• Satellite images given by NASA,ESA,CREA indicates that Venice canal 60 years clear.
• Himalayas looking clear due to decrease in air pollution levels.

• NO2 emission in China decreased 36% less than earlier ,200MT of carbon emissions decreased.
• Green house gases decreased 25% CO2 as 15-40% industrial production under shut down.
• Columbia university research in Network road traffic decrease by 35% as a result CO2 and methane levels decreased.
• Aviation sector contributes 2.4% of CO2 emission and 5% of Global warming, during lockdown all the international air lines and domestic air lines are not permitted to fly.
• Earth's layer protective layer from UV radiations was depleted due to pollution, but during this lockdown restoration of the layer speeds up, actually the major contribution of Ozone layer restoration is Montreal protocol 1987. University of Colorado Boulder.
• Gangatic dolphins more visible in VGBS Bihar India,  due to increase in AQI
• Pollution causes breathing problems, and corona virus effects on lungs and breathing problems so reduction of pollution helps in corona treatment.

As per the article info given by The Guardian.com

• China Italy UK,Germany and other decreased CO2 and NO2 greater than 40%
• Europe reduces 390MT Carbon Emissions
• China reduces 18% carbon emissions
• US fall by 40% CO2

As per the article Forbes.com

Ocean has much needed breathing space.
On the other hand according to the Forbes.com nature healing is not only by lockdown it's also by the precautionary measures and mitigation techniques several countries has crucial role.

Is lockdown needed every year to bounce back nature?
For the reduction of global warming we follow every year like that lock down for few days will helps to restore nature. But good governance needed for pollution free world.

• Effluent plants for reducing air pollution and sewage treatment plants to prevent water pollution needed. 
• Strict guide lines and rules should be followed by government not required any lockdown.
• Pollution control and awareness on protecting nature is not an yearly maintenance, it has to be a part of our life time activity.

Final word:
Nature healing prices is not only by lockdown for decades pollution control measures has been coming in to result now,  lockdown has a role in it. Past history we can get conformation that these emissions may increase in coming years, as every country has to boost up productivity in order to fill economy gap.
