New virus pandemic – the coronavirus is already present around the world. People suffer from its causes not only through illness or economic crisis, but also by losing their lives.

Around the globe, the coronavirus has already consumed around 280,000 human beings. Society suffers from separation from loved ones, and older people need to be more careful and take advantage of the help of volunteers. Due to the implementation of quarantine, most of the buisnesses were closed, which put the global economy at a level it has not been in for several decades, and these are just some of the negative effects of the coronavirus pandemic.

In all this tragedy, however, benefits nature, which only now, after a long break can fully breathe. When the economy works unchanged – Man exerts a strong impact on nature and its condition. People and their inventions are the cause of smog, contamination of rivers and seas.


The effects of quarantine could be seen immediately. Major cities that suffer from the world’s worst air pollution have seen reductions of deadly particulate matter by up to 60% from the previous year, during a three-week lockdown period. Out of these extraordinary circumstances, we can see how changes in our society’s activities can have a momentous impact on our environment and the air we breathe.

The Indian capital New Delhi — which tops the world’s most polluted city lists — saw a 60% reduction in PM2.5 levels (PM2.5 – harmful microscopic particulate) from March 23 to April 13 from the same period in 2019. PM2.5 is considered dangerous because it  it can lodge deep into the lungs and pass into other organs and the bloodstream, causing serious health risks.

Air pollution is already a global public health crisis, as it kills seven million people each year, according to the World Health Organization. Reducing global heat-trapping emissions is the best way to clean up our sky and prevent avoidable pollution-related deaths, scientists say.

The Chinese city of Wuhan (city of 11 million people in central China’s Hubei Province) , where the deadly virus was first identified, saw a 44% reduction in air pollution levels.

China, air pollution change before and during coronavirus quarantine

In Venice, which is visited by 4.5 million tourists annually, by inhibiting tourism, crystal clear water appeared in the famous canals, and fish and jellyfish, or even dolphins,  which have not been seen there for a long time, because the water was very polluted.


Moreover, animals are taking advantage of the limited human activity, and they have started roaming empty streets and waterways. Kangaroos have been spotted in city streets in Australia, and goats have been seen at crosswalks in Wales. A herd of goats has taken over a deserted town centre, eating hedges and flowers from gardens!


Fortunately for people and unfortunately for nature – quarantine due to the coronavirus will one day end, which means that the state of air pollution will return to its tragic norm. We need to take care of our environment, because without much human influence on it – it immediately changes for the better and it should give us food for thought. The air is cleaner but unfortunately it won’t last forever.
