In our days, Covid-19 spread in the world and caused a lot of damage for the humanity. More than 141 M people were contaminated and 3m were dead due to this virus. So if I ask you :"what do you think about this virus?" you will absolutly say: "It is just a curse from God to punish us for our greed !". But if we really think about it, we will find that the corona virus has many environmantal effects.
-Today, let's talk about its advantages. The global disruption caused by this virus has brought about several effects on the environment and climate.
- 1- Reduction of air pollution:
*The Covid-19 has spread in the world and day by day it becomes stronger and faster. So to make a limit to this frightening spread, all the countries around the world advertise a compolsory lockdown. So, citizens were obliged to stay home by the law. they can't go to work, go to study or even go outside to play. you can't get out of your house. You have just the right to go out to buy food just when it's necessary. As result, in Tunisia for exemple, the use of the car became rare or even unnecessary. And all of us know that cars release CO2 wich is one of the most dangerous gaz who cause the rupture of the ozone layer. So when we stopped using cars, the proportion of CO2 and air pollution in general decrease. In America for example, Compared with this time of last year, levels of air pollution in New York has reduced by nearly 50% because of measures taken to control this virus. In the same way, in China, due to the lockdown of all the heavy industries, it was declared that nearly 50% reduction of N2O and CO occurred. Some studies say that if the shutdown will continue, the ozon layer will health and that's good news for us in this hard situation.
- 2-Reduction of water pollution:
In our days, water polution is one of the biggest problems in the world. In some developing countries such as India drinkable water become rare because of the irresponsable actions of the people. They throw all their domestic and industrial wastes in rivers without caring about the fish. Some studies say that 100 millions marin animals die each year because of the plastic wastes. But after the lockdown, water polution decreased and rivers become cleaner. For example, the river Ganga and Yamuna have reached a significant level of purity due to the absence of industrial pollution on the days of lockdown in India wich is a really good sign of an improvement in the situation.
All in all, the Covid-19 has many advantages that a lot a us doesn't know. And in my opinion we should deeply think whether the Covid-19 was a curse or a blessing?
