I think, COVID-19 has changed our lives to both good and bad in some way. Moving of vehicles is less than ever before, factories work part time and don’t work relentlessly. So they produce carbon dioxide less than before and Green house gases are no much high as they used to be. As well as global warming is decreasing and we can see that plants that they were destroyed are growing again. At the same time we have been witnessing dead of a lot of people unfortunately. People's interacting has reduced and on top of this, whatever we did in order to have pleasant time decreases. I think, we would have appreciated our friends, family and everything that made us be happy if we had known COVID-19 is going to separate us. In conclusion, although our lives are changed by COVID-19 but we should cope with it until finding a way to permanent treatment of COVID-19.
