After the city was closed, Venice's dirty rivers became very clear. How big is the impact of human activities on the environment?

I think we can see how much damage people have done to the environment after the closure of the city through Venice.

Venice is a very famous water city in Italy, known as? A city in the forest? Venice was beautiful a long time ago, but with the progress of society and the development of the times, more and more ships appeared in the rivers of Venice. These changes have caused great damage to the environment in Venice. The water in Venice began to become turbid. There were no fish in the water, no sky and no dolphins in the bay. It is not as beautiful as before, but everything has changed since it broke out.

This epidemic is raging in Europe, especially Italy, which is the hardest hit area in Europe. 10 days ago, the Italian government announced the closure of cities across the country. After the national city was closed, people were surprised to find that Venice had changed, the water had become clear, and no fish could be seen before. Now you can see fish swimming in the water at a glance, swans and dolphins are back, and they have become frequent visitors to Venice again. Great changes have taken place in Venice because of this epidemic.

I think this change in Venice is very touching. Because of the epidemic, the city has changed back to its original appearance. There are not so many ships passing by and there are not so many tourists. This small town has only the beauty of residents and these animals, but this beauty will not last long. When the epidemic is over, this town will become the same as before, with heavy traffic, no animals and no fish. Maybe there will be no city in a few hundred years, because of the global climate.

To sum up, we can get a glimpse of our impact on the environment through Venice, even in a small city like Venice, not to mention those big cities. Our damage to the environment is really too serious. I hope we can protect our environment in the future. After all, we need them to survive.
