Airline emissions have also dropped dramatically around the world. In the first three months of 2020, 68 million fewer passengers traveled by air than in the first three months of the previous year. As a result, the skies are becoming more blue.

We have to protect the environment and the fauna for our own benefit. Otherwise, nature will come up with all such horrible teachings that humanity will be endangered. Then the last will not be saved.
