Do not open the Pandora's box again and again

We tend to think of the spread of viruses as a human disaster. We're always trying to exterminate viruses, to compete with viruses in the match of evolution. Yet viruses have existed in the world long before humans did. Perhaps humans are the true "virus" for earth. The outbreak of COVID-19 is actually the earth's warning to mankind and the revenge for mankind's repeated offence and destruction of natural balance. The way for human beings to get along with viruses is to strike a balance. Do not open the Pandora's box again and again.
