As a practicing Buddhist, doing my best to uphold the First Precept, I am disturbed by the scorched earth strategy that authorities are taking towards disinfecting every last surface with which humans might come into contact in the pursuit of eradicating Covid-19. I have seen images of crews in cities in Asia, for instance, who are spraying down everything in sight with disinfectant, killing every last thing in their path. In many places around the world workers have been employed to wipe down surfaces with disinfectant on a regular basis.
All around us there are millions of microscopic organisms, many of which are beneficial to each other and to humans. The human body itself is full of beneficial bacteria that aid in digestion. All of the disinfecting going on with the aim of eradicating Covid-19 is wiping out entire microscopic ecosystems.
I get that all manner of human activity threatens the existence of the microbiome around us. This conversation has come up before in this forum with regards to the debate over whether the First Precept requires a vegan diet. Tilling the land to grow crops disturbs the world of microscopic organisms. So obviously, human existence (or the existence of any animate species, for that matter) comes at the expense of other living beings (a horse swatting a fly can kill the fly). But there is something unsettling about the indiscriminate mass disinfecting campaign in response to Covid-19 that seems so at odds with the Noble Eightfold Path.
Edit: It also is rather disturbing, and rather un-Buddhist-like, the way that captive species were kept in wildlife markets in China which allowed the Covid-19 virus to spread from one species to another, in ways that would not have occurred in nature.
