Thanks for the thoughtful comment @juanvegetarian!

Interesting point you make; just a couple of weeks back I wrote a post about the way pollution has become lower, thanks to the many shut-downs and quarantines... and made the point that Covid-19 is often an illness that affects the lungs. Without Humans to pollute the world, our planet can BREATHE again, and in an interesting stroke of Karma, what's enabling that cleansing is a things that makes it difficult for us humans to breathe. Interesting "symmetry," I think.
