Have you noticed...?

On my way home from the office the other day I was reminded that over the last couple of weeks the sky is a startling blue and the clouds are amazing. Have you noticed this, too? One night last week my wife and I were on one of our after-dinner walks in the neighborhood. After we got back we just were in awe at how bright the stars were. I've heard that the waters in Venice are clear and haven't been that way in years! Does it take a worldwide pandemic to clean up our environment?
