Happy Earth Day! Music for the day...

Happy Earth Day everyone!  Hope everyone is safe and healthy.  Here is some music for the day:


Keeping with the theme, what's your song of the day?
I remember being in middle school for the original nationwide "environmental teach-in" on April 22, 1970, or the first Earth Day.  I seem to remember watching a movie on ecological threats in the gymnasium with the accompanying music being Marvin Gaye's  "Mercy Mercy Me (The Ecology)."  However, I believe that song/album came out the following year in 1971 so the assembly I am remembering must have been from the second or third Earth Day.
Gotta be The Beach Boys "Surf's Up", "Don't Go Near The Water", and Sail On, Sailor".
Speaking of Earth, tonight I watched The Planet Of The Humans on You Tube. Fact-filled fun for the whole family! ;-)
