This was actually the first commercial I really remember watching as a child and I remember it well because William Conrad's deep voice really scared me! It was this special voice that made Conrad a legend in radio where he appeared on over seven thousand shows, in fact he was the original Matt Dillon when Gunsmoke began on the radio. In addition, Conrad also narrated The Fugitive and Rocky And Bullwinkle cartoon show (he also starred on Cannon and Jake And The Fat Man). Pollution is an issue that affects all of us and it is still a problem today. Iron Eye's Cody's tear when that garbage is thrown at his feet is worth a thousand words.
