Reading Rainbow started in 1983 and ran for 21 seasons. It focused on a theme from a book each episode, with the show's host LeVar Burton often going to visit someone at their workplace, in keeping with the theme. As many of the children's books involved nature in some way, the themes covered were often green. In this episode, Burton follows a beekeeper at work-- check out the awesome bee rap/montage that kicks in at the 3:30 mark.
This is a great video. I forgot about Burton pre Star Trek and his kid shows....
He also played young Kunta Kinte in the "Roots" saga.
