Apparently, The Muppets had this whole 'going green' thing down years before it became hip.
I stumbled upon this PSA (below) from the 1980s starring Kermit the Frog and Fozzie Bear preaching about "using our water wisely" by keeping our waters clean and debris-free.
If puppets can get on the 'green train', then why shouldn't people do the same?
