While Earth Day turns 40 today, for me it's about 19 years old.  Here are some old Earth Day videos I remember from growing up:

Here's one I actually remember from my first Earth Day.  I don't know if it aired nationally but I remember it here on our local stations in NH:

This one with Downtown Julie Brown and Egon is great:

Sorry Auntie Litter but this one is a little embarrassing (as are any attempts by old white people to reach the youth by rapping):

Now these two are not specific "Earth Day" videos, but they are probably the most iconic Environmental Ads of all time.  Who can forget the crying Indian?

Happy Earth Day!
