Earth Day

So I didn't know today was Earth Day until this morning and now it seems like Earth Day is EVERYWHERE I look. I don't remember Earth Day being that big a deal in the past. In elementary school they made us go out and clean up the playground or plant flowers and offhandly mention that it was Earth day but really I think they just wanted us to do the work for the janitor. Come to think of it I think that janitor may have been really lazy because if you got detention then you would have to go around and clean all of the classrooms. Hmmmm. Anyway back to my point is it just me or is Earth Day a bigger deal this year then it has been in recent years? I don't really have anything else to say today so I'll probably have a longer post tomorrow.
P.S. Is Earth Day supposed to be capitalized? I think it is and everywhere I see it written out it is but I just wanted to check.
