Looking for an ideal way to celebrate Earth Day? For The Kiddos, it would have to be spending it outside spending some time in this beautiful Creation we inhabit. (Outdoor programs we're looking forward to this Spring are listed here and here.) With that kind of celebrating, I think they'd have no complaints about turning it into Earth Week.
I'm guessing that's why the folks at the Center for SCREEN-TIME Awareness always plan their TV Turnoff Week to include Earth Day-- this year (their 14th!) TV Turnoff Week is April 21 to 27.
Besides dragging your kids outside, if you've got other great ways to help preschoolers break the TV habit, I'd love to hear them!
