Disney Parks shared this video that includes Caroline Sunshine on their YouTube account today (April 24, 2013).
Celebrate Earth Month by visiting a national park! Disney Friends for Change – a program that inspires kids and families to make a positive impact by helping people and the planet – developed this PSA that will air on Disney Channel and Disney Online.
Note: I believe this video came out last year. I remember seeing it on Caroline’s website. After checking it out – the video is no longer there.
