Miley Cyrus is taking to YouTube to send a message to her fans: It's easy being green.

In the latest installment of her YouTube series with BFF Mandy Jiroux, Cyrus, 15, encourages viewers to take care of the environment through her new song, "Wake Up America."

The pair offer some teen-friendly tips in the video, suggesting that viewers unplug their cell phones, give old magazines to friends instead of trashing them, and shop online to save gas.

The PSA also serves as a bonus music video for her new single as Cyrus breaks into song: "Oh, can you take care of her?/Oh, maybe you can spare her/Several moments of your consideration/Leading up to the final destination."
