Captain Planet and the Planeteers 2x14

Gi and Linka are livid when Wheeler belittles their favorite rock singer, but it looks as though Wheeler may be right after they come upon a land-ravaging, strip-mining operation run by Hoggish Greedly, but bankrolled by none other than their idol - Sky Runner! Stunned, they confront the star, who turns out to be innocent, but they still have to stop Greedly before the small mining town is destroyed.
