Mick Jagger and Keith Richards are helping their kids raise money for charity.

Jagger’s son Jimmy and Richards’ daughter Alexandra both serve on the board of Project Zero, which aims to protect the oceans.

We hear the two rockers helped out by posting on social media that they’d adopted 1 square kilometer of an ocean as part of the fund-raiser.

Claudia Schiffer, Gabrielle Reece and Laird Hamilton also helped raise more than $50,000.
