Understanding that overfishing is a serious problem in today's world -- and that the easiest way to raise awareness for a cause is to convince pretty girls to take off their clothes in support of it -- Mick Jagger's 28-year-old daughter Lizzy has taken it all off for Fishlove.

As Buzzfeed reports, the young Jagger is one of several celebrities -- including actress Greta Schacchi, director Terry Gilliam, and Lizzy's mom Jerry Hall -- to pose nude with fish as part of "an ongoing photographic project that invites well-known personalities across the globe to make a bold stand to stop over-fishing."

It might seem a little frivolous, but the cause is actually deadly serious. "Scientists predict that all marine life will effectively disappear from our oceans by the middle of this century if nothing is done about over-fishing," warns the Fishlove website, pointing out that "All the fish taken in these photographs have been kindly donated by Waitrose, and have been caught sustainably according to the company’s impeccable environmental policy."
