Doing her part to prevent wildlife abuse, January Jones appears in a new Public Service Announcement on behalf of great white sharks.

The “Mad Men” starlet teamed with ocean conservation organization Oceana for the spot, urging viewers to stand up against shark extinction.

Jones explains, “Healthy oceans need sharks. But great whites are in danger of extinction. Please help before it’s too late.”

And with Shark Week going on over at the Discovery Channel, now is a great time to “be scared FOR sharks,” not of sharks.
