In a new PSA, debuting on UsMagazine.com, Oscar-wining actress Sandra Bullock urges fans to help out in the Gulf oil spill crisis.
Bullock, 45, is featured alongside Blake Lively, Lenny Kravitz and Dave Matthews (among others) in the clip for Restore the Gulf, a grassroots initiative to secure long-term funding to restore and protect the Gulf Coast and area wetlands.
The clip is designed to capture signatures to an online petition to be delivered to Congress.
"What can you offer?" Bullock asks in the clip (see above). "Your voice. Speak up!"
