Facebook CEO Mark Zuckerberg is hoping to use the power of his 900 million member social networking platform and peer pressure to convince people to become registered organ donors. Starting Tuesday, Facebook users living in the U.S. and U.K. can add an organ donor status to their Facebook profile and post it publicly to their Timeline.

Zuckerberg says the inspiration behind Facebook's organ donation push comes from COO Sheryl Sandberg and Dr. Andrew M. Cameron, a transplant surgeon at John Hopkins Hospital in Baltimore. Zuckerberg attended Harvard with Sandberg and together came up with the idea after meeting at a college reunion last spring, according to a John Hopkins press release. Zuckerberg early Tuesday told the ABC new program Good Morning America his girlfriend, Priscilla Chan, who is studying to be a pediatrician, was also an inspiration.

Users living in the U.S. and U.K. that want to become donors can use the new feature to sign-up with their respective organ donor registries. Facebook's announcement follows reports from late Monday that the social network was getting ready to release a new life-saving tool.

If successful, Facebook's organ donor push has the potential to help save the lives of the more than 114,000 people in the U.S. currently waiting for new kidneys, lungs, hearts, and other organs. Read more at PC World
