Facebook is hoping to use peer pressure to convince users of the social network 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. Users living in the two countries 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. "Getting people to donate their organs has been an intractable public health problem," Dr. Andrew M. Cameron, a transplant surgeon at John Hopkins Hospital in Baltimore, said in a statement. "If we succeed on Facebook with organ donation, it could be a model for how to use of-the-moment social media to solve important medical issues.”

Every day an average of 18 Americans die while waiting for a life-saving transplant, while another 79 people receive a new transplant during the same time, according to the U.S. Department of Health and Human Services. There are currently more than 100 million people in the U.S. who have agreed to be organ donors.

Posting Your Organ Donor Status On Timeline

If you want to post your organ donor status to your profile navigate to your Facebook Timeline and select "Life Event" from the status update box. In the drop down menu that appears select Health & Wellness and then "Organ Donor...". You will then see a pop-up window where you can enter your organ donor status, when you became an organ donor, and even share a story about why you chose to become an organ donor.

Facebook's goal to help solve the problem of organ donation is laudable, but to be effective users will have to embrace the idea of sharing information that some may see as incredibly personal. But organ donation may also be the ultimate form of so-called slacktivism that many critics say is popular among the social network's users.

Slacktivism is when someone participates in an activist cause by doing nothing more than signing a petition or creating a status update drawing attention to a critical issue. The move costs you almost nothing in terms of effort, but can provide a warm, fuzzy feeling for having "stood up" for a cause. Registering as an organ donor fits perfectly into this model since all you have to do is register your name online and then post an update to your Facebook Timeline. Then, in the unlikely event that you die in an accident or other situation that leaves your organs in good condition, your body parts may help save another person's life.

The idea to add your organ donor status to Facebook appears to the be the brainchild of Facebook COO Sheryl Sandberg and Dr. Cameron. The pair were at Harvard together and came up with the idea after meeting at a college reunion last spring, according to a John Hopkins press release. Facebook CEO Mark Zuckerberg early Tuesday told Good Morning America his girlfriend, Priscilla Chan, who is studying to be a pediatrician, was also an inspiration.
