(CNN) -- For their extraordinary efforts to help change the world and better the lives of others, 10 everyday people will receive $50,000 and a chance for much more. This select group -- the top 10 CNN Heroes of 2012 -- was revealed Thursday.
All the top 10 were nominated by CNN's global audience and profiled earlier this year on CNN. They will be honored at "CNN Heroes: An All-Star Tribute," a globally broadcast event that airs live December 2 at 9 p.m. ET/6 p.m. PT.
At the tribute show, hosted by Anderson Cooper in Los Angeles, one of the top 10 will be named CNN Hero of the Year and receive an additional $250,000 to continue their work.
The Hero of the Year is decided by a public vote. Through November 28, you can vote for your favorite Hero at CNNHeroes.com or from your mobile device.
This is the sixth year CNN has conducted its annual search for CNN Heroes. In those years, the campaign has profiled more than 180 people on CNN and CNN.com.
Here are the top 10 Heroes of 2012, in alphabetical order:
