CNN's Anderson Cooper reveals this year's top 10 CNN Heroes:
Dale Beatty (Statesville, NC) After Dale Beatty lost his legs in the Iraq War, his community thanked him for his service by helping him build a home. To pay it forward, Beatty co-founded Purple Heart Homes. Since 2008, the nonprofit has modified or helped provide homes for dozens of disabled veterans.
Georges Bwelle (Yaoundé, Cameroon) For decades, Georges Bwelle watched his father suffer, unable to get the medical attention he needed. Now a doctor himself, Bwelle travels into the jungles of his native Cameroon nearly every weekend, providing free surgery for those who don't have access to health care.
Robin Emmons (Charlotte, NC) More than 72,000 people in Charlotte, North Carolina lack access to fresh produce. When Robin Emmons discovered this problem, she turned her backyard into a garden. Since 2008, she has grown more than 26,000 pounds of fruits and vegetables for area residents.
Danielle Gletow (Trenton, NJ) Danielle Gletow started One Simple Wish, a nonprofit that helps grant the wishes of foster children. Wishes are posted online, and anyone can pay to make a child's wish come true. Since 2008, the group has helped grant more than 6,500 wishes to children in 42 states.
Tawanda Jones (Camden, NJ) Tawanda Jones is using dance to empower the youth of Camden, New Jersey, one of the poorest cities in the country. Through Jones' drill team program, more than 4,000 children have learned discipline, respect and community service - and all of them have graduated high school.
Richard Nares (San Diego, CA) Richard Nares lost his son to leukemia in 2000. Today, his nonprofit, the Emilio Nares Foundation, provides transportation and support for low-income children battling cancer in San Diego. The group gives more than 2,500 free rides each year.
Kakenya Ntaiya (Enoosaen, Kenya) Kakenya Ntaiya is inspiring change in her native Kenyan village. After becoming the first woman in the village to attend college in the United States, she returned to open the village's first primary school for girls. Today, Ntaiya helps provide an education - and much more - to 155 girls.
Chad Pregracke (East Moline, IL) Chad Pregracke has made it his life's work to clean up the Mississippi River and other American waterways. Since 1998, about 70,000 volunteers have helped Pregracke and his nonprofit remove more than seven million pounds of garbage from 22 rivers across the country.
Estella Pyfrom (West Palm Beach, FL) Estella Pyfrom used her life savings to create "Estella's Brilliant Bus," a mobile computer lab that provides digital access and tutoring for low-income children and adults in Palm Beach County. Since 2011, thousands of students have benefited from her bus.
Laura Stachel (Berkeley, CA) Dr. Laura Stachel co-founded We Care Solar to provide a simple, reliable light and power source to health-care facilities in developing countries. Since 2009, more than 250 "solar suitcases" have been helping to save mothers' and babies' lives in more than 20 countries.
All the top 10 Heroes were nominated by CNN's global audience and profiled earlier this year on CNN. Each will receive $50,000 and be honored at "CNN Heroes: An All-Star Tribute," a globally broadcast event that airs December 1.
One of the top 10 will receive an additional $250,000 for their cause if the public chooses them as the CNN Hero of the Year.
Starting Thursday morning, you will be able to vote for your favorite Hero at CNNHeroes.com or from your mobile device. Voting ends November 17.
Last year's Hero of the Year was Pushpa Basnet, a Nepalese woman who supports children so they don't have to live behind bars with their incarcerated parents.
