(CNN) -- In Colombia, one in five girls age 15-19 is or has been pregnant, nearly triple the U.S. rate.
And in the city of Cartagena, where one-third of residents live in extreme poverty, many of these young moms don't have a chance to improve their lives.
But Catalina Escobar is working to change that through her foundation and its teen mothers program. Her group aims to teach young women how to support themselves and their children, and since 2002, Escobar has helped empower more than 2,000 teen moms.
CNN asked Escobar for her thoughts on being chosen as one of the top 10 CNN Heroes of 2012.
CNN: What do you hope this recognition will mean to the Juan Felipe Gomez Escobar Foundation?
Catalina Escobar: This award means a great deal to me and to the foundation. It is the most effective and quickest way to tell everyone around the globe that in Colombia, we can do serious philanthropy, where our models really work to make social transformations.

Pushpa Basnet was shocked to learn that children in Nepal were living in prisons with their parents. In 2005, she started a children's center that has provided housing, education and medical care to more than 140 children of incarcerated parents. "I always had a dream to build our own home for these children, and I want to rescue more children who are still in prisons," Basnet said.

Wanda Butts lost her son in a drowning accident six years ago. In his memory, she started the Josh Project, a nonprofit that taught nearly 1,200 children -- most of them minorities -- how to swim.

Mary Cortani is a former Army dog trainer who started Operation Freedom Paws, a nonprofit that helps war veterans train their own service dogs. Since 2010, she has worked with more than 80 veterans who have invisible wounds such as post-traumatic stress disorder. "I'm hoping this brings awareness to the world that PTSD is real and that we will be able to reach more veterans who so desperately need help," Cortani said. See more photos of Mary Cortani
Catalina Escobar is helping young moms in Colombia, where one in five girls age 15-19 is or has been pregnant. Since 2002, her foundation has provided counseling, education and job training to more than 2,000 teenage mothers. "Teenage pregnancy is a world poverty problem, and we have developed models of intervention that break the cycle," Escobar said. "I want to share it with people around the world."

Razia Jan is fighting to educate girls in rural Afghanistan, where terrorists will stop at nothing to keep them from learning. She and her team at the Zabuli Education Center are providing a free education to about 350 girls, many of whom wouldn't normally have access to school. "This honor is a God-given gift that will make it possible for me to continue to give a ray of hope to these girls," Jan said. "My goal is to break the cycle of violence."

Thulani Madondo struggled as a child growing up in the slums of Kliptown, South Africa.

In memory of his daughter who was killed by a drunken driver in 2007, Leo McCarthy started Mariah's Challenge. The nonprofit gives college scholarships to teenagers who pledge not to drink while they're underage. Nearly $150,000 in scholarship money has been awarded. "We can change an apathetic culture of teenage drinking and driving," McCarthy said. "Hopefully one day soon we will not need Mariah's Challenge." See more photos of Leo McCarthy
Connie Siskowski is helping young people who have to take care of an ill, disabled or aging family member. Since 2006, her nonprofit has provided assistance to more than 550 young caregivers in Palm Beach County, Florida. "I can only believe that when more people understand about this precious population, they, too, will want to recognize and support them," Siskowski said. "These children suffer silently behind closed doors." See more photos of Connie Siskowski
After beating his addiction to drugs and alcohol, Scott Strode found support through sports. Since 2007, his nonprofit, Phoenix Multisport, has provided free athletic activities and a sober support community to more than 6,000 participants in Colorado. "This is an opportunity to shine a light on individual stories of recovery and sobriety in a way that will help remove the shame and stigma that surrounds dependency and addiction," he said.

Malya Villard-Appolon is a rape survivor dedicated to supporting victims of sexual violence in Haiti. In 2004, she co-founded KOFAVIV, an organization that has helped more than 4,000 rape survivors find safety, psychological support and/or legal aid. "This encourages me to continue to fight on behalf of women and girls who are victims," she said. "I hope it brings about a change for my country." See more photos of Malya Villard-Appolon

The top 10 Heroes: In their own words
En espanol: Catalina Escobar
But we also want to show that in a little corner of Colombia, there is a great social inequality and despair like happens in India, Africa or Haiti.
This recognition also tells me: "Keep on going, never stop. You´re doing well!" When you work in this field, you have to be a bit crazy -- or crazy enough to devote yourself entirely to humanity. That´s what I love.
CNN: What was your reaction to the news that you'd been selected as a top 10 CNN Hero?
Escobar: I was really surprised because all the Heroes do great jobs in all areas. When I knew I was selected ... my eyes opened wide, and since then, I haven't stopped smiling!
For me, it has been really an interesting journey working with the foundation, which last year celebrated its 10th anniversary. When you work in this field, you never expect to get recognition. You only work day and night to change people's realities, especially when they are in extreme poverty.
But knowing that I am in the top 10 CNN Heroes, it's been amazing news, not only for myself, but also for the foundation, its employees and all the people we have worked with. ...
Our team felt so proud of their work, since it has been a constant, hard and persistent labor during so many years. For our supporters, the feeling has been of a national pride. ... What this shows is that there is a will to continue working for the vulnerable community in the slums of Cartagena, and keep working with us.
Who's your CNN Hero of the Year? Cast your vote!
CNN: How will you use the $50,000 award that you receive for being selected as a top 10 CNN Hero?
Escobar: It will be invested in the foundation's programs. We provide counseling, education and job training to hundreds of teenage mothers. It will also go to our work tending to the infants of the teen moms at the day care center.
We also have a medical center, and there are so many vulnerable women that are coming to the center for special services that they can't get elsewhere. Not all of them can pay, so we want to invest in them as well.
CNN: What do you want people to know most about your work?
Escobar: The important thing is to show that our models of intervention are sustainable in the long run. They're also replicable in areas having the same social conditions, and the results are measurable.
Above all, this is just the beginning!
