Eva Longoria is one of the celebrities who help spread awareness on teenage pregnancy, one of the major social issues worldwide.

In the documentary which aired on PBS on February 2, Longoria's travel to the slums of Cartagena, Colombia was featured, as she looked into the problems of teenage pregnancy, according to a report from The Hollywood Reporter.

The documentary is a part of the in-depth study titled "A Path Appears," which will feature Pulitzer Prize winners Nicholas Kristof and Sheryl WuDunn, Malin Akerman, Mia Farrow, Ronan Farrow, Jennifer Garner, Regina Hall, Ashley Judd, Blake Lively, Alfre Woodard and Longoria to Haiti, Kenya, Colombia and across the United States "to explore the effects of gender inequality and poverty and will meet with local activists in the respective cities and countries," The Hollywood Reporter noted.

"Being in the slums and walking from barrio to barrio, you can't walk two steps without seeing a pregnant teen," Longoria was quoted by the news outlet as saying.

The actress and activist added in the video clip, "I didn't know there were so many pregnant teens here in Colombia. I definitely don't think [the pregnant teens] are aware that there's a life outside of the bubble they live in, which is poverty. They don't believe that they could go study."

The documentary was helmed by executive producers Maro Chermayeff, Jeff Dupre, Jamie Gordon, and Mira Chang. Chermayeff is also in the director's chair, with Joshua Bennett as the series producer, The Hollywood Reported continued.

The three-part series will air for three consecutive Mondays -- Jan. 26, Feb. 2 and Feb. 9 -- from 7-8:30 PM PT/10-11:30 PM ET on PBS, The Hollywood Reporter said.

According to Fox News Latino, Longoria examined the work of the Juan Felipe Gomez Escobar Foundation in Colombia, particularly its "medical assistance, psychological counseling, and job training." The charity reportedly aims to help marginalized teenage moms and children suffering from health problems. Pregnant girls as young as 12 years old come to the foundation to seek help. Others were even prostitutes at some point.

"What I love about documentaries is it humanizes issues. When you put a face to the problem, now all of a sudden you're invested. You're invested in this person's story and their life's journey," the actress further explained to The Hollywood Reporter.

The documentary is based on a book by Kristof and WuDunn titled "A Path Appears: Transforming Lives, Creating Opportunity," which revolves around "the cruelest kinds of gender oppression including child slavery and human rights violations," Fox News Latino explained.
