She may fight to the death on-screen in The Hunger Games, but in reality, actress Jennifer Lawrence prefers saving lives. When a woman walking a dog collapsed outside Lawrence's apartment earlier this week, she rushed outside to help. Lawrence called for paramedics and, once the woman was reported to be okay, helped untangle the woman's dog caught in its own leash.

As a tribute to Katniss Jennifer's heroism, we've rounded up 8 other inspiring young people who made the news for selfless actions this year, from an Australian teen who saved three lives in three years, to a 17-year-old who drove a bus full of students to safety. Click through the slideshow below to read about them.
