Climbing Everest, I've proved a tribal girl can do something: Malavath Poorna

At just 13 years, Malavath Poorna from Telangana has become the youngest female climber in the world to scale Mount Everest. Speaking with Rohit E David, Poorna discussed how she has emerged from a family of agricultural labourers to become a mountaineer, the difficulties she faced while navigating Mount Everest, the one thought that kept her going — and how she wants to climb many more mountains now.
