Pakistan climber cleanses K2 as shrine to fallen father

When Sajid Ali Sadpara gazes at K2, Earth's second tallest mountain, he sees his father's final resting place, but also a blight of litter discarded by climbers.

Over the course of a week, Sadpara and his team cleared some 200 kilograms of trash from the mountain, one of Earth's most unforgiving environments.
