"Pad Yatra: A Green Oddyssey" documents the adventure of 700 people trekking across the Himalayas with a call to save the planet's "3rd. pole" - a glacial region devastated by the effects of climate change and garbage. Walking from village to village across the most treacherous terrain on earth, the trekkers spread their message of ecological compassion and emerge with a half ton of plastic litter strapped to their backs. This trailer gives a glimpse of the trek that triggered a historic green revolution across the rooftop of the world.
