NOW | Environmentalist Conrad Anker

Two men on a remarkable journey high in the Himalayas investigate threats to global water and food supply. Next on NOW.

On Friday, March 12, at 8:30 PM (EST) (check local listings), David Brancaccio and environmentalist Conrad Anker – one of the world’s leading high-altitude climbers – trek to the Gangotri Glacier in the Himalayan Mountains, the source of the Ganges River, to witness the great melt and its dire consequences firsthand. The two also visit Montana’s Glacier National Park to see the striking effects of global warming closer to home and learn how melting glaciers across the world can have a direct impact on food prices in the US.

Along the way, Brancaccio and Anker bathe in the River Ganges, view a water-shortage calamity in India, and see with their own eyes and cameras the tangible costs of climate change.

“We can’t take climate change and put it on the back burner,” warns Anker. “If we don’t address climate change, we won’t be around as humans.”
