For 28-year-old TRIP JENNINGS, it's not that filming paddling expeditions in Papua New Guinea or first descents on the Congo River got old, but rather that the environmental devastation he witnessed began to matter more. His most recent short documentary, Flathead Wild, is about how one of the most intact ecosystems in North America, British Columbia's Flathead River, is being threatened by a large-scale mining project. "I wanted people to see that this place is beautiful and special," says the expedition kayaker and co-founder of multimedia company Epicocity Project. "I wanted them to feel what it would be like to lose it." So far his plan is working. In February, British Columbia and Montana signed a "Memorandum of Understanding and Cooperation" to retire all mining claims in the area. Next up: an investigative documentary about elephant poaching in the Democratic Republic of the Congo.
