Virunga is Africa’s oldest national park, a UNESCO world heritage site, and the last natural habitat for the endangered mountain gorilla. None of that will stop the business interests and rebel insurgencies lurking at the park’s doorstep. Orlando von Einsiedel pairs gorgeous natural scenes from Virunga with riveting footage of the Congolese crisis, raising an ardent call for conservation as a vital human enterprise. Along the way, he spotlights the incredibly dangerous work that is often required to safeguard the environment. [Synopsis courtesy of Tribeca Film Festival]
