David E. Simpson’s documentary about African wildlife conservation lacks the sort of personal drama one now associates with its production company, Kartemquin (Stevie, Hoop Dreams), but it raises some interesting issues about the coexistence of people and wild animals. Traveling to Kenya and Namibia, Simpson looks at indigenous communities that are trying to transition from cattle-based economies, which they defended from predators by poaching, to community-based conservation, which theoretically allows them to sustain themselves while also preserving endangered species. 85 min.
