An environmental documentary following intrepid filmmaker Kip Andersen as he uncovers the most destructive industry facing the planet today – and investigates why the world’s leading environmental organizations are too afraid to talk about it. Animal agriculture is the leading cause of deforestation, water consumption and pollution, is responsible for more greenhouse gases than the transportation industry, and is a primary driver of rainforest destruction, species extinction, habitat loss, topsoil erosion, ocean “dead zones,” and virtually every other environmental ill. Yet it goes on, almost entirely unchallenged. As Andersen approaches leaders in the environmental movement, he increasingly uncovers what appears to be an intentional refusal to discuss the issue of animal agriculture, while industry whistleblowers and watchdogs warn him of the risks to his freedom and even his life if he dares to persist. Eye-opening and inspiring, this shocking yet humorous documentary reveals the absolutely devastating environmental impact large-scale factory farming has on our planet, and offers a path to global sustainability for a growing population.

The iconic statues and sensationalized "mysteries" of Easter Island (Rapa Nui) have drawn the interest of the world for centuries, attracting curious visitors to its shores. Today, this tiny, barren island is experiencing an economic boon as tourism skyrockets. Yet the indigenous culture and the island's fragile environment are suffering.

Crafted as a story passed down to his newborn son, Sergio intertwines the authentic history of the island with the stories of four islanders. In their own voices, these Rapanui reveal the reality of modern life and the actions they are taking to preserve their culture and environment amidst rapid development. A local ecologist leads recycling efforts to tackle the mounting trash arriving with tourists and the waves of plastic washing up on shore.
