Documentary films have the power to shape how we understand nature. They offer a deeper look into the planet's challenges, bringing people together through shared experiences and inspiring action. As a media partner for the 2026 Environmental Film Festival in the Nation’s Capital (DCEFF), Mongabay is featuring exclusive insights into some of this year’s standout documentaries. From Indigenous land defenders in the Amazon and the glowing mysteries of deep-sea bioluminescence, to updates on youth activists jailed for standing up for Cambodia's environment, these films explore the frontlines of conservation and environmental justice. Through these stories, Mongabay examines the research, storytelling and courage that bring these issues to life. DCEFF runs from March 19-28 in Washington, D.C.
