Our Planet — Benchmark Visuals and Global Scope
Produced by Silverback Films for Netflix in partnership with WWF, Our Planet is the closest thing modern television has to a definitive survey of Earth’s remaining wild places. Eight episodes cover frozen worlds, jungles, coastal seas, fresh water, and the high seas. Sir David Attenborough narrates with his characteristic authority, and the series does not shy away from documenting what is being lost. The accompanying book and website extend the content significantly for those who want to go deeper.
Blue Planet II — Definitive Ocean Documentary
Blue Planet II spent four years in production and visited every ocean on Earth. The series introduced mainstream audiences to deep-sea ecosystems that had rarely been filmed before, including bioluminescent creatures and the impact of plastic pollution on marine life. The final episode, Our Blue Planet, addresses the human threats facing ocean environments directly. It remains one of the most technically ambitious documentary series ever made and the ocean sequences in particular set a standard that has not been surpassed.
Seaspiracy — A Different Kind of Conservation Film
Seaspiracy sparked substantial debate when it released on Netflix in 2021, and that debate is part of its value. Filmmaker Ali Tabrizi investigates the industrial fishing industry, ocean plastic attribution, and the sustainability claims made by major seafood certification programs. Some scientists disputed specific statistics, and those critiques are worth reading alongside the film. Taken as a starting point for examining fishing industry practices rather than a final word, it is one of the most provocative conservation films of recent years.

Before the Flood — Climate Change Made Personal
Directed by Fisher Stevens and featuring Leonardo DiCaprio, Before the Flood travels to the Arctic, the Amazon, India, China, and Pacific island nations threatened by sea level rise. Its strength is in making abstract climate data feel immediate and human. DiCaprio’s conversations with scientists, politicians, and community leaders create a coherent picture of why action has been slow and what needs to change. Available for free on multiple platforms, making it one of the most accessible films on this list.

My Octopus Teacher — Intimate and Unexpected
My Octopus Teacher won the 2021 Academy Award for Best Documentary Feature for good reason. Filmmaker Craig Foster spent a year free-diving daily in a South African kelp forest and documenting his relationship with a single octopus. The film is less about conservation statistics and more about what happens when a human slows down and pays deep attention to a non-human life. The result is a meditation on connection, attention, and loss that reaches viewers who might not respond to more data-driven conservation films.

How to Choose Conservation Documentaries
Consider your goal before choosing. If you want the broadest introduction to multiple ecosystems, Our Planet or Blue Planet II are the right starting points. If you want to focus on a specific issue like ocean fishing or climate policy, Seaspiracy and Before the Flood are more targeted. For something personal and emotionally resonant rather than survey-level, My Octopus Teacher stands apart. Pairing a documentary with follow-up reading from the organizations mentioned in each film significantly deepens the impact.
