Natural Heroes is a series of independently produced films that share a common theme: people who are actively involved in improving the environment, whether in their local community or on the other side of the world.

The series is the result of a multi-year partnership between KRCB-TV, a Bay area public television station, and GreenTreks Network, a Philadelphia-based nonprofit communications group whose mission is "telling stories that change the world." Their shared vision of programming that inspires optimism and involvement led to the creation of Natural Heroes in 2004.

The series has not only provided a national platform for the message that one person really can make a difference, but it has given exposure to films that audiences would not otherwise have the opportunity to see — and brought attention to issues that may have been ignored in the past.

The first two seasons of Natural Heroes aired on public television stations all across the United States, Puerto Rico, and Canada, reaching an estimated 90 million viewers.

The series has been honored with Emmy®, Telly, and Insight awards. Season Three episodes span the globe and take on a fascinating variety of topics with fresh, creative approaches. Subjects range from renewable energy to conservation of marine species, from the meaning of wilderness to the community created by an urban garden.

In an effort to encourage carriage of the series, all episodes of Natural Heroes are made available to PBS affiliate stations free of charge via satellite uplink. All PBS affiliates have the option of showing the programs in real time at the time of uplink, and/or recording episodes for airing at a future date. Season Three uplinks begin in September 2007.
