Captivated by the mating habits of jellyfish, elephants mourning their ancestors, and proud lionesses cuddling their cubs, audiences love to peer into the private lives of creatures great and small—particularly in spectacular settings around the world.
A study by the BBC and the University of California Berkeley revealed why viewers choose to kick back and tune into programs like "Honey Badgers: Masters of Mayhem" and "The Tigers of Scotland"—nature documentaries trigger the neurochemicals of happiness, reducing stress and anxiety.
Some of the best proponents of the genre come from the BBC Natural History Unit, which has been cranking out award-winning nature documentaries since 1957, often in conjunction with natural historian and television producer Sir David Attenborough. Now in his 90s, Attenborough has worked with the BBC for over 60 years. He is the genius behind several acclaimed series, including "Life" and "Blue Planet," which millions worldwide continue to watch.
In recent years, a growing number of filmmakers have used their platforms to raise public consciousness about the many threats posed by global warming.
Coral bleaching, rising sea levels, farm animal cruelty, and melting polar ice caps have all been the subject of documentaries, as well as the significant role played by human beings concerning climate change and environmental degradation.
Celebrity activists like Leonardo DiCaprio and Oprah Winfrey have also lent their status to the movement, behind the camera and in front of it.
