For more than four decades, His Royal Highness The Prince of Wales has been at the forefront of the growing ecological movement.
In 2010, "Harmony: A New Way of Looking at our World" written by The Prince, with Tony Juniper and Ian Skelly was published by Harper Collins and in 2012 the film was screened at the Sundance Festival in London.
Harmony outlines the principles of reconnecting Man and Nature. Drawing on his own practical experience, The Prince charts how changes to the way we look at the world could lead us toward a better, sustainable future.
The series of audio extracts below, narrated by The Prince of Wales, are from various chapters of Harmony.
There will be more extracts to follow each week.
