A blueprint for a more balanced, sustainable world by King Charles III.

For more than 30 years His Royal Highness Prince Charles The Prince of Wales has been at the forefront of a growing ecological movement. Originally treated with scepticism, many of his ideas are now widely accepted and gaining increasing impact and influence. His work has sought to meet a huge range of modern challenges, from urbanisation to deforestation. In every case, however, the philosophy that is the foundation of his work has always been the same, but has always been unspoken, until now.

For the first time, Prince Charles, with the help of his two leading advisors, has brought together his vast knowledge and experience to set out this philosophy – a philosophy that is as robust as it is practical.

In Harmony, Prince Charles looks at different aspects of our modern world to demonstrate how many of the challenges seen in areas as diverse as architecture, farming and medicine can be traced to how we have abandoned a classical sense of balance and proportion. From the rice farms of India to America's corn belt, Harmony spans the globe, dissecting the specific practices of modern life that have put us at odds with the world and showing how this imbalance manifests itself throughout our lives.

Harmony shows how the imbalance that has emerged is at heart of a crisis which now threatens our very civilisation. It tells the story of how our disconnection from Nature has contributed to the greatest crisis in the history of mankind and how seeking balance in our actions will return us to a more considered, secure, comfortable and cleaner world.

Drawing on his own practical experience, Prince Charles charts how changes to how we look at the world could lead us toward a better future. He describes how knowledge and perspectives now largely lost could help us meet very modern challenges, including in the built environment, engineering, medicine and farming.
