Sarah Ferguson takes a break from plugging her romance novel to issue plea about climate change

Sarah Ferguson has revealed her crusade to combat climate change as she reveals becoming a grandmother has made her ‘terrified’ about the state of the planet.

The Duchess of York, 63, who was raised on a farm and was surrounded by nature throughout her childhood, has revealed her grandchildren August, Sienna and Wolfie have given her a sense of ‘urgency’ about doing all we can to reduce the effects of climate change.

Writing in The Telegraph on Earth Day, Fergie spoke of her dedication to preserving the planet for the sake of younger generations.

Her article comes as her daughter Princess Eugenie, 33, shared a photo of two of Fergie’s grandchildren, August Brooksbank, two, and Sienna Mapelli Mozzi, one, enjoying the penguin enclosure at London Zoo.

Eugenie wrote that Beatrice’s daughter Sienna, who was pictured publicly for the first time, ‘loved’ going to London Zoo in Regent’s Park with her older cousin August, in a series of photos that commemorated Earth Day.

Writing about her commitment to preserving the environment for future generations, the Duchess of York said: ‘Now, as I embark on a new phase of life as a grandmother to August, Sienna and Wolfie, my love for nature is translating into a sense of urgency about climate change and the environment. 

‘I feel strongly that my generation has a responsibility to hand a sustainable planet on to our grandchildren.’

Christopher ‘Wolfie’ Woolf is Edoardo Mapelli Mozzi’s six-year-old son from a previous relationship.

The Duchess added that her love of nature extends to animals as she revealed she’s at her happiest when horse riding or taking care of the late Queen’s corgis, Muick and Sandy.

As she noted more extreme temperatures around the world as Britain experiences the hottest summers on record, Fergie argued the issue of climate change was no longer up for debate.

Another thing she said could not be ignored was that humans have been the cause of much of the damage to the planet over the last century.

As she made the case for action against climate change, Fergie praised Princess Eugenie’s work with Project 0, for which she is an ambassador, in trying to protect the ocean from plastic pollution.

The Duchess revealed she does her bit too, as a keen recycler who uses ‘environmentally friendly products’ wherever possible.  

Princess Eugenie also marked Earth Day with an Instagram post containing photos of her son, August, and her niece Sienna.

Posting a snap of the cousins at London Zoo, she said: ‘August and his cousin Sienna love going to the London Zoo. It’s part of the Zoological Society of London, a global wildlife conservation charity that helps to restore habitats and protect wildlife. Every time you visit you are supporting their work.’ 

In the other photos, Princess Eugenie shows little August enjoying a BBC Earth experience, an immersive screening from the BBC’s Natural History Unit. 

The final photo in the series is a snap of little August walking with his father, Jack Brooksbank and the family Labrador through a picturesque woodland filled with blossoms.

She wrote of the last photo: ‘Because I love them and they love nature.’

Elsewhere Eugenie posted a photo of herself examining oysters as part of her work into coastal conservation.

She wrote: ‘Who knew oysters were so cool… one oyster can clean up to 200L of water a day.
