Sir David Attenborough’s anguish

Sir David Attenborough has spoken of the “tragic, desperate mess” human beings have made of the planet as he prepares to air his new natural history series.

Seven Worlds, One Planet, which has been four years in the making, features wildlife firsts and has already been snapped up around the globe.

It breaks with the tradition of previous BBC Studios’ Natural History Unit programmes – putting a conservation message “at the heart” of each episode, instead of being tagged on at the end.

Sir David, who presents the programme, said: “We are now universal. Our influence is everywhere.

“We have it in our hands, and we made a tragic, desperate mess of it so far.

“But, at last, nations are coming together and recognising that we all live on the same planet, and we are dependent on it for every mouthful of food we eat and every breath of air we take.”

He also praised teenage environmental activist Greta Thunberg for her high-profile campaigning.

“Greta Thunberg is there because of her passion, her insight and her concern about the future.”
