Veteran presenter Sir David Attenborough has urged the public to ditch meat and work towards a plant-based diet in his new documentary A Life On Our Planet.
The film, which premieres in U.K cinemas for one night only on September 28, looks at the environmental changes that have happened on Earth over Sir David's lifetime and offers some solutions to the climate crisis.
'We must change our diet'
According to the Mirror, the historian said: "We must change our diet. The planet can't support billions of meat-eaters.
"If we had a mostly plant-based diet we could increase the yield of the land. We have an urgent need for free land... Nature is our biggest ally."
Sir David also warned that the 'natural world is fading' and predicts the loss of biodiversity, which he describes as the true tragedy of our times - is 'still unfolding'.
'A Life On Our Planet'
"I am David Attenborough, and I am 93. I've had the most extraordinary life. It is only now that I appreciate how extraordinary," Sir David says in the film's trailer.
"The living world is a unique and spectacular marvel, yet the way we humans live on earth is sending it into a decline. Human beings have overrun the world. We're replacing the wild with the tame. This film is my witness statement and my vision of the future.
"Our planet is headed for disaster. We need to learn how to work with nature rather than against it and I'm going to tell you how."
