David Attenborough sent an important warning to humanity and said we are 'close to point of no return'

David Attenborough is never one to shy away from the truth, and that's the case whether he's talking about an animal about to become prey or the state of life as we know it.

The broadcaster is set to share some more truths about our planet when he returns for the third series of Planet Earth III later this year, but he's already made clear that there's no time to waste when it comes to protecting Earth.

Speaking on his 2020 documentary David Attenborough: A Life On Our Planet, Attenborough explained that Earth is getting close to the point of no return due to the impact of humans.

The now-97-year-old broadcaster said: "I've had the most extraordinary life. Human beings have overrun the world. We're replacing the wild with the tame."

“The living world is a unique and spectacular marvel. Yet, the way we humans live on earth is sending it into a decline,” Attenborough continued.

“This film is my witness statement and my vision for the future," he said. "The story of how we came to make this our greatest mistake. And how, if we act now we can yet put it right. Our planet is heading for disaster."

Attenborough warned that if we don't act, we can expect some serious consequences.

"We need to learn how to work with nature rather than against it, and I'm going to tell you how," Attenborough went on, referring to the documentary.

Produced by award-winning wildlife film-makers Silverback Films and global environmental organisation WWF, A Life On Our Planet chronicled Attenborough's extraordinary life, focusing on 'the man who has seen more of the natural world than any other'.

The documentary was one of Attenborough's more recent projects regarding Earth, but he's set to offer more insights to life on our planet in Planet Earth III, which is set to air on the BBC in Autumn.

The series will be made up of eight episodes, and is set to showcase the behaviour of animals from across the globe including African Jacana birds, tropical Mobula rays, the spirit bear of Canada, and demonstrate how animals have adapted to cope with some of the challenges they face in the modern world.

The final episode will focus on humans, and the work that goes into protecting animals.

Attenborough has already started filming his introductory scenes and recording the narration for the new BBC series, which comes just three years before the iconic broadcaster is set to celebrate his 100th birthday.
