The five-part series will explore the perfect conditions that planet Earth provides for life to flourish.

A Perfect Planet will explore how the forces of nature, such as weather, ocean currents, solar energy and volcanoes, drive and support the diverse range of life on every corner of the Earth.

David Attenborough said: "Oceans, sunlight, weather and volcanoes - together these powerful yet fragile forces allow life to flourish in astonishing diversity. They make Earth truly unique - a perfect planet.

The five-part series from BBC Studios Natural History Unit has been described by executive producer Mike Gunton as “Planet Earth for plants!”

The Green Planet will offer an unseen look into the inter-connected and surprising behaviour of the plant world, where unlikely heroes and emotional stories emerge.

Attenborough will discover plants that can outlive civilisations, and others that could cover the Earth in a matter of months with their ferocious breeding patterns.

Shocking scenes of walruses jammed together “out of desperation” on an ice-depleted beach, a consequence of climate change, have emerged as the defining image of Netflix’s high-­profile natural history documentary, Our Planet.

Secrets of the Royal Babies: Meghan and Harry

Monday: ITV, 9.00pm

ITV's one-off documentary explores what it’s like to experience motherhood as a royal.

Secrets of the Royal Babies follows the Duke and Duchess of Sussex as they prepare to welcome their first child, and look at how royal mothers have balanced their public duties with motherhood.

Blue Planet II reached over 37m people in the UK alone. Following the final episode, over 60% of people surveyed commented that they wanted to make changes to their life to reduce the impact on the ocean.

The response, said Attenborough, has left him “absolutely astonished.”

“We hoped that Blue Planet II would open people’s eyes to the damage that we are doing to our oceans and the creatures that live in them.  I never imagined that there would be so many of you who would be inspired to want change.”

Each episode will follow an individual animal – lions, hunting dogs, chimpanzees, tigers and emperor penguins – at the most critical period in their lives as they navigate the world’s rapidly changing habitats.

This series will show for the first time what an animal must do to create and maintain a dynasty, and leave a legacy in nature.

Made by the team behind Blue Planet II, the most watched programme of 2017, the BBC aims to recapture its success with new ‘intimate animal dramas’.

As BBC Studios’ Natural History Unit turned 60 this autumn, 2017 was a particularly exciting and busy year. But I was nervous about whether Blue Planet II would equal the impact of Planet Earth II almost a year previously.

In November 2016, Planet Earth II attracted record TV audiences in the UK; the series went on to win RTS, Bafta and Emmy awards. That sequence of racer snakes hurling themselves at hatchling marine iguanas won a Bafta for TV’s most memorable moment.
