Prince William has said fatherhood helped spur him on in his wildlife conservation work, as he wants to protect nature for future generations.
William, 38, was joined by a film crew two years ago for a documentary called Prince William: A Planet For Us All, which will be aired on ITV next month.
The father-of-three said he had “always loved nature” but that having children had given a “new sense of purpose” to his conservation work.
He said: “Now I have got George, Charlotte and now Louis in my life – your outlook does change. You want to hand over to the next generation, the wildlife in a much better condition.”

He added: “I always believe it is possible to give young people hope and belief that things can get fixed.
“I have the belief that if we all work together, we can make a difference.”
The documentary will follow William as he meets people in the UK and abroad who are helping to protect and restore the environment.
Kensington Palace said the film will show how William moved from being passionate about conservation to wanting to play a greater leadership role on the environment.

In a clip from the documentary that has been shared online, the Duke and Duchess of Cambridge meet Sir David Attenborough, and Kate reveals: “The children were very upset that we were coming to see you and they weren’t coming.
“They’re massive fans of yours.”
William appears to be following in his father’s footsteps in his passion for the environment.
Prince Charles, 71, has been a long-time campaigner on similar issues, and this week called for global commitments to tackling carbon emissions to be brought forward by two decades.

In a keynote speech delivered to launch Climate Week, the heir to the throne called for a “war-like footing” to “combat this most grave and urgent challenge”.
He also said: “Without swift and immediate action, at an unprecedented pace and scale, we will miss the window of opportunity to ‘reset’ for… a more sustainable and inclusive future.
“In other words, the global pandemic is a wake-up call we cannot ignore…
“…[the environmental] crisis has been with us for far too many years – decried, denigrated and denied.
“It is now rapidly becoming a comprehensive catastrophe that will dwarf the impact of the coronavirus pandemic.”
Prince William: A Planet For Us All will air in October.
