Prince Harry has spoken for the first time since Prince Philip's funeral, lending his voice to a charitable campaign video where he paid tribute to his grandfather.
The 36-year-old, who returned to the UK for the first time in more than a year for the Duke of Edinburgh's funeral service on Saturday, is heard narrating an African Parks video, in recognition of Earth Day.
The non-for-profit conservation organisation, of which Harry is president, released its Hope Starts Here video, and Harry is heard talking about the importance of biodiversity in African communities.
Harry released a press statement alongside the video, where he honoured Philip – also a fierce conservationist.
"On this Earth Day, I reflect on generations of conservation champions, including my late grandfather, and feel proud and energised to continue doing my part in this legacy," Harry said.
"As we now begin to move towards an era of global recovery and regeneration, it's critical that we continue to look at the strengthening and protecting of biodiversity, not just as a value we hold — but as a responsibility that is vital to our way of life."
Harry flew back to the US on Tuesday to be with his pregnant wife Meghan, just a day before the Queen's 95th birthday.
He spent nine days in the UK, the first time he'd been back home since his and Meghan's bombshell interview with Oprah Winfrey in March.
It is expected Harry will return to the UK in July to stand by his brother Prince William at the unveiling of Princess Diana statue, on what would have been her 60th birthday.
Africa has always held a close place in Harry's heart; the prince previously referred to it as his "second home".
When Meghan first came into his life in 2016, they spent their third date in Botswana and say this is where they fell in love.
They returned a year later for Meghan's 36th birthday, and later shared a rare photo of their trip which showed them equipping elephants with satellite collars.
Harry also chose a diamond from Botswana as the centrepiece of Meghan's engagement ring, which also features diamonds from Princess Diana's ring.
