The Duke and Duchess of Sussex also took to Instagram to show their support.
In an Instagram post, Harry & Meghan write: 'From areas we are personally connected to such as the communities and people we visited in New South Wales in 2018, to the fires in California and parts of Africa, we are struck by the increasingly overlapping presence of these environmental disasters, including of course the destruction of the Amazon which continues.
'This global environmental crisis has now been described as Ecocide. It’s easy to feel helpless, but there’s always a way to help.'
The royals then went to add links to fundraising efforts to help victims and firefighters.
