Laura Whitmore, Victoria Beckham, Eva Longoria and Paul McCartney are among the celebrities praising the "incredible" planet on Earth Day.
A number of well-known faces have shared messages about sustainability and environmental conservation on Earth Day, which was created to prompt action on the environment and climate change globally.
Irish broadcaster Laura Whitmore posted a photo of herself stretching beside a pool alongside a poem.
She wrote: "Dear Earth, I am so grateful for you, Your consistent giving although we don't always give back.
"Enabling us to survive with your resources, even though things have begun to crack.
"But now it’s our turn to be kind to you, Not just take and enjoy the view, So I pledge to do better and help you thrive, And keep you turning so you can keep all creatures great and small alive."
Former Beatle Paul McCartney, a long-standing vegetarian, shared an image of himself performing against the backdrop of the Earth.
He wrote to his 3.5 million Instagram followers: "Celebrating #EarthDay. It’s the only one we’ve got!"
Popstar turned fashion designer Victoria Beckham shared a black and white photo taken by her eldest son Brooklyn of a lion pouncing, describing it as "one of my favourites".
She wrote on Instagram: "Happy #EarthDay our planet is so incredible! We can all, and must, do better to take care of it."
Film and TV star Eva Longoria also posted a lengthy message to her Instagram followers.
"Let’s do better to live more sustainably and protect our earth every single day," she wrote.
"Any change – big or small – is a step in the right direction. Get outside and join a global cleanup, advocate for action on climate change, fight food waste, buy local, educate your peers, reuse and recycle…the options are endless. We have one home, let’s take care of it!"
Game Of Thrones star Maisie Williams promoted her partnership with the charity Choose Love by posing wearing a branded t-shirt.
She wrote: "It’s Earth Day and I ask you to CHOOSE EARTH!
"My friends over at @chooselove have launched a campaign raising desperately-needed funds for the incredible Brazilian indigenous leaders dedicating their lives to protecting the rainforest from destruction. This work is a vital part of the battle against climate change and is essential for the future of our planet."
