Chinese performance artist Liu Bolin's latest artwork has him camouflaged against a backdrop of rubbish picked up by children from beaches.

The installation, set up at non-profit organisation Surfrider Foundation Europe's headquarters in Biarritz in south-western France, aims to highlight the pollution of the world's oceans.

Liu, 44, who is from Shandong province, is known as "the invisible man" for using painted-on camouflage to blend himself and his subjects into the backdrops of his photographs and artwork to raise awareness about political and societal issues.

He once told CNN: "Disappearing is not the main point of my work. It's just the method I use to pass on a message. To tell people, if we don't stop the way we live, or pay attention, we will all face our own disasters. It's my way to convey all the anxiety I feel for human beings."

His most popular works are from his Hiding In The City series, where he camouflages himself into various settings in Beijing.

The series was meant as a silent protest, calling attention to the Chinese government's lack of protection for artists.
