More than 500 images of people were projected onto the facade of France's National Assembly building in a collaborative effort of French artist JR and the American filmmaker Darren Aronofsky. "Standing March" is the representation of humanity to remind leaders the world is watching as said by the artists behind the project.

Time Magazine reports that the massive artwork in France which was showcased during the 2015 United Nations Climate Change Conference (COP21) was a call for climate change solutions. This is intended for the 25,000 world leaders in attendance in Paris to formulate plans that will limit the greenhouse emissions and stop the further increase of global temperature.

The controversial director behind "Requiem for a Dream" and "Black Swan" expects actions from global leaders to combat climate change. "We expect decisions, we expect commitments and we expect time frames", Aronofsky said in a statement on the project's website.

"It's about people, from Tuvalu to New Orleans, whose lives are threatened by climate change. The world depends on a solution."

The said exhibition will travel around Paris for seven days after the display on National Assembly building.

JR has described the artwork as a silent march since marches are forbidden in Paris for security reasons following the attack that left 130 people dead. He added that they are marching with the support of Assemblee Nationale which is said to be the heart of democracy.

"We must think about our future, the future of our environment and this is our answer to those who want to control our present."

Pitchfork also reports that Massive Attack has composed the original score for the said exhibition. Meanwhile, Thom Yorke was also reported to DJ while atop a Greenpeace float during the climate change march in London. It was previously reported that he had signed a petition together with David Bowie and Bjork calling for world leaders to negotiate a deal during the conference.
