The Courtauld Gallery in London had two activists glue themselves to the frame of a Van Gogh painting.
In 1889, just weeks after he slashed his own ear, Van Gogh completed a painting of the French countryside.
The stunt may have hurt the painting.
The two are members of Just Stop Oil, a group that wants the U.K. government to stop fossil fuel licensing.
It's immoral for art institutions to stand by while the government allows for more fossil fuel production, says McKechnie, who claims to be a fan of the movie.
The Courtauld Gallery did not respond to a request for comment on the footage that was posted online.
Provence, the region of France depicted by Van Gogh in "Peach Trees in Blossom'', is in danger of experiencing a severe drought this summer after low rainfall this year, according to Just Stop Oil.
Five members of the group Just Stop Oil were arrested in Glasgow, Scotland, on Wednesday for spray painting the walls and floors of the gallery and gluing themselves to a painting. A man who threw cake on Leonardo Da Vinci's "Mona Lisa" at the Louvre Museum in Paris said he did it to raise awareness about climate change. Don't forget to think of the planet! Think about the people who are ruining the planet. In French, he said that was the reason he did it. Climate change protesters attached themselves to trains, bridges and a fence outside the home of the Labour Party's leader in the year 2019.
