One of Britain's best-known masterpieces became the backdrop for a demonstration at London's National Gallery on Monday, one in a series of protests at cultural sites by British environmentalist group Just Stop Oil.

"The reimagined version carries a nightmare scene that demonstrates how oil will destroy our countryside," the Just Stop Oil group said in a statement. "The river has gone, to be replaced by a road, airplanes fill the sky, pollution belches from cities on the horizon, trees are scorched by wildfires, an old car is dumped in front of the Mill and the famous Hay Wain cart carries an old washing machine."

Notably, the National Gallery writes about "The Hay Wain" original that the artist's idyllic rural landscape captured "a sense that this way of life was changing due to rapid industrialization – the factories, steam power and locomotives that appear in works by his contemporaries, such as Turner, are absent from Constable’s paintings."

Just Stop Oil members have recently adhered themselves to the frames of paintings across the U.K., including Vincent van Gogh's "Peach Trees in Blossom" at the Courtauld Institute in London, and other artworks in Manchester and Glasgow.

On Tuesday, a 15th-century copy of da Vinci's "The Last Supper" at the Royal Academy in London was inscribed with "No New Oil" in spray paint underneath the canvas with five protestors glued to its frame.

The group is calling for the UK government to block licenses for future oil and gas extraction to mitigate climate change impacts. Just Stop Oil called for art institutions "to join them in civil resistance," according to a statement.

The pair of protestors at the National Gallery were arrested and then released, according to the BBC.

"I want to work in the arts, not disrupt them, but the situation we’re in means we must do everything as non-violently as possible to prevent the total collapse of our ordered society," said Eben Lazarus, a 22-year-old music student, in a Just Stop Oil statement.
