Street artist Banksy unveiled a fresh mural in London on St. Patrick's Day, delivering a potent green message.

The enigmatic political activist subtly staked claims on the authorship of the post by sharing before-and-after pictures on his Instagram without any text.

A green figure on a mural on a building wall, against the background of a bare tree stripped of its leaves, which were once lush green, holds a paint sprayer while looking at the lifeless plant.

"I think this is a lovely piece of work; it's interesting, and I think it's appropriate to do this," said Mr. Corbyn, who remains an MP but is no longer Labour leader. "It's our country; it's our environment—it's clearly very clear how our ecosystem is in temporary danger. Islington Council has confirmed to the Islington Tribune that their graffiti removal crew will not be cleaning off the mural, but its future remains uncertain due to the state of the wall.

The BBC added that the tree, between 40 and 50 years old, is decaying and suffering from fungal damage that is causing health problems. A lot of attempts have been made to elongate the life of the tree, but the condition is getting worse.

Banksy, who began as a graffiti artist, is notorious for his 'poison dripping from the tip' asides. His real identity remains a mystery to the public, but his art sells for millions in art auctions. His portfolio is littered with controversial images such as kissing policemen, rioters with smiley faces, and a monkey with a sign reading, 'Laugh now, but one day I'll be in charge'.
