Banksy confirms new graffiti in London: Green tree on Hornsey Road. At first there was only speculation that the street art star could be behind the mural.

The artist has now confirmed via Instagram: The tree, refined with leaves, comes from him. The message of the work is clear, said James Peak, who made a documentary series about Banksy for the British broadcaster BBC. "Nature is fighting, and it's up to us to help it grow back," he said.
