For the purposes of the debate, 'radical environmentalism' refers to the use of aggression or disruption (e.g. vandalism, sabotage, civil disobedience) in the name of environmentalist campaigns. An example of 'radical environmentalism' was when members of the Just Stop Oil campaign vandalized Vincent van Gogh's "Sunflowers" in the National Gallery and subsequently glued their hands to the wall in 2022.
