“This is not a game” says co-founder of Extinction Rebellion, Roger Hallam. This interview was filmed just before the start of huge political mobilisations in London and across the world.

Roger talks about how the rebellion began, the theories based on successful civil rights victories of the 20th century, and the reaction of elites to the challenge in practice.

For more in-depth explanation of the theories which have powered the mass mobilisation of this movement, see our films of Roger Hallam’s lectures.
