Film length: 8:35

Over 600,000 people marched worldwide on the eve of the COP21 climate talks in Paris, with over 50,000 marching in London. In Paris, where demonstrations have been banned, 5,000 still successfully marched despite police violence, and 10,000 joined a human chain. Now the ban has been successfully broken, huge numbers are expected on the streets in Paris on December 12 for the day of mass civil disobedience as the talks finish.
