In October 2019, and for a period of two weeks, climate activists from Extinction Rebellion, Animal Rebellion, and beyond took to the streets to demand that the UK Government declare a climate emergency and commit to making radical changes to prevent further global warming and mass biodiversity loss. The October Rebellion took place internationally but for the UK, activies were centered in London. Activities included: (a) blocking streets and stopping traffic in London’s financial hub and adminstrative core to highlight the impact of the transport sector and financial and government institutions on the climate and ecological emergency, (b) grounding buses to a standstill as protesters glued themselves to the roads and protested outside the office of fund manager BlackRock to demand it stop investing in fossil fuels, (c) staging ‘Justice: An Inconvenient Trial‘, a street play about the trial of the financial sector, and (d) the symbolic occupation of Smithfield Meat Market and the disruption of Billingsgate Fish Market, to highlight the need for a transition to low-carbon, non-exploitative diets. Hundrets of activists were arrested for the disruption caused. However, the statement that the status quo cannot continue was clearly heard and, as a direct result of these activist actions, a climate emergency was declared by the UK Government.
