Extinction Rebellion is an worldwide protest group that uses non-violent civil disobedience to campaign on environmental issues. "That is why we need the creation of a national Citizens' Assembly on climate and ecological justice".

"We should show that we're making a difference rather than simply telling everyone how important it is to change".
