Fridays for Future protests for climate action were initiated in August 2018 by then 15 years old Greta Thunberg who proposed school strikes to stop global warming and climate change. This turned into a global movement with the week of March 15th 2019 having been promoted for global climate strike action.
The campaign states that “During the week of March 15, there were at least 1.6 million strikers on all 7 continents, in more than 125 countries and in well over 2000 places. The 1.6 million strikers is data gathered by FFF for 40% of countries.
Over 1 million has been confirmed by the 30% of cities, which have reported.”
