From September 20 to 27, thousands of people of all ages are coming together in 150 countries to demand action from their governments on climate change, as part of a planet-wide series of actions inspired by climate activist Greta Thunberg’s weekly Fridays for Future protests in Sweden. For months, young people around the world have been participating in Greta’s weekly strikes to demand action from politicians. Their message is simple: the consequences of climate change are far worse than anything we can imagine and must be addressed as such. No one is impervious to climate change’s myriad and far-reaching effects. Thus, we all must mobilize to make history and enact change.
