Millions of people in cities around the world took to the streets Friday to call for immediate climate action. A large portion of those protesters are teenagers and schoolchildren, inspired in part by the Swedish environmental activist Greta Thunberg, whose group, Fridays for Future, led students to skip school on Fridays to go on strike. Thunberg, who is now 16, has said that more than 4,600 events in nearly 140 countries had been scheduled for this week’s climate strike. The event appears to have grown even more than anticipated, and more than 150 countries have reportedly seen climate events.
Here are some of the best signs from Friday’s march.
Demands for a Future
It’s no surprise that young marchers’ frustration and anger over the complacency of older generations powered much of the movement. On Friday, those young people made it clear they don’t plan to stop fighting for their own say.
Pleas From the Very Young
Some of the most powerful signs on Friday came from the youngest protesters.
Thanks to Greta
Thunberg, the hero of the movement, was invoked often as a rallying cry for action.
No Thanks to Donald
While he wasn’t the only politician targeted by the signs, President Donald Trump was a subject of anger in derision in more than just the U.S. marches.
Marching in Costume
A number of protesters got into character to deliver their message.
Anger Through Comedy
The situation may be serious, but some brought some (righteously angry) humor to the scene.
Telling It Like It Is
The point of the day was to remind lawmakers that climate change calls for urgent action. Children and teenagers delivered with a mix of innocent politeness and gleeful vulgarity, but the point was the same: We’re here because you’re not doing enough.
