Around 50 pupils and teachers from Phorms Gymnasium took part in the nationwide day of protest against climate change. As part of an inter-grade field trip, they took part in the demonstration and rally organized by the Fridays for Future movement in Frankfurt.

"Our planet is our only home. Where are we supposed to go if we destroy it?" The Dalai Lama's sentence is written in large letters on the poster that Sina and Olivia are holding up to the sun against the backdrop of the Alte Oper opera house in Frankfurt. The two ninth-graders designed it themselves in class and most of the other Phorms students are also represented with slogans and pictures on cardboard, from "Save the whales - it's not their fault!" to a globe that runs like sand through an egg timer: "Time's up!"

In light of the United Nations General Assembly in New York, the "Fridays for Future" movement called for action against climate change worldwide on this day. According to the organizers, around 1.4 million people took to the streets in Germany alone. Phorms-Gymnasium gave students in years seven to twelve the opportunity to take part in the voluntary field trip.

It was important to the school management and teachers that participation in the demonstration was closely linked to lessons. Not only were the posters designed together, but the topic of climate protection was also dealt with intensively in a number of classes: "For example, we calculated the climate footprint that each of us left behind during the summer vacations," says geography teacher Heike Dittrich, for example, who accompanied the pupils to Frankfurt.

In the end, the Phorms delegation is particularly impressed by the sheer mass of the tens of thousands of demonstrators on the square and later in the high-rise canyons of Frankfurt's city center. Tens of thousands who, like Sina, Olivia and the other Phorms students, wanted to show that this planet is their only home.
