Slow Up did not come out of nowhere. It grew from an earlier moment of collective courage. On 20 September 2025, Worried Citizens brought more than 11,000 people together in front of the Atomium in Brussels to Show Up for Humanity. Over 700,000 people followed along via livestream and show up had more than 16 million impressions in press. Together, they showed something powerful: we have not given up on each other, nor on our planet.

On one stage, 60 artists and speakers from different backgrounds came together, including Zwangere Guy, Selah Sue, Sylvie Kreusch, Zap Mama, Blackwave, Balthazar, Francesco Schuster, Nienke’s Gravemade, Elisabeth Lucie Baeten, Simon Gronowski,  David Van Reybrouck, Max & Venetia Lamanna, Axelle Red, Colt, Adelaide Charlier, Tine Embrechts, Nora Gharib, Omdat Het Kan and Average Rob… By sharing the stage, they sent a clear signal: despite our differences, most people want the same thing — a fairer, more sustainable and more solidary world.

Show Up for Humanity was not just a protest, but a collective affirmation. A reminder that hope is not naive, that solidarity still exists, and that when people show up together, a different future becomes visible.
