The video depicts a large crowd gathered in a public space. Most of the participants are holding flags and banners that are predominantly green and white, suggesting a demonstration or protest related to environmental issues. Green smoke fills the air, adding to the atmosphere of the event. In the background are modern buildings, indicating an urban setting. The sky is overcast, giving the scene a muted, grey tone. The people are generally dressed in casual clothing appropriate for cooler weather, and some individuals are wearing high-visibility vests. A large green balloon is floating above the crowd.
