The video shows a man standing on a stage in front of a large audience. He is wearing a black t-shirt with the text \"BY 2050 MORE PLASTIC IN OUR OCEANS THAN FISH\" printed on it. The man is holding a spool of orange filament in his right hand and a 3D printer in his left hand. He is speaking into a microphone and appears to be giving a presentation or speech. The stage has a large sign with the letters \"TEDx\" on it, indicating that this is a TEDx event. The audience is not visible in the video, but the setting suggests that it is a large venue with seating for many people. The man's expression is serious, and he seems to be engaging with the audience as he speaks.
