Richard Turere TED talk
The main message was that no animal deserves to die. That means that there is no point to killing animals when you can just make something and save time and animals.
Richard got his message across very well. He weaved his message into a story. This is effective because it makes the audience feel emotion. Also he used lots of pictures to entertain and to help explain his story.
Richard used a bit of technical support like the usual head set to project his voice to the audience. He also used a clicker to change the pictures behind him these helped because they backed up what he was saying.
Richard used a couple of presentation techniques, like putting humour into the suitable bits but he did not put to much in because it was a serious topic. He also put a timeline in so he sort of took the audience on a journey and made them feel emotion.
