With the current epidemic, I decide to do a review on this Ted talk by Bill Gates from 2015. It is a presentation explaining why the world is not ready for the next disease outbreak and the areas should be improved on in the future.

At first Bill used a nuclear survive cell in the back to resonate that it is no longer the problem we are facing now. Then he brought up the Ebola epidemic that happened before and how poorly it was being treated, it showed us how unprepared the people were. Bill then extends the fact that Ebola is not even a huge disease, it does not spread that fast, there are far more dangerous diseases out there. After that he showed us if we do nothing and an epidemic happens, the death count and the economic loss. Near the end, he suggested some solutions on how to prevent an epidemic from happening and how to treat it if it happens.

In his presentation, Bill followed multimedia principle, he uses PowerPoint to help the audience to learn have a better understanding of the messages. During his presenation, his PowerPoint slides are very efficient and effective, there ain’t many text on the slides, they were only used when important data comes up. This shows the use of the modality principle. The use of colour is also very professional and simple, it does not distract the audience from the information that he is trying to show. Bill uses signalling principle in some of his slides to highlight the key information, for example in the slide where he showed the death count of the EBOLA epidemic, he used bond and orange to highlight the number. Overall a great presentation packed with good information and useful knowledge.
