A speaker is giving a speech on pollution in the ocean.What would be the best format for the speaker to add to the speech to have a greater influence on the audience?

A video showing a beach full of litter gives the audience a vivid, direct example of ocean pollution. Seeing the pollution can make the problem feel more real and strengthen the speech’s impact. A book, editorial, or map may provide information, but they are less immediate and persuasive for this purpose.
