Use Relevant Images to Support the Idea
PowerPoint is a visual aid and should be used to support or reinforce your point. The retention rate of whatever message communicated visually is much greater compared to the one communicated orally. Hence use more (relevant) images to communicate your idea.

All people love stories and if your content could be presented that way, it will create a great impact on the audience. Most of the subjects affecting our daily life could be presented using a story based approach.
De-Clutter : Avoid All Distractions
Avoid all unnecessary decorations and let the audience see only the core information which you want to pass on.
