write a persuasive speech where you will try to change the world

Hello everybody my name is Sovanny Dekeister i’m going to talk about how i am going to change the world.
To start with we should preserve our world by limiting our amount of wast(composting for example). For furthermore i think we should help each other out by communicating to each other and to finish with don’t change who you are to please someone else. That is all i have to say sorry its kind of short but i don’t have the time.
