What would be an interesting persuasive topic to deliver a speech about?
Why people should get more involved with politics, governmental issues, etc. so they can participate in the present and future of the country and that even one person can make a difference, etc. Or you could talk about the environment and what people can do to make the world a better place and that they can make a difference, etc. Anything as long as you get them involved, has to be something interesting, real, informative, etc. Good luck.
