Horse speech topic ideas?

I am doing a speech for 4H I'm a junior so I only have 5 minutes to talk. I have a few speech topics in mind and I want your opinions. The topics I like are micro chipping horses, horses impact on the economy, and how young is to young for a horses to be competing. Or if you have any ideas of different topics. It MUST be about the something pertaining to the horse industry. and I can't have visual aids not poster boards or pamphlets or anything. Thanks!!
