What should i add for an english persuasive speech or what could i add as a fake qualification like about myself or how i’ve been affected

So since this is persuasive and you want to persuade your audience you want to use a CREDIBLE source about your topic (choose a recently dated source ending with a trustable url like .edu), you should include that at least once and be sure to list your source at the end even though you don't have to say it out loud when giving the speech. Pick a source;listing a statistic like the rise of littering and its affects on the environment. When you have evidence youll be more credible and believable.

 I suggest:
 
-Replacing some of your words with more advanced vocabulary but make sure they have the same meaning/definition.

-"So please pick it up" does not sound very appropriate for a persuasive speech so I would say word this differently and also include some more proper vocabulary. 

-It is good to add some sort of experience of your own and why littering is bad on yourself and any emotional impacting story from littering.

I’m just thinking something from the top of my head so it may not be much so if weathering didn’t exist, there wouldn’t be anything to break up earth’s crust naturally. so by assumptions, the rocks on earth would be larger than they actually are since there’s nothing to break them up into smaller parts.overall, i’m not really sure, but all i know is that it’ll mess up the rock cycle that we have now.hoped this .
