Speech!!!

My speech is what would happen if earth lost oxygen for 5 seconds most people just think that we just wouldn't be able to breathe for 5 seconds but their is much more to it than that. I am away in week 6 so i might not be able to present my speech but i will do it anyway just in case. I am sort of nervous for my speech but not that much as i am only presenting it to my class if i was doing in front of the school i would be way more nervous i am using cue cards because i forget things a lot so just o be on the safe side. I really hope i get to present my speech as i have worked hard writing, editing and learning it but at the same time i am sort of nervous i hope my speech turns out how i hoped it would.
