Speech Ideas.

I have to write a speech. In the beginning I had no inspiration for my speech. Because they weren't decisions or thoughts I thought about strongly. I was going to do something about plastic surgery. I don't know how it came into my mind but I thought of the speech idea: Barbie=Good example?. I felt very strongly about this topic as you might feel strongly about religion. Because I didn't think Barbie's examples for girls are were good enough. What do you feel strongly about? Make-up testing on animals? Circuses? Zoos? Beauty Pagents? Should films'/Gaming be rated only as a suggestion? Should smoking be illegel? Should plastic surgery only be done on people who need it? Are you for or against?
