You'll have to think that one up on your own. What have you learned from your research on Hollywood? Why do YOU think it has a negative impact? When you're writing a speech, you can't just copy down any old sentence and plot it down into your speech and hope it fits. You have to write one based on what the rest of the speech says and on what you personally know.
Your opening sentence is going to depend entirely upon what your writing is about! You'll have to finish the whole thing first and then pick out which sentence or idea is best to lead off with.
I would like to avoid a hard sell opening in persuasive message to make the persuasive message more credible.
about television because daily students watch television so...
"In a world teetering on the brink of environmental crisis, the urgency of conservation has never been more paramount."
"Imagine a workplace where leaders prioritize building strong relationships as the foundation for success."
