Ideas for an attention grabber? about saving marine life dolphins turtles etc...?

I have to do a powerpoint on saving the marine life in the ocean. I went to an aquarium/rehabilitation center to take pictures of the animals. My opening line has to be an attention grabber. The teacher said we could use a quote, rhetorical question, description, anecdote, statistic etc. I just need help thinking of one. Does anyone have some good ideas? Thanks!
