Persuasive Essay Help?

I'm an 8th grader who needs to write a short persuasive essay, but I'm having trouble thinking of a topic. I prefer to write about animals and/or the environment. :P Please don't suggest: White Tiger Inbreeding, Deforestation, Recycling, Polar Bears & Global Warming - etc, since i've done a report on all of those this year, nor that overused topic of using animals for research. And also...please don't bother telling me to come up with something myself. ;D Please and thankyou.
