M: Fellow scientists, I finally have some good news to report. As you know, I have been studying sea life for three months in New York Harbor. Today, I can finally present some hard evidence that sharks have returned to these waters. For the past two weeks, I’ve been helping to film the Shark Week program for the Discovery Channel on TV. My job was to sit in a boat near a dead whale and check it for shark bites. It’s been a very hot July, so this wasn’t the easiest task. After five days, I noticed there were several large shark bites along the stomach of the whale. I was thrilled, because this means our conservation efforts are starting to pay off. Sharks’ returning to a former hunting ground indicates that the waters are cleaner and healthier. We have been trying to clean up this area and the rivers that poured into the harbor for many years. I want to take this opportunity to thank the Environment Friends Society. You have all made your best effort so that future generations can live in a clean world.
