Answer:
The mechanisms used to produce sound vary from one family of cetaceans to another. Marine mammals, such as whales, dolphins, and porpoises, are much more dependent on sound for communication and sensation than are land mammals, because other senses are of limited effectiveness in water. Sight is less effective for marine mammals because of the particulate way in which the ocean scatters light. Smell is also limited, as molecules diffuse more slowly in water than in air, which makes smelling less effective. However, the speed of sound is roughly four times greater in water than in the atmosphere at sea level. As sea mammals are so dependent on hearing to communicate and feed, environmentalists and cetologists are concerned that they are being harmed by the increased ambient noise in the world's oceans caused by ships, sonar and marine seismic surveys.[2]

Explanation:
Dear Tiffany,
It has come to my attention that there is a ton of litter in the neighborhood park! It makes me sad to see no children playing there because of the mess. If we could clean up the area, it would make our neighborhood look much nicer than before. My idea is that we should host a clean-up day. We can make posters called, “Spring Day Cleanup!” and put them around the neighborhood. I can also get my mom to mention it at the next Neighborhood Board Meeting.
There is also this charity that helps children afford books. It’s called “Reading for Everyone”. They give out text books, book bags, school supplies and more. They’re known worldwide for all that they have done! I’ve recently become very intrigued in their work lately, and I was thinking we could help them out. We could sell lemonade, and cookies to the workers after the cleanup. We could also sell trash bags and gloves. With the profit, we can donate it to the charity. It’s like killing two birds with one stone. We help out our neighborhood park and the “Reading for Everyone” charity.
My reason for writing to you is; would you mind helping pass out fliers, and then on the day we have the cleanup, would you help serve lemonade? It would mean a lot to me, and I will also be there to help! Together, we can clean up the park, and make kids happy. Please consider it, and I look forward to your letter back.
Sincerely,
Your name
