The tone of this article is highly critical towards those who complain about the challenges and adversities that life brings upon them, or that they bring upon themselves, and, instead of seeing them as opportunities to surpass themselves and even excel, they focus on feeling sorry for themselves, and expect others to feel the same way about them. They adopt a conformist attitude that might be reflecting a lack of confidence or a limited capability. Furthermore, the tone of the article is outspoken yet encouraging. Life may not be fair, and it is certainly not easy, particularly for some people, but a positive attitude and personal drive can go a long way to make the most out of it.
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]
