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]
Yes, they are. The protection of the human rights abuses is protected under the human rights law. The law puts positive obligations towards the victims. It was stated in the Articles 2,3, and 4 in the Human Rights Law that "<span>Everyone’s right to life shall be protected by law. No one shall be subjected to torture or to inhuman or degrading treatment or punishment. No one shall be held in slavery or servitude. No one shall be required to perform forced or compulsory labour."</span>
