Inasmuch as coral reefs represent a complex community of organisms and their environment functioning as an ecological unit in nature, it is not surprising to find that the numerous life systems that coral reefs support include a variety of plants and animals, in that the reef protectively harbors them as a means by which to thwart predators, as well as to provide for the reef itself.

Not only are they poached and slaughtered indiscriminately for sheer entertainment, but they have also been killed in tuna nets and by military underwater detonation. With all the scientific evidence in relation to the dolphin's inherent sense of understanding and its ability to assist people in various endeavors, considerable legal effort has been made to protect this gentle creature from unnecessary death. However, the fishing industry -- where an inordinate number of dolphins are killed -- does not purposely try to catch the mammals; rather, the fact that dolphins swim with the tuna that are caught in the nets is what ultimately seals their fate. The writer discusses various reasons why dolphins are killed. Bibliography lists 5 sources.
