During the early 1970’s, a highest level ever in the physical environment, fuelling outrage by the government and activism, led to the passage of several new U.S. laws on environmental protection. Congress adopted the Marine Mammal Protection Act (MMPA) (3) for the year 1972 to address many problems related to marine mammals, the large number of dolphins killed by fishing for the purse seine fishing method the yellowfin tuna in the eastern tropical Pacific (FTE) (4), a 5 to 7 million square miles of ocean area, for example, Southern California on the Chilean coast, west and Hawaii . (5)
The MMPA, a moratorium on the removal (or killing) and the import of marine mammals, including dolphins, with the exception of those who, by the way, during the commercial fishery. (6) Recent changes to MMPA reiterated that the main viewpoints of American origin and intent of Congress that marine mammals have proven themselves to resources of great international importance, aesthetic and economic and recreation, and this is the sense of Congress that they should be protected … “(7)
It was the voice of an entire nation, under pressure to adopt Congress of the MMPA, but it was the actions of a man, in which government attention to the declining populations of dolphins in the ‘TVE industry yellowfin tuna Fang methods. In 1988, Sam LaBudde American marine biologist hired a courageous and dangerous mission: he recruited as a cook on a boat in Panama and the tuna purse seine vessels secretly filmed activities. (8) LaBudde was the first person to successfully collect the slaughter in this film. (9) LaBudde widely published images show the brutal destruction of dolphins then banality in purse seine vessels. (10)
LaBudde images has been the catalyst for a reorientation of the debate on dolphins and FTE purse seine tuna fishing. (11) Initially, it was a purely domestic dispute focuses on the large number of dolphin deaths. After the MMPA and its changes successfully reduced dolphin mortality, the debate’s focus shifted. The issues of recovery of dolphin population, protection of marine biodiversity, international relations, fraud and consumers have largely replaced the dolphin mortality since the central themes of the debate. (12) The debate has also broadened the prospects for a national production of an international audience with a passage from contracts such as the La Jolla Agreement and the Declaration of Panama.
With this reorientation of priorities, a schism has united in advance of the environment. Several environmental groups have provided what they believe, a real balance between the economics of fishing and dolphin mortality. Other organizations have a hard line against any approach dolphin mortality and have recourse against the U.S. government legislation requiring the recent ratification of international agreements. This paper is a story of the tuna-dolphin debate, starting with an analysis of tuna dolphin relationship. A chronological overview national and international developments in legislation regarding purse seine vessels FTE follows. Finally, two recent test, Brower v. Evans (13) and defender of the Wildlife v. Hogarth, (14) are discussed and analysed for their potential effects on the continuation of the discussion.
