Petco's across the Untied States have been slaughtering marine life and continue to do so everyday without regard for the rarity of any species. Every week Petco receives shipments of fish, coral, and other invertebrates and houses them in uninhabitable conditions. These aquariums lack the proper environment that these animals need to survive. Expertise and proper habitat are pertinent to the preservation of these precious animals. Workers at Petco rarely know the requirements and procedures that are vital to the existence of these animals. They consistently ignore imperatives, such as, the proper lighting, water quality, and nutrition needed to sustain these life forms. As these animals die week after week, Petco continues to condone more casualities, as they ship more animals into their stores while knowing that their fate will be same as those who have gone before. They see them as mere replacements, and the only number they care about are profit margins. "Coral reefs around the world are dying at an alarming rate. Lining 60,000 miles of shoreline along 109 countries, reefs and their related fisheries, marshlands and lagoons are vanishing. Home to more than a quarter of all fish species on Earth, an estimated 25% of coral reefs have already disappeared and an estimated 67% of all coral reefs are at risk today." (Reefs At Risk, World Resources Institute, 1998) As coral reefs around the world are threatened it must be our duty to protect this precious life forms and stop the senseless killing of marine life by Petco. The goal - stop Petco from selling marine animals or require them to keep these animals in the proper environment and employ professionals who know how to care for them.
