Thesis Statement: When Hammond and some of his associates thought they were in control, the tables were turned and little did they know, the dinosaurs had taken control of well more than Jurassic Park, but Their lives as well. Just as Hammond thought he and his associates had complete control of Jurassic Park, Nedry, who knew how to manually enter the computer system, shut off the power to the entire park. Nedry was hired by another company to steal dinosaur embryos. Dinosaurs were no longer held captive. The dinosaurs began to attack and went on a killing spree. Dr. Wu labeled them with version numbers as if they were some kind of software. Dr. Wu also combined the DNA with amphibian DNA to reconstruct the DNA of a dinosaur. The DNA of amphibians allowed them to reproduce. (375) When the question of dinosaurs' ability to reproduce arose, Hammond refused to believe it. If, when the computer count was wrong, he tried to dismiss it like other smaller animals. (163) Hammond and Dr. Wu were offended by the mention of the dangerousness, leading them to dismiss it very quickly. (77/111/92). The reality then came to light when Hammond encountered the dinosaurs for himself. Jurassic Park was designed to captivate dinosaurs in the same way zoos captivate animals. (Crichton)According to the article entitled The Risk of Zoos as Potential Pathways for the Introduction of Non-Native Species, zoos have experienced an increasing rate of accidental releases of animal species. The enclosures were not secured as they should have been. (Fabregas, Guillen-Salazant, and Garces-Narro) Such escapes result in attacks as described in articles like Zoo Escapes Sparked Lawsuits and Animal Escape Artists: What Zoos Need to Learn from Tatiana. (Zoo Safety). According to Zoo Escapes, the attacks sparked legal action: "On Christmas Day 2007, 17-year-old Carlos Sousa was walking through the San Francisco Zoo with friends when a 350-pound Siberian tiger named Tatiana s escaped from his big cat enclosure and fatally mauled the The tiger slit Sousa's throat and scratched and bit the San Jose teen's friends, Paul Dhaliwal, 19, and his brother Kulbir, 23 , who were hospitalized for four days after the attack They go on to say that Tatiana's enclosure was not deep enough according to the Association of Zoos and Aquariums. animals escaped and were attacked..
