Thesis Statement: When Hammond and a portion of his associates thought they were in control, the tables turned and little did they know that the dinosaurs had gained control of more than just Jurassic Park but also their lives. When Hammond thought he and his associates had complete control of Jurassic Park, Nedry, who knew how to manually hack into the computer system, cut off the electricity to the entire park. Nedry was hired by another company to steal dinosaur embryos. The dinosaurs were no longer held captive. The dinosaurs began to attack and began 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 dinosaur DNA. The DNA of amphibians allowed them to reproduce. (375) When asked the question about dinosaurs' ability to reproduce, Hammond refused to believe it. If when the computer counting was off, he tried to dismiss it as other smaller animals. (163) Hammond and Dr. Wu were offended that it was dangerous, which made them dismiss it very quickly. (77/111/92) The reality then came to light, when Hammond encountered the dinosaurs himself. Jurassic Park was designed to fascinate dinosaurs similar to the way zoos fascinate animals. (Crichton) According to the article The risk of zoos as potential pathways for the introduction of non-indigenous species, zoos have had an increasing rate of accidental release of animal species. The fences were not as protected as they should have been. (Fabregas, Guillen-Salazant and Garces-Narro) Such escapes result in attacks as described in articles such as Zoo escape attack unleashed lawsuit and Animal escape artist: what zoos must learn from Tatiana. (Zoo Safety). According to Zoo Escape Attacks Trigger Lawsuits, “On Christmas Day 2007, 17-year-old Carlos Sousa was walking around the San Francisco Zoo with friends when a 350-pound Siberian tiger named Tatiana escaped from her adult enclosure felines and fatally mauled the The tiger slit Sousa's throat, clawed and bit the San José teenager'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. There have been seven occasions nationwide where the animals escaped and attacked.
