In both passages, the authors discuss the scientific aspirations associated with animal cloning, albeit from different perspectives. In "The Dangerous Side of Cloning Animals" by Phillip Jones, the author highlights concerns about cloning's ethical implications and potential consequences, suggesting that scientists hope to push boundaries in genetic research, which could lead to advancements in understanding animal biology. He indicates that the clone experiments aim to "provide insights into genetic diseases."
Conversely, in "Lower the Greenhouse Effect: Clone Mammoths" by Samuel Viler, the author presents a more optimistic view, emphasizing how cloning mammoths could help address climate change. Viler notes that scientists are motivated by the hope that bringing back mammoths could "restore ecosystems" and potentially combat the greenhouse effect.
Together, these texts illustrate contrasting reasons behind scientists' hopes for cloning: one focuses on health and genetic understanding while the other emphasizes ecological restoration and climate solutions.
