We can change the world with genetic modification—but should we?    CRISPR stands for clustered regularly interspaced short palindromic repeats. If it sounds complicated, it is—but it’s also one of the most powerful ways we can shape the future. And it’s poised to completely upend the way we think about science.   Author Yolanda Ridge tackles this topic in a friendly and accessible tone, with two introductory chapters covering the basics of DNA and genetic modification before taking readers through the ways that this ground-breaking science could affect them by potentially: -          eliminating diseases like malaria and cancer,   -          improving the stability of our food supply, and -          helping to manage conservation efforts for threatened animals and environments.   But all of these possible advancements come with risks, the biggest being that the consequences are unknown. Chapters end with “Stop, Go, Yield� sections encouraging readers to consider the pros and cons of using CRISPR. “Cutting Questions� give readers the opportunity to further reflect on the ethics of the science.   CRISPR is a game changer. This important book, with detailed scientific illustrations, brings much needed clarity to a topic that will affect readers for generations to come.
