Genetic engineering, and related research, is helping to shape the future of humankind. Over the past two decades scientists have made impressive breakthroughs. They have used the technology to discover cures for diseases, solve crimes, and develop drought-resistant crops that can be used to feed millions of people. However, not everyone is excited about the potential benefits of this technology. Some people believe that it is not right for scientists to interfere with nature; others are concerned about unknown health issues related to genetically modified organisms. These are difficult but intriguing ethical issues. This book will examine the science behind genetic engineering, discuss how scientists work with and modify genetic information, and explore some of the questions this new science raises.
