Biology Today: An Issues ApproachBiology as a subject not only plays a major role within the scientific world but has broader implications that cross many boundaries. This work takes a modern and innovative approach to teaching introductory biology; it presents fundamental biological concepts within the context of current social issues. How do scientists affect our society at large? How are ethics and morals applied to the scientific world? Why are we racing to complete the human genome project, and who are we racing against? How do economic disparities between people and nations influence habitat destruction? Can plant science feed the world? Are the causes of cancer more genetic or environmental? The book seeks to help students think critically about these questions and to explore and assess the role that science plays in their world. |
