Revised and updated to reflected new information in the field, the Third Edition of Alcamo’s Microbes and Society is intended for liberal arts students taking a foundation course in the life sciences. It discusses the role of microbes in our everyday lives, from food production to their roll in biotechnology and the numerous other ways that microbes contribute to our world. It goes on to explore such topics as the function of microbes in ecological systems and environmental systems. Coverage of bioterrorism, antibiotic resistance, and microbial disease offer students a broad and current perspective of the extensive impact of various microbes. Consistent with Edward Alcamo’s student-friendly writing style, material is presented in a lively format that will engage students and highlight both the positive and negative impact that microorganisms have in our society.
