    The objective of this unit is to introduce you the book's topics as well as the rigors and structure of science. Science and mathematics are not just for scientists. A base understanding of these subjects is crucial in our very complex modern world. Without a solid understanding of how science and mathematics play a role in our everyday lives, we cannot respond appropriately in everyday situations, know how to vote on scientific laws, or hold public representatives responsible for their decisions on scientific policy.

    • 1.1: What is Environmental Science?
      This page discusses environmental science as an interdisciplinary field that explores interactions between human and natural systems, emphasizing sustainable resource use. It highlights the "Tragedy of the Commons" to illustrate issues arising from unregulated resource exploitation and presents global stress indicators such as deforestation and biodiversity loss.
    • 1.2: Themes and Concepts of Biology
      This page provides an overview of biology as the study of life, highlighting key characteristics that define living organisms and their complex organization from cells to ecosystems. It covers taxonomy's hierarchy and significance, including Linnaeus's naming system and Woese's work on phylogenetics. Additionally, the relevance of biological knowledge in forensic science is discussed, showing how biologists apply scientific methods to analyze crime-related evidence.
    • 1.3: The Process of Science
      This page provides an overview of biology as a systematic study of life, highlighting the scientific method's role in inquiry through observation, hypothesis formation, and experimentation. It distinguishes between basic science, which expands knowledge, and applied science, which addresses real-world issues. Key concepts discussed include deductive reasoning, experimental variables, and the importance of peer-reviewed publications for communication of findings.
    • 1.4: Introduction to Biology (Exercises)
      This page covers fundamental themes in biology, emphasizing the cell as the smallest unit of life and the hierarchical structure of biological organization, culminating in the biosphere. It introduces the scientific method, including the role of hypotheses and inductive reasoning in drawing conclusions from observations. The page also illustrates the study of biology across different scales and offers examples of applied science, such as the societal benefits of vaccines.
