SELECTED TOPICS IN ENVIRONMENTAL PROTECTION TECHNOLOGY (EPT 1217) DR: WAEL M. HASSAN Lecture One Introduction What Exactly is “the Environment”? “The complete range of external conditions, physical and biological, in which an organism lives. Environment includes social, cultural, and (for humans) economic and political considerations, as well as the more usually understood features such as soil, climate, and food supply.” What is Environmental Science? Environmental science Is the dynamic, interdisciplinary study of the interaction of living and non-living parts of the environment, with special focus on the impact of humans on the environment. The study of environmental science includes circumstances, objects, or conditions by which an organism or community is surrounded and the complex ways in which they interact. What are Environmental Issues? Issues are important topics or problems that can be discussed or debated. Environmental issues are important topics or problems that relate to the environment, are often revealed through environmental science, and provoke discussion or debate in human societies. These issues typically endanger human health and/or the sustainability of human society. “A Debate" is typically two or more people discussing a particular subject or topics and each hold opposite views on the subject matter. “A Discussion” is typically two people speaking on a subject that both agree or mostly agree with each other on the subject matter. Why Study Environmental Science and Environmental Issues? The need for equitable, ethical, and sustainable use of Earth’s resources by a global population that is outpacing the carrying capacity of the planet requires us not only to understand how human behaviors affect the environment, but also the scientific principles that govern interactions between the living and non-living. Our future depends on our ability to understand and evaluate evidence-based arguments about the environmental consequences of human actions and technologies, and to make informed decisions based on those arguments. Why Study Environmental Science and Environmental Issues? From climate change to habitat loss driven by human population growth and development, Earth is becoming a different planet—right before our eyes. The global scale and rate of environmental change are beyond anything in recorded human history. Our challenge is to acquire an improved understanding of Earth’s complex environmental systems. Cont. : Why Study Environmental Science and Environmental Issues? These systems characterized by interactions within and among their natural and human components that link local to global and short-term to long-term phenomena, and individual behavior to collective action. The complexity of environmental challenges demands that we all, as citizens, participate in finding and implementing solutions leading to long-term environmental sustainability.
