This course's aim is to provide a scientific foundation of environmental science, identify key environmental problems and discuss scientific aspects of addressing these problems. The course covers the fundamentals of environmental science, sustainability science, environment as a system, systems and chaos theory, earth system, energy systems, urban environments, environmental change, and environmental impacts; and scientific foundations of the key environmental issues including air pollution, ozone depletion, climate change, global warming, water pollution, marine pollution, land pollution, genetic pollution, noise pollution, chlorofluorocarbon, nuclear waste and emissions, electronic waste, loss of biodiversity and resource degradation. The scientific aspects of these environmental issues will be analyzed using a systems approach and case studies will be used to investigate such issues in real-life context.
