There are ten units in this course. These ten units provide you with a working knowledge of the scientific background required to address many environmental problems from biological and chemical perspectives. Starting with a board overview of current and emerging environmental issues, the first three units provide a framework helping you to master basic facts, concepts and terminology of chemistry and biology to undertake environmental studies. Units 4-5 lead you to insights into the finite availability of natural resources from the governing equations of conservation of mass and conservation of energy. Units 6-8 explore various aspects of urban environmental pollution and mitigation measures. To sum up, the last two units offer a basic appreciation of the meaning and scope of sustainable development particularly covering nature conversation, biodiversity and urban management.
Each of the study units presents at least one advanced subject, with elaboration of key concepts to help you fully digest the course content. Journal and newspaper articles are the main supplementary study materials. In addition, activities and self-tests are interspersed in each unit. Activities help you to explore and apply the concepts you are learning, while self-tests are useful for checking how well you have grasped the materials. Feedback to the activities and self-test questions is also provided. Throughout the course, we will assess your understanding of the course materials by means of assignments and a final examination.
Course materials
Study units
A brief description of each study unit is given below.
Unit 1 Current environmental problems
In Unit 1, we will give a brief overview of environmental studies by looking at the sources, causes and impacts of natural resource extraction and environmental pollution. You will find that massive urbanization, widespread industrialization, rapid economic development and soaring population growth have placed great demands on our environment and caused significant ecological damage. We will also discuss some recent environmental disasters to demonstrate the importance of environmental protection and sound management practice for long-term sustainable development.
Unit 2 Environmental chemistry and analysis
In Unit 2, we will take a deeper look at environmental chemistry. Environmental chemistry is the study of the sources, reactions, transport, effects and fates of chemical species in the air, water, the ground, and living environments and the effects of human activities thereon. The interchange of chemical species among various environmental spheres complicates environmental chemistry. Throughout an environmental system, there are variations in the temperature, mixing, intensity of solar radiation, input of materials, and various other factors that strongly influence chemical conditions and behaviour.
Unit 3 Environmental microbiology and toxicology
Considering the interrelationships among humans, other living organisms and the environment, environmental microbiology is a sub-category of environmental studies. More specifically, the major issues of environmental microbiology include the impacts that human activities have on other living organisms and vice versa, the effects of humans and other living organisms on the environment and vice versa, as well as the conservation of biological diversity. Ultimately, we seek the establishment of sustainable coexistence between humans and other living organisms. In Unit 3, we will choose some topics with the goal of covering the environmental microbiology you will need to understand the nature of pollution problems and their likely effects.
Unit 4 Material flow analysis
In Unit 4, we will cover some topics that illustrate the limited availability of material resources. Mass cannot be created nor destroyed. This is commonly called the 'law of conservation of mass.' This law reveals that the mass of a completely isolated closed system will remain constant over time. The unit will begin with the concept of the tragedy of the commons. Subsequently, selected metal resources and wood resources will be discussed. The unit will conclude with a discussion of material resource management. Dematerialization, substitution of materials, recycling and the extraction of useful materials from waste are important for effective material resource management.
Unit 5 Energy resources and consumption
There are various generic terms to describe energy. Energy is relative. Energy is convertible. Energy is war. Energy means economic development. In Unit 5, we will examine these in detail. We will show you how to distinguish between population and species, habitat and niche, community and ecosystem, explain how abiotic and biotic factors influence ecosystems, examine the global energy crisis and the underlying science, outline the development of the modern energy industry ecosystem, and describe the fundamentals of carbon sequestration.
Unit 6 Ambient and indoor air quality control and monitoring
In Unit 6, we will select some topics to help you understand ambient and indoor air quality and their likely effects. Air is necessary for most organisms to survive on the earth, and is one of the most vital natural resources for humans. We know that the emission of toxic chemicals and particles into the atmosphere creates air pollution and causes deterioration in the air quality of surrounding areas. We want to maintain air quality not only to prevent undesirable health effects but also the adverse financial implications of diseases, illnesses and property loss and damage.
Unit 7 Water quantity and quality issues
An adequate supply of clean water is essential to the survival of life. Very often, water resources refer to the current and future availability of water for both municipal and industrial uses. Water is an important natural resource and there is no substitute for it. In Unit 7, we will go through some selected topics covering major water quantity and quality issues. This is essential for understanding water resources in the scheme of sustainable development.
Unit 8 Solid and hazardous waste management
Waste is commonly referred to as 'solid waste,' though some waste, especially chemical and hazardous waste, is liquid. Hong Kong is a developed economy characterized by consumption which generates lots of waste. Solid waste has become a headache. Apart from the thermal destruction process of waste, biology and chemistry are applied to understand the biological and chemical effects of waste on the environment, and in the development of various biological and chemical treatment methodologies. In Unit 8, we will show you how to categorize solid wastes into non-hazardous and hazardous wastes, explain the properties of each type of waste, and outline the basic methodologies in municipal solid waste and hazardous waste treatment and management.
Unit 9 Nature conservation and biodiversity
In Unit 9, we will cover some topics that illustrate the importance of nature conservation and its contribution to economic growth and sustainable development. The traditional expression 'Mother Nature' suggests the life-giving and nurturing features of the earth and its biosphere. The natural environment and biodiversity, which is a key element in nature conservation, are increasingly threatened by human disturbance and urban development. Preserving biodiversity has both direct and indirect benefits for human beings. This unit will begin with biological resource analysis followed by a discussion of the reasons for a loss of biodiversity. Lastly, the management of endangered and extinct species will be discussed.
Unit 10 Global environmental outlook and strategic urban planning
As the course title suggests, this course is designed to stimulate us to think about the application of biology and chemistry in environmental studies. In the previous units, you learn about various biological and chemical processes, for example, in creating 'food' by plants, the formation of dioxin, composting, treating hazardous waste with plants, and so on. Unit 10 providesan overview of the application of biology and chemistry in relation to our ecosystem and how governments are responding to that.
Set textbook
As the goal of this course is to introduce you to current issues in environmental studies from the perspective of biology and chemistry, the course content will be largely based on journal articles and no set textbook is required.
Readings
You may be instructed in the study units to read articles or other supplementary materials. These will be available online or provided as hard copies at the backs of the study units. For online readings, instead of typing in the URL, you can click the link in the online study unit provided in the OLE. Study units give further guidance on these readings, and set out the learning approach for self-instruction.
