Course 3.1, Section I Course 3.1, Section I Successes and Failures of Technology in Relation to Environment Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems Course 3.1 Environmental Science and Technology for Decision Makers Developed by AIT for Tongji University
Successes and Failures of Technology in Relation to Environment: Urban Environmental Problems: Understanding the Scale 3 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Successes and Failures of Technology in Relation to Environment: Urban Environmental Problems: Understanding the Scale 4 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Successes and Failures of Technology in Relation to Environment: Urban Environmental Problems: Understanding the Scale Key to effective policy formulation Allocation of resources to project components o o Collection of data & information at appropriate level Identify resources & Stakeholders that function & involved in particular scale Formulate policy & take appropriate action at appropriate level o o o by using Science and Technology o 5 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Science and Technology: Science A search for understanding of the natural world Often leads to technological developments Limited by the technology available Not in direct contact in our daily lives Technology Application of scientific knowledge to benefit human beings New technologies lead to scientific discoveries In contact with products of science - technological devices such as Computers, iPods, Microwave Ovens, etc. 6 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Environmental Science: Group of Sciences that attempts to explain...... How LIFE on Earth sustained? What LEADS to Environmental problems? How these PROBLEMS be SOLVED ? Group of Sciences that attempts to explain...... Ecology (Part of Biology dealing with relationships among LIVING things and their environment) Geology Hydrology Climatology Meteorology Oceanography Soil Science 7 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Environmental Science: Why to Study? DEPEND on OUR environment LIVE only in an environment with certain kinds of CHARACTERISTICS and within certain range of availability of RESOURCES Modern science & technology to affect the Environment To understand how the Environment works To LIVE within its CONSTRAINTS People vis-a-vis Nature What is the NATURE like when UNDISTURBED by PEOPLE? What are the EFFECTS of PEOPLE on the NATURE? What are the EFFECTS of NATURE on PEOPLE? Environmental Science Modern way to seek answers to these questions. To keep Environment Enjoyable Understand it Scientifically Healthy Environment help to live LONGER & FULFILLING LIFE 8 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Environmental Science: Major Themes Human Population Growth - (Is it the environmental problem?) Sustainability - (Is it the environmental goal?) Global Perspective - (Does solving many environmental problems require a global solution?) An Urbanizing World - (Does we live and work in urban area?) People and Nature - (Does we share a common history with nature?) Science and Values - (Does science provide solution?) 9 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Environmental Science: Major Themes Human Population Growth - (Is it the environmental problem?) Rapidly increasing human population Earth not grown any larger Abundance of Earths' resources not increased What is the maximum number of people that could live on Earth? Not for a short time, but SUSTAINED over a long time? 10 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Environmental Science: Major Themes Sustainability - (Is it the environmental goal?) What is the maximum number of people the Earth can sustain? OR What is the sustainable human carrying capacity of the Earth? o Using RENEWABLE resources faster than they could be REPLENISHED (i.e. using resources UNSUSTAINABLE) o Must learn to sustain environmental resources Continue to provide benefits to people and other living things on our plants 11 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Environmental Science: Major Themes A Global Perspective - (Does solving many environmental problems require a global solution?) Recent common belief: Human activity caused only local, or most regional, environmental change Now we know: Human activities affect the environment globally (e.g. burning of fossil fuels may change climate) o Life affects the environment at a global level 12 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Environmental Science: Major Themes An Urbanizing World - (Does we live and work in urban area?) With economic development comes urbanization People move from farms to cities and suburbs Cities & Towns increase in size Wetlands filled in, forests cut, soils covered over with pavements & buildings o Now more emphasis on urban environment o Effects of urban environments on the rest of planet 13 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Environmental Science: Major Themes People and Nature - (Does we share a common history with nature?) People & Nature intimately integrated Each affects the other We depend on nature o DIRECTLY for many material resources (wood, water, oxygen, etc) o INDIRECTLY for "public service functions" (soil, atmosphere, ozone layer, trees, wetlands, etc We affect nature o Using tools (e.g. fire), impart change in nature Have evolved on and with the Earth (not separate from it) Need to celebrate our union with nature as we work toward sustainability 14 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Environmental Science: Major Themes Science and Values - (Does science provide solution?) Finding solutions to environmental problems involves gathering facts and understanding scientific issues of a particular problem Much to do with our systems of values and issues of social justice o To solve environmental problems, must understand our values and socially just potential solutions o Then apply scientific knowledge for specific problems and find acceptable solutions 15 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Environmental Science: Major Themes Human Population Growth Sustainability A Global Perspective An Urbanizing World People and Nature Science and Values Is there any linkages amongst these THEMES? Is there a need for SCIENTIFIC THINKING? 16 Module 3: Solid waste, Wastewater and Gaseous Emissions Treatment Systems
Thank You 17 Module 3: Waste Management Treatment Systems
