background image Geology and Human Affairs – Week 1 The Science of Geology
Geology: Science that peruses an understanding of the Earth
1. Compositions (aspect of chemistry)
2. Structure (aspects of physics, natural laws)
3. History of earth and its life (aspects of biology, understanding of life forms) Environmental Geology: Use geological information to solve conflicts in land use, 
degradation, resource utilization, etc.
Components of Environmental Geology The application of geology to these problems includes the study of:
1. Earth materials: minerals, rocks, soil
2. Hazards: floods, earthquakes, coastal erosion, landslides, volcanic activity
3. Land­use planning and environmental impact
4. Hydrologic processes: surface rivers, groundwater, water pollution Earths Place in Space
Earth: Geospatially isolated in the universe
Origin of earths system: Lithosphere, atmosphere, hydrosphere, and biosphere
Facing limited resources: Energy, soil, freshwater, forests, ocean fisheries, rangelands
Environmental Science Environment: A complex system with physical, biological, geological, ecological, and 
geopolitical aspects. 
Requires multidisciplinary research: Environmental geology, environmental chemistry,  global climate change, biological diversity and ecosystems, environmental economics, 
environmental ethics, environmental law, etc. 
background image Geology and Human Affairs – Week 1 Environmental crisis: Population, environmental hazards, resource limitations and 
contaminations, environment ownership (both in space and over time)
Environmental Geology Environmental geology: Applied geology  Environmental geology knowledge:  To better understand environmental problems 
Geologic knowledge for problem solving 
Minimize environmental degradation 
Optimize the use of resources to maximize environmental benefits for the society
Earth: Source for habitats and resources, waste disposal, environment and health  issues  Better understand the natural hazards Land and water resources: Use, planning, and management  Geologic aspect in every environmental condition Fundamental Concepts
Five fundamental concepts: 
1. Population growth
2. Sustainability
3. Earth as a system 
4. Hazardous Earth processes 
5. Scientific knowledge and values
background image Geology and Human Affairs – Week 1 Other important concepts are related to environmental geology Finite resources, obligation to future Human Population Growth The number one environmental problem: increasing in human population, nearly 7  billion by the year 2010  Exponential growth: (Population bomb?) 
a. Growth rate (G): Measured as a percentage 
b. Doubling time (D): the time it takes for whatever is growing to double, 
D=70/G 
Population is already above a comfortable “carrying capacity” for the planet: using more  resources, need more land space, generate more waste  Earth is our only suitable habitat: resources are limited, some are renewable like water, 
but many, such as fuels and minerals, are not.
Sustainability The developments that are economically viable, not destructive to the environment  which ensures that future generation will have equal access to the resources that our 
planet offers. 
Sustainability is an environmental objective:  A. Expectation and reality
