GEOLOGY 1 Lecture Notes - Lecture 22: East Los Angeles College, Environmental Geology, Environmental Chemistry
Document Summary
Environment: a complex system with physical, biological, geological, ecological, and geopolitical aspects. (nimby- not in my back yard) Multidisciplinary approach: environmental geology, environmental chemistry, global climate change, biological diversity and ecosystems, environmental economics, environmental ethics and law, etc. Environmental crisis: population, environmental hazards, resource limitation and contaminations, environment ownership (both in space and in time) Geologic knowledge is used for problem solving. Optimize the use of resources to maximize environmental benefits for the society. Earth is our only source of habitats and resources. Land and water resources: use, planning, and management. Five fundamental concepts: population growth, sustainability, system and change, hazardous earth processes, scientific knowledge and values. Origin of earths system: lithosphere, atmosphere, hydrosphere, and biosphere. Facing limited resources: energy, soil, freshwater, forests, ocean fisheries, rangelands. Right now we have about 7. 4 billion, in december the estimated rate is nearly 7. 7 billion. By 2050, we will have about 3 billion more people s. Criteria varies in space and over time.
