GEO 100 Lecture Notes - Lecture 1: Environmental Geology, Covalent Bond, Coastal Erosion
Document Summary
Environment- the sum of all features and conditions surrounding and organism that. Environmental geology- refers to geology as it relates directly to human activities. Considered one of the most dangerous volcanoes in tge world. Toxic waste cleanup: cleanup costs have been estimated to be 20 trillion, difficult to estimate the long term effects. From a population of 1 billion at the beginning of the 19th century, our species now numbers >7 billion people. The environment: physical, chemical, and biological factors. Environmental resources seen as endless 150 years ago. Now resources are limited and need management. Sustainability- maintaining the ability to accommodate three important sources of change: the world is changing. Environments are under constant change: we are changing. Technology changes our needs for ecosystem services: we are changing the world. Growth: sustainability, system and change, hazardous earth processes, scientific knowledge and values. Other important concepts in environmental geology: finite resources, obligation to future.
