Document Summary
Global environmental change (gec): the set of biophysical transformations of land, oceans, and atmosphere. Natural processes (movement of tectonic plates, volcanic eruptions, tornadoes) Human activities (deforestation, burning of fossil fuels) Anthropogenic climate change: driven by increased levels of greenhouse gases in the atmosphere. Systematic gec"s: those that impact systems that span much of or the entire planet i. e. the oceans or the atmosphere. Cumulative gec"s: arise from local events or change i. e. deforestation in russia won"t affect canada. Technology i. e. development of fossil fuel technologies. Sociocultural factors- economic, political, social values, governing structures i. e. the laws that govern the use of resources. Ignorance i. e. a lack of understanding of how environmental systems operate, not knowing how our individual actions affect the world. Ownership of resources i. e. tragedy of the commons. Valuation- without an economic value on clean water or biodiversity, it is easy to exploit it. We must lower human population levels to avoid stressing our life support (ecological) systems.
