Document Summary
Large change natural in environment axial wobble, variation of tilt, variation of orbit: many theories of astronomical processes not humans. Power of each process may be changed by humans (act to divert natural flows of energy/matter like sun/water) change balances within atmosphere, biosphere, hydrosphere and pedosphere (soil) All resources are finite at some scale. Human activities that bring persistent change to environment. E. g. agriculture: change results from replacing diverse mix of surface veg with a monoculture and replaces natural soil nutrients with chemical equivalents . Hard to define requires value judgement. Anthropocentric view not simply a thing or substance. It is the function that that thing performs or operation that thing takes part. Based on needs and wants of people/group. S. t. e. p scientific, technological, economical and/or political experiences of culture that effects their view of resources. Biocentric view we assume the rights of non-human resources to perceive the views of the ones we want.
