Document Summary
Environmental sustainability and problem displacement: environmental sustainability: maintaining or restoring the quantity and quality of biophysical resources upon which humans depend. Types of impacts affecting environmental sustainability: changing the quality/chemistry of the biophysical environment, changing the biodiversity of the biophysical environment, changing the structure of the biophysical environment, changes to the supply/storage of biophysical resources. Sudbury smelting pushed through super stacks affecting sugar maples in quebec because it creates acid rain: displacement to another medium: gas, liquid, solid. Scrubbers on stacks to prevent more waste for entering the atmosphere than can be assimilated. This scrubber causes liquid sludge that we don"t know what to do with: temporal displacement: dumping into the ocean. We don"t know where to put waste or what to do with it. Introduction: most current evidence indicates that early hunter-gatherer societies were successful practicing ecologists, early humans: tools opposable thumbs domesticated fire ecological knowledge.
