GEOG 106 Lecture Notes - Lecture 18: Non-Renewable Resource, Social Movement, Stone Age
Document Summary
Environmental sustainability is defined as maintaining or restoring the quantity and quality of the biophysical resources upon which human depend. Rule 1: the movement of natural resources from the natural environment to us. For renewable resources: the harvest or consumption rate of renewable resources must be within the regenerative capacity of the natural system that generates them, we can use no more than nature provides us with. If we do, then we are mining the resource whereby it becomes more like a stock resource. For non-renewables: depletion rates of non-renewable resource should be equal or less than the rate at which renewable substitutes are developed. Rule 2: the movement of used natural resources from us back into the environment. If we follow this output rule, we will be able to maintain the quality of the environment forever (in spite of dumping our waste in it, forever).
