Document Summary
Natural resources: various substances/energy sources we need to survive, can be viewed as continuum from most to least renewable. Renewable natural resources: aka rnr, natural resources replenished over short periods of time, some are inexhaustible/perpetual, some can become non-renewable if rate of use is higher than renewal rate, ie sunlight/wind. Renewable resources: aka stock/flow resources or rr, can be harvested by rules living resources, regen rate limited by rates of physical processes, ie groundwater/soil. Resource management: to balance rate of withdrawal from stock/rate of renewal or regen, used to balance resource use with its preservation. Stock: harvestable portion of resource, if taken faster than replenished it will eventually deplete, Non-renewable natural resources: aka nrnr, finite supply/depletable, formed much slower then use, mineral mined, minerals require conservation/reuse/recycle, some resources truly non-renewable/can only be used once, ie fossil fuels/mineral deposits. Minerals: civ depends on many, mined nrnr but can be part of conserve/recuse/recycle.
