On a human time scale, a renewable resource can
be replenished fairly rapidly (from hours to decades)
through natural processes as long as it is not used up
faster than it is renewed. Examples are forests, grasslands,
fisheries, fresh water, fresh air, and fertile soil.
在人類的時間尺度，可再生資源可以
補充較快（從幾小時到幾十年）
通過自然過程，只要它不使用了
速度快於它是新的。例子有森林，草原，
漁業，淡水，空氣清新，土壤肥沃和。
