单词 depletable resources
释义 depletable resources

Resources which can be used only once. Examples include deposits of coal, oil or minerals. This is in contrast to renewable resources, which can be used without being used up, for example solar energy or tidal power. In many cases whether resources are depletable or renewable depends on how they are used. Over-cropping of land or deforestation may diminish future productivity, whereas moderate levels of use with regular replanting would allow the same resources to be used on a sustainable basis. It is not always known until too late just how intensively resources can be used before they become depletable.
