地球的资源按是否可以再生分为可再生资源和非可再生资源。对于可再生资源来说,在一定区域,一定时段内是有限的;对于可再生资源来说,则更是有限,因为不可再生,所以,用一点少一点,用完了就没了,如矿产资源。The resources of the earth can be divided into renewable resources and non renewable resources according to whether they can be recycled. For renewable resources, in a certain region, time is limited; for renewable resources, is even more limited, because of non renewable, so with a little less, run out of no, such as mineral resources.
