Why is there a question of limited resources?

Economic resources are sources, means of ensuring production (natural, labor, capital, energy, financial and informational).
Economic resources are divided into reproducible (labor, capital, financial, informational, as well as electricity) and non-reproducible (natural, energy). The limited economic resources are due to non-renewable resources: natural (land, water, air, mineral raw materials, flora and fauna) and energy (coal, oil, gas). The reserves of non-renewable resources in the world are limited, the need of society for these resources is always greater than the possibility of their satisfaction, thus there is a need to reduce the consumption of natural goods.
