it uses alot of earths energy.
it is easily transported.
Soil is considered to be a nonrenewable natural resource primarily because it takes a very long time to form. The process of soil formation involves weathering of rocks, decomposition of organic matter, and the accumulation of minerals and nutrients over thousands of years. This slow formation rate means that soil cannot be easily or quickly replaced once it is eroded, degraded, or depleted.
