Why is soil considered a non-renewable resource?
Soil is a thin layer of material on the earth’s surface covering most land. It is a natural resource containing both organic and inorganic particles. Soil is an important natural resource on earth made up of air, water, and minerals. Soil is one of the most valuable natural resources on the earth. It is a source of food for many living organisms directly or indirectly.
Soil is a Non-renewable Resource
Soil is considered a non-renewable resource meaning once used it cannot be recovered during a human lifespan. Soil takes hundred to million years for replenishing. Fertile soil is in short supply and requires many years to form back. Due to erosion, the soil may use its fertility and these soils are no longer of any good use. Soils are used for various human activities such as agriculture, cropping, forestry, and urbanisation. With growing population, the need of sustainable soil practices is needed more than ever. However, the necessity of soil and its usage is often neglected and overlooked as compared to other natural resources. Hence, soil is a non-renewable resource which needs to be preserved and used wisely for a sustainable future.
