A primary industry is concerned with the extraction of natural resources from the earth in their raw state. This can include activities like mining, fishing, logging, and farming. The focus is on extracting resources directly from nature, rather than processing or manufacturing them into finished products. Primary producers are involved in these economic activities and may sell their products to secondary industries, which transform raw materials into finished goods. Clearing and cultivation of land may be a part of primary industry if it involves activities like farming or logging, but it is not the only focus.
